1. Wireless transmission: no need to set up communications cable2. Image, audio sync, color compatible3. Small size, light weight, easy to carry, good installation4. Responsive, timely, send and receive real-time transmission5. Using FM mode, anti-interference ability, good image qualityThe wireless video transmission equipment is an excellent all aspects of performance are more varieties, and its power margin, more suitable for complex physical environment. The use of 0dB (small antenna) in full to the antenna, the open area to the transmission 5-10km or so, if the raising of the high gain directional antenna, increased to 12KM , it can be reach up to 100KM on UAV/helicopters. And transmitter technology is superb and the special metal is more conducive to heat, more suitable for long hours of work. Signal input with common AV interface, it can easily work with camera, VCD, DVD and all other conventional AV interfaces compatible.Transmitter:Working frequency: 1.2G HzOptional channel: 6-CHTransmission power: 5000MWWorking voltage: DC 12VWorking current: 1200MAWorking temperature: -50-90 Working humidity: 85% RHVoice signal: 2VP-P 2KOHMDistance: 800-3000 metersReceiver:Working frequency: 1.2G HzChannel: 12-CHWorking voltage: DC 12VWorking current: 280MAWorking temperature: -50-90 Working humidity: 85% RHImage signal: NTSC/PALVoice signal: 2VP-P 2KOHMSensitivity: -85DBColor: GoldMaterial: ABS+metalPackage Contents:1x TransmitterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
