TRO-4G/400 is designed for DC power supply and reception of video signals from 4 TRN-1/400 devices (video transformers - transmitters), using twisted pair cable (UTP, FTP) for a distance of up to 400 metersThe signal from the camera led to the input of the TRN-1/400 transmitter, is sent to the TRO-4G/400 receiver via twisted pair cable. In the transmitter and receiver, the impedance of the 75Ω coaxial cable is adjusted to the impedance of the symmetrical cable, which ensures video transmission up to 400 meters.
The TRO-4G/400 receiver allows unstabilized DC voltage (up to a maximum of 40V DC) into the twisted pair cable, which in the TRN-1/400 transmitter is stabilized to 12V DC, allowing to power cameras with a thermostat
