How to assemble a peephole. The main types of door eyes. Door installation

The front door is a means that separates the personal space inside the house from the outside world. The thicker and stronger the door, the more reliable its protection. However, often the inhabitants of the house simply need to find out what is happening behind the door, for example, if someone calls or any extraneous sounds are heard behind it. by the most in a simple way to control the situation is to install a peephole door. In the article, we will consider the types door locks and how to install them.

The modern peephole became widespread only in the 1960s. Its founding father is considered to be the American scientist, writer and inventor Robert Wood, who invented the wide-angle fisheye lens back in 1906.

However, it took quite a long time before his invention received well-deserved fame, distribution and application in everyday life.

Today you can buy door eyes different not only in shape and size, but also in functionality.

Door peephole design

The standard peephole design consists of:

• a lens directed at an external object (lens);
• outer rail;
• clamps on the sides of the lens;
• eye body;
• inner nut;
• lens directed inward (eyepiece);
• damper.

Depending on the length of the peephole body, from 2 to 15 lenses can be located in it.

How to choose a peephole?

There are several main factors to consider when choosing a peephole.

The first and most important factor is the viewing angle.. The higher this indicator, the higher the level of security, because not only the person’s face at the door will be visible, but also the space below and on the sides, which is very useful in the modern, unfortunately, too criminal world.

• The optimal viewing angle is 180 °, although manufacturers often make the angle a little more than 200 °, in order to remove distortion along the viewing boundaries, the same 180 ° will eventually remain the working spectrum.
• Another trick that manufacturers use to increase the viewing angle is to move the focus of the lens forward. This design provides a greater overview of space.

The next factor determining the choice of peephole is the width of the door.. Depending on this, one of the eye options is selected:

• standard (if the door is 30 to 55 mm thick);
• elongated (if the door is 55 to 100 mm thick);
• long (if the door is more than 100 mm thick).

The most common are the eyes of a standard size, they are suitable for any modern metal or wooden doors. Width adjustment is made using a thread that is on any eye. However, if the door will be insulated from the outside or from the inside, the usual length of the eye may not be enough.

Tip: when buying an elongated or extra long eyelet, it is important to pay attention to its optical characteristics, which should differ from the standard version. Unfortunately, many manufacturers, in order to reduce the cost final product, simply complete the standard peephole with a long rear nut, without changing the optical characteristics. These actions are fraught with a decrease in the viewing angle, as well as poor visibility of objects.

• In addition to the width of the door itself, it is important to consider the width of the peephole diameter. The larger it is, the higher the aperture ratio of the lenses installed in it. High luminosity allows you to see objects more clearly, while it is not necessary to come close to the peephole, the external space will be clearly visible from a distance of 5-7 cm from the peephole, while maintaining a wide viewing angle.
• The only additional comment to the wide diameter is that in the future it will no longer be possible to replace it with a narrower one, because. the hole for it is correspondingly wider than the standard one.

The material from which the peephole is made, is, perhaps, decisive in the final price of the product. There are two main materials for eyelet housings: metal and plastic. Metal is more durable and resistant to external influences, plastic can be deformed or cracked, for example, due to temperature changes.

Lens materials are also different - plastic, ordinary glass or spectacle optics.

• The main disadvantage of plastic optics is its fragility. Over time, it tends to become cloudy and deformed. In addition, plastic accumulates static electricity and attracts dust. All these factors lead to an early, already in the second or third year of operation, loss of image clarity.
• Glass does not have such problems, but it is more fragile compared to spectacle optics. The only disadvantage of glass optics is its higher price compared to plastic. Although, strength and durability will more than pay for the costs.

Latch on the door peephole

The latch has become an integral element of the peephole, it performs both a passive safety function - so that it is not visible from the outside whether someone is in the house or not, and an aesthetic function - light from the outside does not penetrate into the room.

• It also allows the observer to freely approach the door and choose whether to open it to people outside. There is always someone who simply does not want to open the door, without any objective safety factors or good manners.
• Sometimes the role of the valve is performed by mirror coating of the objective lens. It is quite popular because it does not require additional internal elements peephole, however, the reduced brightness of the image can be called a minus.

Door peephole installation

Installation is quite simple and does not require special skills. If the door does not have a special hole for the peephole, it must be drilled.

• For this, a place is selected on the door where it will be located, glued masking tape and markup is done.
• Then a hole of the required diameter is drilled on both sides of the door.
• A tip with a lens is inserted from the outside of the door and with inside screwed tightly into the viewfinder.

Types of door eyes

• Panoramic eye. His hallmark is a lens divided into two lenses. Thanks to this design, the lens receives a greater light flux and gives a panoramic image to see which does not have to stand directly opposite and close to the eye.
• Bulletproof eye. The functionality is in the name, it provides increased security.
• Secret eye. It is usually disguised as nails in the door trim. As a rule, this is a construction of a microvideo camera on outer door and receiving device inside.
• peephole for double door, allows you to view the space without opening the inner door. Has two components.
• Peephole-periscope. In this type of eye, the lens and the eyepiece are at different levels. This type is very popular with families with children, as it allows you to arrange the components so that the eyepieces are both at a level convenient for an adult and at a child's height.

Video-eye

It is worth dwelling on this type of eye in more detail, since this model is gaining more and more popularity from year to year, which is not surprising in the era of technological progress.

