I think you've missed the point. Look at the FAQ where it is explianed in some detail how

It's illegal to obscure your number plate
Cameras won't read an obscured number plate
Speeding fines are 60 quid plus 3 points
An obscure number plate is 30 quid and no points

But they emphasise that you should be careful not to obscure your number plate.

I'm not saying how I know, but you need to muddy your number plate a hell of a lot to fool an ANPR camera, to the point of putting lumps of mud on. As soon as the IR flash goes off the plates shine on through.  So these muppets will not only be acting illegaly but they'll probably be wasting their time. :P

drmike:
Now that is seriously interesting.

How does IR cope with clay based mud though? There's mud and mud!

I would be genuinly interested to know how IR can deal with mud of different types. A feel a google session coming on!

So all I need to do is market some kind of IR reflecting stick-on film (blocking 850nm and above) which is transparent to visible wavelengths.

I could make a fortune!

Something like these 3M window films would block IR
