The Thermostat Wireless Camera is a fully functioning plug and play surveillance system, with a high quality CCD camera built inside (the camera is virtually hidden). We integrate a 2.4 GHz 4 channel transmitters to create a wireless system for ease of placement and include a matching 4 channel receiver. Why 4 channels? This allows the user versatility in a wireless application. Each Thermostat has a choice of black and white or color camera. If wireless is not the solution you are looking for we also stock wired versions of the same high quality item, please let us know.
