The request was successful.

Dear National Policing Improvement Agency,

I write concerning the National ANPR Data Centre (NADC) operated by the NPIA.

It is my understanding that an ANPR 'read' is a capture of the VRM and an image of the vehicle as it pases the camera. It is also my understanding that these reads are saved in a central repository and then transmitted to the NADC for storage in a database.

My questions are as follows:

How many fixed cameras feed information into the NADC database
Which organisations (Highways Agency, Police Forces, etc) supply ANPR read data to the NADC
Which organisations (Highways Agency, private companies, etc) allow their cameras to be tasked for the purposes of providing data for the NADC database.
How many 'read' hits are there. For example, how entries on the NADC's database are there of a car passing an ANPR camera site.
How long is ANPR read data routinely recorded for.

Yours faithfully,

HMP Britain

The Police ANPR database stores location of motorists... 7.6 billion times. Automatic Number Plate Recognition (ANPR) is a system whereby car numberplates are read as they pass a camera. The technology captures the number plate itself as a string (eg. X34 TVF) and an image. This comprises a 'read' and is then sent to the National Police Improvement Agency's (NPIA) National ANPR Data Centre (NADC) who store it on a database. An internal NPIA document confirms the database stores the data, time, location and images (PDF:
