4channels video over one coaxial cable
4channels video over one coaxial cable
Function and Application:
This series of products support multi-channel video signals and control data RS485 in a single SYV or RF cable by way of Frequency Division Multiplexing, with all data transmission real-time and all images high-definition and non-delay.
It is suitable for improvement of old projects and building of new projects.
Features:
High-speed Frequency Division Multiplexing technology is adopted so that several channels of signals can be multiplexed without transmission delay or interference.The knob for adjusting transmission distance built in the Receiver support adjustments according to actual transmission distance for best signal output.Built-in video adjusting button in the Transmitter can cooperate with different video cameras. With energy-saving circuit to achieve best energy efficiency ratio.Transmitter | |||||
