Homeplugs (ethernet over power) are fine for some things, but they add so much latency to the network.
Wired is so much better.

I've heard of power over Ethernet (PoE for IP cams) but not Ethernet over power.
Yup, there is also Ethernet over coaxial cable TV.
It's kinda niche, especially with improvements in WiFi over the years.
I thought HDMI to Ethernet to HDMI was cool the first time we had to do it for a project in a large room. Hdmi starts running into issues at around 25-50ft. You can go a lot further with the Ethernet cable
There is also POE over two unshielded copper wires.
