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 premises 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. This unit contains a flashing red LED light which draws extra attention to the camera, particularly at night. For a lower priced version without the flashing light, please see item DDC. Installs quickly and easily to the ceiling or wall using the included screws. The base measures 4 1/2" across and the dome is 2 3/4" high. Requires 2 "AA" batteries.
