Safe Speed Program -
Speed Camera Operation

How does the camera know when a violation has occurred?

A speed measuring device is aimed across the road and determines the speed of the vehicles that pass through it.  If the detected speed is higher than the established speed threshold set by the certified operator, a digital image of the vehicle is recorded.

How do I know the camera was functioning properly at the time of my violation?

The entire system undergoes a thorough self-check prior to and at the end of each deployment.  The results of the testing are captured in the computer and are recorded.  The cameras will only operate if all the components are working properly and will automatically shut down in the event an error is detected.  The equipment must then be re-tested and manually re-started before recording additional images.

When and how often is the automated speed enforcement system calibrated?

Maryland law requires the speed detection equipment to undergo an annual calibration check performed by an independent calibration laboratory. 

Additionally, Maryland law requires the system operator to complete a setup log that states the date and time when, and the location where the system was set up and that the operator successfully performed, and the device passed, manufacturer-specified self-tests before producing a recorded image.  The setup log and these self-testing procedures are completed prior to a deployment ending and any citations being issued.

No school zone speed control system will be used for enforcement unless the operator has completed all required setup logs, the system has passed all manufacturer-specified self-tests, and the system is operating properly. The steps for self-test include tuning fork test for radar unit, a test photo, and a manufacturer self-test sequence.

Will the program be audited?

Yes.  On a regular basis, the Bowie Police Department or their representative will perform audits of the automated speed enforcement operator and equipment.
