Overview
ST-1801T/R video balun is 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-1801T/R is an active video transmitter and ST-1801R is an active video receiver.
ST-1801T/R has small size. The power supply is 12VDC. The press fit terminal block of ST-1801T/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 2400m when used as a pair. The transmission distance of ST-1801R reaches up to 500m when used with
SECTEC series passive video transmitter.
Features
