    This approach only works in daylight with cameras that rely on colour only. Infrared spectrum cameras such as what Australia uses on mobile phone traffic cameras are much harder to deal with. Patterns don’t cut it and it’s a huge part of military research into hiding vehicles from infrared spotters.

    Disabling the cameras entirely is much more effective.

      For IR you can feasibly run IR dazzle lights all over whatever you want to mask, including your face.

        No need, you can just use an IR spotlight to blind the camera. Unlike the military you’re not trying to hide the vehicle.

        But either way you’re actively trying to avoid being picked up by speed cameras so you get a fine.

        Not really. We don’t have materials that absorb or reflect infrared light. It’s one of the reasons it’s hard to beat inferred-guided (heat seeking) missiles, the only real solution is to drop something hotter than your plane, aka a flare.

        So… get ready for a new era of commercial automotive flares I guess?

          You are mixing different types of IR and on top are wrong for both cases too. We have materials for both NIR and thermal IR that absorb or reflect them.

            I’ve been wrong before, this wouldn’t be the first time. But what part of it was wrong? Genuinely, can you clear it up?

            As far as absorbing IR light, I’m not even sure how that would work, wouldn’t it just be emitted again as heat?

      Dumb question I have no idea how infrared light works and cameras. But what if my license plate was just constantly firing infrared light to counter act or “blind” the cameras?

      I wonder if those cameras stop working if you have the new IR blocking window tint that keeps the suns heat out but are otherwise clear. Would the camera just not be able to see inside the car at all?
