Installing the door peephole

The peephole is a part of the front door, without which we cannot imagine life for a long time. This is a kind of pass to our home: we see the guest and decide whether we want to let him in or not. Modern models of the door peephole even allow you to monitor what is happening on the staircase remotely, from the office or while on vacation. The market provides a huge selection, so you can find something for your liking, requests and wallet.

How the door peephole works

Do not forget that the peephole is an optical device. Therefore, it cannot function without two main components: an eyepiece and a lens. The peephole body can be made of metal or plastic. When choosing quality, give preference to metal.

Fisheye is also an integral part of the classic door peephole. It is designed to magnify the image, so people appear much larger through the peephole. Also in the case are lenses, from two to fifteen pieces. The number of lenses depends on the length of the device and is responsible for the light transmission.

Lenses, in turn, can also be of two types: glass and plastic. Plastic is relatively cheaper than glass, but it quickly breaks down and loses its crystal transparency. You will find the first signs of aging in 2-3 years. Therefore, it is better to purchase a peephole with glass lenses. Additionally, some of the door eyes are equipped with armor-piercing glass lenses.

The size of the device varies with the thickness of the door leaf. The metal sheet is thinner than wood, but layering is practiced in modern doors, so a steel door may be thicker than an old wooden door. There are door eyes of the following size:

30-55 mm. This is the thickness of a standard front door;
55-100 mm. Doors with cladding or decorative elements;
More than 100 mm. Armored doors, which are more often used in guarded objects, in warehouses for especially valuable goods.

The viewing angle of the peephole ranges from 150 to 200 degrees. A 180-degree view is considered optimal: this way you will see both your face and a significant part of the staircase.

When choosing a door peephole, pay special attention to the class of the door itself.

Peephole: types

Standard... The eyepiece and lens form a single line and are opposite each other. The simplest and most affordable peephole option. It is customary to install it on simple door models. But even taking into account the availability of this model, we recommend choosing eyes with glass lenses and a metal case - they will last longer.

Periscopic... It is a more complex design. There are two eyepieces on the inner side, and a lens on the outside. The image is transferred to the second eyepiece using mirrored lenses. Why is such a design needed? For convenient operation by residents of different heights. If there is a child in the family and you are afraid to leave him alone due to the fact that he will not be able to look through the peephole, install a periscope model for his convenience.

Secret... The outer part of such a peephole is located outside the door leaf, usually at the top or at the ends. Outside, no one will guess that a resident of the house can watch him.

Panoramic... The large eyepiece, large diameter of the body and the ability to look "in both eyes" are overshadowed by the difficulties in installation. Transmitting lenses are located inside the structure. But the viewing angle is extremely large - you can see the entire staircase.

Electronic peephole with a video camera... The most modern type of door peephole. It has the function of filming, recording and even broadcasting. Therefore, you can easily find out what happened on the site in your absence. We will consider this type of eye in more detail at the end of the article.

Installation of a peephole in a metal door

The principle of installing a peephole is identical for doors made of any material, be it steel, wood or veneer. When working with metal, there is only one fundamental difference - the thickness of the door and the density of the material. Therefore, you will have to spend more effort and choose a larger eye model. Moreover, metal doors are often supplemented with MDF interior cladding and decorative elements, which complicates the task somewhat.

Stages of mounting the viewing device in a metal door:

Using chalk or pencil, mark the location of the future peephole. Consider the height of all family members and choose an average.
To avoid deformation of the interior door trim or coating, stick foil or electrical tape at the drilling site.
Measure the diameter of the peephole body. If the part has an internal thread, use a drill half a millimeter wider than the result.
You need to drill from the inside, directing the drill to the outside of the door.
Do not drill through the door. Walk to the outer layer of the exterior trim and stop. Then drill from the outside. This little trick will help you avoid chipping, chipping, or bumps.
A lens is installed from the outside. From the inside, respectively, the eyepiece.
Connect both parts of the eyelet with a screwing motion.

Electronic door peephole: types, advantages, installation

A video peephole is a sophisticated type of device that makes life safer. Unlike classic counterparts, the electronic peephole is easy to use and has an impressive set of functions.

Kinds

Today it is customary to distinguish three types of electronic eyes:

Wireless with color recording function.Installed like a regular peephole. The image quality is inferior to monochrome and is more expensive. But it has the function of video recording in color.
Monochrome, infrared.Easy installation, IR illumination, convenient operation. The monochrome peephole will be a worthy alternative to the usual one.
Electronic black and white peephole complete with a matrix camera.Complex installation, image distortion, small monitor. From the pros - an affordable price.

Benefits

Despite the complexity of the design and installation, as well as the high price, the video peephole is gaining popularity. What is the reason? Consider the main advantages of an electronic analogue:

Displaying the image on the monitor. This is convenient for those who do not like to squint and close one eye. The panorama of the staircase is visible from a convenient distance.
Night vision function. IR illumination is convenient at night, when an ordinary peephole simply cannot cope with its main task.
Recording function. Suitable for those who are especially sensitive to security. You can be on the other side of the world, but know exactly what is happening in your entrance and who approaches the front door of the apartment. How it works? The peephole is connected to a computer or other device for data storage. Also, each model with a recording function has a microSD card slot.
Built-in motion sensors. An added bonus to the security system's piggy bank. Even in the dark, you know that someone is near the door. The system is adaptable both for residential buildings and for office premises and warehouses. It is an excellent addition to your basic room alarm system.
No need to apply for a license. Classic video surveillance systems are subject to mandatory licensing in a number of cases. The use of an electronic eye with a video recording function does not require a license. This is true for any purpose from private to commercial.

Installation of an electronic peephole in an iron door

Different types of electronic eyes are installed according to the same principle. However, the installation of each of them is worth observing the individual subtleties, which we will discuss below.

Set the exact thickness of your front door. In most cases, adapter rings are included in the video eye kit, but even they are designed for a certain size of the door leaf.

The size of the hole in the door directly depends on the diameter of the case. In most cases, a standard connector from an old peephole will work fine. In some cases, the diameter will have to be increased. This can be done using a puncher. To do this, select the nozzle of the desired diameter and drill in turn on each side, without going through. This will help to avoid external defects of the door leaf.

Next, install the camera into the hole and fix the monitor. Usually, the kit includes special bolts that can be easily screwed in with a screwdriver. If the peephole is wireless, fixing the case will be the final stage of installation.

Some models are mounted on the door itself or next to the hole from the old peephole. You need to carefully read the instructions, but it is better to contact a specialist.

There are also network-powered models. Additional manipulations are made with them in order to connect and mask the wire. It is not recommended to install such devices yourself.

Video eye connection: video

The choice of complexity, price and type of door peephole depends on such factors as: door class, financial capabilities and the need to increase the level of security. Consider the ratio of all these parameters during selection and installation. Metal doors Guardian correspond in their technical characteristics to any type of peephole. In order to increase security, you can order a door with an additional armored leaf or decorative elements to your taste.

