Have you ever seen IRR through NV?

It's just black.

So probably, as big black, army motorbike shaped blobs. With the people on them glowing like casper.

For that to happen you'd have to be wearing IR clothing boot's and helmet.

No I'm only kidding, I don't know the answer to be honest.

Try it and let us know.

I reckon it would get a return. Most things give off IRR, so a big black blob would stand out.

Th software probably works on looking for a significant change in the image, and changing a mixed image for a black blob would trigger it.

In the sniper course, you are shown how to use black and nasty (Gaffa Tape) to make you're non reflective black blob combats look like a tree, or other natural vegetation. Like DPM in Night vision.

Shame I'm selling my NV scope or I'd show you some time.

This is my do-it-all vehicle in and around London...I think you'd be able to get a reading off it from as far as...oh, the moon?

Go have a play yourself then, the older stuff due to the lesser line resolution and lack of sensitivity (not that they are bad, just not cutting adge anymore) actually shows up the differences with the IRR stuff even more.

No, I meant use your NV to simulate the effects of differing IRR patterns, then you will a better idea...

Hang on, if they ARE using IR camera, why not just mount a couple of high intensity IR LED's in your number plate light mount, alongside the visible light.

Then when they look at the IR image, all they see is white light, obscuring the plate!!!!

I'm a genius.

Want one!!!

Would be perfect for getting to work!

Just dont get too carried away, the armoured omegas are interesting!

P.S.

As an electro-optics specialist, none of the speed camera ideas work!

However, an active IR jammer would!
Not as far fetched as you would think. However it would be a COC violation for me explain

£46,000 + VAT for the Mondeo ............. Gotta be really kean there?...

How do the cameras work then?

For example, if I am looking at something in the IR spectrum and someone shines an IR illuminator at me, I see blinding white light, and my NV auto cuts out.

If I shine that at close distance onto something, it ends up just being white light, obscuring any detials of whats behind it.

So if the cameras were just pure IR spectrum, then you would expect that a couple of high intensity Infra Red LED's would 'white out' and thus could be used to obscure the plate.

I take it that this is not the case though?

If you are talking about fixed cameras they use radar and  in the new blue ones (TRUVELO), Speed measurement is carried out using two independent pairs of sub-surface piezo sensors. No radar.

The flash is IR on the forward facing TRUVELOS but is normal white light on the GATSO's. The mobile vans are normal video / still imaging.
You may only be able to defeat the flash in the IR spectrum but not the visable.
The photographic image may still be readable with negative reversal.  

For the Talivans (they terrorise motorists) they are using laser;
Range 1000M (weather limited) Measurement time 0.5 second!

There is no law as yet regarding the purchase of a Laser Jammer or the fitting of one on a motor vehicle. However, if you do, then this is the likely to happen:-

Northamptonshire police,  have had the laser camera equipment software modified to photograph any vehicle that throw up an error, any error. When the video is checked at the camera units base and an error is reported the event is logged as a warning flag on the PNC database (police database).

When another camera van operator takes his video back to base to check over, if he discovers an error he will check on the PNC database to see if there are any warning flags on that vehicle.

If there are no flags on the PNC for that car then one is added. If the PNC has a flag on it saying they have had a problem in the past they will investigate further.

Typically,  the car is taken to the police vehicle inspection unit.
The jammer is tested to see if it jams. The person is then arrested for "Perverting the course of Justice".

This offence is very serious and carries 7 years in Jail. It is normally used to deal with people that are caught out telling lies to get away with something or gain something without actually going to court and perjuring themselves in the witness box.

The fight is then on in court, so far the one case has been dropped by the CPS.
??Pending the proposed ban of all laser and radar detectors / jammers??

I knew all of the above.

But Andy seems to be sugessting there is a new type of camera.......

No, use your goggles and have a look, with other visible light (streetlights) it wont work.

Iv'e always wanted to know where i can get my hands on a Dennis fire engine!

..and a nice clear image of your number plate.

Forget the Dennis - get one of these!!
