ComNet
CNVETX1 Video Encoder and Decoder
ComNet introduced a video encoder/decoder designed for those applications where temperature extremes, vibration, shock, voltage transients and humidity with condensation are present. The all-new CNVETX1 video encoder/decoder is industrially hardened for use in the most extreme operating environments. The CNVETX1 is a single channel video encoder or decoder. It accepts an incoming baseband video signal with duplex audio and serial data for camera PTZ control, encodes it to H.264, MPEG-4, MPEG-2 or MJPEG video compression standards and inserts it onto an Ethernet network.