The principle of operation of the door peephole with a camera

At one end, a video camera is installed, usually small or micro-sized, built into the door. It transmits the image to the receiving monitor. The picture can be transmitted both constantly, in real time, and on demand.

What is important to consider when choosing a video eye?

• As in the case of a conventional peephole, the viewing angle is paramount. Thanks to technical solutions and telescopic attachments, in most cases this issue is perfectly resolved, and video eyes provide an excellent full review area in front of the door.
• Others no less an important factor is the sensitivity of the eye to light. The higher it is, the better the eye "sees" in poor lighting. You can clarify this point in the technical characteristics of the camera built into the door surface.
• According to their device, video eyes are divided into case and frameless. The former are more reliable and durable, while the latter are cheaper and easier to install.
• Video surveillance can be organized according to one of the two following schemes:
  1. the signal is broadcast over a radio channel in the UHF range, using a television signal transmitter to receive it on a TV.
  2. the image is transmitted via cable directly to the low-frequency output of the monitor or TV.

• It is better to entrust the installation of a video eye to professionals, since certain knowledge and skills will be required to set up the signal. Also, you may need to work on laying the cable in the apartment.
• If there is a desire or need, in addition to video surveillance, to be able to observe through a standard peephole, it is worth considering installing a hidden camera with a lens. Of the pluses, it is worth noting the round-the-clock recording of the territory in front of the door and the opportunity, if necessary, to view this material.

Electronic wireless door peephole

The electronic eye is a variation of the video eye, in that the image is also transmitted to the monitor and there is no direct observation through the eyepiece.

However, there are significant differences:

• The electronic peephole consists of a doorbell and a video camera that are mounted on the outside of the door, as well as an LCD display for the inside. When you press the call button, the device activates the liquid crystal display, takes a photo and starts video recording. The device is equipped with a slot for memory cards, in the settings you can change the parameters of photo and video recording.
• An electronic peephole allows you to see what is happening outside at any time, for this you need to activate the LCD display with a touch and select the appropriate menu section. It can conduct video recording even in low or no light, for this you need to select the use of infrared illumination in the settings.
• Unlike video peepholes, the installation of an electronic peephole is simply elementary, the place where a standard peephole was previously installed is used as a hole, no additional work drilling is not required. No wires or other connections are needed. This device runs on batteries. And its cost is relatively low.

As a completion. The most important thing in a room is its comfort and safety, modern door eyes are able to meet the highest requirements of consumers, but no matter how good it is, and no matter how strong the door on which it is located, the common sense and caution of the residents remain the main factor.

The realities of modern life are associated with constant concern for one's own safety and the safety of the close environment. Despite measures taken to protect state law enforcement agencies, the risk of being attacked remains. no exception and own house or an apartment. There is a common opinion: the thicker the door, the higher the security of the apartment. But extraneous noises behind it, knocks, the sound of a doorbell require visual observation of what is happening, an assessment of the potential danger. The installation of a door peephole simplifies the solution of the issue, which will provide a sufficient overview of the staircase or yard area. In his absence in installed door the owner just needs to choose the right one by installing it himself.

General information

The design of a classic doorbell includes a body (plastic or metal), two lenses (outer and outer), outer rails, a decorative fastening nut and a protective flap. The main role is assigned to the quality of the lens. Use plastic or optical glass. Plastic lenses are characterized by low cost, but the disadvantage is a short service life, clouding as a result of dust accumulation provoked by static magnetic field. Glass lenses have higher rates 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 ones.

Door peephole selection

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 decor element, usually 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, while the parts are at different distances in the vertical or horizontal plane;
• video peephole, installed with an additional alarm and image viewing unit, the function of opening the door using a magnetic locking device is often provided.

eye angle

Important when choosing a door peephole are the factors that accompany its operation in the optimal mode:

• visual viewing angle, while at least 180 degrees is considered optimal;
• the length of the lock structure - should ensure comfortable installation in the front 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 plumbing knowledge and the ability to use household appliances. electric tool. The order of work is as follows:

Alternative Surveillance Systems

Manufacturers, using modern technologies, constantly update the line of surveillance devices. Notable 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-fledged recording of the picture of events occurring outside the front door and many others, including infrared image. But do not forget the fact that even in the case of installing a system with additional batteries, it once ends, and simple optical door eyes do not need them.

Video surveillance system

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

Mounting a peephole on an iron door

Which visual surveillance 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 is also an important component - what harder system the more expensive the purchase.

Comments

Unfortunately, there are no comments or reviews yet, but you can leave your own ...

In order to protect your house or apartment from strangers and unwanted guests, only a solid door and a reliable lock are not enough. For maximum security, you also need to see who you will open the door to. The simplest and accessible way this to ensure is the installation of a peephole. On sale there is a wide variety of such devices that can satisfy any needs of buyers.

What are door eyes

Despite the abundance of models and the desire of manufacturers to equip their products with new useful features, the device and purpose of the peephole remain the same: it is inserted into a through hole in the canvas and allows you to see the face of a person standing outside.

Design features

The door peephole consists of several parts:

Pros and cons of peepholes

The peephole is useful device, which has a number of advantages:

• provides an opportunity to see everything that happens in front of the front door;
• easy to install, even a beginner can cope with this task;
• if a video camera is built into the peephole, it allows you to inspect the area even in the absence of lighting, while many models can record and save an image;
• has an affordable price. Even a video eye, which costs more than simple optical models, is still cheaper than an intercom.

