New Heathrow Express Advance fares

When I was at Heathrow T2 last week I was surprised to see that there was a CCTV camera for *every* space in the car park. One of the side effects (although they could do it with less intrusive technology) was that empty spaces had a green light above them, so you could see from afar, down each aisle, whether or not there was somewhere to park. That's "sensor parking". The camera is probably just detecting presence, rather than being recorded. There's a similar one in Milton Keynes, the sensors are just metal detectors and feed back (a) which spaces are free, and (b) direct wardens to overstayers. Trains could have some system linked to checking if a seat was occupied (although their are issues if people put bags on seats) and have coloured lights above indicating (eg) Green for empty, Orange for empty-but reserved, and nothing for occupied. Or maybe red for occupied and in the foreseeable future a reservation pending. Would be an option I suppose. Neil -- Neil Williams Put my first name before the @ to reply. |

Yeah, right. Not all CCTV cameras record things. To suggest they do is paranoia. They may not even be cameras, they may simply be ANPR or presence detection. Neil -- Neil Williams Put my first name before the @ to reply. |

ANPR requires a camera. Sorry, I meant that the only output from the camera was ANPR data, not surveillance. A lens with LEDs (infra red I presume) around it. Looks like a camera, then. Though it is by no means clear what is done with the data from the camera; possibly nothing other than checking whether it sees a car or a piece of tarmac. Germany, for instance, is not a CCTV loving country, and while cameras are usually provided for DOO train dispatch they are often not used for surveillance.

Germany, for instance, is not a CCTV loving country, and while cameras are usually provided for DOO train dispatch they are often not used for surveillance. Germany is a different country with a very different approach to privacy (and also a different approach to arming their police, although I don't claim there's any direct correlation). -- Roland Perry |

I would strongly suspect they won't do this, and there will be a completely separate, regular CCTV system for that purpose. Germany is a different country with a very different approach to privacy (and also a different approach to arming their police, although I don't claim there's any direct correlation). This is true.

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. -- Spud |
