TTR-16/SV - VIDEO TRANSFORMER WITH OPTO-ISOLATION
Video signal transmission from 16 different cameras via twisted-pair cables. The device adapts the impedance of a coaxial cable 75Ω to the impedance of twisted-pair cables ensuring video signal transmission for a distance up to 400m.
Each from 16 video channels has an output opto-isolated from input, which protects it from:
- lightning discharges,
- voltage differences and strokes,
- electric currents in video signal cables.
The device eliminates signal disturbances that take place with transmission over several hundred meters distances.
