A
monitoring system and a method for detecting location of at least one person in a monitored area with a
monitoring system, which
monitoring system comprises at least one sensor arrangement (101, 201, 301, 302, 303, 304) comprising at least one sensor, measuring
electronics and a processor configured to process the sensor data, wherein the sensor is a
radar-based sensor, such as frequency-modulated continuous-wave
MIMO radar-based sensor, monitoring presence, location, movement and / or attitude of at least one person in the monitored area and, the
system determines with the at least one sensor arrangement presence, location and / or movement of at the least one person (402, 403, 404, 405) in the monitored area (200, 401), the
system sends information relating to presence, location and / or movement of the at least one person (402, 403, 404, 405) in the monitored area (200, 401) to a device (400, 500), such as a portable device, e.g. a mobile telephone or a tablet, wherein the device (400, 500) indicates the determined presence, location and / or movement of the at least one person (402, 403, 404, 405) in the monitored area in a map or a
floor plan of the monitored area.
