Why choose the POE NVR Camera System? 1.Simple Power Supply: only need to power the recorder or switch to propagate to many cameras; 2.Energy Saving: When using POE power supply mode for centralized power supply, because the power receiving equipment has the function of supporting the power identification circuit, it will not cause waste of electric energy; 3.Simple Maintenance: each camera is connected by a network cable, and there is no need to maintain the power supply, power cord, power socket, etc. in the later stage; 4.High Safety: there is no strong power at the camera, and there is no need to worry about the risk of leakage in rain and snow.
