I've noticed recently that some odd looking cameras have started
popping up on gantries around london. I've seen them on the A406, A12
and A13 so far. They/re quite small, round and theres usually 4 or 5
of them mounted horizontally on a bar across the carraigeway. Are
these some sort of number plate recognition system?

Number plate and face recognition according to the press. A more
permanent version of the slew of unmarked white vans with things on
tripods on over bridges during the party conference season I guess.
