    Why there's no product that works as a Powerline Ethernet Adapter with PoE built in?

    I would think this could be a killer solution for a bunch of surveillance cameras and APs.

    One reason I could think out is price. It's understandable the price could be higher, but hopefully it would not cost so much more right? Because a PoE power adapter is ~$20 and HomePlug AV2000 pair is ~$100, and combined ~$140 for a pair is not that overpriced.

    Posted this a bit too hurry - I meant there's no high speed HomePlug, like AV1200 or AV2000. Totally missed this critical point in title. Sorry for the confusion.

    HomePlug targests home users who use primarily Wi-Fi connected cameras. Not a big enough market, I'd guess. Would also increase the size of the adaper due to added heat load.

    other than what @thiggins mentioned, POE increases cost as there are various standards and wattages. Just compare a 250W POE capable switch vs the same switch without POE and the price difference is big. For 3 ports perhaps 60W of POE and thats still significant in size and cost of the power adapter itself. The powerline itself despite having passthrough operates on DC voltage, it has a PSU inside of it.

    Most of the time, there's a lot of cameras required, so you'll need a switch no matter what. And a POE switch is a slight cost increase vs a powerline POE adapter with multiple ports. Probably why it doesn't exist--not enough demand. Plus, you can always get a POE injector if you want for pretty cheap.
