Camera in the door peephole with recording

Security issues are of great interest to everyone today. An important addition to steel doors, intercoms and other precautionary measures is the use of various video eyes. But in order for them to give a normal result, it is necessary to carefully choose the equipment before installation and to know a lot of useful information about it.

Video eyes are becoming more and more popular, actively replacing standard door eyes. No wonder - there is no longer any need to even go to the door to look at the beating and ringing people in the house.

The advantages of such equipment are:

• invisibility to unauthorized persons;
• low price (in comparison with the video shooting full intercoms);
• high strength and excellent shooting resolution;
• video recording in low light and in total darkness;
• the ability to connect video peepholes with video surveillance;
• ease of installation, for which there is even no need to call in specialists;
• the ability to record live images on flash cards.

Video surveillance is desirable to complement the motion sensors and means of recording images - only this format experts consider to ensure the safety to a sufficient extent.

Good video eyes are autonomously capable:

• record a video;
• take a photo of the visitor;
• fix the message that he wants to convey to the owners of the apartment;
• send a photo to the specified in the settings radio.

Almost any modern model is equipped with a default monitor, in most cases it is fixed on the front door.

The GSM module can send messages to certain phone numbers and use mobile channels for telephone calls. Part of the video peepholes uses IP communication (via the Internet).

Camcorders are divided into:

• black and white encased;
• black and white with a full body;
• colored case.

Packageless cameras record the image of the built-in CCD, the highest resolution available to them is 380 pixels, and the photosensitivity is 0.4 lux. The fee for the device is quite small, it has an audio channel. Problems - poor picture quality and complicated installation. Since the peephole looks different from a video camera, it violates the law banning hidden and disguised shooting by private individuals. Therefore it is necessary to install an auxiliary glass bell.

Black-and-white body eyes have an increased resolution compared to unpackaged ones - from 420 to 600 TVL, the sensitivity is 0.1 lux, you can complement them with infrared illumination, the installation is quite simple. If you already have a hole from the usual eye, you can simply fix the lifting device there.

Color case video eyes are divided into square, having a separate tripod, and ordinary ones, which are replaced by old eyes.

Writing what is happening behind the entrance door requires a number of components, primarily external panels and indoor units. Panels are placed on the door leaf, but monitors and other parts can be installed where it is:

• convenient to owners of apartments and houses;
• justified by technical considerations;
• does not bring any inconvenience.

In most cases, video monitors are installed on the walls of the hallways, the mounting height is 1.6 - 1.7 meters. The principle is simple: they looked at the screen and immediately decided to open the door or not.

When eyes with video cameras are placed in country houses, displayed on the street, it is required to ensure good condition during cold weather and heat.

The external details of the video peephole are as follows:

• video camera equipped with a wide-angle lens;
• button to call;
• microphone and speaker;
• infrared illumination unit;
• Motion Sensor.

Camera Sititek Eye - a very simple and elegant model, the external device is no different from the traditional door eye.This is just a monitor with a single control button and anyone can use it. This does not affect the quality of shooting and broadcasting of the image. Shooting begins automatically as soon as someone presses the call button.

Modification Radio DVR has its own radio channel with a frequency of 5800 megahertz and a monitor, a recording device can be placed within a radius of stable signal reception. The Home Lux device was equipped with a camera with a motion sensor; its operation is powered by a rechargeable battery.

Removing the device through the peephole of the device are installed extremely simply. It is only necessary to make a hole of the required diameter at the required height, insert the device there, then connect it to the monitor and recording unit, connect to the network or to another power source. Anything more you do not need to do!

The popularity of video intercoms combined with video eyes, gradually increases, this option helps to prevent hacking and theft, or simply unauthorized entry into the home. Criminals may not suspect that they are being shot.

It is advisable to choose small video cameras that shoot a color image with a resolution of 0.3 to 2 megapixels (this is almost always enough). A wide-angle lens is important because it allows us not to limit the view to the face and figure of those who have come, but it makes it possible to see everything that is on the landing, on the flight of stairs or on the local area.

Infrared LED and autonomous (backup) power are very useful: even if the attackers try to turn off the power supply or take advantage of its failure, it will not be so easy for them to disrupt the video eye. It is possible to communicate with visitors both through the handset, and thanks to the built-in microphone and dynamics, it is desirable that both of these modes can be used.

But the extremely high resolution and clarity of the picture are not needed, because anyway they will not add anything to the result. When mounting a video peephole with your own hands, you need to act as carefully and carefully as possible so that strong compression will not break the device. Wireless video eyes are very difficult to install and therefore it is advisable to entrust this work to professionals.
