1, POE Injector Cable Connection
There is a pair POE Injector cable coming with camera, it gives an option to install the camera as a POE camera even you do not have a POE device, connect one part to camera and connect the other part to power+router, then you could use just a single Ethernet cable to transfer both power and data, the distance is up to 60ft, this is a simple way to supply power if there is not a socket near the camera position. PS: If you already have a 48~52V output POE device, please search H2MD6PA instead, it can connect to POE device with a single cable directly.
2, Traditional Connection
If there is a power socket near the camera position, I recommend this traditional way: Connect to 12V/1A Power adapter (included) directly and Connect to Router with a Ethernet cable directly.
