Recoding a video stream from hundreds of cameras situated right next to
each other seems like overkill, even for the most paranoid.

I dare say they are just sensors.

Or alternatively they take a single static picture of cars parking.

A snapshot once a minute might be sufficient for the anti-terrorism
agenda.

And possibly a second one at the point that overstay is detected, for
enforcement purposes.

But probably nothing to do with any other form of surveillance.

I'm not sure what you mean by "existing" CCTV given that the T2 car
park is very new.

I mean a regular, separate CCTV system designed for surveillance, not
one designed to see if cars are there or not.

My view is that the very recently installed per-parking-space CCTV at
Heathrow T2 does both.
