A red light camera is a traffic camera which captures an image of a vehicle moving through a signalized intersection traffic moving in the direction of that vehicle has a red signal. Red light cameras enforce traffic laws and deter violation to traffic laws by photographing vehicles passing through signalized intersections illegally. Red light cameras automatically photograph vehicles whose drivers run red lights. The cameras are connected to the traffic signal and to sensors that monitor traffic flow just before the crosswalk or stop line. The system continuously monitors the traffic signal, and the camera captures any vehicle that doesn't stop during the red phase. Many red light camera programs provide motorists with grace periods of up to half a second after the light switches to red.
