We had a possible breakin on my street, and police noticed my doorbell camera. They politely asked if I could check whether it picked something up, and I showed him a picture possibility (complainants said oh yeah that was us).
I was ok with it because it was a request, the cam only shows public areas, and it never left my control. I don’t know what would have happened if it went anywhere, but I could have said no, and I could have said nothing was picked up. This was all reasonable cooperation with no overreach or privacy invasion
