IMO embrace low frame rate. Better energy use if its AI based on the first place (cheaper, environment... more cycles for fancier effecs) THEN pair that with e-ink display (also good energy use), I'd go for old school charcoal style but color e-ink is a thing. e-ink with some additional effects could resemble a physical paper moreso then a LCD/LED and so would be less obnoxious in the darkness of night... AND this also could be a low key security camera.
