Chiltern Transport Consortium (CTC) has selected APD's Artemis telematics.
The consortium provides a cross-border shared service which attends to the fleet requirements of Bedfordshire Police, Civil Nuclear Constabulary, Hertfordshire Constabulary and Thames Valley Police.
Artemis will be fitted across the Thames Valley, Bedfordshire, Hertfordshire and Hampshire fleets.
This builds on current Artemis roll-outs at Northamptonshire Police, Nottinghamshire Police and Avon & Somerset Constabulary.
Artemis's reporting delivers detailed information on resource location, how the vehicle is driven, the identity of the driver and the condition of the vehicle.
It also acts as an incident data recorder, complemented by a collision data analysis software package.
Sam Sloan, head of Chiltern Transport Consortium, said: “Having looked at other solutions in the market, Artemis is comprehensive as a package and therefore better meets the requirements of senior police stakeholders."
