Nurses choose which movements trigger an alert, and fixed severity levels rank them
Which movements matter for a patient is a clinical judgement, so nurses switch each movement on or off per patient. The list of movements was defined with clinical staff.
Ranking is different. When several alerts arrive at once, nobody has time to sort them. So every movement has a fixed severity, set once and applied to every patient, and the most serious alert shows first.

No alert goes unanswered
The app streamlined everyday operational tasks. Nurses could assign beds to patients, designate primary and secondary nurses with clear authority over each bed, and set up or extend shifts when needed.
One of the biggest issues was that a nurse might simply not be available to act, so the alarm had to keep moving until someone could. That's why the escalation flow was introduced. Accepting an alert means the nurse has seen the patient and takes responsibility. If they decline, or don't answer within 20 seconds, the alert goes to the secondary nurse, then to all nurses on duty, until it is answered.

Beyond the app
A separate web interface was also designed. An admin portal gave technicians full control, from camera placement to user management and movement databases. This added security, reduced shift interruptions, and lowered staff workload and stress.
I also built a design system that enabled seamless updates as needs evolved, making it easy to add features, maintain consistency, and deploy improvements without disrupting workflows.
