ST-204 is a 4 channel passive video transceiver. 4ch video transmission or 3ch video transmission and 1ch data
transmission. PAL/NTSC/SECAM realtime video transmission. Exceptional interference rejection and buil-in protection
setting. Convenient wiring installation. Higher cable utilization rate and lower composite wiring cost.
DSA (Distance Self-Adapting) Technology
Employing the advanced DSA technology, it can adapt to the cable length and adjust the video signal gain control
automatically, identify its polarity and compensate the frequency bands. Video quality is more Human-based.
Complete Solution
A set of complete UTP transmitting solution is provided. Its advanced technology in UTP transmitting field and plenty
producing lines offer more options in CCTV system transmission and bring totally new worthy experience to you.
Guarantee for Long Distance Transmission and Video Quality
Sectec twisted pair transceiver employs advanced processing technology, zooms out and compensates the attenuation
of video signal levels and different frequencies, keeps the original video sharpness, color and resolution, realizes a good
transmission of middle and long-distance video signals and solves the problem that coax cant reach the long transmitting
distance. If work with Sectec series passive transceiver, transmission distance is up to 400m and if working with active
receiver distance can be up to 1200m.
Higher Cable Utilization Rate
Sectec twisted pair transceiver transmits video, audio, data and power, which makes it convenient to form a multi-class monitoring system.
Flexible and Convenient Wiring Cuts down Project Cost
UTP is softer and lighter than coax, making its easier, more convenient for wiring installation. Specially in integrated systems,
cable utilization rate is increased and design change is decreased greatly. Meanwhile, UTPs price is lower than coaxs,
which greatly cuts down the cost for wiring installation.
Exceptional Interference Rejection, suitable for Complicated Working Environments
Exceptional interference rejection; no interferences between signals; even under strongly interfering environments,
good video can be transmitted.
Built-in Protection Setting, Stable and Reliable
Built-in surge protection, lighting protection and other protection settings, reliable and stable, making working system safer and more reliable.
Applications
Security Monitoring System, multimedia Network Teaching System, mMedical 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 and so on.