Among the shortcomings door peepholes need to mark:

• both optical and video eyes can be sealed or closed, then the visitor cannot be seen;
• there is no way to talk to the visitor.

The latch is an important, but optional element of the peephole, it may be absent on many models. Performs two functions:

• hides the peephole on the inside of the door;
• does not allow an outsider to look inside, does not let light into the apartment and from it to the entrance or to the street.

Some manufacturers use a mirror coating on the lens instead of a shutter. It solves the same problems, but degrades the quality and brightness of the image.

The latch closes the peephole from the inside and provides additional security

Types of door eyes

To decide on the choice of a door peephole, you need to know what types of these products exist, their features and differences.

Panoramic

A feature of panoramic models of door eyes is that their lens is divided into two halves. This solution allows you to increase the horizontal viewing angle, so the observing person does not have to be in front of the eyepiece. You can see what is happening behind the door, being at a distance of up to 1.5 meters from the peephole.

periscope

The difference between periscope models is that their eyepiece and lens are at different heights. To transmit the image, a system of mirrors installed inside the periscope eye is used.

The periscope peephole is convenient to use in families with small children. The eyepiece, located at the bottom of the canvas, will allow the child to have a good look at the adult for whom he will open the door. The disadvantage of this model is that for its installation it is necessary to disassemble the door leaf.

At the periscope eye, the eyepiece and lens are located at different heights

For double door

This solution is convenient to use in case of installation of a tambour door in a house or apartment. It consists of a double peephole in two parts, which are installed in both doors and are located opposite each other. Thus, you can see everything that happens in front of the door without opening the inner canvas. Please note that as the distance between the doors increases, the image quality will deteriorate. The best option would be when there are about 2-3 cm between them.

The peephole for the double door allows you to see the visitor without opening the inner leaf

Video-eye

The operation of the video eye is similar to the principle of the video intercom, but in this case there is only an image and there is no way to talk with the visitor. This solution can be used both in an apartment and in a private house. To obtain a high-quality image in the dark, infrared illumination is installed on most models.

The video eye can be connected to a computer, TV or any other equipment that can display an image. The signal transmission from the camera to the screen can be performed in the following way:

Video: analog wired video peephole

Electronic or digital

One of the most modern options is an electronic peephole. Its difference from the video eye is that the set already has a small monitor. It is installed on the door from the inside. Outside there is a button, a light sensor and an infrared light. They are located on a plate that is fixed from the inside. With the help of a loop, the outer and inner parts of the bell are connected into a single mechanism.

The digital peephole consists of a lens and a monitor connected by a cable

After pressing the call button, an image appears on the screen. The device runs on batteries, so when installing it, there are no difficulties with connecting to the network. Digital video eyes have built-in memory, the volume of which is different models may differ.

Hidden

The peculiarity of the secret eye is that it is almost invisible on the surface of the door leaf. It can imitate a screw head or one of the elements of door fittings. Such a peephole can be placed not only on the canvas, but also on door frame Or even close to the door.

Free sale of hidden door peepholes is prohibited. If you managed to purchase such a model somewhere and you want to install it, then you will have to hang a warning next to it that covert surveillance is underway. Usually secret eyes are used by special services. The main disadvantage of such models is that they usually have a limited viewing angle.

A hidden peephole provides a viewing angle of about 100 degrees with a minimum hole diameter on the outer side of the door of 0.7 ± 1 mm

With motion sensor

This is one of the varieties of video or digital peepholes. The peculiarity of such devices is that they automatically turn on the recording when there is movement in front of the front door. This is a handy feature when you are not at home. After reviewing the recording, you can see who came to your door.

Vandal resistant and bulletproof

If there is a risk of intruders entering your home that can ruin the peephole, it is better to purchase an anti-vandal model. The lens in such eyes is made of durable glass, and if a video camera is built into the device, then it is securely hidden inside. The viewing angle in anti-vandal products is small - usually about 75 o, the light sensitivity is also lower than that of standard eyes.

There are also bulletproof models that have extra strong lenses. It makes sense to mount them only in armored doors. Most often they are installed at the entrances to banks, financial institutions, but can also be used on the door to a house or apartment.

Bulletproof peephole has extra strong lenses

Features of choice

To do right choice door peephole, you need to pay attention to the following characteristics:

1. Viewing angle. This parameter shows what space can be viewed through a particular peephole. The optimal indicator considered a viewing angle of 180 o. Some manufacturers produce models in which it reaches 200 o, but this rarely makes any practical sense.

   Optimal Angle peephole view is 180 degrees

2. door thickness. The choice of the length of the door peephole depends on its size. There are several types of eyes and each of them has the ability to adjust the length in a certain range:
   • standard - used for doors whose thickness is from 35 to 55 mm;

     Standard eyelet length 35–55 mm

   • elongated - 55–100 mm;

     Eyelet length 55–100 mm

   • extra long - more than 100 mm.

     The length of the extra long eye is more than 100 mm

3. Light sensitivity. It characterizes how clear the picture will be with an insufficient level of illumination in front of the front door. Light sensitivity is measured in lux and for modern devices it is usually tenths or hundredths of a lux. The smaller this parameter, the better it will be possible to see visitors in the dark. If there is always lighting behind your door, the light sensitivity of the eye is not so important, but if it is not there or it disappears periodically, it is better to take a model with a minimum value of this indicator or with IR illumination (only for video eyes).
4. Diameter. It is important when the eye is being replaced. It is important to choose a product that will fit into the existing hole tightly and without gaps.
5. Body material. Most often, these devices are made of plastic or metal. plastic models have a lower price, but they also have a short service life. Metal products are characterized by high strength and durability, and their cost is much higher.
6. lens material. These peephole elements can be made of glass or plastic. In more expensive and high-quality models, glass optics are installed, and in cheap ones, plastic ones.

