A scanner is a security device used for detecting hidden objects like explosives, contraband material and smuggled goods in the human body, luggage and even under automobiles. It does primary scanning without causing any inconvenience to the public. If any suspicious thing is found in scanning, the security personnel can go for manual scanning of the luggage or human in question. Available in different sizes including handheld design for vehicle under-checking, this device is found everywhere including airports, metro stations and government establishments and parking areas. Easy-to-install and convenient-to-use, this device plays a crucial role in improving security in a restricted area.
