I’ve been using neomailbox for almost 10 years for this, so maybe check them out

Another thing to try before replacing the whole pan if the screw is too rounded/stripped to back out is a screw extractor set. You basically drill a small hole in the screw for the extractor bit to bite down on, then use the extractor bit to back the screw out. The extractor kits are generally fairly inexpensive.

I’ve had good experience with amcrest cameras. Most you can activate locally, and have rtsp.
