Now you can deter robbery, theft, and vandalism without the high cost of a real security camera. This item is an actual dome surveillance camera that has been modified into a "dummy" or fake security camera. It is designed to imitate the small, high tech security cameras on the market today. When placed in your home or business, even the most sophisticated criminals will think the premises are guarded by a high-tech surveillance system and go in search of an easier target. The dome has a 24/7 red blinking LED light. Installs quickly and easily with the included screws to the wall or ceiling. The flashing light is optional; to have it simply install 3 AA batteries (not included), to stop the light flashing simply remove the batteries. The base measures five inches across and the entire unit measures four inches high. The unit requires 3 AA batteries that are not included. Battery life is approximately 6-8 months.