One of the most common mistakes made when choosing a peephole is buying products with plastic lenses. They scratch very quickly, so after 2-3 years of operation, the image quality deteriorates greatly. The best option is a device that has at least 4 glass lenses. Such a solution, due to the gradual refraction of light, makes it possible to obtain an image of normal quality.

Door peephole installation

Despite the fact that there are different types door eyes, the technology of their installation is almost the same. It also does not matter if you insert it into a steel or wooden door. The difference will be only in the efforts made, since it is much easier to work with wood than with metal.

To install the door peephole, you will need the following tools:

Installation sequence:

1. Markup. The height at which the door peephole should be installed is not specified by the standards. Choose it in such a way that it is convenient to use this device for all family members. At eye level, glue on the door leaf masking tape and mark on it the place of installation of the peephole. It is necessary in order not to damage the door leaf during installation work.

   Unscrew the thread and disassemble the eye into two parts

2. Create a hole. Using a caliper, measure the part of the eye with internal thread because its diameter is larger. Take a drill, the diameter of which is 0.5 mm larger than the resulting size. Make a hole so that the drill only appears from the back. After that, continue to drill from the other side of the canvas. This is necessary so that chips do not appear on the wooden surface.

   When creating a hole, the drill must be located perpendicular to the door leaf

3. Install the peephole. From the outside of the door, a part with an external thread is inserted, in which the lens is located, from the inside - a part with an eyepiece. Holding the outer part of the peephole, twist the element, which is inserted from the side of the apartment, until it stops. It has slots on it. Using a wide screwdriver or plate right size well tighten both parts of the device. To ensure a tight connection of both parts of the peephole, a screwdriver must be inserted into both slots at the same time.

   Both parts are inserted from different sides of the door and twisted together

Dismantling and replacing the peephole

Sometimes there are situations when vandals damaged the lens of the device or the lenses failed due to their poor quality. In this case, it is necessary to dismantle the old door peephole and install a new one. There is nothing difficult in this and everything can also be done by hand.

The work is performed in the following sequence:

If the glass lens is scratched, then in this case it is not always necessary to replace the door peephole. You can buy a glass polishing paste such as Xerapol or similar. It is enough to squeeze a little paste onto the lens and polish it with a rag.

The peephole is a part of the front door, without which we have not imagined 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 inside or not. Modern models of the door peephole do allow you to monitor what is happening on landing remotely, from the office or while on vacation. The market provides a huge selection, so you can find something to your liking, requests and wallet.

How is the door peephole

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

The fisheye is also an integral part of the classic door peephole. It is designed to enlarge the image, so people appear much larger through the peephole. Lenses are also placed in the case, 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 quickly fails, 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 door eyes are equipped with armor-piercing glass lenses.

The size of the device varies from the thickness of the door leaf. metal sheet thinner than wood, but modern doors practice layering, so steel door may be thicker than old wood. There are door eyes of the following size:

• 30-55 mm. This is the thickness of a standard front door;
• 55-100 mm. Paneled doors or decorative elements;
• Over 100 mm. Armored doors, which are more often used at protected facilities, in warehouses for especially valuable goods.

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

When choosing a peephole Special attention give the class to the door itself.

Door peephole: types

Standard. The eyepiece and lens form a single line, and are located opposite each other. The simplest and most affordable version of the peephole. 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 body - they will last longer.

Periscopic. Represents more complex structure. There are two eyepieces on the inside, and a lens on the outside. The image is transmitted to the second eyepiece using mirror lenses. Why is such a design needed? For convenient use by residents of different heights. If there is a child in the family and you are afraid to leave him alone because 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 on top or at the ends. Outside, no one will guess that a resident of the house can watch him.

Panoramic. The large eyepiece, the 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 see the entire landing.

Electronic peephole with video camera. The most modern type of door peephole. It has the function of video shooting, 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.

Installing a peephole in a metal door

The principle of installing a door 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 peephole model. Furthermore, metal doors are often supplemented inner lining from MDF and decorative elements, which somewhat complicates the task.

Stages of mounting a viewing device in a metal door:

1. Using chalk or pencil, mark the location of the future eye. Consider the height of all family members and choose the average.
2. To avoid deformation interior decoration door or its coverings, stick a film or tape on the drilling site.
3. Measure the diameter of the eyelet body. If the part has an internal thread, use a drill wider than the result obtained by half a millimeter.
4. You need to drill from the inside, directing the drill towards the outside of the door.
5. Do not drill through the door. Get to the outer layer exterior finish and stop. Then drill from the outside. This little trick helps to avoid the formation of nicks, chips and bumps.
6. A lens is installed from the outside. From the inside, respectively, the eyepiece.
7. Connect both parts of the eye with screwing movements.

Electronic door peephole: types, advantages, installation

A video peephole is a complex type of device that makes life safer. Unlike classic analogues, 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:

1. Wireless with color recording function. Installed like a normal peephole. In terms of image quality, it is inferior to monochrome and costs more. But it has the function of video recording in color.
2. Monochrome, infrared. Easy installation, IR illumination, convenient operation. Monochrome peephole will be a worthy alternative to the usual.
3. Electronic black-and-white peephole complete with a matrix camera. Difficult installation, image distortion, small monitor. Of the benefits - an affordable price.

