Amcrest cameras seem a bit pricey to me when you move to outdoor models, but the indoor are very reasonable. I just looked on Amazon and see your model listed as in-stock, shipped and sold-by Amcrest Direct for $56

Unless you are not in the States and they are unavailable to you.

Also, pretty much any camera can be PoE with either adapters at both ends (injector and splitter) or a PoE to 12v (or 5v) on the camera end. I have a few places I use these and if you get good quality they last!
