Flock ALPR Cameras

Infrared LEDs are a respectable camera countermeasure.

Cops are wise to the coatings and film you can put over a license plate. In many states, you can get busted for doing that. You dont own the plate. The state does. So they can declare you may not modify it in any way.

But casting a halo of light on your tag has not been tested in the courts and since it is invisible to the naked eye, your chances of this being detected are pretty slim. Naturally, this works better at night. But I think (not sure) if you flood the plate with enough IR light, it may prevent a camera from seeing the number clearly.

Obscuring the entire car to prevent it from make and model being recorded or identified? Possible but not practical. Theoretically, it could be done.

Speed and toll cams are more susceptible to being blocked by IR light. Less expensive cameras that rely on visible light to capture an image are not as dramatically affected.

From what I have read, the Flock ALPR cameras have a daytime color camera, and a separate nighttime IR camera.
If you surrounded your license plate frame with IR LED's, it would bloom the nighttime image, but not affect the daytime color camera. AFAIK, no one is marketing such a frame yet.

There are all sorts of gadgets for sale from adhesive letters that are not supposed to be visible to the camera, to matte sprays that are supposed to kill the reflectivity of the plate, to Fresnel lenses that distort the image, to magnetic leaves that fall off with the press of a button. All fall under the heading of "obscuring" the plate. Illegal in most states.
There are several youtube videos testing the effectiveness of these devices and they all fail in one way or another.
There is even a "James Bond" license plate flipper that with the press of a button flips the tag over to display either nothing, or another plate on the other side. Fine I supoose if you ride with a navigator that can map the camera locations so you can flip the plate until you are past the camera. Great until that one time an unmarked car is behind you when you flip.

It would seem that the only practical way to protect your privacy from these would require the trouble and expense of registering the car to an out of state LLC you create for the purpose. Then the system would not flag the image for "no tag" or "unable to read" time after time but return a legit registration that is for this purpose, anonymous.
 
Didn't they say the system couldn't create a map of your travels? Maybe not automatically, but if it gives you all the waypoints, and all the cops have to do then is connect the dots, what's they difference? :confused:
