I saw a wifi camera that replaces a lightbulb. It takes power from the light socket. I don't see why you couldn't make one that also used the power line as a network cable, too. Would require no installation and could be used at your next house.

hardware required for isolation of powerline communication is gonna be hard to stuff in that small of a space. Powerline tends to be sorta unreliable and only runs at like 5-15% of the rated max speed, but if you had buffering at the camera to ensure all frames made it to the otherside, you could work around that.

That’s pretty interesting, does it look like a light bulb? Or it something that uses the socket just as a pass through?

  No or at least the one I have does not. It's similar to this one on Amazon (https://www.amazon.com/dp/B09KMVD13T https://www.amazon.com/dp/B09KMVD13T). I was just looking for a quick and simple solution to check for package delivery. (I'm disabled; so, just hopping up and checking the front porch isn't simple.) I have the camera's app on an old phone, sitting on my desk. It detects motion and I can control it to check the entire porch. Not as good as a wired system; but, it works.

Power line as network cable is a thing, it's called power line communication (PLC, [1]). It was used in some home automation hardware back in the day, probably still used in industrial setting. AFAIU the noise is too high to be useable in residential 1: https://en.m.wikipedia.org/wiki/Power-line_communication https://en.m.wikipedia.org/wiki/Power-line_communication

  Power line Comms is very much alive in residential settings... There are devices that can cram gigabit data rates onto home AC wiring. They're a great alternative to running new ethernet runs. They are controversial with other radio users, because while the devices themselves don't emit much RF energy, your home wiring and wiring in the street will typically radiate most of the high frequency data into the air, disrupting FM radio and lots of other sub 500 Mhz radio users.

    There's also MoCA ethernet over coax cable, https://www.techreviewer.com/learn-about-tech/ethernet-over-coax-a-complete-guide-to-moca-adapters/ https://www.techreviewer.com/learn-about-tech/ethernet-over-... > I was trying to get a good signal upstairs, downstairs, and outside at the same time. I didn't want to run an Ethernet cable out a window or drill a hole in a wall or floor, so I was stuck with moving around a Wi-Fi access point. That was until I realized that I already had wire in the walls—coax cable! But wait, you can't use coax cable for Ethernet communication, can you? The answer turned out to be yes, you can!

    Thanks, I stand corrected.