Advantages

Despite the complexity of 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 an image on a monitor. This is convenient for those who do not like to squint and close one eye. From a comfortable distance you can see the panorama of the staircase.
• 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 reverent about security. You may be on the other side of the world, but know exactly what is happening in your entrance and who is coming to the front door of the apartment. How it works? The peephole is connected to a computer or other device for the purpose of storing data. Also in each model with a recording function there is a slot for a microSD card.
• Built-in motion sensors. An additional bonus in the piggy bank of the security system. Even in the dark, you will know that there is someone next to the door. The system is adaptive both for residential buildings and for office space and warehouses. It is an excellent addition to the main room alarm system.
• You don't need to get a license. Classic video surveillance systems are subject to mandatory licensing in some 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 the front door. In most cases, adapter rings are included in the video peephole 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 is fine. In some cases, you will have to increase the diameter. You can do this with a perforator. To do this, select a nozzle desired diameter and drill in turn on each side, without going through. This will help to avoid external defects in the door leaf.

Next, install the camera in the hole and fix the monitor. Usually, the kit includes special bolts that are 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, and it is better to contact a specialist.

There are also models that work from the network. Additional manipulations are performed with them in order to connect and mask the wire. Such devices are not recommended to be installed independently.

Connecting a video eye: video

The choice of complexity, price and type of 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. Guardian metal doors 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.

Why call the master, if you can embed the peephole yourself.
This is the opinion of the majority of those who have ever held a metalwork or carpentry tool in their hands, but not as a specialist, but as an amateur.
If someone has ever had to deal with this issue, he will definitely say that let everyone mind their own business.

How easy or difficult it is to embed a peephole in the door if there is no experience.

To begin with, let's figure it out and clarify which door and what material it is made of.
If the door is wooden, then this is one thing, and if it is metal, then this is completely different.
At first glance, it may seem that it is more difficult to embed a peephole into a metal door. But here it could just be the other way around.

Difficulty peephole peephole in a metal door may lie only in the strength of the metal, and everything else, most likely, will go like clockwork.
Yes, drilling a hole in thick iron is not easy, but who said that the door is made of thick steel.
As a rule, ordinary entrance doors are made of metal with a thickness of no more than 2 mm.
Making a hole under the eye in such a thickness is not a serious obstacle for a person armed with a modern tool.

There is one small but very important nuance.
Drilling a hole in metal without experience is extremely dangerous for both the door itself and the master.
At the exit, the drill may jam and break, resulting in serious injury or injury.
Metal rupture can also occur and instead of a neat hole
the hole will be like a daisy.

It will not be superfluous to add and warn if the door has a decorative finish.
If all the necessary peepholes are not observed when inserting finishing material may suffer, and then the cost of facing will be added.
In a word, for such an insignificant procedure as a sidebar, it is worth preparing thoroughly, and if there is the slightest doubt about the positive completion of this issue, it is better not to take up the job.

One of the cheapest, but quite reliable ways to protect against intruders is a door to door.

The built-in eyepiece allows you to see what happens when boarding, to "identify" your visitors and, if necessary, to view documents that are presented without opening the door.

These products are very wide in the market. There are very cheap and very expensive models. Let's try to figure out what makes them different and whether it makes sense to pay more.

The first products of this kind that appeared in our country could not provide complete security.

The attackers have learned to simply "deceive" them. To avoid looking, it was enough to press against the wall by the door or sit on the threshold. This feature is a result of the low viewing angle of cheap products.
Experts recommend mounting eyes, which looks like 180-220 degrees. It's better, it's better. You also need to consider the fact that the edges of an image are almost always blurry.

How to install pefoles in metal doors

It looks like some areas come into view, but what happens there is next to impossible.

Maximum visible angle without blur panoramic eyes. This is because the lens of the product consists of two lenses - left and right. Plus, you don't have to get to the door and click on your eyes to get a shot.

The distance at which interrogation is possible depends on the model and can vary from one step to one and a half steps.

Before buying and trimming the case through the door, you need to understand what features to consider when choosing.
From the point of view that he has already defined, we are now talking about materials.

The body of the product can be made of plastic or metal. The first is cheaper, but not very strong.

Metal models are much more reliable.
Lenses are the main part of the product. Their quality and quantity depend on the clarity of the image. They can be made from plastic, regular spectacles or spectacles.
The first is the cheapest, the last is the most expensive. Plastic lenses initially provide light output.

In addition, they are able to accumulate static electricity, which attracts dust particles. And the material itself eventually becomes destructive and loses its transparency. In a word, after a few years, the images transmitted by such lenses become blurry and unclear.
More Recommended bind with ordinary glass lenses.

And the best option is products from special eyewear glasses. Fully transmits the luminous flux and is characterized by increased power.

Of course, these models are the most expensive.

But they will serve regularly for many years.

Shielded eyes may be used for objects requiring serious precautions. Inside such products is a layer of transparent glass-tight glass. This does not affect the image quality in any way and can be kept in focus with a short firearm (pistol).

And the last factor that can affect the choice is the length of the eyelids.

Standard models are designed for doors with a thickness of 35-50 mm, but products are also available in lengths up to 100 mm.
Eyes for thicker doors in a retail store are rarely accepted. Most of the time they need to be ordered.


