Several months ago I made contact with a designer who had developed a vehicle speed camera and recorder that was based on Rasberry Pi in conjunction with a radar or lidar chip module. He was marketing this in the form of kit modules or as a complete device. He was ready to sell to me, but I had other projects ahead of this one (I always have far too many). Of course, now that I am ready to pursue this, I cannot find any contact information for him; I don't know if this was by email, on a dedicated forum, or in a FB group. Does the system description seem familiar to anyone here, and, if so would you be able to furnish a link or other information that might allow me to re-establish contact? Thanks in advance.