Embed a panoramic peephole and other types

If you do not know how to assemble a door peephole, then this review is for you. In it we will analyze the main types of products and their features.

You will also learn how to properly install standard and more modern solutions. To carry out all the work quickly and efficiently, you need to follow a few simple recommendations from the corresponding section.

If in the eighties one could find 1-2 variants of products on sale, then today the choice is much wider. Therefore, first you should decide on the type of construction that suits you best, and only then figure out how the installation is performed.

Types of eyes

You can choose from the following options:

Standard products... The device of this type of door peephole is known to everyone: a lens on one side and an eyepiece on the other. The simplest solution, which has a small viewing angle: if someone stands to the side of the wall, you will not see him. As for the advantages, the most important of them is the low price, this is the most budgetary modification of the eyes;

Mirror-coated eyes. This option has exactly the same design as the classic one, but has one important advantage. The outer part of the lens is made in the form of a mirror, and the one who is outside does not see the light from the peephole and cannot determine whether someone is looking from behind the door or not. This is a good option for dark porches where the light from the peephole is visible;

Bulletproof products. In appearance, they do not differ from ordinary ones, but in terms of reliability they are ten times stronger than them, since they are made of bullet-proof materials;

Panoramic door eyes. Provides a complete view of the space in front of the front door. You will see both the landing and the walls on either side of the door. A good solution for those who don't want to install video equipment. The eyes most often have an increased diameter, which creates certain difficulties during installation, you should also not forget about this when choosing;

Double door systems... This option is required if you have two doors at the entrance. The design consists of two parts that must be installed correctly so that you can see what is happening outside without opening any door. If you need just such an option, then I recommend entrusting its installation to specialists - it is not easy to ideally combine the two parts of the system;

Periscope type eyes... As the name implies, the design of the products resembles a periscope. The eyepiece for viewing what is happening behind the door is offset from the lens to the right, left or down. Such a system is set up quite simply, and its additional advantage can be considered the fact that from the outside a person cannot determine whether someone is looking through the peephole or not;

Digital systems... A convenient modern solution consisting of a miniature camera and a display that is installed from the inside and transmits an image of what is happening outside the door. You don't need to look into the eyepiece - everything will be visible anyway, and you don't even have to turn on the light. The device runs on batteries, which is also convenient, because you do not need to pull wires;

Video system. An even more modern and progressive solution that allows you to transfer an image from a miniature camera to a smartphone or computer monitor. That is, you can watch who is behind the door without even getting up from the couch. Another advantage is the ability to connect multiple devices so that all family members can see who is calling at your door;

Video eyes with motion sensor... This option is even more modern - it not only transmits an image to a smartphone, but also has a built-in memory card and a motion sensor. The system starts when someone moves in front of the door, it records the image and saves it. When there is no movement, no recording is made, which is also very convenient.

Now you know what product options are. You need to choose the best solution and install it.

We will tell you how to do it yourself, relying on two options:

classic designs;
digital eyes.

Installation of a conventional peephole

Let's figure out how to insert a peephole if you have a new door or there is no hole in it for installing this element.

There is nothing difficult in work, but you need to have a certain set of tools at hand:

Illustration	Description
	Drill bit. With it, we will make a hole on the inside of the door where the MDF trim is fixed. The standard drill diameter is 20 mm. But if you have a peephole with a larger diameter, then the equipment is selected for it.
	Metal crown. With its help, we will drill a steel door, so the equipment must be reliable and of high quality. The design consists of a pilot drill and a carbide tip with a diameter of 20 mm or more. Advice! Choose a bit with a hex shank, it is much more convenient to clamp it in a screwdriver or drill.
	Screwdriver. It is with its help that we will carry out drilling. The tool must be powerful enough to drill through the metal. If there is no screwdriver, then you can use a small drill, but it is more convenient to work with a cordless tool, it is lighter and more mobile.
	A drill for metal is necessary in order to pre-drill a small diameter hole. This will allow you to make even cutouts for the peephole, since the crown will not slide over the surface, as it happens without preliminary preparation. You can use options with a diameter of 4 to 6 mm.
	A construction tape is necessary in order to be able to determine the exact location of the peephole. If you do everything without measurements, it may turn out that the structure is shifted to the side, and this spoils the appearance of the door.

Naturally, you must also have the peephole itself. Remember that the products can have different lengths, because the thickness of the door leaves varies in a wide range. In addition, choose the color of the coating, it should be combined with the hardware on your door.

Let's figure out how to assemble a door peephole. The instructions for carrying out the work look like this:

Illustration	Stage description
	The middle of the door leaf is determined. The process is very simple: you need to measure the total width of the door and halve the resulting figure. Then a small mark is made on the surface with a pencil or felt-tip pen.
	The height of the eyelet is determined. It all depends on the average height of those who live in an apartment or house. If the family members are of different heights, then the system can be positioned at a standard height of 150 mm. This is a generally accepted metric that works for most people. A mark is made at the intersection of the two dimensions. Advice! It is best to make the mark with a punch, so that there is a depression on the surface in which it is convenient to place the drill. This is to prevent it from slipping and scratching the skin.
	A drill with a diameter of up to 6 mm is placed on the screwdriver. Its tip is located on the previously made mark, after which you can start working. The drill goes through the inner lining of MDF easily and quickly, but the metal lends itself much worse. The most important thing is to make sure that the screwdriver is perpendicular to the surface of the door, otherwise it may be skewed and your peephole will become crooked. Important! The drill length must be at least 20 mm longer than the door leaf thickness.
	This is the result of the work. There should be a straight hole on the outside. If burrs have formed on the metal, they can be easily removed. Go outside and inside with a drill - and all the flaws will be removed.
	Next, a crown with a diameter of 20 mm is fixed to the screwdriver. The center drill is inserted into the pre-drilled hole, after which you can start working. Hold the tool perpendicular to the surface and do not press too hard so as not to deform the door leaf and damage the screwdriver. It is better to press with moderate force - the crown selects the metal gradually. You only need to drill the outer part of the door leaf.
	From the inside, the door is drilled with a feather drill. It is very important to fix it well and check before work whether it is reliably centered. If the drill dangles during rotation, then it must be fixed again. The workflow is simple: once you've gone through the outer skin and insulation, work can be stopped.
	Parts of the eye are tried on. Everything is simple here: first, make sure that the outer part is in place, then do the same with the inner part. If all is well, then you can start mounting.
	The assembly of the structure is very simple: it is necessary, holding the outer part of the structure, to twist the inner one clockwise. The work is done manually, no special tools are required. Screw in the peephole until it stops, at the end make sure it holds well and the inner cap is in the correct position.
	This is how a door looks like with an installed peephole. If everything is done correctly, then the structure will be tightly pressed to the surface along the entire diameter. In the same way, options with an increased baggage and periscope systems are installed.

