Used Kramer VS-24N 2x1 Composite Video/Stereo Audio Standby - auto Switcher.

S-24N is a 2:1 failover switcher for composite video and stereo audio signals. When the main video signal fails, it automatically switches to the second (reserve) input. When the original video signal is restored, it automatically returns to the first (main) input. In case of interruptions or power failure, the second input is switched to the output. In addition to the basic function of automatic fallback, the device can act as a conventional remotely controlled 2:1 video and audio switcher. To do this, it is equipped with two remote control ports. When the contacts of one of them are closed, the switch switches to receiving a signal from the second input.
