Ambient, predictive health monitoring

Vital signs, continuously. Nothing worn. No camera.

One sensor on the wall measures heart rate, respiration and movement through the air and through bedding, day and night. It gives care teams a trend they can act on days before a person deteriorates.

The problem we solve

Most of the day, nobody is watching.

Vital signs are usually taken by hand a few times a day. Between those checks a person can drift a long way from their own normal, and the first sign is often an ambulance.

Wearables only work when they are charged and worn. Cameras are not permitted in most of the places where watching matters most. Our sensor asks nothing of the person being monitored.

What care teams get

A trend, not a snapshot.

Each person is measured against their own baseline, so a change is meaningful even when every reading still sits inside the normal range.

1

Earlier warning

Continuous resting heart rate and respiration surface a sustained shift from a person's own baseline, typically days before an acute event.

2

Attention where it counts

Instead of watching everyone equally, staff see the small number of people whose overnight trend has moved, and can follow their own clinical protocol.

3

A record between visits

Nights, weekends and the hours between rounds are documented rather than assumed, which supports both clinical decisions and reporting.

Technology

Impulse radar, not millimetre wave.

The sensor emits an extremely low-power radio pulse and reads the micro-movement of the chest wall as a person breathes and as the heart beats. It works through blankets and clothing and does not depend on the person's posture.

  • Nothing to wear or charge

    Mounted on the wall or ceiling. No contact with the person, no compliance required, nothing for them to remove or break.

  • No camera, no audio

    Radar captures movement, not images. It can be used in bedrooms, bathrooms, seclusion rooms and cells where cameras cannot.

  • Processing on the device

    Vital signs are computed on the sensor itself, which keeps data volumes small and supports on-premises and in-country deployments.

Where it works

One platform, several settings.

The same sensor and the same analysis serve very different buildings. Choose the one closest to your organisation.

Evidence and regulatory

Cleared, certified and independently checked.

We would rather show the paperwork than make a claim. Full documentation is available to organisations evaluating us.

FDA 510(k)K202464, cleared April 2021 for heart rate and respiration in adults, including nursing homes and home healthcare
ISO 13485Quality system certified and audited annually under the Medical Device Single Audit Program
75.6%Of hospital transfers preceded by an alert across 201 admissions, certified by the Validation Institute in July 2024
Peer reviewedPublished work on early detection in skilled nursing, with further studies in progress

Cleared for prescription use in the United States, Canada, Australia, Singapore, Thailand and South Africa. Registration in other markets is in progress. The device measures heart rate, respiration, movement and presence; it is not an alarm system for acute life-threatening events and does not diagnose disease.

Deployment

Installed in minutes. Integrated on your terms.

A sensor goes up with two strips of tape and two cables. From there the data can stay entirely inside your environment or flow into the systems you already run.

  • Mount and power

    Wall or ceiling above the bed. No structural work and no wiring to the person.

  • Choose where data lives

    Our dashboard, your own systems through the API, or an on-premises deployment where data cannot leave the building.

  • Route alerts to your workflow

    Thresholds and escalation follow your protocol, not ours.

Partners

Distributors, resellers and monitoring providers.

We sell through partners in most markets. If you serve care organisations and want a contactless monitoring line, we should talk.

Distribution

Territory agreements for partners who can carry stock, install and support customers in their market.

Monitoring providers

For organisations running remote monitoring programmes who need a device that works without patient compliance.

Technology integration

API access for platforms that want continuous vital signs inside their own product.
