It is probably a two part process.
First part is to set a camera and make it provide a feed.
Then you need a part to process that feed to look for the changes you need to react on.
The first part is just a standard webcam and maybe a small light to make it see the changer.
The second part might be possible with Frigate NVR or some other AI processing setup. AI processing can be done with Google and Amazon cloud services, but also with local services, which might be enhance with a Goggle Coral USB stick.
