About the product1. This product bound the video signal of the camera and the control signal of RS485 reverse controller in one coaxial cable transmission. It use frequency division multiplexing technique, which means the control signal and video signal in different frequency modulation, and composite together transmission. It can transmit four channel homonymous or reverse transmission video signal and RS485 control signal in one cable. It can transmit 600 meters by using common video cable, which can enhance the utilization rate of cable, also it has many characteristics, such as a clear image, easy for installation and so on. 2. It has solved control signal transmission over a long distance, greatly extended video signal transmission distance. The transmission way save material and cost, construction is convenient, without debugging, stable, reliable, etc. System extension and transformation is more flexibility. It is an ideal equipment of control signal transmissionIllustration1. Signal input be connected receiver 2. Line out 3. DC12V power supply 4. Power supply indicator lamp 5. Video signal out 6.
