Metal Detectors for Schools

Metal Detectors for Schools — What You Need to Know

School safety is no longer optional. With weapon-related incidents on the rise across K-12 campuses and universities, more school districts and administrators are turning to walk-through metal detectors for schools as a frontline security measure. PTI has been supplying school metal detectors to educational institutions across the United States for over 30 years.

Why Schools Are Installing Metal Detectors

The data is clear: schools that implement walk-through metal detectors see a measurable deterrence effect. A metal detector for school entrances does not just detect threats — it signals to students, staff, and parents that safety is a priority. Common threats detected include knives, firearms, and other concealed metallic weapons. Modern school metal detectors are fast, accurate, and ADA compliant — capable of screening hundreds of students per hour without creating bottlenecks at building entrances.
