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, creating the impression 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-powered device with a standard outlet at home or office. Settings: OFF, DUSK+4HRS, DUSK+7HRS, ON. When exposed to sufficient ambient light (approx. 30 lux), the unit automatically turns off even before the 4 or 7 hours have elapsed. The TV simulator can be placed directly on a shelf or discreetly mounted using the included quick-mount plate and two screws. Energy-efficient design with low power consumption helps reduce running costs compared to leaving a real television on.
