|
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
