database
otherwise
er, *ALL* cars passing an ANPR are looked up and the date/time/location information stored against each number plate.
registration
those two
You only need an actual time for fairly adjacent cameras. Any sensible scroate will pick the registration of the same make/model/colour of their car that they have seen around the area a few times. Scroat does not know when the genuine registration goes off to it's Auntie Jeans in Abredeen. Seen in the Home Counties then
4 hours later in Aberdeen...
I doubt there is a "wanted" list just a flag (or set of flags) on the registration marks record.
They collect the data on all vehicles passing ANPR cameras. How often you pass such a camera and thus have your position both geographic and temporal recorded is variable.
The computer can very simply compare current position and last position and set a flag on that registrations record.
No one is suggesting that but the status of the "clone" flag can be sent back to the traffic cops with their live mobile ANPR camera just like they get told of "no tax", "no insurance", "no MOT", "Wanted", "Violence", "Firearms", etc etc...
I wouldn't like to bet on it.
You mean you haven't spotted 'em, I don't think there are any within
15 miles of here but I'm not betting on that either.Any decent sized town will have ANPR cameras, they may well be associated with other street furniture like traffic lights. They don't have to be huge grey and yellow things like GATSOs or the bright yellow arms holding average speed cameras, those are deliberately visible. ANPR is decidedly more covert.
Quick google Gruaniad story from 2012 says 5,000 roadside cameras. There will be more by now... How many and where appears to be a state secret.
