This realistic looking dummy security camera fits easily to a wall, or under your gutters. It is battery operated, and when installed, it looks just like the real thing. Whenever anyone approaches, the built in motion sensor activates the "camera", and it pans from side to side, as if it was tracking the movement of the visitor. A red LED flashes to help convince the person near the camera that it is activated. A great product to use along with other sensible precautions, such as window locks, burglar alarms, gates etc.
