Cameras for best AI performance
Ben suggested that for optimal AI I look for 8 MP, P-Iris, and autofocus (as well as careful attention to placement and lighting). He advised me not to worry too much about low-light color capability in comparison since IR B&W does so well.
8MP/P-Iris/autofocus cameras seem rather few and far between, and my highly experienced preferred installer has questioned how important the P-Iris feature really is.
(As an aside, he is also biased against Hikvision, which does have such cameras at a reasonable price, due to disturbing human rights allegations, e.g. Uyghur-specific face detection for the Chinese government's program to control ethnic minorities. He's also concerned about the phone-home problem with the Chinese-government affiliated companies such as Hikvision, though that we can easily solve that I think with simple network segregation.)
I'm curious how important P-Iris and autofocus are to SecuritySpy's AI performance as a practical matter. I'm strongly leaning toward following Ben's advice based on his experience, but it does complicate camera selection.
