WiFi Fall Detection · No Camera · No Wearable
Sensafe makes a WiFi-based fall detector for the home. Two small sensors read how WiFi signals move through a room, and catch a fall within three seconds — day or night, without a camera or anything to wear. It sends alerts over the WiFi you already have, no new router or subscription needed.
Why WiFi sensing
Most fall detection asks someone to wear a pendant they'll forget, or puts a camera somewhere private. Sensafe reads the WiFi signal itself — the same WiFi signals already filling the room — so it never sees an image and never needs to be worn.
Sensafe never captures an image. It reads how motion bends the WiFi signal between two sensors — the room stays private, always.
There's no pendant, wristband, or app to remember. The sensors mount once and run continuously in the background.
WiFi signals don't need light. Detection works the same at noon, at 3am, or through a closed door.
WiFi travels on a lower frequency than the radar used in most fall detectors, so it passes through walls, doors, and shower curtains more easily. Placement is more forgiving.
Sensafe connects to your home's existing WiFi network to send alerts. No new router, hub, or subscription to set up.
How it works
One sensor sends WiFi packets, the other listens. How those packets change tells us what's happening in the room.
01 / Sense
A sender unit sends out WiFi packets. A receiver unit across the room picks up every one.
02 / Read
A packet looks slightly different depending on what's moving between the two sensors. Stillness looks one way; a person moving, or falling, looks another.
03 / Decide
Every three seconds, a compact machine learning model checks that pattern and decides: was that a fall, or not.
04 / Alert
If the vote crosses the threshold, the sensor briefly connects to your home's existing WiFi and sends an alert — then returns to listening. No new network required.
Illustration — Sensafe can be installed in other rooms too.
Under the hood
No footage leaves the room, and no cloud service has to be reachable for detection to work — only for the alert.
