In the era of Internet of things, the demand for monitoring equipment has been continuously strengthened, and the market for outdoor PoE switch has been developing rapidly.
Typically, a network camera needs two external wires, a cable, and an electric wire. In some special situations and situations, the camera will be installed without power supply, or the camera is installed with power supply, but it is lighting power supply, which can not provide all-weather power supply. These will lead to the network camera is not working properly, but the PoE technology is not the same, can through the cable power supply, no need to install a power socket, completely solve the power problem of video monitoring installation.
At present, PoE technology is widely used in video surveillance systems, which can supply power to video cameras and transmit network signals.
