Release note: Tellu Camera Application - June 17th, 2026

Tellu Camera App (shortened to TCAP) is the software application that runs on compatible AXIS cameras to enable event-based supervision. It continuously monitors a residents state and detects their transitions in a room, such as in and out of a bed, in and out of room, or fall.

Adjustments in Exclusion Zone for Fall Detection

Over the past months, we have received valuable and sometimes contradictory feedback regarding fall detection, which has highlighted the trade-off between false and missing alarms. To support effective and safe use of fall detection as a part of a broader set of procedures and alarm types, the following section aims to clarify how technologies such as ours (camera and radar for instance) detect falls.

The algorithms in the camera monitors the position and posture of the resident to detect its state and identify situations with high risk, which could be the result of a fall. A fall is triggered if the patient is detected in a fallen state over a period of time. The algorithm does not detect the moment of the fall itself like an accelerometer-based fall detection sensor would. A fall event is therefore by nature reactive, and should always be complemented with more proactive events such as “Not back in bed” at night. The sensitivity level determines the duration threshold, and a longer detected fallen state increases confidence that the situation warrants investigation.

An important source of false fall alarms is residents being static and in postures which can be mistaken for a fall, for instance when the resident is seated in an armchair or reclining position. Until now, customers have been recommended to add an “Exclusion Zone” around the chair to avoid this from happening. As the existing “Exclusion Zone” has not been sufficiently effective at cancelling fall events, Tellu now allows to instead define a “Safe Zone” over a couch, a chair or any area of the room in which fall detection specifically should not trigger. All existing Exclusion Zones are therefore automatically converted to Safe Zones. Meanwhile, as the Exclusion Zones affects all events, it should rather be used for rejecting unwanted motions in a designated frame such as TVs or windows. In short, this should reduce the unnecessary alarms related to zones already marked around armchairs and couches for instance.

Users with the technician role can configure such zones on a per-camera basis through “Edit mask” (“Users” in the left sidebar -> “Camera supervision” tab), using the same workflow as for other event masks such as for bed and door in TelluVision.

New Tool for Event Diagnostics

To enable Tellu’s Customer Success Managers to provide more extensive support, they can now propose to customers to enable a feature that record data at the time of the event detection. This includes metrics, mask coordinates, and bounding boxes for a few seconds before the event detection. The data sets do not contain any personal sensitive information and is stored on the camera itself. Access is restricted to those with camera configuration permissions in TelluCare. It is intended solely for investigating alarms and responding to questions and feedback from customers. Feedback from those investigation will support more efficient product improvements.

Experimental Events Available for Pilots

A set of experimental events are now available for piloting for relevant use cases. The events are under development, and therefore not available for all. They may change behavior, require reconfiguration or be removed in later updates based on customer feedback and market demand. Pilots must be approved by Tellu, and requires a clear objective and close collaboration.

The current experimental events include:

• Starting to get out of bed: When health personnel need an early warning before the resident leaves the bed, due to high risk of fall or restrictions from getting out of bed after surgery etc. Triggers based on motion, and can be adjusted to different sensitivity levels.

• Restless in bed: When health personnel would like to be alerted if the resident is moving frequently in bed, potentially indicating an issue. Triggers based on motion over a given period of time, and can be adjusted to different sensitivity levels.

• No motion in bed: When health personnel would like to be alerted if the resident is laying still in bed, potentially indicating an issue. Triggers based on motion over a given period of time, and can be adjusted to different sensitivity levels.

• Entering or leaving a zone: When health personnel would like to know when the resident enters or leaves a designated zone (e.g. chair) to timely coordinate care interventions and assistance with movement for instance. Triggers based on movement in and out of the zone.
