Overview
4ch Video Multiplexer 4 BNC with RS485 Control is special designed for adding monitor cameras, upgrading old project and new difficult project of video surveillance system. By using of frequency-division multiplexing and signal superimposing technology, it can superimpose 1-ch 485 control signal (PTZ control or audio signal)(PTZ: Pan/Tilt/Zoom) or 1-ch video signal into another 1-ch video signal in a same coaxial cable, which can add more monitor cameras by the original video coaxial cable. It is the first choice for both new project and upgrading old project because of reducing the difficulty of project and saving wire material.
Features
1. Flexible and convenient selection of signal superimpose: 1-ch 485 control signal (PTZ control or audio signal) and 1-ch video signal or 2-ch video signal can be superimposed in a same coaxial cable according to the need of project.
2. Support all communication protocols: no protocol or baud rate limitation for Rs 485 transmission.Long stable work time by using of advanced solutions and high performance integrated circuit.
3. Easy to assemble and unassembled, plug and play by using of plug design, support hot plug.
4. All aluminum shell, elegant appearance, high shield, good heat dissipation.
5. Easy installation, simple operating, free from adjustment.
