Abstract

A monitoring device for monitoring inactive behavior of a monitored person in a monitored zone includes a plurality of monitoring sensors configured to record sensor data. The monitoring sensors are positioned in at least two spatially separated monitored subzones of the monitored zone. The monitoring device further includes an evaluation device including a model module and a test module. The model module produces a first inactivity model in a spatially anonymized manner for a first time period with reference to sensor data in the first time period. The model module produces a second inactivity model for a second time period. At least portions of the second time period are formed later than the first time period. The test module compares the first inactivity model and the second inactivity model and provides a change notification if there is a deviation between the first inactivity model and the second inactivity model.
