Speed cameras are devices used to monitor and enforce speed limits on roads. They capture images of vehicles that exceed the designated speed, allowing law enforcement to issue fines to speeding drivers. These cameras can be stationary or mobile, and they help improve road safety by discouraging excessive speeding. Typically, speed cameras use radar or laser technology to measure a vehicle's speed. 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 reduce accidents and promote safer driving habits among motorists.
