Red Light Camera Demo
This video shows a controlled demonstration of a vehicle running a red light, with officers and traffic management equipment off screen.
If you will look at the top right hand portion of the video, you will see that the light changes from yellow to red prior to the arrival of the test vehicle. Not shown are still photos taken at the same time as the video which document the driver and passenger as well as license plates. The citing officer will arrive at court with a video such as this, as well as the associated still shots.
