Recently my city has decided they need to make even more money and installed this companies hardware. They have installed the red light/speeding camera duo. I understand how the red light cameras work with sensors in the pavement but I am wondering how speed is measured unless it is with the same sensors. I cannot pick up anything with my late model V1. A retired police officer I know told me they are having big problems getting speed sensing to work and stated they might never. By the way he hates all this crap too.
