Digital Red Light & Speed Camera

Changeable operational parameters include:

This information is encrypted, protected with message authenticated codes, and then stored ready for subsequent transmissions to a central computer. A built in flash module permits operation at night and uses three flash tubes. This means that the time between shots will be a lot quicker than single operating flash units, as no time is required to recharge the flash tube in between violation images.

Digital cameras record data relating to the offence and save the information along with the images that are taken. This data will vary according to the specific type of enforcement system installed. Information recorded with violation images taken by the RedSpeed system include;

Three images are captured, the first is a zoom shot showing the vehicle number plate, the second is a wide angle image including make, model, colour of car and the offence data. The system then delays, for a period related to the vehicles speed, and captures a third frame, also a wide angle image showing the time delay between frames. The two wide-angle images can be used as evidence to show that the vehicle was moving at the time of the recording.

RedSpeed utilises all of the functions of the and systems, it is used at traffic light junctions to enforce traffic signals and speed limits. The system detects speed violations during the green and amber phases, and also detects red light violations.

RedSpeed operates using digital technology and therefore requires no film. Unmanned fixed equipment is installed at the roadside where traffic violations are automatically detected by the system using appropriate road sensors.
