Cannon County staff outline metal-detector options and praise SROs as part of school safety discussion
Summary
District staff reviewed a range of security equipment options — from handheld wands to advanced "Evolve" lanes — and said the district has focused on training, threat assessment and SRO deployment; full walk-through lanes would be costly and require operational planning.
District staff reviewed school safety options at the meeting, describing a spectrum of equipment and the operational work required to support it. A district staff member explained there are handheld wands that cost about $200 each, basic walkthrough metal detectors commonly priced around $4,500, and higher-end systems promoted around the country with prices cited by staff at roughly $120,000 per lane.
The staff member said those higher-end systems come with additional annual costs and require planning for staffing and infrastructure. "You start looking at the infrastructure there to, you know, how you're gonna manage it, the people to manage those things," the staff member said, adding that those systems can be portable and used for events such as games.
Staff emphasized that metal detectors are only one component of a broader safety program. The district described existing prevention and mitigation activities including coordinated school health, tabletop exercises, threat assessment training and regular safety drills; staff credited state guidance and a safety-focused program (described in meeting remarks as a "safety grant" used for purchases) for progress on mitigation measures.
School-based resource officers (SROs) also received positive mention. A staff speaker said this is the first full year with an SRO in every school and that SROs "have a lot of experience" and "jumped right in," helping principals and staff implement safety work.
Why it matters: While some districts have purchased high-end screening lanes, staff told the board that cost and ongoing operational requirements make such purchases a major decision. Metro Nashville was cited as budgeting about $1,100,000 a year for such machines over a four-year period as an example of scale; staff recommended considering security measures as part of a broader safety strategy rather than relying on a single piece of equipment.
No formal decisions or purchases were approved at the meeting. Staff asked board members to consider the tradeoffs of equipment cost, staffing needs and school climate when reviewing future safety proposals.
