First of all, you appear to be asking two different questions. In the case of the automatic light, the light is going on because of you. In other words, you turned on a light, just like if you flipped the switch, so you are really asking if walking in the street counts as ????? or possibly ???? ???? ??? ???? ??? . In all the other cases, the melacha is a process set in place before shabbos; your being there does not influence the camera in any way.
I’ve learned these halachos, but not in any great depth, so I won’t say anything more even though there is no danger of anybody taking this as a psak.
