I am fairly militant about privacy and data security so I go POE and self hosted. My cameras are all wired and sync to a server in my basement. I trust no corporations.

That said the cameras I have are reolink. They do have options for WiFi cameras that use apps and such but I don’t use this. You can also use the app with the POE camera but I don’t do this.

I have the cameras on an isolated lan with no internet access. All of my smart home stuff is like this. If it doesn’t work on an isolated vlan then it is useless to me and I won’t buy it. I then forward the rtsp stream from the cameras to homeassistant which has tailscale so I can view the cameras remotely.

At one point I used homebridge in homeassistant so I could view everything in homekit but I finally convinced my partner to just use the homeassistant app and leave apple nonsense behind. That said if you’re less paranoid than me this works too and gives you remote access without the bother of tailscale (but the downside of funneling it all through apple).

Of course, if you research and trust reolinks app then using that is the easiest thing. I haven’t done that tho. I believe amcrest cameras are also good but these are also primarily POE
