A speed camera is a device used to monitor and enforce traffic speed limits. It captures images of vehicles that exceed the designated speed, allowing law enforcement to issue fines to the offending drivers. These cameras can be stationary or mobile and are often placed in areas where speeding is a common issue. Speed cameras operate using radar or laser technology to measure the speed of passing vehicles. When a vehicle is detected speeding, the camera takes a photograph of the license plate, which is then used to identify the owner. This system aims to improve road safety and reduce accidents caused by speeding.
