Coaxial cable multiplexer
( analog video multiplexer )
1.2 Channel Coaxial video transmitter (Model:CY-921T/R)
Overview
It supports 2channel video signals in one coaxial 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 under new projects.
Feature
1. It’s designed according to projects with minimum installation volume requirement.
2. 2-CH video in one coaxial cable transmission
3. FDM technology is easy for multi-channel signals transmission only in one coaxial cable without any delay
and interference.
4.The knob built in the Receiver supports actual transmission distance adjustment for a best signal output.
5.Transmission distance over coaxial cable SYV75-5 is 0~600M, while the transmission distance over coaxial
cable SYV75-3 is 0~400M.
