AN-VB**0 video balun/stretcher is designed to transmit **0~***0m video monitgoring signal over Cat5 cables. It needs low cost cables only, and uses cat 5 /over 5 shield/not shield twisted-pair. One couple twisted-pair transmit one channel good quality video signal, the other twisted-pair could transmit audio signal or RS**5 date, but it also could be used to transmit more video signal. Different signals could work independently and not interfere with each other, the transmit distance is *******0 m. Video stretcher has good ability of anti-interference, and it is widely used in elevator, electrical factory, steel works manufactories and so on. Such a transmit way has many advantages: convenient wiring, simple installation, good anti-interference, good transmission, low system cost. Video stretcher uses traditional wiring for intelligent building, housing district and other monitor field and offer good quality of solution. AN-VB series is balance – unbalance transmitter and receiver for video stretcher ; it takes cat 5 or cat over 5 twisted-pair as transmit medium and transmit solid or color PAL, NTSC, SCEAM video signal. The device could adjust simply for better show performance; as it has good anti-interference, anti – irradiation to magnet and electricity , it could transmit telephone , RS**2/**5/**2, audio ,multi-channel video ,low voltage on the same cable. As four couple wire for one 5 cat shield/not shield twisted-pair, any couple wire could transmit one channel video , audio or date; four couple could transmit four channel video or combination of video, audio or date with no jamming and also have instant protect when it has impact inside. Possible applications: Monitor center interconnection; Intelligent transportation system( ITS); High-speed way video monitor system; TV program exchange transmission; Close TV industry monitor; Electricity safe monitor system; Water project safe monitor system; High not-infidelity video conference
