ANPR cameras- are they everywhere and logging everyone?

textbook

If a guy was going to drive a couple of miles through different residential places over some main roads would their car be logged. Someone told me that if they were up to no good. Would the cameras log his movements? What do the cameras look like and where typically are they located?

If the guy was going to go on his biycle would that also be recorded, or is it just number plates which are photographed and recorded

Why are you asking?

System

ANPR -Automatic Number plate recognition

How could it possibly record you on a bike ??

Although on a bike or walking you could be caught on CCTV. Although the local authority (police) CCTV doesn't normally cover residential only areas, many people now have their own CCTV cameras and you wouldn't necessarily recognise them.


Haven't you already asked about being caught on CCTV?


Now ANPR.


Why??

Anything can be recorded on cameras.
ANPR cameras are specifically designed and setup for number plate recognition (hence the name), but are basically just normal cameras linked to a suitable back end system.

Normal CCTV cameras will record like a camcorder, or even in TV quality, at anything up to to the full 25fps at 1080p (or higher).

As for what they can look like, virtually anything.
There are obvious ones, but there are dome types, turret types, bullet types (like a coke can with a lens), but also far more discrete types.
The big ones that are obvious might well be dummies to draw your attention away from the real ones.
Doe a google for CCTV camera pictures...

The better home CCTV cameras can be set to be motion activated (they'll only record for a few seconds before, during and after movement is picked up), they can even be set to do ANPR when paired with the right recorder.

Whether you'd be picked up would depend entirely on the quality of the camera and how it was positioned in relation to the road.
Most private ones will be set to cover houses and drives so picking up the road is incidental (but depending on the setup could potentially get a picture good enough for tracking).

Maybe folk are being a little unkind. This could be research for someone's first crime novel.

(I only said "could be" :cool:)

Does ANPR mean filming a car reg and then having the technology to read that number and send it to a computer to be identified? And do they do this with every car (the crime ANPR ones)?


If any car passed one (there would certainly be one in a town centre, wouldn't there?) Would that information definitely be retrievable from days before?

How does the camera know in advance that movement will take place?

They're usually recording on a continuous basis but the camera will discard it after a few seconds unless there is a change in the picture, in which case it'll mark it and keep it until the recording medium is full and it either gives you a message asking for instructions, or automatically starts recording over the earliest kept recordings.

It's one of the nice things about modern CCTV systems, you're not having to record everything and change the media every X hours, but you can say put an SD card or HDD that might have enough space for 24 hours worth of recordings, and the recorder can decide what should be kept as it goes (so that 24 hours worth of space might be enough to record everything that happens for a week or more as it's discarding worthless recordings and reusing the space saved as it goes).

The same sort of system is in use with dash cams, (and even aircraft data recorders), they're recording all the time, but discard anything after a set period unless it's tagged by either the user or the automatic system (say g-forces go over a set limit).
