Door Frame Metal Detector (DFMD) is a highly efficient security system designed for detecting metallic objects on individuals at entry points such as airports, offices, factories, and public venues.

It is a microcontroller-based system with an LCD display and keypad controls for easy configuration. The detector supports multiple zone detection (single to 9 zones), ensuring precise identification of metal location with high sensitivity and stability.

Key features include LED bar graph indication, adjustable sensitivity (0–255), audio alerts, IR sensors, and intelligent person counter. It also offers battery backup up to 8–10 hours, easy installation, and robust construction with FRP-coated frame for long-lasting performance.
