DEVICE, METHOD AND SYSTEM FOR MONITORING HUMAN PRESENCE IN AREA Russian patent published in 2017 - IPC G07C9/00 

FIELD: physics.

SUBSTANCE: to monitor the human presence in the area, the area is divided into, at least, two sub-areas, and for each sub-area of, at least, two sub-areas, at least, one detection line is defined in relation to the border of the respective sub-area. The detection line represents the input to the respective sub-area and / or exit from it. In the context of the monitoring it is determined whether the moving person enters the respective sub-area or exits from it, by using at least one detection line of the respective sub-area, and / or it is expected whether the moving person will enter the respective sub-area or will exit from it, by using at least one detection line of the respective sub-area. The area is subdivided into two sub-areas and a zone of observation.

EFFECT: it is possible to detect the human presence in these sub-areas without their monitoring, which greatly improves the private space feeling at the human presence in these sub-areas.
