Yep. We have a mix of wifi/hard wired PoE. If you can handle crawling around in the attic or wherever, PoE is the easiest and best option. No need to run wiring to any sort of electrical box to power 110v for cams. Wireless is super-easy, but usually you have to pay for cloud services on top of that. Home hard wired with an NVR or NAS is the way to go.
