A speed camera is a type of traffic enforcement device that is used to detect and record the speed of vehicles as they pass by. These cameras are typically placed in high-risk areas such as intersections, school zones, and freeways to monitor and enforce speed limits.
Speed cameras can use various technologies to capture the speed of vehicles, including radar, laser, and inductive loops. When a vehicle is detected exceeding the speed limit, the camera will capture photographic or video evidence of the vehicle and its license plate, which can then be used to issue a speeding ticket to the driver.
Speed cameras are widely used in many countries around the world as a means of promoting road safety and reducing the number of accidents caused by speeding. Critics argue that speed cameras are primarily used as revenue-generating devices rather than improving road safety.
