The Kramer 705 is a
high performance composite video to twisted pair transmitter,
and the 704 is its companion unit which converts the twisted
pair format back to composite video. Transmission via twisted
pair cable carries video signals farther than conventional coax
cable, and is lighter and significantly less expensive. A simple
system consists of a 705 located at the video source, and a 704
located at the remote display device. For systems with multiple
monitors, the 704 receiver has a loop out and termination switch
allowing several 704 receivers to be placed on the same TP cable
driven by a 705. Even at a cable length of 400 meters, the
frequency response is well over 6 MHz and at shorter distances,
they provide close to broadcast level performance. Recessed gain
and equalization controls are provided to optimize signal
levels. A 12V power supply is provided with each unit. The 705
and 704 are part of the Kramer TOOLS family of compact, high
quality, and cost effective solutions for a variety of
applications.
Typical
Applications:
-
Remote monitoring
for CCTV, medical, schools, broadcast applications.
-
Ideal for
existing facilities with TP cable already installed
-
Teleconferencing
in offices and hospitals using existing intercom or telephone
wiring
