200M Video+Audio+Power Anti-Jamming Video Balun

Use twisted-pair cable instead of coaxial cable to transmit video signal and power, can make use of present LAN circuit ,the 4th or 5th wire to transmit video, the 7th,8th transmit power（only direct connect, no converting through router or HUB, etc）.Effective distance: 500M～600M, adopt Differential transmit theory, better performance at anti-common code interference, even at strong interference application, its performance is much better than coaxial cable, and through processing video signal, its image clearer, each twisted cable at most can transmit 4ch audio or video signal, it is at most save cost.
