How raw sensor noise becomes a verified, actionable human alert

01 Raw Sensor Events
All acoustic, RF, thermal, seismic and optical triggers — including noise, wind, vehicles, birds
↓ AI filters by signature
02 Suspicion Events
Events that match a known threat signature on at least one sensor. False positives still present.
↓ Cross-sensor agreement required
03 Confirmed Detections
2+ sensors agree. Location fix computed via TDOA. Threat classified and tracked.
↓ Evidence packaged + operator notified
05 Human Alerts Sent
Actionable alert with GPS coords, sensor evidence, threat type and confidence score. Human decides.
