School Shooting Prevention: Why Early Detection Matters

When people talk about preventing school shootings, the conversation often jumps straight to the day of an attack. But the best chance to prevent violence usually comes much earlier, in the ordinary weeks of a school year, when a student is struggling and someone notices. A useful way to think about prevention is as three levels, each building on the one before it.
Level 1: A community that reports concerns
The foundation is a school culture where students, families and staff feel comfortable saying something. Anonymous tip lines, clear reporting paths and adults students trust all matter here. The U.S. Secret Service National Threat Assessment Center has found that in many school attacks, other people had concerns about the attacker beforehand.
What schools can do
- Make reporting easy and anonymous, and tell students what happens after they report.
- Teach staff the warning signs of a student in crisis, not only the signs of a threat.
- Follow up on every report, even the ones that turn out to be nothing.
Level 2: Behavioral threat assessment
Reports only help if someone acts on them. A multidisciplinary threat assessment team, typically an administrator, a counselor or psychologist and the school resource officer, reviews concerns, talks with the student and family, and builds a support plan. The goal is to help the student, not just to discipline them.
Signs that a concern is escalating
- A change in behavior that friends or teachers notice and mention.
- Talk about harming others, or interest in past attacks.
- Trouble at home, isolation or a recent loss.
Level 3: The day itself
If the first two levels miss something, the school day itself is the last chance to notice and respond. This is where physical security, staff on the ground and technology come together. Cameras already cover entrances, hallways and parking lots at most schools, but nobody can watch every feed at once.
This is also where everyday safety and serious incidents overlap. The same awareness that helps staff find a student who has fainted in a stairwell or a fight starting behind the gym also helps them understand an emergency and where it is unfolding.
Why the levels work together
Each level catches what the one before it misses. Schools that invest only in the final level are betting everything on the shortest window. Schools that build reporting and threat assessment first give themselves far more chances to help a student before anything happens.
Putting it into practice
- Start with reporting and a working threat assessment team.
- Practice your emergency plan with staff, including who calls whom.
- Review where your cameras are and which areas nobody watches.
- Choose technology that supports your people rather than replacing them.
Where VOLT fits
VOLT is built to notice moments: a fall, a fight, someone where they shouldn't be.
VOLT tracks a person by visual appearance across the camera footprint and shows that track on a 3D floor plan, so first responders reach where the situation is unfolding now, not where it started.
VOLT detects handguns, long guns, and knives that are visible to the camera. It doesn't see through clothing or into bags.
VOLT is built to run on the cameras you already have. Some older analog cameras may need an upgrade.
VOLT is built to run on the cameras you already have.
By default, a VOLT reviewer checks it before your team is notified.
VOLT notices moments as they happen, and by default a VOLT reviewer checks each one before your team is notified.
VOLT helps your team get location details to 911.
