Zusammenfassung:	The present invention relates to a device, system and method for reliable and fast fall detection. The device comprises a sensor input (11) for obtaining sensor data related to movement of a subject acquired by a body-worn sensor (20, 22, 61) worn by the subject, and a video input (12) for obtaining video data of the subject and/or the subject's environment. An analysis unit (13) analyzes the obtained sensor data to detect one or more signal features indicative of a potential fall of the subject and for analyzing, if one or more such signal features have been detected, the detected one or more signal features and/or related sensor data in combination with related video data to identify similarities between: changes of the related sensor data and/or the signal features over time; and changes of the video data over time. An output (14, 64, 65, 66) issues a fall detection indication if the level and/or amount of detected similarities exceeds a corresponding threshold.
