The fully functional motion sensor looks like any other motion sensor, just plug them in and you have video. You can hook up the motion sensor to your alarm too! The high quality CCD camera built inside the camera is virtually hidden. An integrated 2.4 GHz 4 channel transmitter is used to create a wireless system for ease of placement and include a matching 8 channel scroll selectable receiver. Why 8 channels? This allows the user versatility in a wireless application. Each Motion sensor has a choice of black&white or color camera.
