Realistic TV program simulation with scene changes, light flickering, onscreen motion and unpredictable color pattern changes. Built-in light sensor turns the device on at dusk with selectable timing settings, giving the illusion that someone is home. 4V WIN TV Simulator is powered by USB with no batteries required. It can be plugged into a PC, power bank, or any USB power source with an EU plug for use in the home or office. Settings include OFF, DUSK+4HRS, DUSK+7HRS, and ON. When exposed to sufficient ambient light (30 lux), the simulator automatically switches off before the 4 or 7 hours elapse. The TV simulator can be placed directly on a shelf or mounted discreetly using the included quick mount plate and 2 screws. Energy-efficient design with low power consumption helps reduce running costs compared to leaving a real television on.
