The "Dumb Sensor" Problem
Traditional motion sensors (PIR) are binary: something moved, or it didn't. They cannot distinguish between a cleaning robot, a stray dog, a curtain blowing in the wind or a corporate spy. This leads to "Alert Fatigue," where security teams ignore alarms because 99% of them are false positives.
In a high-security environment, "Motion Detected" is not actionable intelligence. You need to know what moved and who it is.
The Science of Digital DNA
TrustGate™ Network introduces the concept of Device-Free Identity. We don't just detect motion; we analyze the biometric signature of the movement itself.
Every human being interacts with Radio Frequency (RF) signals in a unique way. This interaction is determined by their physical biology and mechanics:
- Body Mass & Height: The physical volume of signal they displace creates a specific magnitude of disturbance.
- Gait Velocity: The speed and cadence of their walk is unique to them.
- Limb Swing: The unique Doppler shifts created by arm and leg movement create a "micro-Doppler" signature.
How "Gait Analysis" Works
When an authorized employee walks down a secure corridor, TrustGate™ analyzes their "Gait Signature" in real-time using advanced Machine Learning models trained on Channel State Information (CSI). The system compares this signature against a known database of authorized personnel.
- Match: The doors open automatically. No badge required. The building effectively "recognizes" them.
- Mismatch: The system flags an "Unknown Entity" and tracks them on a 3D floor plan, alerting security to a potential breach.
The Security Implication: Ending Tailgating
This prevents the most common physical breach: Tailgating (or Piggybacking). If an intruder follows an employee through a secure door, a camera sees two people. It might not know if the second person is authorized.
TrustGate™ sees "One Authorized Gait" and "One Unauthorized Gait" entering simultaneously. It instantly separates the signals and triggers a silent alarm. This is the difference between monitoring and intelligence.
