City and county police are automatically running checks on every license plate that they see, Ted Strong writes in the Daily Progress. Each department has a single camera rig that’s attached to a police car—it detects the numbers on each and every license plate that’s within the cameras’ range and checks to see if it’s in their database of wanted vehicles. The city started using the system this summer, the county earlier this month. An electronic log of every license plate spotted by the system is retained—the city keeps the data for three months, the county for two. The system doesn’t scan for plates with expired inspections or registrations, for lack of a database to interface with.
