I like how this venture Canadian company, reinvents and uses the old radar technology for detection of concealed weapons. I think the possibilities of its technology are endless, especially when it comes to security around schools, Airports and businesses. Maybe it is a diamond in the rough waiting to be discovered. https://patriot1tech.com/news/videos/ https://patriot1tech.com/news/who-o...stem-shotspotter-or-patriot-one-technologies/
