<p>For monitoring presence of persons in an area, the area is subdivided into at least two sub-areas and, for each of the at least two sub-areas, at least one detection line is defined with regard to a boundary of the corresponding sub-area. The detection line marks an entry to and/or exit from the corresponding sub-area. Within the scope of the monitoring, it is detected whether a moving person is entering or exiting the corresponding sub-area by use of the at least one detection line of the corresponding sub-area and/or whether the moving person is expected to enter or exit the corresponding sub-area by use of the at least one detection line of the corresponding sub-area.</p> |
