IFS 12-Channel Digitally Encoded Video
The IFS VT/VR71230DRDT-R3 video transmitter/data
transceiver and video receiver/data transceiver series
utilizes state-of-the-art 8-bit digital encoding and decoding
for high-quality video transmission that exceeds the
requirements of EIA RS-250C for Medium-Haul Video
Transmission. These environmentally hardened units provide
transmission of twelve independent video channels and two
bi-directional data channels over one single mode optical
fiber and are ideal for use in unconditioned roadside or
out-of-plant installations. Completely transparent to and
universally compatible with any NTSC, PAL, or SECAM CCTV
camera system, all standard pan-tilt-zoom control signals
including RS-232, RS-422, or 2 or 4-wire RS-485 with Tri-state
and Sensornet 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, available in rackmount configuration only.
