Technical Review and Optimization of Walk-Through Metal Detector Processes

The growing concern of terrorist violence in western countries has placed an emphasis on the critical nature of effective security practices. It is imperative to identify vulnerabilities, and close security gaps before they can be exploited by extremists. As such we desired to develop a technical testing process to validate the effectiveness of security practices and policies for large sports venues. This study of methodology, technical performance, and implementation of walk-through metal detectors screening processes sought to pinpoint weaknesses in existing measures. Though a series of laboratory testing, field testing, and site observations - performance degradation and detection failure was determined to be induced by one of three aspects; Setup - interference and synchronization between units, Settings - incorrect or inappropriate for conditions, and Operators - ineffective training and procedures. By identifying these anomalies and discrepancies security personnel are able to eliminate or reduce vulnerabilities and calculate a more accurate risk assessments for assets, personnel, and patrons.
