Radar warning devices never made it big in Europe.
Mostly due to the many different
frequencies used by the radar devices. Sometimes
instead of radar time measurement between
two thin rubberhoses on the street or between
two lightbeams is used to trigger the cameras.
Hard to beat.
What we do here is replace the rear numberplate
fixing screws by two strong infrared leds.
Those blind the cameras in a way that in court
the picture has no value as proof. Its not yet illegal.

Bullet proof or not, cameras mounted on
lamp posts and traffic lights get stolen regularly.
Wonder what make it is?