Installation of digital peephole

Now let's figure out how to change the old-style door peephole to a more modern digital version. The work is also not very difficult, and the only thing you need is Phillips screwdrivers PH1 and PH2.

As for the process of installing a digital peephole, it looks like this:

Illustration	Stage description
	If you have a regular peephole installed, then no alterations are required. If there is no hole in the door, then it must be done according to the same algorithm as described in the section above. The diameter of the hole is selected in accordance with the size of your eye, be sure to check this parameter so as not to redo the work later.
	We check the completeness of the digital peephole, you should have the following: Digital display with metal frame for door attachment; Camera with a wire for connecting to the display; At least two inner bushings for a thin and thick door leaf; Assembly instructions in Russian with diagrams.
	Now let's figure out how to disassemble the peephole. The process is very simple: it is necessary, while holding the outer part of the structure, unscrew the inner element counterclockwise. If you did not manage to tear off the mount with your hands, then use a wide screwdriver that can be inserted into the slot from the inside and moved off the ground. Further, everything is very easily unscrewed by hand.
	The equipment is being prepared for installation. This applies primarily to the display unit. At the bottom of it there are two mounting screws, they are shown in the photo. You need to carefully unscrew them, after which you can take out the case of their installation frame. The screws are very small, so place them so they don't get lost.
	Next, you need to snap off the mounting frame and set it aside. And four batteries are inserted into the monitor unit. The number of batteries and their configuration may differ, so it is better to see what you need first and only then buy batteries.
	The outer part of the structure is installed. It looks like an ordinary peephole with the only difference that you need to pull a wire through the hole. There is nothing complicated about this, the main thing is to do everything carefully so as not to damage the wire and glass of the camera lens.
	While the lens of a regular door peephole can be positioned as desired, then in the case of a camera it is important to align it properly. Do not forget about this so that later you do not find the image upside down on the display. Note! The red dot serves as a reference point, it denotes the upper part.
	The internal mounting block is assembled. For this, the threaded insert is inserted into the hole in the mounting frame. Everything is very simple, the most important thing is to choose the required insert, usually there are two of them in the delivery set: one is designed for thin door leaves, and the second for thick ones.
	The inner part of the structure is put in place. The order of work is as follows: First, the camera wire is pulled through the sleeve; On the back of the frame there is double-sided tape for tight fixation, the protective layer is removed from it, the structure is leveled and pressed against the surface; The sleeve is twisted, everything is like in a regular peephole: the outer part is held, and the inner part is wrapped clockwise.
	The system is being tested. To do this, the camera wire is connected to the connector on the back of the case, and the display is put in place. Advice! You do not need to fix anything, first make sure that the structure is level and all functions are working. If there are any problems, it is much easier to solve them now. If everything is in order, then you can proceed to the last stage.
	The fixing screws are screwed in at the bottom of the case. Everything is easy here: check if the holes match, and carefully screw in the fasteners. Note! Do not use too much force - you can rip off the threads in the plastic case.

Output

Now you know what types of door eyes are, and how to insert it, just by following our recommendations. The video in this article will provide additional information on the topic, and you will become even better at understanding some important aspects.

The peephole has long become as necessary an accessory for the front door as the lock. It is one of the simplest and most affordable elements to ensure our safety. The door peephole makes it possible to protect yourself from visits by unexpected or unwanted guests. In addition, it allows you to assess the situation on the site in front of the door in case of any problems.

Classic door peephole

design

The design of a standard door peephole is simple:

Lens - located on the side of the platform in front of the entrance and provides its overview;

Eyepiece - located on the inside of the door;

Lenses tube;

Nuts - outer and inner.

The largest view that a convex outer lens has is considered to be 180º. But due to the fact that the picture at the edge is slightly blurred, many manufacturers began to produce eyes with a viewing angle of 200º. When using such a device, you can get a high-quality, clear image of the area in front of the door within 5 m.

The length of the peephole depends on the thickness of the door:

30-50 mm - standard;

55-100 mm - elongated;

From 100 mm - extra long.

Standard devices usually have 4 lenses, but depending on the length of the peephole body, their number can be different - from 3 to 15 pieces.

Extra-long and extra-long eyes are used for doors with various decorative coatings. The most commonly used standard devices. They are quite enough for ordinary metal or wooden doors.

In order to be able to discreetly approach the peephole, it is equipped with curtains that do not let light through from the apartment.

material of manufacture

The body of the peephole is made of metal or plastic. The first option is more expensive, but will last much longer. The eyepieces of the device can be glass or plastic. The latter are more resistant to damage, but they can fade over time and the image loses clarity. Metal models with glass lenses are more expensive than plastic counterparts, but this is justified by their quality and reliability. There are bulletproof and shockproof eyes, but these properties of the products, of course, are reflected in their price.

installation of door eyes

It is not difficult to install classic door eyes - at a height that is convenient for all adult family members, you need to stick masking tape and make markings. Then drill on both sides of the door leaf. The hole must match the diameter of the optical device housing. The eye tip with an external thread is inserted into the hole on the outside of the door and is tightly screwed on the inside by the viewfinder with an internal thread.

Types of door eyes

In addition to the usual standard peepholes, there are modern products that make it as easy as possible to observe the site in front of the entrance to a house or apartment.

panoramic door peephole

Panoramic door viewer is a special model, the lens of which is divided into two lenses. They have a wider horizontal light receiving angle and do not require very close proximity to the eyepiece. The panoramic image on it can be seen from a distance of two steps and it is not necessary to stand directly in front of the peephole.

Installation of a panoramic door peephole does not take long. Each such device comes with a template with the necessary notes. It is glued to the outside of the door at the required height and a hole is drilled in its center with a drill. Then, with a Ø3 mm drill, four more indentations (5 mm) are made at the indicated marks. The outer cover of the peephole should fit snugly into the prepared holes. A peephole with a clamping ring is inserted from the inside of the web and is connected with clockwise turns to the outside of the device.

Peephole periscope

The eye-periscope differs in that its eyepiece and lens are located at different heights. Mirrors are installed inside the body of such devices, due to which light transmission occurs. Such devices are very convenient for families with children. Its components can be located both at the bottom of the door and at a normal height, convenient for an adult.

dwar peephole

The double peephole is installed on two doors - an external and an internal one. Both parts are located on the same line, which allows you to see the visitor without going to the second sash. The image quality depends on the distance between the doors. It is desirable that it does not exceed 2 cm.

video-eye

The video peephole works on the principle of a conventional hidden video camera, but differs from it both in purpose and in characteristics. It is ideal for observation in confined spaces in stairwells. The video peephole is equipped with IR illumination, which provides a good image even in the dark.

