3.1 About the Power Connect™ Feature
The Power Connect™ feature here means that only one unit in a system, the
transmitter or receiver, needs to be connected to a power source when the
devices are within 90m (270ft) of each other. The Power Connect™ feature
applies as long as the cable can carry power and the distance does not exceed
90m on standard TP cable. For longer distances, use heavy gauge cable (TP
cable is still suitable for the video/audio transmission, but not for feeding the power
at these distances)
