If it looks like someone is at home, your home becomes less of a target for a break-in. This device acts as a visual deterrent to intruders and burglars by giving the appearance that someone is at home watching TV. It features a realistic TV program simulation with completely unpredictable light and color patterns that never repeat. Energy efficient, it uses less power than a night light. Includes a 4 or 7-hour shutdown timer and has an LED lifespan of 30,000 hours. Equipped with a light sensor that turns on at dusk, it is easy to operate and runs automatically during holidays or evenings out. The TV simulator is a small electronic device that produces light similar to a real television. From outside after dusk, it appears as though someone is home watching TV. The light mimics scene changes, color shifts, and on-screen motion.
