Introduction

Via video multiplexer method,realize 4 channels video signal transmission in one video SYV or SYWV cable,also,realize 3 channels video and 1 channel negative data transmission by change-over switch.

All data is in real time transmission,HD image ,no delay

Suitable for NEW project or modification works.

Product function and features

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

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

3,RS 485 control interface can be driven by special chip with 15Kv anti-static 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 transmission 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;

8,all ports use high quality IVXBNC interfaces;

9,ocular data transmission status with RS485 signal indication;

The device has high energy conservation circule
