I had presumed it was a form of anti-speed camera type plate

+1, thought the same.

Haven't seen much of it, though.

Yeah, that may actually work too. Normal plates have the black text/numbers in a matt finish while the white area around has a highly reflective finish. This creates an area of high contrast (ie the numbers) which makes number recognition much easier.

Its possible the blue layer equalises the effective contrast across the plate, making it hard for ANPR to accurately isolate the numbers. The system may also not like the uniform blue tint either.

Id love to have access to the ANPR system to test all these theories out.

As far as I know it's simply a protective cover similar to the type that covers most displays on new electronic equipment. While it is blue, I doubt that it's enough to disturb ANPR systems but as Matt said - it would be nice to have access to know for sure.

Maybe someone who has yet to remove the blue cover could tell us if they receive toll charges or speeding fines............somehow I doubt it's that simple.

Seriously doubt it's that simple to avoid ANPR cameras.

It would be far too easy, and even if you were stopped by a guard you could just say you only put new plates on yesterday and forgot to take off the film.

It'd be easy to filter out.

You can still tell black from the blue fields around it.

Again, ties into the ever growing theory that most drivers are idiots.

Seeing that blue film is a pet hate.

Why people cannot remove it is beyond me and to think it will stop speed camera, anpr getting you is mind boggling.

Look at the drivers next time. These guys are just on step ahead of an amoeba.

it is very easy to do, if you have some spare time and some money :rolleyes:

Calm down there lads. Are we not all getting a bit carried away. Does a blue film over a number plate actually harm anyone or matter to anybody else. Who Cares.
Maybe those who have the plates dont actually know that the film peels off, or maybe they actually collected their new car with the film still on it.
Either way seems like were on a slow day and posting only for that reason

On par with the idiots that put there L plates on back to front, or even worse the one that stick them ob the paintwork.

Also another thing that annoys me is the big stickers dealers are putting on the back of new cars advertising themselves, saw one yesterday that was huge, If I was buying from a dealer and turned up to collect it and they had an advertisement for themselves on the back I'd tell them to stick it,

+1 that the people don't cop it.

Or maybe some people think it looks good and or suits their Dublin reg.

Whatever about ANPR, when Gardai are using a laser gun (and I'm subject to correction) I believe the guidelines are to aim the beam at front number plates (if possible) as they are more reflective than the rest of the vehicle. The more reflective or shiny something is the more accurate the reading. The beam can reflect back (better or more efficiently) without distortion. So in theory a dirty or matt finish or something might give you a moment more time (.25 or .5 of a second) to hit the brakes and reduce speed slightly before they get a reading.

I personally think the blue looks good than the boring old black on white. Its probably illegal, but its not severe enough to cause any harm to anyone, and when I got the plates done in Jan, I left it on till I got home that night. Its definitely not as daft as a bazillion other things you see on the road - from fog lights where there is no fog, over sized spoilers, cheap flame or sport stickers / paint job, overly blue headlights, drain pipe exhausts etc to psychopaths who should never be allowed near a car etc..!

demac

I'm with positron on this. It's something a little different from the boring black on white. I've left the film on my plates and will eventually remove it. I've been waved through a few garda checkpoints and nothing has ever been said. I also do not expect it to "save" me from the speed cameras.

We're not all idoits ppl !

it's just the blue protective film that comes with all perspex, most people probably don't notice it. odd thing to annoy people.

What does it do to reflectivity at night?

You realise that lasers travel at the speed of light?

My non-technical eyes says its exactly the same with or without the film. Then again, how long is a piece of string etc..!

Yes but the person using it doesn't. It is only as good as their aim and they often do not take a reading straight away but as a vehicle approaches (second or two later).
