There is an effort at https://community.home-assistant.io/t/popular-a9-mini-wi-fi-camera-the-ha-challenge/230108/300 to add HA support for at least some of these cheap A9 cameras. They are relatively cheap costing less than 5 euro in some cases(temu aliexp). I have been able to run the PinScan example via telnet.

I have some difficulty navigating the source code but I think the action is at https://github.com/daniel-dona/beken7252-opencam/blob/main/project/beken378/func/camera_intf/camera_intf.c

I would be happy to help as I know C(who doesn't with GPT these days) but I am not familiar with the arduino framework.
