No info about the tech in this article, but from the video I guess it's just a very long telephoto lens? No fancy letter-detection radar algorithms or anything

- sriram_malhar 6y agoIt is likely a more powerful LIDAR, a laser with a very narrow beam width (but weak enough to not affect eyesight). Combine this with retroreflective paint on the license/number plate to get both speed and the number. Here is some info about building a lidar detector. https://www.ibiblio.org/rdu/usenet-arc/sub00243/msg00000.html https://www.ibiblio.org/rdu/usenet-arc/sub00243/msg00000.htm...
