How to assemble a door peephole - types of structures and installation recommendations. How to install a peephole in a metal door yourself

The peephole, as well as when choosing and installing it, should be guided by safety and the conditions for maximum view of the site, taking into account the material itself front door... Dear s maximum level field of view have a 180-degree angle, which allows you to view the area right down to the rug under yours. The panoramic viewing angle of the cheaper options is about 120 degrees and does not give any particular advantages either in efficiency or in the quality of viewing the site.

Today, video eyes with a built-in camera connected to a computer or laptop like a standard webcam are quite popular.

If you are going to buy and install on your own peephole, do not forget to take into account the thickness of your door leaf. You can easily choose the length of the eyelet body and its diameter from a wide range. Remember that the length of the eyelet can be additionally adjusted using the threads on its body.

Traditionally, door eyes are made of plastic and metal, while their optics are glass and polymer (as well as plastic). The advantages of glass optics lie in a better image quality, resistance to mechanical damage (scratches and dust), as well as in the absence of clouding.

Eyes, the most optimal in terms of their qualities and characteristics, have a metal body and glass, but their cost is higher than that of budget door models.

Installation in the door

The installation of a peephole in the door is carried out taking into account the height of the owner of the apartment. It is necessary to mark the center on the door, based on the desired height, and mark the resulting mark with an awl - this will not slip. Also, before marking the installation site, glue on the selected area door leaf a strip of duct tape. Now you can place notches without fear of ruining the door lining.

To prevent chips from forming in the door when drilling, the marking of the future hole is performed on both sides of the door.

Having chosen the diameter of the drill (slightly larger than the diameter of the threaded element of the eyelet), start drilling the marked holes on each side of the door, plunging the drill into half the thickness of the door leaf. Unscrew the peephole and install the part with external thread, and part with internal thread- from the inside. After the holes are drilled, screw the peephole into the door, tighten it with the splines and enjoy a safe view of the staircase.

The front door protects the property from outside interference. She protects households from the views of strangers. But it is also necessary to know what is going on around the apartment or house. For this, door eyes are used. According to the norms, 0.5-3 meters of the space around the door should be visible through them. For sale different models with interesting functions: for a double door (installed in two panels at once), hidden (it is invisible to others), protective (bulletproof). There are optics that perform signaling functions.

The door peephole was created by tester Robert Wood. It happened in 1906, but the technology began to be used only after 1960.

A simple system consists of:

• lens-lens, which expands the view outside the apartment;
• an external rail securing it;
• side lens retainers;
• hulls;
• an inner nut connecting the outer and inner lens to each other;
• an eyepiece that points inward;
• dampers.

The thinner the door is, the smaller the case will be, the fewer lenses will be installed in it. The models sold in stores have between 2 and 15 eyepieces.

Main characteristics

Characteristics include length, angle, material of manufacture, diameter, type of valve. The parameters are selected depending on the type of door on which the equipment is mounted. The functions that the device must perform are also taken into account.

Eye length

The length depends on the thickness of the door. According to this characteristic, all models are divided into:

• standard - from 30 to 55 mm;
• long - from 55 to 100 mm;
• extra long - from 100 mm.

The standard kit is enough for apartment doors.

If the doors are additionally upholstered with bulky materials, the peephole length up to 55 mm is not enough. Therefore, long or extra-long versions are used.

Viewing angle

As a standard, the viewing angle is 180 degrees. This is possible by shifting the focus of the lens up, but design features distort the incoming rays. Manufacturers compensate for the inaccuracies by increasing the viewing angle to 200 degrees to achieve 180 degrees.

Long and extra-long eyes have different optical parameters. Some firms sell equipment in which the optics are equipped with a rear nut. In this case, the optical scheme does not change.

Execution material

According to the material of manufacture, models with plastic or glass optics are distinguished. The equipment is divided into the following subspecies:

• two nuts and a body - plastic;
• inner nut and body - plastic, other parts - metal;
• two nuts and a metal body.

The more metal is used in production, the higher the cost of the product will be. The eyes of their silumin lithium will be cheaper, and more expensive - from black metal.

The glass optics give a good image, not blurry, but they are quite fragile. Plastic is not afraid of blows, but scratches remain. The image is not as clear. In addition, yellowness develops over time.

Product diameter

The diameter of the door optics is different. In standard variations, it ranges from 2 to 3 centimeters. Manufacturers produce models with a diameter of more than 5 centimeters.