Signaling occurs in two ways:

Via the UHF radio channel - the video signal is converted into a radio frequency TV signal using a TV signal transmitter;

By cable - to the input of a monitor or TV.

A door peephole with a camera is installed on the canvas in the same way as a conventional classic peephole. When installing, keep in mind that the camera should not come into contact with metal. There are color and black-and-white video eyes. But the second option is preferable - such a camera has a higher light sensitivity.

Electronic door peephole

The electronic door peephole has recently appeared. It fits any door and fits in place of a regular peephole. The outer part consists of an infrared LED, a light sensor and a bell. With the help of a plate and screws, it is attached to the inner side of the door, the cable is connected to the indoor unit.

When you press the bell, the LCD screen turns on, displaying what is happening on the site. It can be noted that the viewing angle of such a device is slightly smaller than that of a conventional peephole. But it takes photos or videos that show the time and date of the visit - they are saved on a flash card. The door peephole with a camera is powered by AA batteries, so its installation does not require much effort.

By purchasing a peephole, the price of which is 30-50 rubles, you can be sure that it was produced in China or Belarus and, most likely, it will be a plastic product, and it will last only 2-3 years. There are also more expensive models of Belarusian, Russian, Spanish and German manufacturers on our market. The cost of devices with additional functions - panoramic, double, shockproof, bulletproof, etc. - starts at 1000 rubles.

Hold the tool perpendicular to the surface and do not press too hard so as not to deform the door leaf and damage the screwdriver. It is better to press with moderate force - the crown selects the metal gradually. You only need to drill the outer part of the door leaf.
	From the inside, the door is drilled with a feather drill. It is very important to fix it well and check before work whether it is reliably centered. If the drill dangles during rotation, then it must be fixed again. The workflow is simple: once you've gone through the outer skin and insulation, work can be stopped.
	Parts of the eye are tried on. Everything is simple here: first, make sure that the outer part is in place, then do the same with the inner part. If all is well, then you can start mounting.
	The assembly of the structure is very simple: it is necessary, holding the outer part of the structure, to twist the inner one clockwise. The work is done manually, no special tools are required. Screw in the peephole until it stops, at the end make sure it holds well and the inner cap is in the correct position.
	This is how a door looks like with an installed peephole. If everything is done correctly, then the structure will be tightly pressed to the surface along the entire diameter. In the same way, options with an increased baggage and periscope systems are installed.

Installation of a digital peephole

Now let's figure out how to change the old-style door peephole to a more modern digital version. The work is also not very difficult, and the only thing you need is Phillips screwdrivers PH1 and PH2.

As for the process of installing a digital peephole, it looks like this:

Illustration	Stage description
	If you have a regular peephole installed, then no alterations are required. If there is no hole in the door, then it must be done according to the same algorithm as described in the section above. The diameter of the hole is selected in accordance with the size of your eye, be sure to check this parameter so as not to redo the work later.
	We check the completeness of the digital peephole, you should have the following: Digital display with metal frame for door attachment; Camera with a wire for connecting to the display; At least two inner bushings for a thin and thick door leaf; Assembly instructions in Russian with diagrams.
	Now let's figure out how to disassemble the peephole. The process is very simple: it is necessary, while holding the outer part of the structure, unscrew the inner element counterclockwise. If you did not manage to tear off the mount with your hands, then use a wide screwdriver that can be inserted into the slot from the inside and moved off the ground. Further, everything is very easily unscrewed by hand.
	The equipment is being prepared for installation. This applies primarily to the display unit. At the bottom of it there are two mounting screws, they are shown in the photo. You need to carefully unscrew them, after which you can take out the case of their installation frame. The screws are very small, so place them so they don't get lost.
	Next, you need to snap off the mounting frame and set it aside. And four batteries are inserted into the monitor unit. The number of batteries and their configuration may differ, so it is better to see what you need first and only then buy batteries.
	The outer part of the structure is installed. It looks like an ordinary peephole with the only difference that you need to pull a wire through the hole. There is nothing complicated about this, the main thing is to do everything carefully so as not to damage the wire and glass of the camera lens.
	While the lens of a regular door peephole can be positioned as desired, then in the case of a camera it is important to align it properly. Do not forget about this so that later you do not find the image upside down on the display. Note! The red dot serves as a reference point, it denotes the upper part.
	The internal mounting block is assembled. For this, the threaded insert is inserted into the hole in the mounting frame. Everything is very simple, the most important thing is to choose the required insert, usually there are two of them in the delivery set: one is designed for thin door leaves, and the second for thick ones.
	The inner part of the structure is put in place. The order of work is as follows: First, the camera wire is pulled through the sleeve; On the back of the frame there is double-sided tape for tight fixation, the protective layer is removed from it, the structure is leveled and pressed against the surface; The sleeve is twisted, everything is like in a regular peephole: the outer part is held, and the inner part is wrapped clockwise.
	The system is being tested. To do this, the camera wire is connected to the connector on the back of the case, and the display is put in place. Advice! You do not need to fix anything, first make sure that the structure is level and all functions are working. If there are any problems, it is much easier to solve them now. If everything is in order, then you can proceed to the last stage.
	The fixing screws are screwed in at the bottom of the case. Everything is easy here: check if the holes match, and carefully screw in the fasteners. Note! Do not use too much force - you can rip off the threads in the plastic case.

How to assemble a door peephole?

A peephole is a necessary device that fits into a door and allows you to see who is on the staircase in front of your door before you open it. The quality of the view through the peephole depends on the viewing angle. Undoubtedly, the larger it is, the better the place is viewed. The object located in front of the peephole from the outside and the entire surveyed area as a whole will be distinct only in the presence of medium or bright illumination.

All manufacturers of door eyes have their own individual characteristics. Therefore, how to assemble the door peephole, see the attached instructions for the kit. Door peepholes differ depending on their intended purpose, that is, if you want to provide yourself with, say, external surveillance, then you should purchase secret eyes. For doors with a double layer, individual eyes are also designed, and bulletproof eyes and periscopes are installed to protect the owner.

The instructions provided by door installers will help you figure out how to install a peephole. In fact, the steps outlined in the instructions are not that difficult and not time consuming. The first thing to do is determine the level at which you will be installing the peephole. It will be determined by its frequent users, namely children and adults, that is, at what level and depending on their height a person can use it.

After you have marked with a pencil or pen the location of the eyelet, draw and cut out two templates. Glue them on 2 sides: outside and inside. Make sure the templates are parallel to each other. Take a drill, insert the drill, and punch a hole right down the center of the template.

Without putting the drill aside, make four marks on the template with a pencil and drill each of them strictly according to the template. Be careful with the length of the holes. It should be 5 mm, but no more. Before proceeding with the installation of the peephole in the hole, make sure that the outside of it fits into the holes made by the drill by disassembling the peephole. Also drill the holes required for the external and internal installation of the peephole. Clean the peephole by removing dust formed after working with a drill. Install the peephole.

