Deters robbery and shoplifting without the high cost of a real surveillance camera. Features a built in motion detector. It will remain still until someone passes by, then the camera will move back and forth and a red light will flash. To draw extra attention, sound has been added to this model. In addition to the camera panning back and forth and a red light flashing, a beeping sound can also be heard. Unlike our standard model (CHO1) which can only operate on three "AA" batteries, this model features a built in AC Jack that allows the camera to be powered by either batteries (not included) or an AC adapter (not included).
