It's fundamentally a security camera, for many people. People buy them to see what's going on, record crimes for reporting, and to feel safer. I think there's significant overlap in people who want to feel safer and people being ok with the police being able to look through their cameras, since being able to record events, for the police, was part of the motivation for the purchase of a security camera. My frail elderly grandpa, who has seen his neighborhood go to shit with the reduced police funding, would definitely see this as a "nice feature".
