Product Description

Analog Video Multiplexer over Coaxial

( coaxial cable )

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.
