Our DFMD Products and Services in Bhiwadi
DFMD Supply and Installation
We supply door frame metal detectors designed for security screening at entry and exit points. Our team can guide you in choosing a suitable model according to the size of the premises, visitor movement and operational requirements.
Walk-through metal detectors are used to screen people without interrupting the movement of visitors. These systems can be installed at entrances to help security personnel monitor access more effectively.
Multi Zone DFMD Systems
Multi-zone metal detectors divide the detection area into separate zones. This can help security staff identify the approximate area where metal has been detected, supporting a more focused secondary screening process.
DFMD Maintenance and Repair
Security equipment needs regular checks to remain operational. We provide DFMD maintenance and repair services in Bhiwadi to help keep systems in working condition and reduce avoidable downtime.
Annual Maintenance Contracts
Our Annual Maintenance Contract (AMC) options are designed for organisations that need ongoing servicing and technical support for their DFMD equipment. Regular maintenance can help ensure the detector remains ready for day to day use.
DFMD Rental and Leasing Options
For temporary security arrangements, leasing or rental options can be useful for exhibitions, concerts, sports events, corporate functions and other short-term requirements. Contact our team to discuss availability and your specific requirement.
Choosing the Right DFMD for Your Location
Before selecting a door frame metal detector, it is important to consider:
The number of people expected to pass through the entrance
The level of screening required
Available installation space
Indoor or outdoor placement conditions
Requirement for zone-based detection
Need for service, maintenance and technical support
Whether the requirement is permanent or temporary
Our team can discuss these factors with you and recommend a suitable DFMD configuration for your site.

Comprehensive FAQs on Door Frame Metal Detectors (DFMD)
1. What is a Door Frame Metal Detector (DFMD)?
A Door Frame Metal Detector (DFMD), commonly referred to as a walk-through metal detector (WTMD), is an upright archway installed at building entrances and checkpoints. It automatically screens individuals passing through for concealed metallic items, including knives, firearms, tools, and unauthorized metallic hardware, without requiring immediate hands-on pat-downs.
2. How does a Door Frame Metal Detector work?
DFMDs operate on the principle of electromagnetic induction:
Transmit coils inside one side panel emit a low-frequency electromagnetic field across the archway.
Receive coils in the opposite panel monitor the stability of this field.
When an individual walks through carrying metal, eddy currents are induced in the metallic object, creating a secondary magnetic field that disrupts the baseline signal.
The detector's micro controller analyses this disruption against preset sensitivity thresholds and triggers audio beeps and visual LED zone indicators if a match is detected.
3. What is the difference between single-zone and multi-zone DFMDs?
The core distinction lies in detection granularity and screening speed:
Single Zone Detectors: Monitor the entire passage as a single detection field. If metal is present, the machine alarms, but security guards must conduct a complete body pat down with a handheld metal detector (HHMD) to find the object.
Multi-Zone Detectors (e.g., 6, 12, 18, 24, 33, or 48 zones): Segment the archway horizontally and vertically. Integrated LED lights on the frame immediately highlight the exact height and side (left, right, ankle, torso, pocket) where the metal is located, cutting secondary search time by more than 50%.
4. What types of metals can a DFMD detect?
Modern DFMD units detect both:
Ferrous metals: Iron, steel, and magnetic alloys (often found in weapons, tools, and construction components).
Non ferrous metals: Aluminium, copper, brass, zinc, silver, and gold. Advanced models feature adjustable discrimination settings to ignore harmless personal items like coins, keys, or belt buckles while maintaining full sensitivity for potential threats.
5. Are Door Frame Metal Detectors safe for pregnant women, pacemakers, and electronics?
Yes. Commercial DFMD systems use extremely low-frequency electromagnetic fields (VLF) that comply with international safety regulations (including CE, NILECJ, and OSHA standards):
Pacemakers & Defibrillators: The emitted field strength is well below levels that could disrupt active medical implants.
Pregnancy: There is zero ionizing radiation (unlike medical X ray machines), making it safe for pregnant individuals and children.
Electronics & Storage Media: Smartphones, laptops, magnetic swipe cards, flash drives, and camera memory cards can pass through without risk of data loss or hardware damage.
6. Can Door Frame Metal Detectors be used outdoors in rainy or dusty conditions?
Standard DFMDs are designed for indoor use. However, specialized weatherproof / outdoor DFMDs with an IP65 or IP67 rating are available for outdoor deployments, temporary gate entrances, sports stadiums, and construction sites. These outdoor units feature sealed control units, waterproof side panels, rubberized footings, and moisture-resistant circuitry.
7. How are DFMD false alarms prevented?
False alarms are minimized through systematic setup and calibration:
Sensitivity Adjustment: Calibrating overall and zone-wise sensitivity levels based on the specific threat profile of the facility.
Interference Filtering: Keeping the detector at a safe distance from heavy power cables, transformers, elevators, moving metal doors, or large HVAC units.
Uniform Spacing: Maintaining a minimum spacing of 0.5 to 1.0 meter between adjacent DFMD arches to avoid cross talk, or configuring them to distinct operating frequencies.
8. What is the average transit capacity / throughput of a DFMD?
A standard walk-through metal detector can process between 40 to 60 people per minute under smooth operating conditions. Actual flow rate depends on the screening policy, passenger compliance (e.g., placing bags on conveyor X-ray tables prior to entering), and whether multi-zone lights are used to speed up clear-outs.
9. What additional features are available in modern DFMD systems?
Current generation DFMDs often come equipped with:
Built in Transit & Alarm Counters: Dual-directional infrared sensors track total visitor volume and alarm counts.
Thermal Screening & Temperature Sensors: Integrated infrared sensors or thermal cameras for fever screening at entry.
Access Control Integration: Direct connectivity with turnstiles, flap barriers, or boom barriers to automatically lock access upon alarm.
Battery Backup: Integrated UPS or battery modules providing 4 to 8 hours of uninterrupted operation during power failures.
Remote Networking: TCP/IP and software interfaces for central control-room monitoring and real-time security logging.
10. How often should a DFMD be calibrated and serviced?
Daily Operational Check: Security staff should run a standard operational test piece (OTP) through the frame before each operational shift to verify alarm triggers.
Routine Calibration & Servicing: Professional calibration, hardware checks, and sensitivity alignment should be performed every 3 to 6 months under an Annual Maintenance Contract (AMC) to ensure consistent compliance and sensor accuracy.
