The Problem
School security today is fragmented by design. Most campuses operate separate systems for access control, visitor management, intercoms, and threat screening — each with its own interface, blind spots, and failure points. The result is not layered security, but layered complexity, with gaps wide enough for a threat to walk through.
The Solution
Certus is a unified two-layer security architecture developed by ZKTeco USA that combines the FMD Pro metal detectors with the Cielo365 cloud-based access control platform. It is the only solution on the market that screens for concealed threats before the door and verifies every individual at the door.
How It Works
Layer 1
Threat Screening at the Perimeter (FMD Pro)
Before any individual reaches the entry door, FMD Pro performs passive metal detection across three scan zones simultaneously. The system identifies firearms, ferrous metals, and contraband,
including smartphones, at a throughput of 35 people per minute. No radiation. No physical contact. No disruption to the flow of students and
staff. Detected threats trigger an immediate staff alert; cleared individuals proceed without delay.
Layer 2
Identity Verification at the Door (Cielo365 + Omni Reader)
Every person who reaches the entry door is verified by the Omni reader — supporting card, mobile credential, biometric, QR code, or PIN. Authorized individuals are granted access instantly. Visitors trigger an integrated video intercom workflow: the front office connects in real time, ID is captured, a badge is issued, and the visit is logged automatically. Every event — entry, visitor check-in, alarm, denial, is recorded and pushed to the Cielo365 cloud dashboard in real time, accessible from one administrative interface across all campuses, doors, and sites.
Why Certus Is Different
Most campus security upgrades add hardware. Certus adds architecture. The distinction matters: hardware additions create more systems to manage and more point of failure. Certus unifies access control, visitor management, video intercom, and real-time event logging under a single operational layer. Administrators gain district-wide visibility. Security staff gain instant alerts. Students and staff experience no friction. Visitors are managed, not waved through.
- Concealed dangerous objects detected before any individual reaches a secured entry point
- 35 persons per minute processed with zero radiation and zero contact screening
- All access events, visitor records, and security alerts centralized in real time
- One dashboard manages every campus in a district — all doors, all sites, all students
- Replaces 3–4 siloed systems with a single, fully integrated solution
