There are two cameras installed approximately 200 metres apart. Each camera photographs

every vehicle travelling in the bus lane. The CPU within each camera analyses every photo to

determine the vehicles registration plate number. Both cameras communicate to determine if a

photo of the same car has been taken by the first camera and then by the second camera. If this

occurs then the photos and registration number are stored on a hard disk within the first camera.

An RTA officer manually replaces the hard disks about once a week. At the RTA office the

contents of the hard disk is imported into the RTA database. Then each vehicles owner and

address is determined by querying the RTA database using the registration numbers. Finally fines

are generated and posted to vehicle owners.
