Evolv Express weapons detection

Evolv Express is an 'AI-based weapons screening system' that detects guns, knives, bombs and other concealed offensive weaponry at schools, hospitals, sports and entertainment venues, and public events.

Massachusetts-based Evolv Technology, which manufactures Evolv Express, says it uses 'proven' AI and machine learning to enable scanners to create unique 'signatures' of weapons that differentiate them from items such as computers or keys, thereby reducing manual checks and preventing long queues.
