I'm not sure how the cameras used to take pictures of car license plates so that the driver can be identified and required to pay a toll for use of the road, is meaningfully different than a camera used to take pictures of car license plates (and other things in the scene) for the purpose of detecting crime. It's still the government running a camera in public to take pictures of things, including cars with clearly-visible license plates, and then knowing that the car was at a specific location at a specific time.
