Security Metal Detector

A security metal detector is used for detecting metal objects, including knives, tools, guns and other metallic items, which people might carry around at public places. The two main types of security detectors are walk-through detector and handheld detectors. Both are implemented to use at the security gate by guards. A handheld metal detector is swept around the body surface of people while in a walk-through metal detector, people pass through a tunnel. 

A security metal detector is capable of detecting smaller metallic objects to aid in security check-ups in transportation hubs (airports, railways, metro), law enforcement, event places, public places (malls, clubs, etc), schools and building security, mail screening device, cargo screening, liquid explosive detection etc.
