mmWave radar senses breathing, heartbeat and presence through blankets, seats and clothing. That is why it is becoming a key sensor for in-cabin safety.
A driver can be alert one moment and unresponsive the next — from a cardiac event, a seizure or another sudden medical emergency.
Camera-based driver monitoring tracks the eyes and head, but a slumped driver can look much like a resting one. Adding 60GHz radar lets the system read breathing and heart rate, confirming whether the driver is still responsive.
Children left behind in parked cars face life-threatening heat within minutes — often because a sleeping child was simply forgotten.
A sleeping infant under a blanket or in a rear-facing seat is easy to miss. Radar senses the tiny chest movement of breathing, even through fabric. Euro NCAP now rewards systems that detect a child directly, rather than relying on door-opening reminders.
Seat belt reminders and airbag decisions depend on knowing who is in each seat. Get it wrong, and a warning is missed.
A weight sensor can't tell a small child from a heavy bag, and a camera can't see a passenger hidden behind a seat. Radar tells living occupants from objects by their breathing and movement, without capturing a single image.
A break-in takes seconds — and by the time an alarm sounds, the damage is often done.
A roof-mounted radar watches the cabin and the area around the car, warning when someone lingers and alarming when they reach inside. It records no video and draws little power — the next step after NUTEK's 45 years in vehicle security.
Illustrative scenario. Actual performance depends on sensor configuration, installation and system integration.
Cameras read faces, weight sensors read pressure. Radar reads the signs of life — even when the person is hidden from view.
