PoE - Faster, Easier & Lower-Cost Installation
No power cable or adapter is needed. the camera with Power over Ethernet (PoE) technology can transmit power and data simultaneously via one single network cable. Less wiring, less cost, more convenience.
But if you don' t have any PoE injector/switch/NVR, you also can prepare a 12V1A power adapter to power on the camera and also connect the camera to the router by Ethernet cable.
