Walkthrough & Handheld Metal Detectors in Security Screening

In today’s high security environment as data center, metal detectors are essential tools for keeping unauthorized items out.

Here’s a quick breakdown of how security teams use them effectively:

✅ Walkthrough Metal Detector (WTMD):
• Positioned at entry points (especially at Data Centre buildings) to screen individuals one at a time.
• Calibrate sensitivity settings according to the threat level and policy.
• Requires removal of metal items like keys, phones, coins or belts and place into a tray for separate screening.
• If an alarm is triggered, the person is directed to secondary screening.

✅ Handheld Metal Detector (HHMD):
Purpose : To perform a focused search on areas that triggered WTMD alarm or targeted screening.
• Scan from head to toe, keeping a respectful distance (1–2 inches).
• Any alert requires item verification, ask the individual to show/remove item.

Best Practices:
• Always maintain a professional, respectful approach.
• Ensure same-gender personnel for handheld scans when possible.
• Document and report any security breach immediately.

Security is not just about equipment it’s about people, processes and principles. Make sure the security personals is trained, alert and compliant.
