A [[red light camera]] is a traffic camera that takes an image of a vehicle that goes through an intersection where the light is red. The system continuously monitors the traffic signal and the camera is triggered by any vehicle entering the intersection above a preset minimum speed and following a specified time after the signal has turned red.<ref name=Baratian>{{cite journal |last1=Baratian-Ghorghi |first1=Fatemeh |last2=Zhou |first2=Huaguo |last3=Wasilefsky |first3=Isaac |year=2015 |title=Effect of Red-Light Cameras on Capacity of Signalized Intersections |journal=Journal of Transportation Engineering |volume=142 |page=04015035 |doi=10.1061/(ASCE)TE.1943-5436.0000804 }}</ref>
