Overview

ST-208T/R video balun is a active device that allows the transmission of real-time CCTV video signal via

cost-effective Unshielded Twisted Paired (UTP) cable. Baseband (composite) signals of any type are supported.

 

ST-208T is active video transmitter and ST-208R is active video receiver.

 

ST-208T/R has small size. The power supply is 12VDC. The press fit terminal block of ST-208T/R allows easy

connection of UTP cable input. It transmit 1 channel video signal from camera end via one UTP cable at distance

up to 1200m when used as a pair. The transmission distance of ST-208R reaches up to 300m when used with

SECTEC series passive video transmitter.
