Now you can deter robbery, theft, and vandalism without the high cost of a real security camera. When placed in your home or business, even the most sophisticated criminals will think the premise is guarded by a high-tech surveillance system and go in search of an easier target. In fact, this is an actual dome surveillance camera that has been modified into a "dummy" or fake security camera. This dome dummy camera is designed to imitate the small, high tech security cameras on the market today. NOTE: to stop or start the flashing light simply push down on the top of the dome until you hear a click. The flashing LED Light makes it noticeable, even at night. The base measures 4 1/2" across and the dome is 2 3/4" high. Installs quickly and easily using the included screws. Requires two AA batteries. Covered under a one year warranty.
