Global Cach's GC-SV1 Video Out Sensor monitors the power status of video equipment by detecting the presence of a composite video signal. The Video Out Sensor is an excellent way to determine the power state of video equipment. When your VCR or DVD player is powered up, a video signal will be present even if the tape or DVD is not in play mode. The Video Out Sensor can be plugged directly into the Global Cach's GC-100 Network Adapter connecting the sensor to the network. Additionally, the Video Out Sensor will work with other controllers that provide 5V power and accept digital logic (TTL) input. The Video Out Sensor connector is a standard 3.5mm stereo jack. It requires +5V to operate, and it provides a sensor output representing the presence of a composite video signal.Global Cach's Video Out Sensor is designed to connect seamlessly to Global Cach's GC-100 Network Adapters. It detects video standards employing negative-going sync NTSC, PAL and SECAM signals with amplitude from 0.5V to 2.0V p-p.
