Abstract
The movement of persons is indicated at least at two predefined locations in a building with motion detectors intended for monitoring each location and fastened to the building. By means of the detections, the movement of each person is detected from a predefined initial location to a predefined destination location in a predefined time without raising an alarm if the detected locations of the person form a line of predefined consecutive locations. Otherwise, an alarm is raised.
Claims10
A method for guarding one or more persons inside a building, the method comprising
- directing, by means of at least two motion detectors fastened to the building, into a room being monitored at least two non-superimposed beams, at least one of which extends in a width of at most dozens of centimeters across the room being monitored;
- detecting the movement of each person at least at two separate locations defined by the beams;
- observing the movement of each person by means of the detections in a predefined time without raising an alarm, if the detected locations of the person form a line of predefined consecutive locations from a predefined initial location to a predefined destination location;
- raising an alarm if this is not the case;
- and
- raising an alarm if the person being monitored is not detected twice successively at the destination location.
A system for guarding one or more persons inside a building, wherein the system comprising
- at least two motion detectors and a control centre;
- each motion detector being fastened to the building and configured to direct into a room being monitored at least two non-superimposed beams in such a manner that at least one of the motion detectors is configured to extend its beam in a width of at most dozens of centimeters across the room being monitored;
- each motion detector being configured to indicate the movement of each person at least at two separate locations defined by the beams;
- and
- the control centre being configured to observe the movement of each person by means of the detections in a predefined time without raising an alarm, if the detected locations of the person form a line of predefined consecutive locations from a predefined initial location to a predefined destination location,
- the control centre being configured to raise an alarm if this is not the case, and
- the control centre being configured to raise an alarm if the person being monitored is not detected twice successively at the destination location.
