Two Technologies, Two Threat Models
The weapons detection market has split into two distinct technology categories that share a name but solve different problems. Understanding the distinction prevents poor procurement decisions.
Camera-Based Visual AI Detection
Platforms like IntelliSee, ZeroEyes, and Omnilert identify drawn or brandished firearms through existing security cameras using deep-learning computer vision. The system monitors continuously across the entire camera network, detecting weapons the moment they become visible anywhere within the facility.
Walkthrough and Concealed Screening
Systems from Evolv, CEIA OPENGATE, Garrett, and Xtract One screen individuals at designated entry points using electromagnetic, magnetic moment, or metal detection technology. These systems identify weapons concealed under clothing, inside bags, or in containers as people pass through a physical chokepoint.
Head-to-Head: Where Each Technology Wins
| Dimension | Camera-Based AI | Walkthrough Screening |
|---|---|---|
| What it detects | Drawn, brandished, or visible firearms | Concealed weapons (guns, knives, metallic threats) |
| Coverage area | Entire facility, campus, parking lots, perimeter | Designated entry points only |
| Operational hours | 24/7/365 autonomous | Staffed hours at checkpoints |
| Infrastructure | Existing IP cameras + on-premises appliance | Dedicated screening hardware per entry |
| Staffing | Alert responders (existing security staff) | Operators at each screening lane |
| Visitor experience | Invisible — no interaction required | Active screening — walk through checkpoint |
| Deployment timeline | Hours to days | Days to weeks per entry point |
| Blind spots | Cannot detect concealed weapons | Cannot detect weapons past screening point |
When Visual AI Detection Is the Right Fit
Visual AI detection delivers the most value in environments where threat events can originate anywhere within a facility, not just at controlled entry points. Open campuses without perimeter fencing, facilities with multiple uncontrolled entry points, parking lots where weapons may be drawn before entering a building, and facilities that operate 24/7 without continuous security staffing.
The operational advantage is coverage. A 50-camera school deployment monitors every hallway, entrance, parking lot, athletic field, and common area simultaneously, without staffing any of those positions. The detection operates whether it is 2 PM during class or 2 AM during a break-in.
Beyond Weapons: 11+ Detection Types From One Platform
Some camera-based AI platforms detect threats beyond firearms. IntelliSee monitors for falls, slip hazards, unauthorized access, loitering, crowd formation, vehicle intrusions, smoke and fire, cell phones, perimeter breaches, and rooftop intrusions in addition to weapons. One platform, one appliance, one integration addresses the full risk matrix rather than deploying separate systems for each threat category.
When Physical Screening Is the Right Fit
Physical screening systems deliver the most value at high-volume, controlled entry points where concealed weapons represent the primary threat and throughput is a critical constraint. Stadiums, arenas, concert venues, courthouses, government buildings, and event spaces where attendees pass through a defined entrance.
The tradeoff is coverage scope and operational cost. Each entry point requires dedicated hardware and trained operators. Coverage ends at the screening boundary. If someone bypasses the checkpoint, or if a weapon is drawn inside the facility after clearing screening, the walkthrough system provides no additional protection.
The Layered Approach: When You Need Both
For many organizations, the most effective security architecture combines both technologies. Walkthrough screening catches concealed weapons at entry points. Camera-based AI monitors the entire facility for weapons that bypass screening or appear in zones without checkpoints.
K-12 School
Walkthrough screening at the main entrance for morning arrival. Camera-based AI detection across all cameras for continuous monitoring of hallways, perimeter, parking lots, athletic fields, and after-hours security.
Hospital
Walkthrough screening at the emergency department entrance. Camera-based AI detection across campus for behavioral health units, parking structures, lobbies, and corridors.
Stadium
Walkthrough screening at all public entry gates. Camera-based AI detection across parking lots, perimeter areas, concourse cameras, and VIP entrance zones.
Corporate Campus
No walkthrough screening (visitor experience priority). Camera-based AI across lobby cameras, parking structures, building perimeters, and common areas for continuous facility-wide monitoring.
Cost Comparison Framework
Camera-based AI detection typically involves a software subscription priced per camera or per appliance, one or more GPU processing appliances, and integration setup with existing notification and VMS systems. There is no incremental hardware cost per entry point and no dedicated screening staff requirement.
Walkthrough screening typically involves per-unit hardware cost at each entry point, software subscription for management and analytics, trained operator staffing at each screening lane during operational hours, and ongoing maintenance.
For a facility with 40 cameras and 3 entry points, the camera-based approach covers the entire 40-camera field with a single appliance and subscription. The walkthrough approach covers 3 doorways with 3 hardware units and staffing. The coverage surface area per dollar is dramatically different.
Questions to Ask Before You Buy
What is your primary threat? If the concern is concealed weapons entering through a controlled access point, walkthrough screening addresses that directly. If the concern is weapons being drawn anywhere on the property, camera-based AI addresses that directly.
How many entry points do you need to secure? Walkthrough screening cost scales linearly with entry points. Camera-based AI cost scales with camera count, not access points.
Do you have existing IP cameras? If yes, camera-based AI leverages that investment immediately. If your camera infrastructure is analog or minimal, the infrastructure investment changes the calculation.
What is your staffing reality? Walkthrough screening requires trained operators during all screening hours. Camera-based AI operates autonomously with alerts routed to existing security personnel.
Do you need 24/7 coverage? Camera-based AI monitors continuously with no incremental staffing cost. Walkthrough screening operates only during staffed hours.
