Q-Can I connect the coax between the modules to video distribution equipment?
A- NO! Do not connect the F-Connector coax of the Video Encoder or Decoder other video
equipment! Doing so could damage this product and/or the other attached devices! The
Decoder ouputs DC voltage on the coax that other equipment may not be prepared to handle.
Each Encoder/Decoder pair needs a dedicated point-to-point circuit; nothing else can share
their coax. Also, the modules will not work properly with RF splitters, diplexers, and amplifiers.
The RCA Video Out jack of the Decoder can connect to composite video equipment such as
monitors, TV's, DVR's, and modulators
Q-How can I see the video on my TV without using an expensive security monitor?
A- The composite video signal from the PoC Decoder can be plugged directly into one television's
RCA Video Input jack and viewed when that TV is switched to the proper input. Another option
is to feed the Decoder signal into a modulator. A modulator, such as NetMedia's MM70,
changes the video to a UHF or Cable channel and allows the signal to be distributed to all your
TV's along with the existing antenna/cable/satellite service.
Q-Will the modules work at distances beyond 100 feet?
A-Though we do not recommend or support doing so, some people find that the modules
function satisfactorily at distances greater than 100 feet. At that range, the video quality
degrades as the cable length increases but until the power gives out over the next few
hundred feet, it may still be acceptable for your application.
Q-What is the difference between Power over Coax and modulated devices?
A- Both are similar because they enable One Wire Video™ using a single coax. They differ though
in their type of video output signal. Our modulated devices, such as the RM70 (which supplies
remote power for popu;ar 12VDC cameras), output a TV channel that requires a TV tuner to
view. This is handy for distributing the signal to all the TV's with the same coax, splitters, and
amplifiers that transmit the local antenna, cable, or satellite signal. It is more inconvenient
though, for using the signal with equipment that does not have a tuner such as a security DVR
or Quad screen display. Our PoC modules and cameras output a composite video signal that is
directly compatible with such equipment. Whole house distribution can still be accomplished
with PoC by modulating the output of the DVR or Quad.
