The project is designed to actuate a relay whenever an input video signal is fed to it. For example, it can be used for switching OFF a TV automatically once the video signals are not available.
This simple circuit activates a relay when it senses a composite video signal. Video signals are amplified by a transistor to drive a relay through another driving transistor. While the video signals are not available the driving transistor switches OFF to turn OFF the load.
