About the Power Connect Feature
The Power Connect feature applies as long as the cable can carry power. This
feature is available when using STP cable and the distance does not exceed 50m
(164ft) on standard CAT 5 cable. For longer distances, heavy gauge cable should
be used (CAT 5 cable is still suitable for the video/audio transmission, but not for
feeding the power at these distances).
For units which are connected via RJ-45
connectors, make sure that the shield of the STP cable is connected to the metal
casing of the connectors on both ends of the cable. For units which are connected
via terminal block connectors, the shield of the STP cable must be connected to a
ground terminal on the units at both ends (use the ground terminal of the power
supply connection if necessary).
For a CAT 5 cable exceeding a distance of 50m, separate power supplies should
be connected to the transmitter and to the receiver simultaneously.

Shielded Twisted Pair (STP)/Unshielded Twisted Pair
(UTP)
We recommend that you use Shielded Twisted Pair (STP) cable, and stress that
the compliance to electromagnetic interference was tested using STP cable. There
are different levels of STP cable available, and we advise you to use the best
quality STP cable that you can afford.
Our non-skew-free cable, Kramer
BC-STP
is intended for analog signals where skewing is not an issue.
In cases where there is skewing, our Unshielded Twisted Pair (UTP) skew-free
cable, Kramer
BC-XTP
, may be advantageous, and UTP cable might also be
preferable for long range applications. In any event when using UTP cable, it is
advisable to ensure that the cable is installed far away from electric cables, motors
and so on, which are prone to create electrical interference.
