I agree with you that crimes like kidnappings would be solved faster but only for a short while, it is like fingerprinting today the criminals know to not leave them behind. The issue people have with this surveillance is the abuse that always happens by the government or private companies. For protecting your private property you should be able to film your property and provide the video to the police. For crime in public places maybe you can have cameras that are offline and that overwrite the video every n hours,if a crime happens then the police can ask a judge for a warrant only for the cameras in the locations connected to the crime, then using that warrant someone can get the physical key to access the cameras video, I think this system can help with crime and make the abuse harder, when I am thinking at abuse I am thinking at police or other employees checking on who they want, find all their movements, find who they talked to and politicians can abuse it to find dirt and blackmail their opponents, journalists and critics.
