Weapons Detection Systems
Weapons Detection Systems
At Poplar Bluff Schools, student and staff safety is our highest priority. We are committed to providing a safe, welcoming, and focused environment where all students can learn and thrive.
As part of our ongoing efforts to enhance school security, we have implemented state-of-the-art OpenGate weapons detection systems at Poplar Bluff High School, Junior High, and Mark Twain Alternative School. These advanced systems add an extra layer of protection, giving peace of mind to families, staff, and students. By taking proactive steps now, we are demonstrating our strong commitment to preventing potential threats before they reach our school doors.

Given the increased awareness around school safety nationwide, our district is taking proactive measures to prevent potential threats from entering the educational environment. Weapons detectors serve as a preventive tool, providing an extra layer of security and peace of mind for families, staff, and students. Future expansion across the district is being considered following this pilot rollout.
After careful review, it was determined that OpenGate is the most effective system for our schools. These advanced detectors use modern sensors and imaging technology to accurately distinguish between weapons and harmless metal objects, significantly reducing false alarms and improving detection accuracy. Additionally, they are portable and can be used at multiple locations and events.
-
Poplar Bluff High School, Junior High, and Mark Twain Alternative School will have the weapons detection systems in place.
-
The system consists of two towers that students and visitors walk through upon entry. If the towers turn green, no threat has been detected, and the person passes through without stopping. If a potential threat is identified, the towers display a red light and sound an alert, and the individual will undergo a quick secondary screening
-
Trained staff will guide the individual through a secondary screening process, which may include checking backpacks or using a handheld metal detector.
-
Screenings will be conducted by Poplar Bluff R-I staff members who have been thoroughly trained on system operations and safety protocols.
-
All students and visitors will be screened before entering the building.
-
Yes. All students will be screened unless it is determined that a student poses no threat or cannot participate due to specific disabilities.
-
Entry time will vary by school. We encourage students to arrive on time. Other districts using similar systems have reported that entry times become quicker each day as students and staff become familiar with the process.
-
Yes. The system will be used at large events on school grounds, such as athletic games, concerts, and plays, as well as additional events off campus like graduation and prom.
-
Yes, knives are among the items the system is designed to detect.
-
Yes, it is also capable of detecting vapes and similar devices.
-
In line with FDA guidance, visitors and staff with implantable or wearable medical devices should consult their device manufacturer or physician regarding exposure.
-
Chromebooks, laptops, and large metal notebook spines may activate the system due to their shape and metal density. More detailed guidelines for these and other items will be provided to students and families prior to implementation.
-
Yes. The system uses extremely low-frequency radio waves (ELF), a non-ionizing technology compliant with the Institute of Electrical & Electronics Engineers (IEEE) 2019 safety guidance for general public exposure.
-
No. The technology does not use facial recognition. It evaluates objects passing through, not personal identity.
-
Yes. Board of Education policy was revised and adopted in December 2024. Policy JFG: Searches of Students now covers the use of Weapons/Metal Detectors in our schools.
