Do you mean wifi or wired? If wired, then that’s pretty much any camera…
An example: I’ve just bought THIS mini camera on aliexpress and it works pretty much “out of the box”:

  • connect camera to power and LAN - usually has DHCP turned on so it get’s IP automatically

  • see in your router which IP has been assigned to camera

  • login to camera’s www page and change IP to static one; also change compression from h265 to h264 (or HA won’t be able to show picture)

  • add camera in HA (onvif integration)

  • you can also use addons like WebRTC - it can show rtsp stream

when setting up wifi cameras sometimes sadly you do need app, but just for initial setup, later it’s not needed anymore.
