Realistic TV program simulation with scene changes, light flickering, onscreen motion, and unpredictable color pattern changes. Built-in light sensor turns the TV simulator 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. You can plug it into your PC, power bank, or any device with a USB port in your home or office. Settings: OFF, DUSK+4HRS, DUSK+7HRS, ON. When exposed to sufficient ambient light (approx. 30 lux), the TV simulator automatically switches off before the 4 or 7 hours have elapsed. The TV simulator can be used right out of the box and placed on a shelf, or mounted discreetly using the included quick-mount plate and 2 screws. Eco-friendly design with low power consumption helps reduce running costs compared to leaving a real television on.
