A DFMD (Door Frame Metal Detector) is a security device used to detect metal objects carried by individuals as they pass through it. These machines are commonly found in airports, malls, offices, and high-security areas to prevent the unauthorized carrying of weapons or contraband. DFMDs function based on electromagnetic fields to identify metal objects.
Types of DFMD Machines
- Single-Zone DFMD:
- Detects the presence of metal anywhere within the detection zone.
- Does not indicate the exact location of the metal.
- Suitable for low-security environments.
- Multi-Zone DFMD:
- Divides the detection area into multiple zones (commonly 4, 6, 8, 18, or more zones).
- Indicates the specific height or section where metal is detected using lights or signals.
- Offers higher accuracy and is preferred in high-security areas.
- Portable DFMD:
- Lightweight and easy to transport.
- Often used in temporary security setups or events.
- Weatherproof DFMD:
- Designed for outdoor use.
- Resistant to environmental factors like rain, dust, and extreme temperatures.
- Advanced DFMD with AI Integration:
- Includes features like people counting, threat level analysis, and automatic adjustments for varying environments.
- Can integrate with other security systems like CCTV and biometric devices.
