VT/VR4930WDM
Security
Overview
The IFS VT/VR4930WDM video transmitter/data transceiver
and video receiver/data transceiver units utilize frequency
modulation for high video transmission quality. These
environmentally hardened units provide the simultaneous
transmission of video and full-duplex data over one single
mode optical fiber and are ideal for use in unconditioned
out-of-plant or roadside installations. Completely
transparent to and universally compatible with any NTSC,
PAL, or SECAM CCTV camera system. All standard pan-tiltzoom control signals including RS-232, RS-422, and 2-wire
RS-485 data are supported. Plug-and-play design ensures
ease of installation and no electrical or optical adjustments
are ever required. LED indicators are provided for rapidly
ascertaining equipment operating status, and these units are
available in either stand-alone or rack mount configurations.
