A camera in a parent's bedroom is a hard "no" for a lot of families — and understandably so. So how does a system detect a fall in a room where there isn't one?
The answer is radar.
What radar fall detection actually is
A radar sensor sends out a low-power radio signal and reads how it reflects back. From that reflection, it can tell whether a person is present, how they're moving, and whether someone has suddenly dropped to the floor — all without ever forming an image. There's no lens, no footage, and nothing that looks like a picture at any point in the process.
It works in complete darkness, through light fabric like a blanket or curtain, which is part of why it fits a bedroom at night.
What it can tell you
In BioAlign Care At Home, the radar sensors placed in the bedroom and bathroom:
- Detect a fall and alert the family
- Monitor overnight wellness — breathing, heart rate, and restlessness through the night
- Flag if someone is out of bed longer than expected
Where a camera is still part of the system — and why
To be clear about how BioAlign Care At Home actually works: the tablet in the living area does use a camera, because that's what makes walking and balance tracking possible — you can't measure how someone walks without something that can see them walk. Fall detection and movement tracking run on the tablet itself, and camera video is never uploaded or recorded by us.
The point isn't "no cameras anywhere." It's the right sensor for the right room — a camera where your parent spends their day, and radar, with no camera at all, in the rooms where privacy matters most.
Why this combination matters
The bedroom and bathroom are exactly the rooms where a camera isn't an option for most families, and exactly the rooms where falls are hardest to catch any other way. Radar fills that gap without asking anyone to give up their privacy to get it.
