Glossary

A notification sent when Signal Homecare detects something unusual in the home. Alerts include a clear explanation of what was detected and why.

The order in which family members are contacted when something unusual happens. If the first person doesn't respond, the alert passes to the next.

See "normal routine". Signal Homecare learns what's typical for the home over its first few weeks, then uses this understanding to spot changes. Sometimes called a baseline in technical contexts.

A way of scrambling data so that only authorised people can read it. Signal Homecare uses the same standard of encryption as major banks.

The second phase after Signal Homecare finishes learning. During this period, you can tell Signal Homecare if an alert was incorrect, helping it improve its accuracy before going fully active.

The small device installed in the home that connects all the sensors and communicates with the Signal Homecare system. About the size of a paperback book.

What a typical day looks like in the home — when someone usually gets up, uses the kettle, moves between rooms, and so on. Signal Homecare learns this automatically.

A sensor that detects whether someone is in a room. Used in bathrooms and bedrooms to understand daily patterns without cameras.

How easily Signal Homecare raises an alert. Higher sensitivity means more alerts (including some that may not be important). Lower sensitivity means fewer alerts but only for more significant changes.

A plug adapter that can tell when an appliance is being used. Signal Homecare uses these on kettles and TVs to understand daily routines.
