VACIS systems conduct scans on various vehicles such as cargo containers, trucks, railcars, buses, and passenger cars to assist authorities in detecting narcotics, weapons, nuclear materials, undeclared items, and other illegal goods at entry points, border crossings, military sites, and various checkpoints. Leidos stands out as a pioneering force in the realm of non-intrusive inspection technology, with their systems being deployed globally for both governmental and commercial entities since their introduction in 1999. Each VACIS system comes equipped with comprehensive installation, training, maintenance, and technical support. Designed with the shortest wheelbase and lightest weight in its class, these systems enhance maneuverability and handling, featuring an industrial chassis intended for firetruck operations. Additionally, they boast a global support network and a sophisticated high-energy imaging system capable of material discrimination. These advantages, coupled with advanced AI and machine learning capabilities, empower inspectors to efficiently and accurately identify weapons, contraband, undeclared cargo, and other prohibited items, significantly streamlining the inspection process. As a result, VACIS systems play a crucial role in enhancing security measures worldwide.
