Summary

By deploying Internet of things (IoT) devices, smart home makes use of IoT technologies to collect ambient information, detect abnormal events at home and report to relevant personnel or institutions.

In this Recommendation the term "abnormal event" is intended as meaning a human health injury event at home. Examples of abnormal events at home include, but are not limited to, coughing, dyspnoea, falls, headache, quiescent behaviour, sleep apnoea, stroke, transient ischemic attacks.

Such a smart home system aims to reduce injuries and casualties at home. Various products have emerged in this field. However, the lack of standards could limit the abilities of vendors to meet the rising demands across the globe, such as lower false alarm rates, more convenient deployment, better handling of privacy concerns, etc. In order to ensure the system quality, Recommendation ITU-T Y.4220 specifies the requirements and capability framework of the abnormal event detection system (AEDS) for smart home.
