Power over Ethernet (PoE) requires one wire for both data and power. You also need a PoE network switch, or a “PoE injector” which is basically a power brick that adds power to the network cord.

There are also poe adapters that allow you to power a non poe device. Can be useful in many situations.

Yeah, that would definitely be the way to go. You still have to run the cables all over the place, whether it's one or two. I totally get why people go with wireless.
