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
Applications
Security monitoring system. Multimedia network teaching system. Medical monitoring display system.
Industrial automation control system. Banking securities. Financial information display system. Remote
network server monitoring. Department store security
Casino security. Hospitals, airports and banks. School campuses