Door peephole

The front door is an important and integral element of any home. It fences off the outside world from the private space of an apartment or house. The stronger and thicker it is, the more reliable the protection. But there are cases when it is necessary to find out what is happening behind the door without opening it. It is for such situations that a video door peephole is needed, which will help assess the situation and prevent uninvited guests from appearing on the doorstep.

What is a door peephole for?

Door eyes are important functional elements of any door, allowing one-sided inspection of the space outside the apartment (on the staircase), which does not require opening the doors. In addition, such an attribute will help prevent uninvited guests from visiting the house.

Important! Modern industry offers a fairly diverse range of door peephole options, some of which are equipped with video cameras and other security and control systems.

Design features

Regardless of the type of door peephole, its design has a standard set of elements:

A lens that enlarges the image and provides an external view;
Outer rail holding the lens;
Locks that firmly hold the lens;
Housing;
Internal nut;
Lens or eyepiece directed into the room;
Damper.

The number of lenses in different models and types can vary from 2 to 15 pieces.

Varieties

Door eyes have a large number of varieties, each of which has a special functionality and additional features. Most often, the following types of equipment are installed on the door:

A standard classic peephole installed on a metal or wooden door for more than a dozen years. Although this device makes it possible to see what is happening behind the door, it does not provide sufficient visibility. Only what is immediately in front of him is visible.
Panoramic door peephole. The lens of such a peephole has a structure divided into two lenses. This allows the lens to absorb a large luminous flux, making the image panoramic. In this case, it is not necessary to stand strictly close to the door or to the peephole. Everything can be seen from different viewing angles.
Hidden door peephole. Most often, it is disguised as nails included in the door trim, or other decorative elements. Such a device can be equipped with a camera, camouflaged from the outside, if the doors are a continuous sheet.
Bulletproof peephole. The name speaks for itself. This element is most often equipped with armored doors, which provide maximum protection against unauthorized entry.
Eyelets for double doors. Structurally, such an element consists of two parts and allows you to inspect the external space without opening them.
Periscope. Its peculiarity lies in the fact that the viewing lens and the eyepiece itself are located at different levels.

Attention! This option is especially relevant if the family has small children. The lens can be positioned at a level convenient for the child's growth.

Video-eye

In the production of door eyes, modern advanced technologies are also used, the use of which makes it possible to create practical and functional varieties, among which the video eye is especially popular.

Its design necessarily includes a video camera, microscopic in size, which is installed at one end of the door element. It transfers the image to a special monitor, and can show what is happening both in real time and in recording.

Depending on the type of device, information from the camera can be transmitted to the reader both using wired lines (cable), and via a radio channel, or via a WI-FI signal. By installing a video peephole on the door, you can be as calm as possible for your safety.

Electronic door peephole

This design also represents an experience in combining electronics and safety guards. Electronic door viewers are installed in place of the usual standard viewer. The external structure includes infrared illumination and light and bell sensors. An electronic part of the structure is installed on the inner side of the door, which is attached to a metal plate. On this element there is a screen that opens an overview of the staircase.

Attention! Unlike a video peephole, such a design is easy enough to install yourself, right in place of a standard peephole. There is no need to install wires and adjust the signal, and the unit itself is powered by standard AA batteries.

Selection and installation rules

Various types and price parameters complicate the process of choosing a door peephole. To buy high-quality and suitable equipment, you should pay attention to the following parameters:

Viewing angle. The peephole should be chosen according to this criterion depending on the space near the door. But modern optical devices used in eyes usually solve this problem at a normal level, providing an optimal viewing angle. In addition, the viewing lenses must clearly show the visitor's face.
Important! Almost all modern eyes provide a 180 degree viewing angle. But there are also specimens with a large parameter, reaching up to 200 degrees.
Door thickness. It can be of a standard type, elongated and exceeding 10 cm. Moreover, the body usually provides for an adjustment of its length for each type of product.
Light sensitivity. The ability of clear image transmission in low or dim lighting on the site depends on this parameter.
Width and diameter of the product. If the peephole is already installed immediately in the door, then this parameter is not essential, it is important to know it if it is necessary to replace it;
The material from which the peephole body is made. In most cases, the structure is made of metal or plastic. The metal element is more durable, practical and durable, and the plastic one has a lower cost, but a shorter service life;
The material from which the lenses are made. This can be plastic, glass, or optics used in the production of glasses. As a rule, the most expensive options are equipped with optical lenses, while the cheaper ones are equipped with plastic ones.

Usually, the choice is based on the budget and customer preferences, as well as the required functionality of the device.

Door eye latch

The latch is an important item that comes with most door viewers. It helps to increase passive safety and at the same time fulfills an aesthetic function by preventing light from outside. Sometimes, instead of a shutter, the manufacturer performs mirror-type spraying on the objective lens. It acts as a shutter, but may impair the quality of the view.

Installation features

No special skills or experience is required to install or replace a peephole, this can be done with a drill and masking tape required to drill the hole.

If the door peephole is not to be replaced, then you should remove the old one before buying a new mechanism, accurately measuring its external parameters. If the door has a solid structure and it was decided to install the peephole for the first time, then a hole of the required diameter should be drilled. To do this, a mark is made at the site of the future element for review, on which masking tape is attached. After that, a hole is drilled on both sides of the door. On the outside, a tip is installed on which the lens is located. From the inside, the recorder or lens is tightly fixed, which, if necessary, is twisted.

Attention! If you decide to install a video peephole, then it is better to entrust this work to experienced professionals who are familiar with the rules for setting up the signal transmission from the device to the monitor or laying the cable.

Reliable protection of a home is an important condition for living in it, and the presence of systems that prevent unwanted intrusions or uninvited guests contribute to the formation of a sense of security. A properly selected and well-installed peephole will help to reliably protect residents.

video peephole and other types, instructions on how to install, dimensions, video and photo

Do you think that installing a peephole is difficult? The accumulated experience allows me to assert that this work is within the power of even an inexperienced master. I will tell you how to choose high-quality equipment and give instructions with illustrations that will allow you to cope with the work, even for those who have never put a peephole in the door.

The main element of conventional eyes is a wide-angle fisheye lens, which provides a high-quality view of the space. Electronic variants use a camera.

