Door frame Metal detector

A door frame metal detector is a walk-through security screening device designed to detect metallic objects on a person's body or within their belongings. Resembling a standard doorway, it creates a precise electromagnetic field. When a person passes through, any ferrous or non-ferrous metal disrupts this field, triggering an immediate audible and visual alarm.

These systems are highly sensitive and can be calibrated to ignore very small items like buttons or zippers, focusing on potential threats such as weapons or contraband. They are a cornerstone of physical security, providing a robust, non-intrusive first line of defense. Commonly deployed at airports, government buildings, courthouses, schools, and event venues, they ensure a rapid and efficient screening process for high-volume pedestrian traffic, enhancing safety by deterring and identifying concealed metallic threats.
