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. Powered by USB with no batteries required. Can be plugged into a PC, power bank, or any USB-powered device with a standard power adapter for home or office use. Settings: OFF, DUSK+4HRS, DUSK+7HRS, ON. Automatically turns off when exposed to sufficient ambient light (above 30 lux), even before the 4 or 7 hours have elapsed. The TV simulator can be placed directly on a shelf or mounted discreetly using the included quick-mount plate and two screws. Energy-efficient design with low power consumption helps reduce operating costs compared to leaving a real television on.
