How radar fall detection works

Radar, without a recording.

A signal leaves the sensor. A reflection comes back. Changes in those reflections help Guardian sense movement in a room, without cameras, microphones or anything to wear.

To a reason to check in.

Sensing, supported processing, connection and a human response each have a different job. Explore what happens at each step.

Follow the signal

Start with the room.

Guardian observes changes in reflected radar energy. Its position and the room around it affect what it can observe.

Follow the placement guidance for the exact supplied model.

Movement becomes context.

Supported device and service processing turn observations into configured events or movement information. An activity pattern still needs the person’s own context.

Available information depends on the supplied model and service.

Bring nominated people in.

The connection, account and notification settings help supported information reach the receiving phone. Test those parts together during setup.

A notification is not a guarantee of delivery or a response.

People complete the connection.

A nominated person checks the situation and follows the agreed response plan. Decide who is available, who is the backup and what to do during an interruption.

of the system.

Good setup starts with the real space. Confirm suitability before choosing a sensor, then check the complete room-to-phone path.

Placement
Use the model’s installation guidance for position, orientation and the area you want to support.
Layout
Consider furniture, obstructions and changes to how the room is used. A room sensor does not travel with a person.
Power and network
Plan battery charging and a suitable WiFi or cellular connection. Agree what to do during an interruption.

Movement information.
Personal space.

Guardian does not capture video or conversations. Activity information still deserves care: agree participation, access and who needs to be involved.

Documentation status

Exact technical values and performance require current documentation for the supplied model and intended setup. Ask for the evidence behind the claims that matter to your decision.

Find the model-specific details

A few things worth knowing.

Does Guardian create an image of the room?

No. Guardian uses radar sensing and does not create a video feed or record conversations.

Does a radar observation explain why someone moved differently?

No. A movement observation needs the person’s routine, environment and appropriate care or clinical context. It does not identify the cause of a change or provide a diagnosis.

Where are the exact frequency, range and performance values?

Ask Aware for the current model-specific technical documentation and the evidence that supports its intended operating conditions. The diagrams on this page explain the process, not measured performance.

Does the person need to press a button for fall detection?

Guardian is room-based and senses configured fall events without a wearable or a button press. Placement and setup affect operation; events can be missed.

What happens if the connection is interrupted?

Notifications depend on the configured connection and service. Agree an alternative way to check in during an interruption, and follow the supplied guidance for charging and restoring the connection.

No sensing system detects every event. Placement, charging, connectivity and configuration affect operation. Guardian and Aware do not replace emergency services, clinical advice or in-person checks. Agree who responds and test the setup.
