Do the Congestion Zone cameras in London take pictures at times other

I was discussing with someone who felt they might be left switched on
and recording to keep an eye on criminal, terrorists, stolen cars,
etc.

Depends what the CCTV license states the purpose is for.

If the license (or whatever it's called) states that it's for traffic
charging only, then they can't use it for ANPR etc.

Wanna bet? I'm sure if the police wanted to know who travelled past one
of the cameras at midnight on saturday, they'd be able to get that
information. In the same way as CCTV cameas at petrol stations can be
linked to the national ANPR database. There are no places to hide in
this supposedly free country.
