The camera will need to be plugged in, and you have 2 choices.
1) Plug the power supply in near the camera and run the power supply wire to the camera.
2) Use a PoE kit and run power through an Ethernet (network) cable. In this case you will run a network wire from your router to the camera. The camera's power supply will be plugged in to an outlet near the router.
In either case, the electrical wiring is not complicated as long as you have an easy way to run the wire to the camera.