Eye latch, analogs

Latches and dampers allow you to discreetly monitor and protect the apartment from light. Correctly installed valve:

• does not have sharp corners;
• closes tightly and prevents light rays from entering the entrance;
• when opening and closing, it does not come into contact with the optics and the door.

The analogue of the valve is mirror spraying. It makes the image less bright and clear. At the same time, the buyer of a model with a mirror coating does not worry about the damper scratching the fittings.

Types of door eyes

The kind that has simple design and a viewing angle of 180 degrees is considered standard. Other models have been developed that work in a similar way, but at the same time increase the viewing angle and give great protection... Among them:

• or a fish eye, which has two lenses - the space around the door is seen better;
• a bulletproof version made of special durable materials that protects people from intruders;
• secret, which is in an unexpected place, which is why it is invisible to others;
• double - designed for a double door, allows you to see what is happening behind the outer door;
• periscope - convenient for families with small children or people with disabilities (convenient to view from a low distance);
• , which is a miniature copy of the simplest CCTV camera;
• the model with a motion sensor notifies the owners when there is activity outside the door.

Smart views are able to track what is happening at the entrance and record information to an external drive. They consist of a camera, monitor, power supply. A microscopic camera is placed inside the peephole. The equipment is invisible to others.

How to choose?

When choosing a door option, it is important to consider the technical characteristics. Among them important parameter- viewing angle. The standard options are 180 degrees. This does not allow to provide reliable protection... Periscopes, telescopic nozzles allow you to increase the viewing angle, make visible the space near the door itself. Also, attention should be paid to:

• Light sensitivity. These data are written in the parameters. If they are high, then you can see what is happening behind the door with minimal lighting at the entrance.
• Type of shell. Models without a case are easier to assemble and install, but case models are more reliable.
• Manufacturing material. Serve longer hardware... Plastic ones are not reliable, although they are cheaper.

Door optics are selected based on design features and protection requirements. Buy a modern version for an ordinary apartment irrational. A simple one is clearly not suitable if there are a lot of valuable things at home. To prevent strangers from entering your home, it is better to buy high-quality equipment.

Installing the door peephole

Installation of standard equipment is fast. You can do this yourself. Electronic video eyes, which transmit information to a digital screen, are mounted longer, because the master lays the cable from the door to the recorder according to the scheme. The procedure for installing a simple peephole is as follows:

• marking the door in the selected place;
• drilling a hole with a punch or drill (size depending on the size of the eyelet);
• installation on the outside;
• twisting the base on the inside.

It is better to entrust the installation, assembly of periscopes, double models, smart door peephole to professionals. They will be able to collect them securely.

Those who are a little familiar with plumbing can install themselves, following the instructions. You need a drill or perforator, a ruler for measuring, a level. When working, it is necessary to observe the boundaries so that the peephole does not hesitate and is tightly in contact with the upholstery.

Manufacturers

It is impossible to single out any one manufacturer as the best. The buyer's strategy is to study the parameters and characteristics of the product. Then decide how the products fit the requirements. Well-known manufacturing companies:

1. German ABUS. The assembled equipment is durable. There are peepholes for private apartments and country houses.
2. Chinese Armadillo. She provides a line of good products. There are eyes made of various materials, interesting colors, sizes. There are additional functions.
3. Russian NORA-M, DOORLOCK, Apecs, Torex. The eyes are distinguished by an advantageous ratio of quality and cost. In the presence of certificates corresponding to GOST.

In order for the equipment to completely suit the buyer, it is important to consider for what purposes it will be used. It is possible to get by with the standard options if the house has a central lock on the entrance. How to choose the right peephole is a topical question if people live in a disadvantaged area. In this case, it is better to focus on modern case models. The correct peephole on guard of property will help control security in an apartment or house.

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 allow you to follow what is happening on 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 body of the peephole 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 enlarge 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 light transmission.

Lenses, in turn, can also be of two types: glass and plastic. Plastic is comparatively 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 peepholes 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 the wood one, but in modern doors layering is practiced, therefore steel door may be thicker than the 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. Panel doors 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 Special attention devote the class to the door itself.

Door peephole: types

Standard... The eyepiece and lens form a single line and are positioned opposite each other. The simplest and most affordable peephole option. It is customary to install it on simple models doors. 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... Represents more complex structure... There are two eyepieces on the inner side, and a lens on the outside. The image is transmitted to the second eyepiece using mirrored lenses. Why is such a design needed? For easy operation 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 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 body diameter 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 peephole model. Moreover, metal doors are often supplemented inner lining from MDF and decorative elements, which complicates the task somewhat.

