Nicely hiden cam by the tire

Infrared LED`s with two camera`s no flash will be seen!

That's where something like this would come in handy:

Put that next to your plate and no camera will be able to read it. Cool thing is it's invisable to the naked eye, only the camera can see it. :)

If you can't fight them, Blind them! :)
