Video door to the front door

In our time, the issue of security has really bothered many people. Various security systems have long become an integral part of not only offices, enterprises and factories, but also private houses and apartments. Of course, the ideal solution to the problem of private property security is the installation of serious locks, lever or electromechanical , and a system of permanent video surveillance, but this system will not be affordable for everyone. But technological progress does not stand still and the arsenal of home security is constantly being replenished with new inventions. One of these novelties was the door video eye - the device, which is installed on the front door instead of the usual door eye and consists of a lens and a video camera. This device allows you to remotely watch on the TV or video monitor everything that happens behind the entrance door.

How to choose a video eye?

First of all, you need to solve the question - why do you need video eye and what functions will it perform? Perhaps you want to make your life easier and with this device you want to know who has come to you, not coming to the door, and maybe you need 24 hours of hidden video surveillance, recording information and saving it to the DVR.

So, depending on their preferences, as well as financial opportunities, each consumer can purchase:

1. Black and white video eye with a video camera. Its main advantage is the relatively low cost, and the disadvantage is the small resolution of the video matrix and the obvious difference from the usual door-eye;
2. Black and white video case with IR illumination. This camera has an excellent resolution, simple installation, but its cost is almost 2 times higher than the cost of a video camera;
3. Color hull video eye. Of course, the big advantage of this device is the color image, but its quality is much inferior to black-and-white case video-eyes, besides, its price is much higher.

In addition, according to the way information is transmitted and recorded, door video eyes are wired and wireless, analog and digital.

Also, when choosing a video eye, you should pay attention to the viewing angle. According to this criterion, there are currently two types of eyes with a viewing angle of 160 ° -180 ° and 90 ° -120 °. Thus, if your front door is in the side of the corridor, then the model with the maximum viewing angle is ideally suited for you, so as to exclude the possibility of omission of any details. And for a door located at the end of the staircase, cameras with a viewing angle of up to 120 ° will suffice, allowing you to view what is happening afar at a distance of up to 3 meters.

Additional features of door video-eyes

If you need 24 hour video surveillance it is worth to choose the door video-recording with the recording. With this function, you you can be aware of even those visits, which were carried out during your absence from home. Of course, the choice of such a device significantly increases the level of security, but it should be noted that the recording function requires the purchase of an additional device for storing information. You can also purchase a video eye with a recording consisting of a camera, a call and a panel with a LCD monitor that is attached to the inside of the door.

Also on sale are models of video eyes with a built-in motion sensor. This function activates the operation of the device with the slightest movement in the frame, even in conditions of minimal illumination.
