Each owner seeks to secure his home, whether it is a house or an apartment. This can be achieved in many ways, one of which is the installation of a modern security system in the apartment in the form of a video intercom with motion sensor and recording.
Video intercom with video and sound recording
The modern video intercom has a variety of functions. With it, you can view the space in the staircase and directly near the entrance to the apartment. In addition, the device allows you to negotiate, not coming directly to the door. In addition, when connecting a video intercom to the access door, you can open its lock without leaving the apartment.
It should be noted that all the listed set of functions of a conventional video intercom can be used in the event that the owners are in their apartment. A more modern device is able to record photos and videos even in the absence of hosts. This video intercom uses internal built-in memory.
It should be noted that such a device does not work for recording permanently, but turns on when you press a call or on a motion sensor, that is, when someone is standing in front of the door. You can buy a video intercom for an apartment with a motion sensor and a recording that will turn on at the appointed time. A intercom connected to the Internet allows you to record video and even monitor the situation at the apartment door, communicating with invited or uninvited guests through a tablet or smartphone.
Information in video intercoms with video recording can be stored on an SD card or on a hard disk, which is often set to be hidden. There are multi-channel intercoms capable of recording from multiple cameras. Saved records can be viewed on the video device itself. In addition, having withdrawn a memory card, you can study the recorded video on the computer.
When choosing a video intercom a lot depends on the manufacturer. Chinese devices are considered the cheapest, but the quality of their work is not always good. Average for the price are video intercoms of Korean production: they have more developed functional and better quality in comparison with Chinese ones. And the most interesting are the models of European manufacturers. The devices with support for GSM, WiFi and IP can be used for remote control and monitoring. However, such video intercoms have a rather high cost, that's why they are available only for wealthy people.