To begin with, let's analyze what types of eyes are:

Illustration	Description
	Standard door peephole. This option is simple and consists of two parts - external and internal, which are twisted together. A lid may be present in the design to close the hole from light penetration.
	Panoramic door peephole. Its distinctive feature is a lens divided into two lenses. This design allows you to transmit more light flux. You don't have to stand close to see the image, you can be on the side of the structure.
	Double door system. It can be either standard or panoramic. The design consists of two parts, during installation, special accuracy must be observed so that the elements match.
	Bulletproof option. Used on bulletproof door leaves to ensure structural reliability. The installation method is no different from the usual version.
	Peephole periscope. This option is ideal for those with small children. You can watch both in the normal position and below, which is very convenient if you need to exclude the option of opening the door to strangers. The system is quite difficult to install, so most often the work is done by specialists.
	Electronic type video peephole. Previously, video options required adjusting the signal to transmit it to a monitor or TV. Modern technologies have made it possible to make a compact and simple option that anyone can easily install.

If you have decided on the type, it is worth understanding several criteria that are taken into account when choosing:

Viewing angle. The larger it is, the better you can see the space in front of the entrance. Cheap options have an angle of 120 degrees, more advanced ones - 180 degrees. The highest quality modifications have a view of over 200 degrees, which eliminates distortion along the edges of the image;

Door leaf thickness. There can be three options for products:

up to 60 mm;
up to 100 mm;
over 100 mm.

Any version of the eyelet is adjustable by 20-30 mm due to the thread. Some models are supplied with different sleeves so that you can find the best solution for your door;

Eye diameter. This indicator determines the size of the hole to be drilled. If in new designs you can choose any option, then when replacing old elements, it is easiest to choose products of the same size. Most often, the inner diameter is 20 mm;
Manufacturing material. Optics can be plastic or glass, the price of the first option is much lower, but the second is much stronger and more durable. The case can be made of plastic or metal, the second option is preferable, although it is more expensive.

I will tell you about two options for carrying out the work: the installation of a conventional peephole and the option with video surveillance.

Installation of a standard peephole

We will figure out how to install a peephole in a metal door.

Illustration	Stage description
	Measurements are being made. We are primarily interested in the thickness of the canvas, the other dimensions are not so important. Knowing the thickness, you can choose the right door peephole, rather than buying it at random.
	The instrument is being prepared. To do the work with your own hands, you need the following: Screwdriver with a drill for metal with a diameter of 5 mm; Pen drill with a diameter of 20 mm; Core drill for metal with a diameter of 20 mm; Construction tape. If the diameter of your eye is larger, then the feather and core drill are selected in accordance with the parameters of the product.
	The center of the door leaf is marked. The peephole is usually in the middle, so use a tape measure and pencil to mark the middle.
	The height of the location of the eye is noted. The standard option is 150 cm from floor level, but you can raise or lower the peephole so that it is as comfortable as possible to use it.
	Drilling is in progress. First of all, a through hole with a diameter of 5 mm must be drilled in a metal door. It is very important to use a drill bit long enough to protrude from the back of the door. When drilling, pay particular attention to the horizontal position of the screwdriver. If the hole is skewed, then the peephole will become crooked.
	A hole is drilled from the outside. A metal crown is inserted into a screwdriver or electric drill, with the help of which the hole expands to the diameter we require. It is important to work carefully so as not to damage the door leaf and not bend it.
	The lining is drilled from the inside. For work, a pen drill is used, the main thing is to keep the screwdriver evenly so as not to go to the side.
	The hole is cleared of debris and checked. Just look through it, if there are no distortions, then everything is done as it should.
	The peephole is fixed. To do this, it should be held from the outside and screwed from the inside. If the kit contains a key, then you can additionally clamp the knot from the inside.
	System operation is checked. Close the door and look through the peephole. This completes the installation.

Installing an electronic eye

Let's see how the camera is installed:

Illustration	Stage description
	This is what the camera kit looks like. It includes: Monitor with control buttons; Accumulator battery; Memory card; Camera; Fastening platform. You only need a screwdriver to work.
	The battery is inserted. If your system runs on batteries, then batteries are installed.
	A memory card is inserted. A special slot is provided for it, you will not confuse anything in any case.
	Remove the protective film between the power contacts. Usually there is a tongue on the outside, for which you need to pull and thereby remove the protection from the contacts.
	The sleeve is twisted from the camera. It will hold the element from the inside, so it is worth removing it in advance.
	The sleeve is inserted into the camera mounting platform. This completes the preparatory work.
	The platform with the sleeve is placed on the door leaf. For clarity, the work is shown on a transparent module imitating 70 mm thick doors. Naturally, before changing the system, you need to remove the old peephole. If you have a new door, then all the features of hole drilling are described above, the technology is suitable for this case as well.
	A camera is inserted from the outside. It is carefully wound into the hole, the train is pulled into the sleeve. After that, the sleeve is screwed up to the stop. There may be double-sided tape on the mounting plate and the camera for gluing to the door leaf, remove the protective layer from it before installing the elements.
	The camera cable is connected to the connector. The photo shows what the connection looks like in our case, but its configuration may differ for different equipment models.
	The camera is installed. It fits neatly with the connector and then snaps onto the plate.
	The camera is fixed with screws. For reliability, the body is fixed to the plate with two screws.
	The camera turns on. All the features of setting up the system will be prompted by the instruction. You can use the camera as needed, or you can configure the motion sensor, and the camera will always turn on when someone passes or stands in front of the door.

How to install a peephole in a metal door yourself

The realities of modern life are associated with constant concern for their own safety and the safety of those close to them. Despite the measures of protection of state law enforcement agencies, the risk of being attacked remains. Your own house or apartment is no exception. There is a widespread opinion: the thicker the door, the higher the safety of the apartment. But extraneous noises behind her, knocks, the sound of a doorbell require visual observation of what is happening, an assessment of the potential danger. It simplifies the solution of the issue by installing a door peephole, which will provide an adequate view of the staircase or yard area. If it is absent in the installed door, the owner only needs to choose the appropriate one by installing it himself.

Door with peephole

General information

The design of a classic doorbell includes a body (plastic or metal), two lenses (outer and outer), outer rails, decorative fastening nuts and a protective flap. The main role is given to the quality of the lens. Use plastic or optical glass. For plastic lenses, a low cost is characteristic, but the disadvantage is a short service life, clouding as a result of dust accumulation, provoked by a static magnetic field. Glass lenses have higher levels of transparency, clarity of perception of the visual image, the service life is characterized as significant, but the cost is an order of magnitude higher than plastic.

Peephole appearance

Selection of the door peephole

The stores offer a wide range of products for this purpose. To determine which one is necessary for the owner of the premises in each particular case, you can familiarize yourself with the types presented below:

standard simple, cheap to purchase, provide a simple overview of the territory;
panoramic, characterized by a wider and better view;
bulletproof;
hidden, placed in a decorative element, as a rule, equipped with a micro camera;

Hidden peephole

spaced, used in the presence of two doors, have two parts, viewing from the inner door, and the camera from the outer;
periscope type, with parts at different distances in the vertical or horizontal plane;
video peephole, installed with an additional alarm and image viewing unit, often provides for the function of opening the door using a magnetic lock device.

