One camera. QR scan. A complete decision in milliseconds.

Metrici's QR Code Reader turns any IP camera into a smart verification point. No dedicated scanners. No new cabling. Just existing infrastructure, AI-powered. And when combined with LPR, Container Code Recognition or Thermal Analyzer, a single entry point becomes a multi-layer checkpoint.

How It Works

From Scan to Decision in Milliseconds

A camera reads the code. Metrici checks the database. The result fires instantly.

Step 01
📷

Camera Captures the Code

Any IP camera pointed at an entry point, conveyor belt or loading dock captures the QR code — even at distance, at an angle, or in motion.

Step 02
🧠

Metrici Decodes & Validates

The AI engine decodes the QR in real time and cross-checks against the Metrici database — access list, schedule, zone permissions, expiry and linked records.

Step 03

Instant Decision & Trigger

Access is granted or denied in milliseconds. A barrier opens, a relay fires, an alarm sounds — or another Metrici engine is triggered for multi-factor verification.

Step 04
💾

Event Logged with Photo

Every scan is saved with decoded value, timestamp, camera, zone and a timestamped photo. Full audit trail for compliance, billing and investigation.
