speed camera
Roadside traffic watcher
A speed camera is a device that photographs vehicles exceeding the speed limit, capturing license plates to enable automatic ticketing.
Fixed cameras monitor specific locations; mobile units can be repositioned.
Drivers often warn each other about speed camera locations, and some navigation apps flag them: Slow down, there's a speed camera ahead.
