This is NOT a real camera, but it looks like one and is just as effective a deterrent as a real surveillance camera. Although this unit won't catch a criminal, studies have shown that just its presence can prevent crime. The Dome Dummy Camera With Flashing LED features a motion detection LED flashing light designed to fool criminals into thinking they're under surveillance. This product includes mounting screws; it does not have a metal mounting bracket. It also has a built-in on/off switch: just push down on the top of dome to activate or deactivate the unit. Requires 2 AA batteries (not included).
