DESCRIPTION

The TRO-4G/400 is designed to power with DC voltage and receive video signals from 4 TRN-1/400 devices (video baluns - transmitters) via twisted pair cable (UTP, FTP) over a distance up to 400 meters. Video signals from cemaras connected to the TRN-1/400 transmitter inputs are sent to the TRO-4G/400 receiver via twisted-pair cable. Both transmitter and receiver units adapt 75Ω coaxial cable impedance to twisted-pair cable impedance, what guarantees the video signal transmission up to 400 meters.

The TRO-4G/400 receiver supplies un-stabilized voltage (maximal up to 40V DC) to twisted-pair cable, and the TRN-1/400 transmitter converts it into 12V DC stabilized voltage, what enables power the cameras with thermostat.
