are of course cameras on (at least some) buses which record the road
ahead. I've wondered whether the driver presses a button or something
to mark a particular point on the recording when they witnessed an
infringement? Perhaps not, as it'd distract them from driving (unless
they were stationary and held up behind a parked car, for instance).

No idea how they're stopped and started, but they admit to having 1045
cameras in this document:

I don't think it is a particular secret that the bus mounted cameras,
or rather the recorders on the buses, switch and off automatically as
the bus enters and leaves the bus lane. It therefore records the whole
bus lane regardless of whether there are any infringements. The
positions of the bus lanes are programmed into the recorder and the
system knows where the bus is by using the on board tracking system
from the roadside beacons that are already in place on the vehicle for
Countdown and other operational purposes.

Thanks, that makes perfect sense. I had this crazy vision of bus
drivers quickly pressing some red button to either start the recording
or mark a point in it, for which they would be rewarded each time a
ticket was issued - a sort of performance-related-bonus! I'm glad to
hear that my highly improbable scenario doesn't actually happen!
(Though the banter in the bus garage tearoom would have been enlivened
by this... "I got 10 cars today"... "Well I got 15"... there could
even have been a sweepstake!)
