They don't have to if it is a civil infraction. As I understand it, in many jurisdictions a camera ticket is a fine but no points. They just say "the owner of the car is responsible for who they allow to drive it" same as insurance liability.
Civil infractions are a giant end run around people's rights when you're talking about these size fines. They can't push it because if they do that risks ending the gravy train.
In Germany you get the fine with the photo where the face of the driver is very visible/recognizable 99% of the time. Even in villages have this type of cameras so they can't be expensive. Oh you get fined for driving without a seatbelt too.
