can we have anpr in our cars

[eskidavies73]

anyone know what hardware,software,needed to put an anpr system in your car ie.laptop camera so you can store unmarked police number plates to give you warning if they behind you or in front just so you dont do nothing stupid.not that you would anyway,BUT.

You can get hold of a cheap ANPR camera for about £300 or a full specs style one for a couple of grand...all you'd need then was a way of linking the output to a simple database you were keeping of specific vehicle registrations linked to some electronics to flag up a big red "oh no it's the rozzers" sign in your car somewhere when you got a match.

But before you start thinking it's actually worth considering, the effective range of most ANPR is about 10-30 metres. If you're misbehaving in a car, finding out there's a copper less than 30 metres from you isn't going to save you. If you're doing 100 and the copper is at 70, in the second it's taken your cobbled together ANPR to spot him, you've already travelled 13 of those 30 meters...

Eyes, ears and common sense is a lot more cost effective

HTH

You would need everyone to have ANPR in their cars, and for all the cars to communicate (say over CMDA) where they saw said rozzer, calculated by their GPS when they passed you.

Hmm, not a bad idea for an Android App...

Why is that? I'd naively assume that with a good enough resolution camera you could grab plates at a large distance.

yeah them army drones got cameras that can see the colour of your eyes from a few miles away up in the air so im sure theres somthing out there not as good obviously but half tidy

It's a lot of £60 fines you'd have to dodge to pay it back

But if your about to misbehave drive within your and the cars limits, it might be handy to know the cars around are not unmarked

Does anyone know where/if a list of unmarked police car number plates is available anywhere?

Remember of course that ANPR is only 90% accurate/successful, and thats the suppliers own figures, once you take into account all the different variables (lighting/angles/blurring/weather/plate defects etc...) im guessing the 90% drops even further.

My and my mate have tried, on several attempts, with various cars, to 'trigger' some mobile ANPR cameras on Traffic cars, all of which have failed (the cars show up as no insurance/tax/MOT), which further shows its far from a perfect system.

[hairykrishna]

Playing around with the freely available ANPR codes and a reasonable but cheap camera suggests it's an idea with legs though. A database of number plates is somewhat elusive unfortunately.
