Dual Independent AM Video Receiver with
Manual Gain Control and Loss of Video Relay
FVR21/LV
HARDENEDINCLUDED
The ComNet™ FVR21/LV dual video receiver detects two independent AM video
signals in one module on two independent multimode fiber optic cables. 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 Manual Gain Control. The receiver is
compatible with the ComNet™ FVT11M and the FVT20 dual video transmitter. Plugand-play design ensures ease of installation.
