Texas Instruments and Beaglebone I’ve used this setup, but it takes some programming knowledge (or at least it did a few years ago). Incredible picture quality but smallest image that could achieve sharp focus was about 12x18

I wish I could give you a specific answer, but codes vary by region and you’ll want to meet the expectations of the person doing the final inspection.

Ask your inspector/permit office. I’ve always found those folks to be very helpful. It’s your tax dollars, use them when you need them!
