RDL TX-VCR Video Control Relay

Ensure reliable control in your surveillance and security installations with the Radio Design Labs TX-VCR video control relay. Designed to convert the presence or absence of a valid video signal into a dependable control output, the TX-VCR automates recording, alarm logic, and downstream switching to minimize manual intervention and false alarms. The unit features one video INPUT and a LOOP OUT jack (supplied with a 75Ω terminator) so it can be inserted inline or mounted at the end of a video run. Its detection circuit bridges a 1V video line for accurate video presence detection, and the unique power-supply input accepts a wide variety of AC or DC sources—making retrofit and new builds simpler. At just 3" deep and 1" wide, the TX-VCR fits into tight racks and equipment cabinets without adding clutter. Ideal for CCTV, monitoring, and broader security applications, this Radio Design Labs relay streamlines system automation and improves operational uptime. Add the TX-VCR to your next surveillance or monitoring project to secure and simplify video-controlled switching.
