This makes me wonder - is it possible to make a "smart camera" with an open-source circuit diagram and laymen-interpretable circuit verification indicators? Like suppose you want to sell a CCTV system for this exact situation, that's got a pretrained detection model implemented on some inference circuitry hooked up to a streaming camera. You publish the circuit diagram and any other operating specifications, and you want to convince people that the physical device they have in their hands is impossible (or at least very expensive) to alter, say by adding a hard drive or wireless modem or whatever. Are there sensors you could attach to the circuit such that modifications to what is interconnected would manifest as deviations from published sensor values? Some sort of md5 hash analog for hardware? That all assumes you've solved the problem of training a good enough detector (presumably from a similar dataset) which has its own difficulties, but OP's question made me wonder about the aspect i described above.
