Police cameras that record motorists’ movements must be more tightly regulated, Home Secretary Theresa May has ordered.
The 4,000-strong automatic number plate recognition (ANPR) network logs more than 10 million vehicles every day.
The government is to look at limiting access to the database of 7.6 billion images, details of number plates and the date, time and place of capture.
Privacy campaigners said restrictions on the ANPR network were long overdue.
The cameras capture the front of cars and photographs can include images of the driver and any passengers.
Ministers will consider how long these records can be held. The current limit is two years.
Mrs May says she wants proper accountability and safeguards in the use of this database.
. . .Campaign director Dylan Sharpe said the review was “long overdue”.
“ANPR gives the state the ability to track every car journey we make. It is about time that some restrictions were placed on the use of this intrusive technology.”
