Frequently Asked Questions
Q- Can I connect the modules to any computer network equipment?
A- NO! Do not connect the UTP cable of the Video Encoder or Decoder to a computer network! Doing
so could damage the attached devices! The Decoder ouputs DC voltage on pins 7 and 8 of its UTP
connector that some network equipment may not be prepared to handle. Each Encoder/Decoder pair
needs a dedicated point-to-point circuit; nothing else can share their wires. Also, they are not IP or Power
over Ethernet (PoE) devices so they will not work properly with network hubs, switches, or routers.
Q- Can I connect the modules to other UTP type video systems?
A- NO! Do not connect the UTP cable of the Video Encoder or Decoder to other video systems! Doing
so could damage the attached devices! As mentioned above, the Decoder output voltage could
damage the other devices. Also, the other devices may damage the Encoder or Decoder. Even without
the power issues, the modules’ video transmission signal is proprietary so the other devices will not be
able to recognize or display it properly.
Q- How can I see the video on my TV without using an expensive security monitor?
A- The composite video signal from the UTP 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 1000 feet?
A- Though we do not recommend or support doing so, some people find that the modules function
satisfactorily at distances greater than 1000 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 do the DIP switches inside the UTP Decoder module do?
A- The switches come preset from the factory in the OFF position. This requires the least amount of
intervention for most installations. Some monitoring devices though, are more sensitive to the voltage
level of the video signal and will require an adjustment of the switches according to the length of the
UTP cable. In those situations, disconnect power from the Decoder and remove one of the end plates.
Then locate the switch bank and, starting from #1, set each switch
ON until the most satisfactory
picture is attained. The longer the cable, the more switches that will need to be ON.

turn more ON as the cable length increases; turn them all ON for the longest distance, 1000 feet.
