Core technology

Proactive incident detection for seniors and high-risk workers

A millimetre-wave radar keeps quiet watch over the room, tells ordinary sitting and lying from a sudden fall, and raises the alarm the moment something goes wrong.

Wireless sensing

Millimetre-wave radar covers bathrooms, bedrooms and other high-risk areas without complex cabling. Being camera-free, it monitors continuously while preserving privacy, and requires no wearable device.

Fall posture recognition

The system continuously analyses vertical displacement and posture changes, distinguishing normal sitting or lying down from a genuine fall, and flags prolonged motionlessness while keeping false alarms low.
