Remote video surveillance
through Internet channels has already become one of the most popular and useful options for security systems. Video surveillance via the Internet has become popular due to the availability of high-speed fixed and mobile access points to the Internet - CDMA and GSM networks of the new generation, LTE networks.
When using modern video recorders (DVRs), IP video cameras or video servers, it is quite simple to provide the function of video surveillance over the Internet, the important point is to use a video recorder (DVR) or IP video camera with two independent streams of video data: the main stream (high resolution) is intended for recording and viewing video information on the server (DVR), and an additional (regulated) stream - for the transmission of video information over the local network and via the Internet.
In the presence of high-speed access to the Internet (from 1.5 Mbit / camera), it is possible to monitor a remote object without losing the speed or quality of the original image (4CIF, 25 k / s, H.264 compression, frame size 7.5 KB - color video camera) on the server (DVR). It is very important when choosing a provider and a communication channel to connect equipment at a remote facility to pay attention to the speed of outgoing traffic ("for transmission"), because usually providers declare the speed of incoming traffic ("for download"), which is usually 3 -10 times more than the speed of the original traffic. In Ukraine, there is a fairly developed Internet access network, and 4G wireless Internet is present in a significant part of the territory of Ukraine, which makes it possible not only to watch videos on a smartphone, tablet, laptop from a remote object, but also to organize a broadcast of a video stream from a remote object at an acceptable cost. When organizing a communication channel, it is desirable to set a static IP address on the server (DVR) side of the remote object. Devices for viewing video information can be: smartphone with Android OS, iOS, tablet, laptop, etc. Remote video surveillance on the client can be carried out in two ways - by installing special client software, or setting up a WEB server on the server side (possible on almost all DVRs) and viewing video through standard WEB browsers (both on laptops, smartphones and tablets).
