What is DFMD?

A DFMD, or Door Frame Metal Detector, is a security screening device used to detect metal objects as people pass through it. It is commonly installed at entrances of airports, malls, offices, event venues, courts, and government buildings. The device works by generating an electromagnetic field inside the frame. When a person carrying metal passes through, the field is disturbed, and the system triggers an audio or visual alert.

DFMD scanners are very convenient security devices that allow you to detect weapons on a person without physical searches. Some of the higher scanner models are designed with multiple detectors and adjustable sensitivity options to counter the various ways people carry weapons or dangerous metallic items. These devices offer speed and efficiency in searching large numbers of people at commercial places, airports, industrial facilities, and more.