Summing up, we can say that The best way ensure our own security create panoramic eye.

Higher comfort and viewing angle allow you to get only electronic models with a video camera and liquid crystal display, but their price is much higher.

Entrance doors are the boundary between personal space in the house and the outside world, and the stronger they are, the stronger the feeling of comfort and security, but sometimes there is a situation when the owner needs to see and hear what is happening outside his apartment. The optimal solution this problem is the installation of a peephole, the history of which goes back to the distant 1906.

It was then that Robert Wood invented a wide-angle lens, called the "fisheye". Gradually, the opening was improved until a modern version of the peephole was obtained. Today, a peephole can be purchased by choosing from the entire range strictly according to individual preferences of shape, size and functionality.

How is the door peephole

Design modern model door peephole consists of the following parts: two lenses fixed on the sides for comfort.

One of which is directed to an external object, and the second is inward and is an eyepiece. For fastening, an external rail and an internal nut are used. The lenses are hidden in the body, while the number of lenses that can be installed there depends on its length, usually this number varies from 2 to 15 pieces, on which there is a shutter on the inside that covers the eyepiece.

Types and criteria for door eyes

When buying a particular eye model, it is worth considering several basic criteria so that any situation cannot be taken by surprise. As a guide through the door, viewing angles play an important role, and the higher they are, the lower the level of risk.

Thanks to the increased field of view, you can observe the maximum space in all directions and everything that happens on it. The optimal viewing angle is 180°, but quite often manufacturers expand it to 200 to optimize image quality and eliminate distortion in the field of view.

The trick that most manufacturers use is to push the focus to provide coverage. more space. The next factor is the width of the door leaf, on which the peephole model depends: standard (for a door 30-55 mm thick); elongated (for a door with a thickness of 55-100mm); long (within 100mm).

The most common model are standard eyes, which are installed in contemporary designs metal and wooden door panels.

To adjust to the individual width of the door, a thread is used, with which you can fix the desired position. It is worth paying attention to the insulation, unless, of course, it will be used in the near future, because it will add “width”, and the calculated length of a standard eye may not be enough.

The secret of a successful purchase of an elongated or extra long door peephole lies in its optical characteristics, which differ from the standard options. But most manufacturers, in order to save materials, prefer a complete set of conventional, elongated nut, while not taking into account the reduction in image quality.

Not small role the diameter of the eye also plays, while the utility factor is higher, the larger it is. Thanks to the aperture ratio of the lenses, the clarity of the image increases, and from a distance of up to 7 cm from the eyes it will retain its properties of a wide viewing angle. The only nuance-minus for eyes with a wide diameter cannot be completely replaced by models with a smaller diameter.

Eyelet materials

The most popular material for the manufacture of door eyes is still plastic and metal, which ultimately affects the cost of a particular model.

Here you can do without unnecessary comments, because many will agree that hardware durable and stable, which cannot be said about plastic, prone to deformation and cracks.

Door peephole installation

The same goes for the lenses themselves. It is more rational to purchase a peephole with lenses made of ordinary glass or spectacle optics, which, unlike plastic counterparts, do not become cloudy or deformed and, if handled carefully, will last for quite a long time, recouping its cost.

door eyes

1. Task

The door is intended for visual observation of a limited space and is usually installed on the front doors of private and public premises.
The eye of the neck should give a clear picture of objects at a distance of 0.5 to 5.0 m in light and illumination conditions.

Special door eyes can also observe the room through double doors(eye for double doors), security control protection (eye secret) of the observer (bulletproof eyes and periscope eyes), etc. The doors are often duplicated by the television monitoring system, whose operation is less reliable.

second

Neck device

Okance's design may be very different, but in everything that is the small eye of the eye (the lens is rotated around the observer) and the lens (the lens facing the object being observed). There may be other lenses between the eyepiece and the objective. In addition, the optical part of the most attractive structure includes: a housing having an outer and an inner nut. (Fig. 1).

The total number of lenses in the doors ranges from 2 to 15.

Sometimes mirrors (eye-periscopes) are used in the doors.
The most common is the design of the optical system, consisting of four lenses, which provides an angle of 180-200 degrees. without significant image distortion (Fig. 2).

3. Consumer properties of the eye neck

neck thickness is one of the main parameters of the eyes of the cervix. According to this parameter, the eyes are divided into three groups:
- standard eyes (neck thickness 30 - 55 mm);
- oblong eyes (neck thickness 55-100 mm);
– Extremely long eyebrows (door thickness over 100 mm).
Most of the manufactured doors are "standard". These eyes can be placed on modern standard wood doors and on most metal doors.
If the door is finished with various hard and soft materials, the length of the "standard" eyes may not be sufficient.

In this case, it is necessary to install "long" or "very long" cervical eyes.

Eye cutting into metal doors or problems of people with little magnification

Tilt angle the eye of the neck is shown in Fig.
The ideal viewing angle for the neck is 180 degrees. Large when viewed is achieved by "moving forward" in the center of the lens. This provides a complete view of the door zone.
However, it should be borne in mind that in the representation of doors, image distortion often occurs at the edges of the field of view. Therefore, most wide-angle eyes are made with an overestimated viewing angle of -200 degrees, which reduces distortion in the “working” sector by 180 degrees.
When choosing a "long" or "very long" neck, we must not forget that these eyes must have different optical properties than the "standard" eyes.

