A sleepy Home Counties market town has become the first in Britain to have every car passing through it tracked by police cameras.
Royston, in Hertfordshire, has had a set of police cameras installed on every road leading in and out of it, recording the numberplate of every vehicle that passes them.
automatic number-plate recognition system will check the plates against
a variety of databases, studying them for links to crimes, and
insurance and tax records, and alerting police accordingly.
