Overview
The ST-1200T/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-1200T is active video transmitter and ST-1200R is active video receiver.
The ST-1200T/R has mini size. The power supply is 12VDC. The press fit terminal block of ST-1200T/R allows
easy connection of UTP cable input. It transmit 4 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-1200R reaches up to 300m
when used with SECTEC series passive video transmitter.
Features
1. Properties : 1 Channel active video transceiver& receiver
2. DSA (Distance Self-Adapting) Technology
3. Distance: transmission distance is up to 1200m via UTP cat5e/6
4. Safety: exceptional interference rejection; no interferences between signals; even under strongly
interfering environments, good video can be transmitted
5. Higher Cable Utilization Rate
6. Video famat: NTSC, PAL & SECAM video format compatible
7. Power: 12VDC power supply
8. Connector: Male BNC connector, press-fit terminal block
9. Compatible with all cameras with built-in UTP transmitter
10. Flexible and convenient wiring cuts down project cost
11. Full ground-loop immunity
12. Compact size
13. Black ABC plastic housing
