3.3 PRESENCE DETECTION
Apart from the motion detection channels, it is possible to enable the presence
detection function. The difference between motion and presence is important:
The detection of motion does not necessarily imply presence of humans
(there may be objects moving in the room).
The non-detection of motion does not necessarily imply non-presence of
humans (they may be sleeping, for example).
The domotic system can hardly deal with this distinction. However, it is possible to
monitor subjects entering / leaving the room (and therefore determining whether there
is human presence inside or not) by making use of a set of motion detectors (one of
them acting as a master, and the others as slaves) and of state sensors at the doors
of the room.
To better illustrate how this functionality works, a practical example has been included
at the end of this section (3.2.3).
Once the "Presence Detector" has been enabled in the "Configuration" tab, a new
screen containing the corresponding parameters will show.
