ETHERNET WIRING REQUIREMENT FOR POE
Connect a Cat5 cable or higher (Cat5e, Cat6) cable (not supplied) to the RJ-45 network connector. The 8-pin
port includes video over Ethernet, and PoE for the camera. PoE (IEEE 802.3af, Class 3) 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.
