Perception for camera-denied environments
Camera-free RF human sensing — presence, activity, and breathing detected through commodity Wi-Fi, no cameras
"Project ICU"
YHDA builds camera-free RF sensing that detects people where cameras can't — in darkness, smoke, and visual clutter. Privacy-preserving perception for the real world.
Overview
RF Human Sensing
Detect human presence and movement through smoke, darkness, and visual clutter — using commodity WiFi signals. No cameras, no images, no privacy intrusion.
Through-obstacle
Privacy by design
Activity & Zone Detection
Know what’s happening, and where
Our pipeline classifies presence, standing, walking, sitting, and coarse location in real time — turning raw RF into actionable situational awareness.

From WiFi today to radar tomorrow
We prove the science on low-cost commodity hardware now, with a clear roadmap toward dedicated UWB and radar sensors for robust deployment in camera-denied environments.

Privacy by Design
Sensing without surveillance
No cameras, no images, no recordings. YHDA detects people from radio signals alone — delivering situational awareness in places where cameras are intrusive, blocked, or simply can’t see.

HOW IT WORKS
From radio waves to real-time perception
A four-stage pipeline that turns ordinary WiFi signals into live human-sensing — running end to end on low-cost hardware.
01
Capture
A commodity WiFi link continuously measures Channel State Information (CSI) as people move through the space.
02
Process
Raw RF signals are cleaned, filtered, and transformed into structured features ready for analysis.
03
Classify
On-device machine learning identifies human presence, activity, and coarse location in real time.
04
Visualise
A live radar-style dashboard displays detections, activity, and zones with sub-second latency.
WHY RF SENSING
Sensing where cameras fail
YHDA detects people through smoke, darkness, and walls — using radio signals alone, with no images and no privacy intrusion.
Privacy by Design
No cameras, no images, no recordings. Situational awareness without surveillance, suitable for homes, care settings, and sensitive sites.
Works Where Cameras Can’t
Penetrates smoke, darkness, dust, and visual clutter — operating in the zero-visibility conditions where optical sensors fail.
Commodity Hardware
Built on low-cost, off-the-shelf WiFi hardware — no specialist sensors required to detect human presence and movement.
Real-Time Awareness
Classifies presence, activity, and coarse location live, turning raw radio signals into actionable situational awareness.
Built for Search & Rescue
Designed for camera-denied emergencies: locating people in smoke-filled buildings, collapsed structures, and low-visibility environments.
A Clear Roadmap
Proven today on WiFi, advancing toward dedicated UWB and radar hardware for robust field deployment.
