i use yi home camera (4 pack on amazon for $72 currently) which runs over wifi and firmware via https://github.com/roleoroleo/yi-hack-Allwinner-v2. this bypasses the app and internet connection entirely. you will need some microSD cards to flash and run the cameras.

this exposes RTSP/ONVIF and also allows for local motion detection and recording capabilities.

i also use https://www.scrypted.app/ to handle MQTT for motion detection events from the camera and restream to apple home to take advantage of notifications on my phone, remote streaming, etc.

this works fairly well, the downsides are that the install process is probably more involved than it should be, and the stand it comes with is just /ok/ but the mounting bracket is such that you can 3d print your own fairly easily. 1080 stream quality is good enough tho i'm sure there are better quality cameras on the market.
