4-channel 8-bit digital video receiver with

4 cont

act closures over 4 optical fibers

Description

The ComNet™ FVR4C4B Video and Contact Closure Receiver unit
supports four independent channels of video and four independent
dry contact closures over four separate optical fibers. State-of-the­art 8-bit digital decoding is utilized for the four video channels. The
contact closure channels may be used with triggered-event CCTV
camera systems, or other applications such as access controlled
gates, doors, or other equipment requiring remote actuation and
control. Plug-and-play design ensures ease of installation, and
no electrical or optical adjustments are ever required. Bi-color
(Red/Green) LED indicators are provided for rapidly ascertaining
equipment operating status. The high channel density of the
FVR4C4B makes this unique product ideal for those installations
where space may be limited. Packaged in the exclusive ComNet
ComFit housing, these units may be either surface/shelf-mounted
or rack-mounted, or may be DIN-rail mounted by the addition of
ComNet model DINBKT1 adaptor plate. The FVR4C4B Receiver
is fully compatible with ComNet’s model FVT1C1B-M Video
Transmitter unit.
