Booster / Multiplexer, video + RS485 over coax, kun til videoovervågning

• Superstrong video anti-jamming ability
• Built-in lightning protection module.
• Transmit video and random RS485 signal in one coaxial cable (realize optional video and RF)
• Long transmission distance(it can transmit 800m with 4 grade effect image under SYV75-5 coaxial cable. The control signal can reach the high-speed ball control signal demanding)
• Anti-stastic device with isolation circuit:prevent master-control room to be disturbed from outer static
• Automatic recovery without adjustment:device can adjust indication automatically within the proper range.

Different from traditional coaxial cable, which only transmit 1 channel video signal ,more signals can be transmitted in one coaxial cable, which saves investment, simplifies construction and achieves better effect; products can realize to transmit video, power, control, audio, broadcast, phone signals and so on, clients can choose available product according to demand. The products are used in new projects and modification works, which can help to save 80% investment at most according to different environments. (2channels,3 channels,4channels video and control products and relevant ones)
