technologies, they have limited applications and place security personnel in close proximity to potential danger. Additionally, performing a thorough inspection of the vehicle’s undercarriage using handheld mirrors is both time-consuming and labor-intensive, taking up to several minutes per vehicle. More importantly, most mirrors provide a limited view of the undercarriage, failing to show screeners key areas toward the middle of the vehicle.
