"Big Brother" Strikes Again

That's why the dual action sander idea is best. When vibrator is off, the plate looks perfectly normal to the human eye. I didn't actually mean to use a real dual action sander, just something that will move the plate up and down and sideways at a high rate of speed making the plate letters/numbers a "blur" to a camera. It only has to move 1/8"-1/4" in each direction to make the letters/numbers blurry.
If the image is blurred in the traffic camera, they will know that somehow the plate has been modified. Also at the high speed the cameras take photos at, you couldn’t make it move fast enough to blur anyway. It would still be completely readable.
