Comnet FVR22/LV Datasheet

Dual Independent AM Video Receiver with

Automatic Gain Control and Loss of Video Relay

FVR22/LV

INCLUDED HARDENED 2

The ComNet™ FVR22/LV consists of two independent AM video fiber optic receivers in one module. It uses two independent multimode fiber optic cables to receive two separate signals from two transmitters. The module is not a multiplexer. The unit incorporates a “Loss of Video” relay for each channel. Upon loss of video signal or optical fiber break, the normally closed relay opens. The module is ideal for CCTV installations and the rack mount version can be used to double the fixed video capacity of the C1 rack for up to 28 independent video channels per card cage. The modules utilize Automatic Gain Control (AGC). The receiver is compatible with the ComNet

FVT11M and the FVT20 dual video transmitter. Plug-and-play design ensures ease of installation.
