The Stillsense system, in detail.
What Stillsense senses, how it’s built, and the privacy that comes from creating no image at all — the technical detail, stated honestly.
Built to notice what matters, and nothing it shouldn’t.
| Capability | Status | What that means |
|---|---|---|
| Presence detection | Available | Knowing whether someone is in a room, reliably and in real time |
| Motion & activity | Available | Recognising movement and the rhythm of a normal day |
| Bed-exit & night activity | Available | Noticing when someone gets up, or has a restless night |
| Fall detection | Available, under independent validation | Detecting likely falls in real time; we’re completing a formal validation study before making any safety-grade guarantee |
| Whole-home coverage | Available, improving | Sensing across rooms from few devices; range depends on the home’s layout |
| Breathing-rate monitoring | On our roadmap, validation-gated | Contactless respiration trends during sleep — promising, but we won’t bring it to a care setting until it’s clinically validated |
| Heart rate & detailed posture | Research only — not offered | Interesting in the lab, not dependable enough for real homes. We won’t put it in front of a vulnerable person until that changes. |

We market only what’s in the “Available” rows. Fall detection ships with an independent validation study in progress before any safety-grade guarantee.

Values marked in development are confirmed before publication — we don’t state unverified figures.
- Sensing method
- Wi-Fi Channel State Information (CSI) — no camera, no microphone, no radar required
- Sensor unit
- Compact Wi-Fi sensor node, mains / USB powered · model & dimensions in development
- Processing
- On-device (edge) inference; no cloud dependency required · hardware platform in development
- Connectivity
- Standard Wi-Fi (2.4 / 5 GHz); works with existing access points · Wi-Fi 6/6E nodes optional
- Coverage
- Room-level per sensor; whole-home from a few; through-structure, layout-dependent · range figures in development
- Detection latency
- Real-time event detection · latency figures in development
- Data
- No image or audio created; events processed and stored on-device; encrypted in transit and at rest
- Power
- Mains / USB / PoE · typical draw in development
- Operating conditions
- Indoor · temperature & humidity range in development
- Integrations
- Response-centre platforms; journal/EPJ via VKP; Matter / Home Assistant (Home edition); API & SDK (Core)