Stages of installation of the viewing device in metal door:

1. Use chalk or pencil to mark the location of the future peephole. Consider the height of all family members and choose an average.
2. In order to avoid deformation of the interior door trim or its covering, stick the foil or electrical tape on the place of drilling.
3. Measure the diameter of the peephole body. If the part has an internal thread, use a drill half a millimeter wider than the result.
4. You need to drill from the inside, directing the drill to the outside of the door.
5. Do not drill through the door. Get to the outer layer exterior decoration and stop. Then drill with outside... This little trick will help you avoid chipping, chipping, or bumps.
6. A lens is installed from the outside. From the inside, respectively, the eyepiece.
7. 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.

Views

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

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

Advantages

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 is approaching 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 will know that someone is near the door. The system is adaptable for both residential and office space and warehouses. It is an excellent addition to your basic room alarm system.
• No need to apply for a license. Classic systems video surveillance is 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 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, it will be necessary to increase the diameter. 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 on your own.

Video eye connection: video

The choice of complexity, price and type of door peephole depends on factors such as: the class of the door, 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 match in their technical specifications 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.

Our life now is such that you can open the door for a guest only by making sure of who is actually on the other side of it. Hearing a familiar voice, of course, is good ... But, as they say, "it's better to see once ...". And there is nothing shameful here - "God protects those who are careful!" Because the peephole is a must, dictated by a harsh time. It is not so expensive, but you can install the door peephole in the door leaf yourself.

Eyes on sale are very different in design, size, and price. You can choose anyone for yourself, the main thing is that its installation dimensions correspond to the thickness of the leaf of your front door. But, as a rule, they can vary widely in almost all eyes.

It is also desirable that the angle of the field of view is at least 170 ° (such eyes are also called wide-angle). Then the "guest" cannot hide from you and huddled against the wall by the door. And it is better if the outer lens is made of glass rather than plastic - it is less scratched and therefore more durable.

How to install a door peephole with your own hands

	In order not to spoil the lining of the door leaf when marking, on the right height Sticking on a strip of paper adhesive tape, such as a painting tape. Anyone on it in an accessible way mark the position of the center of the hole for the peephole.
	Having measured the seating diameter of the eye (for a part with an internal thread), a drill of a slightly larger diameter is selected - by 0.3-0.5 mm, best of all - a screw or corkscrew.
	Having drilled the door leaf not through and through, but only so that the guiding center of the tool goes out, the hole continues to be drilled from the opposite side. Thanks to this, it will be possible to avoid veneer chipping on the front surfaces of the door.
	Having expanded the peephole into two parts, one (with an external thread) is inserted from the outside of the door leaf, and the other, respectively, from the inside, and screwed together by hand.
	The peephole is tightened using the slots on its inner frame. To prevent the screwdriver from falling off, its tip must go into both slots. You can simply take a steel plate of a suitable thickness.

Why call a master if you can cut in the peephole yourself.
This is the opinion of most of those who have ever held a locksmith or carpentry tool in their hands, but not as a specialist, but as an amateur.
If someone at least once had to deal with this issue, then he will definitely say that let everyone go about their business.

How easy or difficult it is to put 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, but if it is metal, then this is quite another.
At first glance, it may seem that it is more difficult to cut a peephole into a metal door. But here just everything can be the other way around.

Difficulty peephole in a metal door can only consist in the strength of the metal, and everything else is likely to go like clockwork.
Yes, drilling a hole in a 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 no more than 2 mm thick.
Making a hole for a peephole 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 both for the door itself and for the master.
At the exit, the drill may jam and break, possibly causing serious injury or injury.
A 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 decorative trim.
If you do not observe all the necessary for inserting the eye finishing material may suffer, and then the cost of cladding will also be added.
In a word, for such an insignificant procedure as an insert, it is worth preparing thoroughly, and if there is the slightest doubt about the positive conclusion of this issue, it is better not to take up the work.

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

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

These products are very widespread in the market. There are very cheap and very expensive models... Let's try to find out what makes each other different and whether it makes sense to pay more.

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

The attackers learned to simply "trick" them. To avoid gaze, it was enough to press against the wall by the door or sit on the threshold. This feature is the result of the small viewing angle of cheap products.
Experts recommend mounting lugs which looks like 180-220 degrees. This is better, better. You also need to consider the fact that the edges of the 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 almost 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 reach the door and press your eyes to get the shot.

