With this system you can record 720p high quality color video during the day, then at night the cameras will automatically switch to night vision mode with built in infrared LEDs providing illumination up to 20 meters from each camera. 

With Power Over Ethernet technology,a single network cable is needed from each camera to the recorder, carrying both power and video data. When the cameras are plugged in, they will automatically be configured and assigned a channel on the recorder, making set-up a breeze.
