The bus has an onboard HDD recorder which has capacity to hold footage for
around a month or so. The way it usually works (or did with us) is that
under normal circumstances, these are recording all the time that the bus
is active, from the moment the engine is started to a preset period (a
couple of hours or so) after it is switched off.

When the bus returns to garage at the end of the day, any incidents that
have been requested will be downloaded to the server. The whole of the
contents of the buses' HDD's will not be downloaded, this would just be a
waste of time, as for 99% of the time nothing important is happening. You
only need to download what you need to investigate any particular incident
that has been reported. If the bus happens to be in the garage, then it's
usually quite easy (I say usually, as sod's law says the equipment on the
bus will have failed when you really need something and the police are
standing next to you waiting..!) to download what is needed and put it on
a DVD or whatever. If it's out on the road, you generally have to wait
until it's back, hence it isn't possible to get instant access.


very useful, but

I don't know who saw the program - no one has commented,

though (with exception of the previously referred to police incident) most
of the incidents highlighted were office staff (or more likely now,
automated systems) determining that particular Oyster cards as suspected of
being used to travel long, or dumbelling. Historic CCTV data (some of which
was from bus journeys) was used to capture images of the suspected
miscreant. Thus the actual CCTV footage viewed could be weeks old.

RPIs were then show on the lookout for that person the next time they went
through a barrier at the expected time (as you might imagine, not with 100%
success)

For the purpose of a specific police operation, then they would follow a
bus in another vehicle and link directly to it, in this situation they
would be able to view the cameras live without being on the bus.

The TV incident was "immediate"
