I have two Amcrest out door wifi cameras (and their doorbell IP camera), IP3M-943W and IP4M-1028W, both look to be out of stock and probably discontinued.. there is a newer one on Amazon called ASH42-W, have not research it at all.. but I can tell you, WIFI out door cameras are not a great option. The wifi on them is very poor and trying to blast wifi through walls, in my case CBS, is extremely difficult. I run multiple Unifi wifi access points in my house, mainly so that I can place one right next to the wall on the other side of each of these cameras to try and blast wifi through. This works, yet still every day like clockwork at 6pm when everyone in the neighborhood comes home and jumps on wifi AROUND ME, the cameras start to drop off line due to the congestion in the air waves. Lots of transmission failures, and thats with "enterprise" access points. Everyone next door streaming youtube and netflix over 2.5Ghz plus my cameras.. its a mess.. If you want to try something for cheap and see how it goes, wyze cams are pretty crap, but will give you an idea if you can get wifi to work where you want. Video loads over wifi are not at all the same as browsing on your phone... its a constant stream, and it will hammer wifi.. dont invest too much into it before trying I would recommend.
PoE is a more technical problem to solve, but the quality of the video is so much better. Much higher quality images, 4K video at 30fps, crisp bitrates, you can actually see the thing you are trying to record..it doesnt cut out in the rain or afternoons.. worth it.