Eye angle

Factors accompanying its operation in optimal mode are also important when choosing a door peephole:

the angle of the visual view, while at least 180 degrees is considered optimal;
length of the lock structure - should ensure comfortable installation in the door leaf;
the constructive diameter of the eye, the larger, the better the light transmission of the image;
material.

Door peephole installation

Installing a peephole in a metal door will not be difficult for a person with an initial level of knowledge of plumbing and the ability to use a household electric tool. The order of work is as follows:

Alternative surveillance systems

Manufacturers, using modern technologies, are constantly updating the line of surveillance devices. Remarkable and worthy of attention is the installation of electronic systems that perform the functions, along with the main one, of fixing on the control unit of persons approaching the door of the room, a full recording of the picture of events taking place behind the front door, and many others, including an infrared image. But do not forget the fact that even in the case of installing a system with additional batteries, it ends up sometime, and simple optical door eyes do not need them.

Video surveillance system

How to properly install a door peephole in a metal door can be understood by watching the video material, while receiving recommendations and instructions from the master who has repeatedly carried out these works.

Installation of a peephole on an iron door

What kind of visual observation system to place on the entrance metal door depends on the degree of its security and the requirements that the owner of the premises makes for such an opportunity, while the financial security of the events seems to be an important component - the more complex the system, the more expensive the purchase.

Door peephole: varieties, device, principle of operation

Electronic type door peepers are considered to be a kind of novelty that has recently appeared on the modern market. If you use such equipment for the door, then you can make additional protection of the home due to the presence of special functional qualities.

Built-in peephole

The door leaf itself is a structure that not only performs a separation function for the room, but also protects it from the penetration of unwanted guests. Many people believe that if the thickness of the door leaf is greater, then it is stronger. This means that it will better protect the room. In some cases, apartment owners are required to know what is happening behind their installed door. Let's consider such cases:

Extraneous sounds are heard behind the door leaf;
Someone rings the doorbell and is silent after that.

A common method of reviewing what is happening behind the front door is to install a peephole. Door eyes were used as far back as the 60s of the last century. A peephole was invented for installation on the door by scientists from America named Robert Wood. Initially, the types of door eyes were primitive. The first of them was called "fisheye". Only with the passage of time, the door peephole device began to be used to equip doors in houses or apartments.

What does the device consist of?

Attention! Currently, door eyes are purchased without problems, since the assortment that is offered to the buyer is so wide that everyone will select a device according to their individual characteristics.

To better understand the device, consider its basic design:

A lens that is brought out;
External direction rail;
Elements with the help of which the main lens is fixed;
Fastening internal elements;
Inner lens;
Damper (it all depends on the configuration, this element is optional).

Flap option

The main aspects that pay attention to when choosing a door viewer are ordinary and panoramic

Inside its device, the panoramic door peephole has lenses in an amount of up to 15 pieces. The required amount depends directly on the body. But there are also individual factors that pay attention to in the selection process:

Viewing angle. Often this indicator should correspond to the area that is viewed with a peephole. In this way, maximum efficiency and safety are obtained. In addition, with the help of the lens, the face of the one who stands behind the door is clearly visible;
As for the preference for the optimal indicator, it is 180 degrees for viewing. Some manufacturers, in order to remove the small flaws that the 180 degree peephole has, made it 200 degrees. But there are not so many such models at the present time, so 180 degrees is still the optimal angle for viewing the entire area.

An essential factor when choosing a peephole for a door leaf is determining the width of the sash. If we consider the standard indicators, then there are three common options:

Standard type construction. This type is used for a door leaf with a standard thickness;
Extended version. Thickness is greater than the prescribed standard;
Long version. Such a peephole is installed if the door leaf is more than 10 centimeters thick.

Devices with standard parameters are becoming common. These types are used for solid or metal canvases. As for the adjustment, it is made using a special thread, which each eyelet has as standard.

Attention! If the door leaf is subsequently insulated, then the length of such a peephole will be small.

It is not enough to properly fix the equipment, you also need to take into account the width and diameter that the structure has. And all due to the fact that if the diameter and design do not match in parameters, then the visibility will be greatly distorted.
The material used in the manufacturing process becomes decisive in the installation and selection process. If you choose the wrong material for production, the design will not work for a long time. Most often, two main types of material are used for production: plastic or metal. As for the metal, it is, of course, durable and is not affected by external factors. If you pay attention to plastic, then over time it gives in to deformation or cracking. The material is destroyed and this can happen due to temperature changes;
The materials from which the viewing lenses are made also play a significant role in the full functioning of all equipment as a whole. Of course, the quality of such material also affects the cost of the peephole in its complete set. If we consider the materials that are used for such purposes, then the following are distinguished: plastic, ordinary glass, or optics, which are also used in the production of glasses.

Peephole made of plastic material

How to choose a door peephole? Main varieties and models

Panoramic option. The first aspect by which this option is distinguished from the rest is that the device is equipped with two lenses. With this design, the lens has the ability to receive a large number of light fluxes and then a panoramic image is supplied. To view the image, it is not necessary to be in front of the eye or close to it;

Panoramic view

Bulletproof peephole. The functional actions of the device are clear from the name. That is, such a structure can be assembled for those canvases that need additional protection. Such a peephole is installed to obtain the highest degree of security;
Secret type. More often this option is disguised as nails that are in the finishing material of the canvas. Often this variant is a kind of micro type camera. That is, the outside is a reader, and on the inside is a recording;
The type used for a double door leaf. With the help of this type, they look through the site without opening the inner door. The design is based on two main parts;
Periscopic peephole. This type of equipment has a lens and an eyepiece at different levels. Most often, such a device is used in a room where there are small children due to the fact that it is possible to place parts of the complete set at a level that is convenient for viewing.

Periscopic type

Door peephole installation

To install such protective equipment, you do not need to have any special skills. If a peephole is already installed in the door and it should be replaced, then initially deal with the question: how can you remove the old peephole from the door? It's simple - the structure is removed from the hole. If there is no hole, then it is pre-drilled in the canvas.

Before drilling the hole, select a location where the device will be located. Make a mark on this place with construction tape;
After that, on one and the other side, make holes of the required diameter;
On the outside, place the tip on which the lens is located, and on the inside, the "recorder" is mounted.

Positive and negative qualities that a door peephole has

With the help of equipment of this type, without opening the door leaf, the platform is visible, which is located behind the closed door;
A wide range of devices with which to select any individual option.

If we consider all of the above, then we can say that the door peephole was and is a universal device with which additional protection of the room is carried out. Check out our video for a detailed overview.

Door eyes

Requirements for door peepholes

The simple device of the door peephole allows, without opening the front door, to see the space of the staircase. And, although the front door itself is capable of protecting the house from intruders, it is always good to see who is behind the door and knocking on your house.