It's not always noticeable. Some manufacturers produce "oblong" eyes, filling the "standard" eye with an extended rear nut without changing the optical design. Installing an eyelet with such a bunch on a wide door leads to a sharp decrease in the viewing angle.
When choosing a drawer, you should check it at a visible angle as much as possible by unscrewing inner eye, t.

maximizing the "door thickness" parameter.

3.3. Construction of crushers.

Nowadays, almost all of your eyes are equipped with blinds. Without a choke, only cheap eyes are produced.
The damper does not emit light from the apartment and allows the observer to vaguely approach the eye and observe covertly.
Basic requirements for flap design. Loputa Mora:
- close the eye hole;
- Lightweight and silent opening and closing;
- they do not have sharp corners;
— Do not touch the door or door leaf while driving.
The latter requirement is often not provided for in the design of modern and openings, leading to difficulty in turning the valve, damage to the surface of the door, soft cut door trim and, ultimately, damage to the flap.

materials, which are used in the manufacture of cervical eyes, largely determine the selling price of the eye.
Below is a list of materials used to shape the eyes of your neck.

The list is made after the eye price increase:
Glasses with plastic optics:
1. The body and two nuts (external and internal) are plastic;
2. The body and the inner nut are plastic, the outer nut is metal;
third

The body and two nuts are metal.

Glasses with glass option:
4. housing and two nuts (external and internal) - plastic;
fifth

Housing and inner nut are plastic, outer nut is metal;
6. The body and two nuts are metal.
On the other hand, metal eyes are different, one is in the form of metal,
processing method and type of coating.
The cheapest one is the silumin molding neck, which is usually just a paint-covered mat.
Treated eyes have the best appearance and higher costs.

With the same types of outer coverings, non-ferrous metal eyes are more expensive than ferrous metal eyes.
The appearance of the eye largely depends on the type and quality of the coating. And very often around lined black metal it looks better than eye color in bare metal. Thus, the eyes of the Brass door eye "gold" darken over time, and the door made of steel, chrome plated and then titanium nitride ("gold") does not darken and in fact create scratches are not affected.
Eye optics are divided into glass and plastic.
Optical glass, on the other hand, is made from optical, "spectacular" and ordinary glass.

If the properties of optical and glass bottles do not differ much, ordinary glass lenses are more fragile.
Plastic lenses are not afraid of impacts, but they have many important drawbacks: they are prone to scratches; due to electrolysis and the formation of static electricity, they attract dust to themselves, and, finally, most plastic materials eventually turn yellow and lose transparency.

Almost the second - the third year of work with plastic optics, visibility in these eyes is deteriorating.

3.5. Mirror deletion The objective lens lens acts as a pin, and the door valve cannot be installed in the presence of a tick.
If, however, there is a light source behind the neck of the neck, it will be visible from the outside in the form of luminous dots. This means that in this case the mirror lining does not fully realize the function of the flap.
Another defect in spray atomization is the smaller aperture, the "mirror" of the eye, because

part of the light flux is reflected by spraying.
However, the door is a "mirror" in a simple requirement due to ease of use (no need to open and close the flap) and look better.

3.6. I recieved it increase opening on the neck it is allowed not to see it only in poor lighting, but allows the viewer to look into the eyes of a door that is remote from it (up to 5-7 cm).

Sv You do not need to move your eyes closer to the eyepiece eyepiece. At the same time, it retains excellent viewing power.
In enlarged lens eyes, the larger diameter lenses are structured like a normal eye and therefore have a slightly larger diameter of the eye body.

Blowout protection The eyelets on the outside are equipped with most of the meshes produced. Only a few cheap eyes are missing.
The constructive solution for such protection can be very diverse, but the most effective way is the installation of different holders on the outer eye.

Doors for special purposes.
sustainable doors The eyes provide protection for the observer with short tube weapons. These eyes have been tested against the following weapons: Nagant TT Makarov. The observer also represents eye periscopes, which are made on the principle of a periscope and submarines, whose eyepieces and lenses are not coaxial. Because the shot outside the scope of the lens passes by the head of the observer.
Window doors can be fitted with bulletproof eyes and periscopes.
Currently, secret eyes are being created, the design of which was developed in the middle of the last century by special services. different countries for covert surveillance.

The design of these eyes is very different, but common feature- wide view and very small diameter (from 0.5 to 0.8 mm) of the outer lens. The body of the eye is usually pencil-shaped and is located in a wall (or door). At the tip of the "pencil" is a lens that looks and at the level of the outer surface is hidden in the background image.

On the surface of a wooden door, the lens is masked under the head of a nail with a diameter of about 1 mm. In this case, as a rule, a number of real nails with similar heads are stuffed.
eyes for double doors They are designed to be observed through two doors at once (inside and outside) with a regular eye on the outer doors and on the inner doors, which are opposite, attached to the optical device by eyepieces.

The system "optical unit + peholo" allows you to view the room for outside doors without opening the doors.
There is also a demand for doors large diameter up to 50 mm ( "Door-panoramic device"), which uses oiled glass instead of an eyepiece.

On this glass, as on the screen, the image is oriented, allowing for remote viewing without having to approach the door.

4. Manufacturers of door eyes

At home and abroad, the main manufacturers of door neck opto-mechanical device and precision mechanics factory.

