With the development of society and the improvement of the economic level, security issues have received more and more attention from us. First of all, we should be clear, what is the purpose of installing video surveillance? Look up the video after the event, find the cause of the accident, and go through it before…
The focal length of the lens is different, the viewing angle and range that can be monitored will also be different. The following are the visible distances and ranges of some common focal lengths. You can refer to them when choosing a camera. 2.8mm, viewing angle 90 degrees, viewing distance 5-6 meters 3.6mm, viewing angle…
Lens focal length The camera lens is generally divided into two kinds of fixed focus and zoom. We should choose a lens with a suitable focal length according to the scope and size of the scene to be monitored. General fixed-focus lenses mainly have focal lengths such as 2.8mm, 3.6mm, 4mm, 6mm, 8mm, 12mm, 16mm,…
The choice of camera function is based on our surveillance needs, choose cameras with different functions. 1. The transmission method, we can choose, video cable transmission, network cable transmission, WiFi transmission, wireless AP transmission, 4G mobile network transmission and other different transmission methods of the camera. 2. Audio function, if we need to monitor the…
