Introduction
Security screening is critical for facilities with high visitor traffic. A large public facility sought to enhance entry-point safety while maintaining smooth throughput. Previously, security relied on handheld metal detection wands, which were slow, inconsistent, and labour-intensive.
The facility implemented the Scanline Walk-Through Metal Detector to address these challenges.
- High daily foot traffic causing long queues at manual screening points before installing the Scanline Walk-Through Metal Detector
- Reliance on operator skill, leading to inconsistent detection without a Scanline Walk-Through Metal Detector system
- High manpower requirement to scan each visitor manually instead of using a Scanline Walk-Through Metal Detector
- Visitors experienced intrusive and slow entry before the Scanline Walk-Through Metal Detector was implemented
- Limited deterrence against carrying prohibited metal objects without a Scanline Walk-Through Metal Detector
Solution Implemented
The Scanline Walk-Through Metal Detector was installed at main entry points. Key features and setup included:
- Multi-zone detection in the Scanline Walk-Through Metal Detector to identify the location of metal objects
- Adjustable sensitivity in the Scanline Walk-Through Metal Detector for balancing detection accuracy and false alarms
- Visual and audible alarms on the Scanline Walk-Through Metal Detector for instant alerting
- Hands-free, contactless screening for all visitors using the Scanline Walk-Through Metal Detector
Handheld wands remained available for secondary inspections when an alarm from the Scanline Walk-Through Metal Detector was triggered.
Results and Benefits
1. Increased Throughput
- Continuous screening allowed visitors to walk through the Scanline Walk-Through Metal Detector naturally
- Reduced bottlenecks during peak periods after installing the Scanline Walk-Through Metal Detector
- Screening time per person reduced from several seconds per manual scan to nearly instantaneous detection with the Scanline Walk-Through Metal Detector
2. Consistent Detection
- Screening with the Scanline Walk-Through Metal Detector is operator-independent, providing standardised results for every individual
- Adjustable sensitivity in the Scanline Walk-Through Metal Detector reduces false positives while ensuring threats are detected
3. Reduced Staff Burden
- Fewer personnel are required at entry points due to the Scanline Walk-Through Metal Detector
- Staff could focus on monitoring alerts, secondary checks, and crowd control
4. Strong Deterrence
- Visible presence of the Scanline Walk-Through Metal Detector discourages attempts to carry prohibited items
- Improves the perception of safety among visitors
5. Improved Visitor Experience
- Contactless, non-intrusive screening with the Scanline Walk-Through Metal Detector
- Faster, smoother entry process without compromising security
Comparison: Walk-Through vs Handheld Wand
| Feature |
Walk-Through Metal Detector |
Handheld Metal Detection Wand |
| Throughput | Screens hundreds per hour | Manual scanning only |
| Screening | Hands-free | Requires close contact |
| Consistency | Operator-independent | Operator-dependent |
| Deterrence | Strong – visible archway | Moderate – wand is less intimidating |
| Staffing | Low requirement | High requirement |
| Best Use | High-traffic entrances | Secondary checks / small screening |
The Scanline Walk-Through Metal Detector enabled the facility to:
- Screen visitors faster and more reliably
- Reduce reliance on manual wand checks
- Enhance safety and security confidence
- Maintain efficient, non-intrusive entry for high traffic volumes