The production and installation of standard cells is often handled by small businesses purchasing optics from optics.
Door sales are widely sold out in the Russian market: Russia, Belarus, China and Spain.
The widest range of neck eyes is produced in Russia (up to 100 objects).
Russian plants produce only standard eyes (Vologda, Novosibirsk, Cheboksary, Krasnogorsk, Azov, Moscow, etc.).

There are about 20 titles in total. These eyes are usually equipped with glass optics, but they do not have a good design and price loss, as in the eyes of Belarus and China.
Belarus has more than narrow choice eye than Russia, but in the production of standard cells it occupies a leading position, produces glasses with a good design-price ratio. Glass production is concentrated in the cities of Minsk, Vileyka, Lida and Gomel.
China produces a very wide range of cervical eyes, but only the cheapest low quality glasses are transported to Russia, usually with plastic optics and no dampers.

In addition, lenses are often incorrectly attached to the body with adhesive. The proportion of marriage between Chinese eyes is significant.
Spain in the Russian market represented doors, especially Amig products that produce standard and oblong eyes with good design and at high prices, but often with plastic optics. The brass eyes of this company do not have a protective coating and eventually darken.

about the materials of the company "World of Castles"

Entrance doors providing the highest level security, heat and noisy insulation, have one drawback: it is impossible to determine who is behind the door without opening. And that's exactly what I want to avoid. You can solve the problem by installing a door strip with a special glass cartridge, or by installing an enclosure.

Select combs

The last solution is much easier to implement.

Neck design

The first prototype device served as an observation slot that crossed the door.

The gap was closed with a latch, and the window pounded several times. Surprisingly, it is difficult to imagine such a design in a modern dwelling or home that an alternative to an overhead observation slot existed until the early 20th century.

The starting point was the creation of a special fisheye lens, developed by the American scientist Robert Wood.

A feature of this is the transmission of an expanded image of an external object to an observer.

Modern design looks like this: the body is plastic or metal, contains at least an eyepiece - observation aids and a target. There are locks on the case, due to which the eye cannot be unscrewed from the outside. Internal organization often equipped with a slider. Instead of the latter, a mirror coating can be used to prevent light from passing through the eyepieces so that the visitor does not know if they are looking or not.

The optimal viewing angle is 180-200 degrees.

In the first case, you get an image with slightly blurred edges. More than a watch, without this drawback. But the diameter of the device simultaneously increases. In the photo, the door is equipped with a small eye.

materials

The body of the device is made of plastic or metal.

Another option is more suitable for steel structures or solid wood.

Lenses for the device are made of plastic or glass.

In the case of highly reliable input structures it is recommended to use an eye with an additional armored glass cartridge.

The material is able to transfer a direct hit of the ball from a cannon (short trunk).

Special types of neck eyes

The video shows different types of instruments: panoramic, periscope, hidden, as well as video cameras.

door with video camera

Modern and expensive type of device.

The body diameter is standard, so it can be replaced instead of a conventional device.

Door in the front door

At the same time, the new device is equipped with a wide-angle camera - color or black and white, which transmits the full picture to the monitor or TV. An eye with a video camera is usually also equipped with its own monitor for monitoring.

The camera transmits a live image of the visitor, and if the owner of the apartment is absent, record the date and time of the visit, which allows you to accurately determine who visited the house and when. Since the device with a video camera reacts to traffic, it is registered not only by the guests themselves, but also by all visitors who have crossed the landing.

The eye of the camera can be successfully used to organize your own security system. The photo shows an example of a device with a video camera.

How to install a door peephole with your own hands - an overview of the peepholes and video advice

Today it is very dangerous to open the door without seeing the person on the other side. Of course, it's good to hear a familiar voice, but as they say, it's better to see once than hear ten times.

Based on this, we can say that the door peephole is simply a necessity. The cost of such a device may be different, but affordable for everyone.

Preparing the door for peephole installation

Each owner of his house will be able to install the door peephole with his own hands.

Thread: How to install a peephole?

door peepholes may differ in size, design, price. You can give preference to any peephole, the main thing is that the installation dimensions fit the thickness of the front door leaf. Although, most often, door optical devices can vary widely.

Announcement: How to install door frames

By the way, it is best to give preference to a peephole with a field of view of 170 ° or more, devices of this kind are called wide-angle.

In this case, the "guest" will not be able to cling to the wall and hide from you. In addition, it is better if the outer lens of the eye is made of glass, since plastic is scratched and less durable.

Door peephole installation

In order not to spoil the lining of the door leaf when marking it stands on the outside, glue a paper strip at the required height, you can use masking tape.

On the strip, in any way convenient for you, it is necessary to mark the location of the center of the eye hole. Measure the mounting diameter of the optical device, for a part with an internal thread. Next, select a drill of the required diameter, it should be 0.3 mm larger, ideally use a corkscrew or screw. You can use a small mirror, you need to attach it to the door leaf, with the slightest deviation of the drill, you will immediately see it.

Announcement: How to align the door threshold with your own hands

Drill the door leaf not through, but in such a way that the guide center of the tool used comes out.

Continue drilling on the other side, this will avoid pricking the veneer on the face of the door. Unscrew the peephole into two parts, insert the first part with an external thread from the outside of the door leaf, insert the second part of the peephole, respectively, from the inside of the door, unscrew the parts. Tighten the peephole, to do this, use the slots on the inner frame of the device. In order for the screwdriver not to fall off, it is necessary that the tip of the tool enters both slots.

Suitable thickness steel plate can be used. This completes the installation of the door optical device.
