How a door frame metal detector works
A door frame metal detector (DFMD), also called a walk-through metal detector, has transmitter and receiver coils hidden inside its two side panels. The transmitter creates a pulsed magnetic field across the doorway. When a person carrying metal walks through, the metal disturbs the field, the receiver picks up the change and the control unit compares it with the sensitivity programme that has been set. If the signal is above the threshold, the unit gives an audio alarm and lights up the zone where the metal was found. Small personal items such as a few coins or keys can be ignored by setting the programme correctly, while larger metal objects still raise an alarm.
A DFMD screens people only. Bags and parcels go through an X-ray baggage scanner (see the X-ray baggage scanner price list), and a guard uses a handheld metal detector to clear each alarm. Most security check points in Delhi NCR use all three together.
Single zone vs 6, 18 and 33 zone detectors
| Single zone | Only tells the guard that metal is present somewhere on the person, so every alarm needs a full handheld search. Suited only to very light use. |
|---|---|
| 6 zone | Shows roughly where the metal is from head to foot. A practical choice for offices, schools, clinics, banks and receptions with moderate footfall. |
| 18 zone | Finer height zones, often with left, centre and right indication. Common at malls, hotels, hospitals and corporate towers where guards need to clear alarms quickly in peak hours. |
| 33 zone | The most precise location display. Used at high-security sites such as courts, government buildings, stadiums and large events. |
More zones help the guard find the object faster; they do not by themselves make the detector “stronger”. Choose the zone count from your peak footfall and how strictly you have to screen. Our multi zone DFMD guide explains this choice in more detail.
DFMD vs handheld detector vs X-ray scanner
| Door frame metal detector | Screens every person quickly without contact. Fixed at one entry point. Tells you that metal is present and roughly where. |
|---|---|
| Handheld metal detector | Low cost and portable. Used by a guard for a close check after a DFMD alarm, or alone at small sites and events with few visitors. |
| X-ray baggage scanner | Shows what is inside bags and parcels on a screen. Needed where bags must be checked, such as malls, hotels, courts and offices with strict entry rules. |
What changes the price of a door frame metal detector
We do not publish a fixed price list, because two detectors that look alike can be quite different inside. These are the points that change a quotation:
- Number of zones and the type of zone display (LED bar on the panels, control unit display or both).
- Detection electronics: number of sensitivity levels, preset programmes and how well the unit ignores small items without missing larger ones.
- Indoor or outdoor model: an IP65 outdoor unit costs more than an indoor one, but it is the right choice for an open gate.
- Extras: people and alarm counters, battery backup, networking for remote monitoring, a camera or a temperature check.
- Quantity and site work: number of lanes, floor fixing, power points and whether a handheld detector or X-ray scanner is part of the same order.
- Warranty and AMC: length of warranty and how quickly a local engineer can visit.
When you compare two quotations, check that both list the same zone count, outdoor rating, extras and service terms. A lower price with no local service often costs more over the life of the detector.
How to choose and place a DFMD
- Count your busiest hour. One detector lane with one or two guards can handle a steady line; morning peaks at offices, colleges or malls may need two lanes.
- Keep it away from interference. Lifts, escalators, sliding steel gates, heavy power cables, motors and generators near the frame cause false alarms. We check the spot before fixing the unit.
- Fix it firmly. A detector that rocks when people walk through can false-alarm. Permanent units are anchored to the floor; event units stand on a stable base.
- Plan the flow. Leave space for a guard with a handheld detector after the frame, a tray table for phones and keys, and a separate path for wheelchairs and staff with medical devices.
- Set it on site. Sensitivity is tuned at the actual entrance with test objects, then guards are trained on what each alarm means.
- Open gate? Choose an outdoor model or put the unit under a canopy, and keep the control unit out of direct rain.
