How the Cameras Work
Traffic Signal Timing & Camera Function
Traffic signals are timed by traffic engineers through careful study of each individual intersection using national recognized procedures.
Red light safety cameras monitor intersection approaches through advanced detection and imaging technology. The safety cameras only photograph a vehicle if it enters the intersection after the light has turned red. A second photograph is taken as the vehicle progresses through the intersection. In addition to still photographs, a video of the violation is taken as well.
Yellow vs. Red
Vehicles that enter an intersection on a yellow light are not photographed even if they are still in the intersection when the light changes to red. The technology is designed to record motorists as they intentionally enter an intersection after the signal turns red.
Information Recorded for Notice of Violation
The camera photographs the vehicle from the rear, not the driver. The camera records the:
- Lane number
- Speed of the vehicle
