The room nobody can look into, measured for stillness.

A bathroom with the SUHO sensor on the wall

In a washroom nobody is looking, and a person who has stopped moving cannot press a button or call out. SUHO reads occupancy and movement with radar. When someone is present, breathing, and has not moved for longer than the time you set, it notifies the staff you name.

  • No camera, no microphone, no image, no audio.
  • Threshold set per washroom: 2 minutes 30 seconds by default.
  • Long-stay notification when a room stays occupied too long.
  • The same radar platform as the XK300, on the wall or ceiling.
How SUHO decides

Moving is normal. Still, with only breathing left, for too long, is not.

Occupied, movingStill, breathing only Normal use of the room · no timerThe stillness timer runs Threshold: 2 minutes 30 seconds by default, set per washroom Notify staff Illustration. Movement and breathing are read by radar; nothing is recorded as image or sound.
01

Occupied: a person is in the room

02

Moving: normal use, no timer

03

Still, with breathing only: the timer starts

04

Past the threshold: staff are notified

Two notifications, and the room’s numbers

Motionless occupant

Someone present and breathing, without movement, beyond the threshold for that room.

Long stay

A room occupied beyond a set duration, 8 minutes by default, for a check-in knock.

Where notifications go

Sound and a visual on the dashboard, SMS and email to the staff you name, and webhooks into your systems.

Room use

Entries, total time in use, and occupied or vacant right now, for cleaning rotas and reporting.

Staff washrooms and locker rooms, where people are alone.

The notification reaches staff. They knock, and go in.

Where it fits

Patient and shared bathrooms, shower rooms without a bathtub, staff washrooms and locker rooms, accessible toilets, and other rooms where a person awake keeps moving.

Where it does not

Bedrooms, rest areas and bathtubs, where lying still is normal. In bedrooms, the XK300 measures heart rate and breathing instead.

SUHO reports two things: whether a person is present in the detection area, and how long they have been without body movement. Both are named in the XK300’s FDA clearance, K202464, which covers presence or absence within seven metres and the length of continuous motion or absence of motion. SUHO shows no vital signs, makes no vital-sign claim and diagnoses nothing. What the threshold is, who is notified and what they do next are set by your own policy, not by the device.