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

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

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

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

They are also capable of building up static electricity, which attracts dust particles. And the material itself eventually becomes destructive and loses its transparency. In short, after a few years, the images transmitted by such lenses become blurry and unclear.
More Recommended tie with lenses made of ordinary glass.

And the best option is special glasses products for glasses. It fully transmits the luminous flux and is characterized by increased power.

Of course, such models are the most expensive.

But they will serve regularly for many years.

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

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

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


Summing up, we can say that The best way to ensure our own safety - create a panoramic eye.

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

Entrance doors are the border between the 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 door peephole, the history of the creation of which goes back to the distant 1906.

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

How the door peephole works

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

One of which is aimed at an external object, and the second inward is the eyepiece. An outer rail and an inner nut are used for fastening. The lenses are hidden in the body, and the number of lenses that can be installed there depends on its length, usually this number varies from 2 to 15 pieces, on which a shutter is located on the inside, covering the eyepiece.

Types and criteria for door eyes

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

Thanks to the enlarged 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 extend the focus to cover more space. The next factor is the width of the door leaf, on which the peephole model depends: standard (for a door with a thickness of 30-55mm); extended (for doors 55-100mm thick); long (within 100mm).

The most common model is considered to be standard eyes, which are installed in modern samples of metal and wooden door leaves.

For adjustment to the individual door width, a thread is used, with which you can fix the desired position. It is worth paying attention to the insulation, if, of course, it will be used in the near future, because it will add "width", and the calculated length of the standard eyelet may be insufficient.

Secret happy shopping the door eyelet of the elongated or extra-long model lies in its optical characteristics, which differ from the standard versions. But most manufacturers, in order to save materials, prefer a complete set of conventional, elongated nuts, while not taking into account the reduction in image quality.

The diameter of the eye also plays an important role, while the coefficient of utility is higher than it is larger. Thanks to the aperture 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 wide angle for review. The only nuance-minus in eyes with a wide diameter cannot be replaced without a trace on models with a smaller diameter.

Peephole materials

The most popular materials for the manufacture of door peepholes are 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 metal products are durable and stable, which cannot be said about plastic, which is prone to deformation and cracks.

Installing the door peephole

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, will not become cloudy or deformed and, if handled carefully, will last for quite a long time, having recouped its cost.

Door eyes

1. Task

The door is intended for visual observation of confined spaces and is usually installed on the entrance 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 under lighting and lighting 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 eye-periscopes), etc. Doors are often duplicated by a television monitoring system, the operation of which 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 observed object). 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 design of the optical system is four lenses, which provide an angle of 180-200 degrees. without significant image distortion (Fig. 2).

3. Consumer properties of the neck of the eye

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 wooden doors and most metal doors.
If the door is finished with various solid and soft materials, the length of "standard" eyes may not be sufficient.

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

Cutting eyes into metal doors or low magnification people problems

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" at the center of the lens. This provides a complete view of the door area.
Keep in mind, however, that image distortion often occurs in the door view at the edges of the field of view. Therefore, most wide-angle eyes made with an overestimated viewing angle of -200 degrees, which reduces distortion in the "working" sector - by 180 degrees.
When choosing an “elongated” or “very long” neck, we must not forget that these eyes must have different optical properties than “standard” eyes.

This is not always noticeable. Some manufacturers produce "oblong" eyes, fill the "standard" eye with an elongated rear nut without changing the optical design. Installing an eyelet with such a bundle on a wide door leads to a sharp decrease in the viewing angle.
When choosing a drawer, you should check it from a visible angle as much as possible by unscrewing the inner eye, i.e.

maximizing the parameter "door thickness".

3.3. Construction of crushers.

Nowadays, almost all of your eyes are fitted with blinds. Only cheap eyes are produced without a choke.
The damper does not emit light from the apartment and allows the observer to unclearly approach the eye and observe covertly.
Basic requirements for flap design. Loputa Mora:
- close the eye opening;
- Easy and quiet opening and closing;
- they have no sharp corners;
- Do not touch the door or door leaf while driving.
The latter requirement is often not foreseen in the design of modern and openings leading to difficulties in turning the valve, damage to the door surface, door trimming soft and, ultimately, damage to the flap.

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

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

The body and two nuts are metal.

