POWER WIRING
CAT5 CABLE
Connect a Cat5 cable (not supplied) to the RJ-45 network connector. The 8-pin connector includes video
and PoE for the camera. PoE (IEEE 802.3af) injects power over the same cabling that carries the network
data, eliminating the need for a separate power supply. This simplifies the installation and operation of
the camera without affecting network performance.
NOTE: The camera will autosense and configure itself to use either a crossover cable or a straight cable.
