Current Systems
Three camera types
- on-bus cameras
- static roadside sites
- CCTV systems
System Components
- wide-angle cameras
- close-up camera
- radio clock
- multiplexer
- video recorder
SLIDE 14
Current Systems – Bus Mounted Cameras
SLIDE 15
Mobile recording: moving along the lane
Context and close-up views are recorded continuously onto video tape
Time, beacon number, distance and other information are superimposed on the tape

System requirements
- Vehicle location to 10 metres
- False trigger rate <10%
- Evidence pack quality:
- Frame rate of 5fps
- Picture quality to be acceptable to the adjudication service
- Evidential security of data
SLIDE 39
DTES evidence pack
- Metadata
- automated back-office processing
- Close-up video
- ANPR trigger / IR illuminated / monochrome
- Context video
- wide angle / colour / pre- & post-trigger times configurable
- Packet size around 1.3Mb each
(5fps; 5s pre-; 5s post-trigger)

Further Development
The object of this phase is to test the response to the new technology at adjudication, prior to the main contract being let.
The aim is to eventually run dedicated enforcement vehicles from depots across London, fitted with radio gateways.
