Presence and fall detection

Some rooms are too private for a camera.

Your product has to know when a room is occupied, or someone has fallen, without a camera. We do it with depth sensing and AI posture tracking, and help you build it in.

How it works

From a depth sensor to a fall alert

Someone sitting still barely changes the depth, and a fall can look like lying down on purpose. AI person detection and posture tracking tell them apart.

Our posture tracking on a ceiling sensor's 8 × 8 depth map as someone sits, then lies on the floor; the camera is only for comparison

  1. Room

    The room you want watched, from the ceiling.

  2. Depth sensor

    A multizone time-of-flight sensor on the ceiling.

  3. Person detection

    Tells a person from chairs and objects in each depth map.

  4. Posture tracking

    Follows sitting, standing and lying, and spots a fall.

  5. Nurse call

    Alerts a carer when someone is lying on the floor.

Where presence and fall detection sits: between your depth sensor and your nurse call.

What it handles

Spots falls, not bedtime

We tune it to your rooms, then check each reading and alert against what really happened in the recording.

What it catches

Sitting still
Someone seated and not moving.
Forward and backward
Falls in either direction.
Sliding down
Slow slides to the floor.
Two people
Two people in the room at once.

Sitting down
Sitting down quickly on a chair or toilet.
Carers
Carers and visitors in the room.
