Method and system for monitoring

A system for observing the presence, location and/or movement of one or more objects to be monitored in the area to be monitored, which system comprises at least one sensor, wherein a sensor or sensors are fitted into at least one of a floor, wall and/or ceiling, of the area to be monitored and wherein the sensor or sensors produce measuring information, by means of which measuring information the system is adapted to determine the presence, location and/or movement of an object,

• wherein:
• the system has a first mode and a second mode,
• the system is adapted to check in the first mode the state of health of the object in the area to be monitored,
• the system is adapted to function in the second mode as an intruder alarm monitoring the area to be monitored,
• wherein the system is adapted to use the same sensor in both the first mode for checking the state of health of the object in the area to be monitored and also in the second mode as an intruder alarm for monitoring the area to be monitored, and
• wherein the system is adapted to change the mode automatically, including:
• changing the mode of the area to be monitored to the first mode if the one or more objects to be monitored are located in the area to be monitored, and
• changing the mode of the area to be monitored to the second mode if the one or more objects to be monitored are located outside the area to be monitored, and
• wherein the first mode also includes the intruder alarm monitoring the area to be monitored by tracking the location of the object and determining if an unauthorized object enters the area to be monitored.
