How Next-Gen Walk-Through Gates Reduce False Alarms

You know the scene: A crowded entrance. The beep-beep-BEEP of your metal detector. Four people backtracking, emptying pockets of keys and phones. The line grinds to a halt.

Yes. Walk-through metal detectors have become a critical part of modern security systems in airports, schools, stadiums, and government buildings. However, false alarms have long been a major challenge—slowing down operations, frustrating security staff, and reducing efficiency.

Here’s the uncomfortable truth:
Traditional security gates often mistake everyday items for threats.
That “high sensitivity” setting? Yes, It’s making you safer but also slower.

Why False Alarms Are Your Hidden Enemy

  • Lost productivity: 30+ seconds per false alarm × 500 visitors/day = 4+ hours of wasted time

  • Staff fatigue: Operators become desensitized to alerts (“cry wolf effect”)

  • Security gaps: Real threats slip through during chaos

Yeap! Such a long line. 😀

How Our Gates Silence the Noise

1. Accurate Detection

Unlike single-zone detectors, our Walk-Through Metal Detector (e.g. SE3310) features 33 horizontal zones with granular 1000 grades adjustable sensitivity.
. This precision engineering enables reliable detection of threat items ranging from concealed blades to small coins.

When a subject passes through:

  1. Pinpoint threat location: LEDs on both panels illuminate at the exact height of detected metal objects

  2. Multi-target discrimination: Simultaneously identifies metals in 3+ body areas (e.g., waist, ankle, pocket)

  3. Adaptive profiling:

    • Boosted sensitivity at lower zones (optimized for footwear weapons)

    • Reduced sensitivity at head level (prevents false alarms from dental work)

2. 60 Built-in Security Detection Programs

It is not easier to set the accurate security levels, users can choose directly from the known 60 It is not easier to set the accurate security levels, users can choose directly from the known 60 embedded security standards by the use of a range of possible sensitivity settings.

 

3. Audible and Visual Alarms & Acoustic Alarm Signaling System

  •  Audible alarm and visual LED lights signal when a target has been detected.

  • Provide ability to randomly alarm on a selected range of 16 tones intensity levels.The wide 10 volume control dynamic allows operation even in very noisy environment .(also support silent mode)

Why This Isn’t Just “Another Metal Detector”

  • Rain or shine: Operates at -10°C to 45°C 

  • Superior Design & Construction: Completely Modular for quick installation. Overhead control unit with 7-inch LCD capacitive touch screen. The overall system is characterized by sturdy, reliable electronic and mechanical construction

  • Compliance: Comply with CE, RoHS, FCC certificate, strictly follow the standard of EN60950, EN50081-1, GB15210-2003, ISO9001 Quality Management System

Better User Experience, Less Interruption

Reducing false alarms doesn’t just improve security—it also improves the flow of people through checkpoints. Fewer stops mean shorter lines, less frustration, and smoother operations overall.

For high-traffic areas like airports, train stations, and stadiums, this translates into better customer satisfaction and increased efficiency.
