This is the device that mimics the flickering glow of a television to deter potential intruders. Its built-in microchip simulates the scene changes, fades, swells, and color shifts of an HD television as perceived from outside using a bright multi-color LED display. It can be operated manually or using its integrated light sensor that automatically turns the device on at dusk and off after five or seven hours. Unlike leaving a live television on while away, the device occupies as much space and energy as a night light. AC adapter. 3" L x 2 1/2" W x 2" D. (8 oz.)
