So the nest outdoor camera is powered by plugging into an outlet. It comes with a basic cord where you plug one end into the camera, and plug the other end into an outlet. Thankfully, it also comes with an extension cord that increases the length of the wire if your outlet is far away. It also comes with wall clips so that your wire does not hang loosely. There is nothing else needed to wire it in. All you need is an outlet, the wire, the wall clips, an IOS or android device, and a good internet connection. Let me know if this helped!
