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
