Fall detection system for fall detection of a person, method for fall detection of a person and a computer program product for fall detection of a person

A fall detection system for performing a fall detection of at least one person in a sensing area, comprising

• at least one motion and/or presence detector configured to detect a motion or a presence of a person
• wherein the at least one motion and/or presence detector is operated in at least a first operating mode with first operating parameters and a second operating mode with second operating parameters, and
• a fall detector configured to detect a position or a presence of the person in the sensing area based on sensing signals from at least one motion and/or presence detector in the first or second operating mode,
• wherein the fall detector is configured to determine a fall risk by detecting a dwell time of a person sitting or lying down,
• wherein the fall detector is configured to activate the second operating mode if a high fall risk is determined by the fall detector wherein
• the motion and/or presence detector comprises a network of network devices configured to perform a RF based sensing in a sensing area wherein the network devices are distributed in the sensing area and are configured to communicate with each other based on RF signals, and further configured for:
• generating a RF signal by at least one network devices, detecting the RF signal from the network devices after a propagation through at least a portion of the sensing area,
• generating a sensing signal indicative of the RF signal, and
• wherein the fall detector is further configured to
• detecting a dwell time a person is sitting on a seating or lying down by the fall detector,
• activating the second operating mode if the dwell time exceeds a time threshold, and
• detecting a fall of the person in the second operating mode based on the RF sensing signal from the network device.
