DFMD - Door Frame Metal Detector | Walk Through Metal Detector - A gatelike structure through which a person passes, used in detecting concealed weapons such as guns and knives.
A metal detector is an electronic instrument that detects the presence of metal. Metal detectors are useful for finding metal hidden within objects, or metal objects buried underground. A Door Frame Metal Detector (DFMD) as the name suggests is a metal detector fitted in a door to detect metal that may be hidden on the body of the person passing through this door. This is also known as a “walk-through” metal detector. These are used for security screening at access points in prisons, courthouses, and at airports to detect concealed metal weapons on a person’s body.
