 signals transmitted by one cable 

4 channels Real Time color Quad multiplexer4CH video/3CH video+1CH negative data

1,as project demand,the device is optimized interface,and is convenient for installment with mini volume;

2,Transmit 4 channels video or 3 channes video +1channel negative RS485 control signal optionally through selector switch;

3,RS 485 control interface can be driven by special chip with 15Kv anti-stastic module ,which can be 64 nodes;

4, under HS frequency reuse way, signals are combined with high speed without any delay and disturbances;

5,adjustable knob is installed in receiver,which can fine adjustment transmssion distance,so that get better video effect;

6, brightness degree of video signal can be adjusted at the transmitter according to different camera;

7,12V DC power supply,built-in protective circuits;

8,all ports use high quality IVXBNC interfaces;

9,ocular data transmission status with RS485 signal indication;

The device has high energy conservation circule