That is why the door peephole should give a clear and maximally complete image of objects located at a distance of 0.5 to 5.0 meters in front of the door in conditions of medium and bright illumination. Today there are special door peepholes that can provide a view of the space even through double doors.

There are also models (the so-called - secret eyes), which make it possible to guarantee secrecy observation. In addition, periscopes and bulletproof eyes are currently being produced, which guarantee protection to the owners of the house during observation. Often, door peepholes duplicate television surveillance systems, which also increases the overall protection of the home.

In this case, it is very important to make the right choice of the door peephole. But first, let's figure out what the usual door peephole device is.

Door eye device

Although the design of the door peephole can be very diverse, the overall structure, as the experience of recent decades shows, is approximately always the same. So, all door eyes consist of an eyepiece (a lens facing the observer's eye) and a lens (a lens facing the observed object).

In this case, the door peephole design implies that other lenses can be placed between the objective and the eyepiece. The mechanical design of most of the eyes includes an outer nut body and an inner nut. It was noticed that the total number of lenses in the eyes ranges from 2 to 15 pieces.

Mirror systems are used in special-purpose door eyes (such as periscopes). The most common device for door peepholes today is the design of the optical system, which consists of four lenses, which provide a viewing angle of approximately 180 without significant image distortion.

Also, the device of almost any door peephole today includes the so-called flaps. Currently, only the cheapest products of this class of goods are produced without this component. The role of the shutter is quite large: it does not let light through from the apartment and allows the owner of the apartment to secretly approach the peephole and, without revealing himself, monitor the site.

The main requirements for the design of the damper are that it must close the opening of the peephole, quietly and easily open and close, and during its movement, due to the absence of sharp corners, it must not come into contact with the door or its upholstery.

Choosing a door peephole

When choosing a door peephole, it is better to immediately find out which viewing angle of the peephole suits you best. You also need to immediately determine the diameter of the eye. If, for example, the diameter of the hole in the door of your house is greater than the purchased peephole, then there will be only one way out - to return to the store and change the peephole to a model with a larger diameter.

Since the main characteristic of a door peephole is the viewing angle, then, naturally, the larger it is, the better. The widest angle of view is 180 °: with this eyepiece, even the rug lying under the door is clearly visible. The smallest tilt angle is considered to be an angle of about 120 °.

In addition to the required viewing angle and the diameter of the eye, at the stage of choosing a model, you need to decide on the thickness of the door: this indicator is also very important. For ordinary doors, the thickness, as a rule, varies from 35 to 60 mm, for good, reinforced doors, it can be up to 85 mm.

Based on these parameters, the "bodies" of the door peepers can be very different in length and very different in diameter, so that you can choose a peephole for any door. In addition, the peephole device includes a thread that adjusts the length of the model. According to this parameter, all eyes can be divided into three main groups: standard eyes for doors with a thickness of 30-55 mm, elongated eyes for doors with a thickness of 55-100 mm and extra-long eyes for doors with a thickness of more than 100 mm.

According to their material of manufacture, the optics of the door peephole can be plastic or glass. It is believed that glass models are more durable, as the glass is scratched less. It is customary to make the "body" of the door peephole from metal or plastic. Therefore, when choosing a door peephole, pay attention to the material from which the model is made, as this affects the quality of the device and its price. Experts note that glass and metal eyes are the most reliable, but at the same time the most expensive.

The appearance of the product depends to a greater extent on the quality and type of coating of the peephole: it is necessary that it harmoniously fit into the overall design of the entrance door. However, it has been observed that often a peephole made of ferrous metal with a coating looks better than a peephole made of non-ferrous metal, but uncoated. It should also be noted that door eyes made of brass with imitation "gold" can darken over time, and eyes made of chrome and titanium coated steel are practically not subject to scratches and do not darken.

Let your choice of door viewers, taking into account our advice, be correct.

What is a door peephole for?

Important! Modern industry offers a fairly diverse range of door peephole options, some of which are equipped with video cameras and other security and control systems.

Design features

Regardless of the type of door peephole, its design has a standard set of elements:

A lens that enlarges the image and provides an external view;
Outer rail holding the lens;
Locks that firmly hold the lens;
Housing;
Internal nut;
Lens or eyepiece directed into the room;
Damper.

The number of lenses in different models and types can vary from 2 to 15 pieces.

Varieties

Door eyes have a large number of varieties, each of which has a special functionality and additional features. Most often, the following types of equipment are installed on the door:

A standard classic peephole installed on a metal or wooden door for more than a dozen years. Although this device makes it possible to see what is happening behind the door, it does not provide sufficient visibility. Only what is immediately in front of him is visible.
Panoramic door peephole. The lens of such a peephole has a structure divided into two lenses. This allows the lens to absorb a large luminous flux, making the image panoramic. In this case, it is not necessary to stand strictly close to the door or to the peephole. Everything can be seen from different viewing angles.
Hidden door peephole. Most often, it is disguised as nails included in the door trim, or other decorative elements. Such a device can be equipped with a camera, camouflaged from the outside, if the doors are a continuous sheet.
Bulletproof peephole. The name speaks for itself. This element is most often equipped with armored doors, which provide maximum protection against unauthorized entry.
Eyelets for double doors... Structurally, such an element consists of two parts and allows you to inspect the external space without opening them.
Periscope. Its peculiarity lies in the fact that the viewing lens and the eyepiece itself are located at different levels.

Attention! This option is especially relevant if the family has small children. The lens can be positioned at a level convenient for the child's growth.

Selection and installation rules

Various types and price parameters complicate the process of choosing a door peephole. To buy high-quality and suitable equipment, you should pay attention to the following parameters:

Viewing angle. The peephole should be chosen according to this criterion depending on the space near the door. But modern optical devices used in eyes usually solve this problem at a normal level, providing an optimal viewing angle. In addition, the viewing lenses must clearly show the visitor's face.
Important! Almost all modern eyes provide a 180 degree viewing angle. But there are also specimens with a large parameter, reaching up to 200 degrees.
Door thickness. It can be of a standard type, elongated and exceeding 10 cm. Moreover, the body usually provides for an adjustment of its length for each type of product.
Light sensitivity. The ability of clear image transmission in low or dim lighting on the site depends on this parameter.
Width and diameter of the product. If the peephole is already installed immediately in the door, then this parameter is not essential, it is important to know it if it is necessary to replace it;
The material from which the peephole body is made. In most cases, the structure is made of metal or plastic. The metal element is more durable, practical and durable, and the plastic one has a lower cost, but a shorter service life;
The material from which the lenses are made. This can be plastic, glass, or optics used in the production of glasses. As a rule, the most expensive options are equipped with optical lenses, while the cheaper ones are equipped with plastic ones.

Usually, the choice is based on the budget and customer preferences, as well as the required functionality of the device.
