4G surveillance cameras

 

— network models (IP cameras) with built-in mobile communication modules that allow you to connect to the Internet via 3G / 4G networks.

For such a connection, usually, it is necessary to install a SIM card from a mobile operator in the camera. And the speed of 3rd and 4th generation mobile networks allows, among other things, to broadcast video in a fairly high resolution. So such a connection (of course, with coverage) is well suited not only as a fallback in case of interruptions to the Internet, but also as the main communication channel if there is no fixed Internet connection at all. A typical example of the second situation is the observation of a country house located "far from civilization", but in the zone of reliable mobile communication reception. In both cases, you can contact the camera via the Internet from anywhere in the world.