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

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

With the same types of outer coatings, 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 ferrous metal, it looks better than the eye color in bare metal. Thus, the eyes of the brass door of the eye "gold" darkens over time, and the door made of steel, plated with chrome, and then titanium nitride ("gold") does not darken and in fact scratches are not affected.
The eye optics are divided into glass and plastic.
On the other hand, optical glass is made of optical, spectacular, and ordinary glass.

If the properties of optical and glass bottles not much different, ordinary glass lenses are more fragile.
Plastic lenses are not afraid of impacts, but they have many important disadvantages: 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.

Practically the second - third year of working with plastic optics, the visibility in these eyes deteriorates.

3.5. Mirror removal The objective objective 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, it will be visible from the outside in the form of luminous points. This means that in this case, the mirror lining does not fully realize the function of the flap.
Another defect in atomization is the smaller aperture, the "mirror" of the eyes, because

part of the luminous flux is reflected by the spray.
However, the door is a "mirror" in a simple requirement due to its 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 it allows the viewer to look into the eyes of a door that is far from it (up to 5-7 cm).

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

Blowout protection The eyelets on the outside are equipped with most of the manufactured nets. Only a few cheap eyes are missing.
The design solution for such protection can be very diverse, but the most effective way is to install different holders on the outside eye.

Doors for special purposes.
Stable doors The eyes provide protection for the observer with short-tube weapons. These eyes are tested for protection against the following weapons: "Nagant" TT "Makarov". The observer is also an eye periscope, which is made on the principle of a periscope and submarines, the eyepieces and lenses of which are not coaxial. Because a shot outside the scope of the lens passes the observer's head.
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 the special services. different countries for secret surveillance.

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

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

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

On this glass, like on the screen, the image is oriented, which allows you to view it remotely without approaching the door.

4. Door eye manufacturers

In our country and abroad, the main manufacturers of the door neck of the opto-mechanical device and the factory for the production of precision mechanics.

The production and installation of standard cells is often handled by small businesses buying optical devices from optical devices.
Door sales are widely sold on 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 items in total. These eyes are usually equipped with glass optics, but they do not have the good design and loss in price, as in the eyes of Belarus and China.
Belarus has more narrow choice eye than Russia, but in the production of standard cells takes a leading position, produces glasses with a good ratio of design and price. Glass production is concentrated in the cities of Minsk, Vileika, Lida and Gomel.
China produces a very wide range of cervical eyes, but only the cheapest low quality glasses are shipped to Russia, usually with plastic optics and no dampers.

In addition, lenses are often not properly adhered to the body with glue. The marriage rate between Chinese eyes is significant.
Spain has represented doors in the Russian market, especially Amig products, which produce standard and oblong eyes with good designs and high prices, but often with plastic optics. The brass eyes of this company do not have protective coating and eventually black out.

about the materials of the company "World of Castles"

Entrance doors providing highest level security, heat and noise insulation, have one of the disadvantages: it is impossible to determine who is behind the door without opening it. And this is exactly what I want to avoid. You can fix the problem by installing a door strip with a special glass cartridge or by installing a case.

Select combs

The latter 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. It is surprising that it is difficult to imagine such a structure in modern dwelling or home, that an alternative to the top observation slot existed until the early 20th century.

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

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

The modern design looks like this: the body - plastic or metal, contains at least an eyepiece - observation aids and a target. There are latches on the case, because of which the eye cannot be unscrewed from the outside. The indoor unit is 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 watching, without this flaw. But the diameter of the device is increasing at the same time. 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.

The lenses for the device are made of plastic or glass.

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

The material is capable of carrying a direct hit from a ball from a cannon (short trunk).

Special types of neck eyes

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

Door with video camera

A modern and expensive type of device.

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

Front door

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

The camera transmits an image of the visitor in real time, 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 camera eye can be successfully used to organize own system security. The photo shows an example of a device with a video camera.

How to install a door peephole with your own hands - peephole review and video advice

Today it is very dangerous to open a 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 peephole is just a necessity. The cost of such a device may be different, but affordable for everyone.

Preparing the door for the installation of a peephole

Every owner of his house will be able to carry out the installation of a door peephole with his own hands.

Topic: How to install a door peephole correctly?

Door eyes can vary 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 trims

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

In this case, the "guest" will not be able to cuddle up to the wall and hide from you. In addition, it is better if the outer lens of the peephole 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 is on outside, at the required height, glue a paper strip, 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 bore diameter of the optical device, with 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, at the slightest deviation of the drill, you will immediately see it.

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

Do not drill through the door leaf, but in such a way that the center of the used tool protrudes outward.

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

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