6.2 Channel setup
Object detection
In the object mode all detected, contiguous cells are combined as one or more objects
according to their position to each other. The object size and not the total number of
activated cells will be compared to the defined number of maximum/minimum cells. Up
to 32 independent objects can be detected within the defined area simultaneously. The
following illustration shows the object detection mode:
Standard: According to the object volume of the rectangle the values of max. – and
min. object volume will be set to 250 per cent and 29 per cent respectively. This value
is a basic parameter based on operating experiences. However the installer has to find
out the optimal values according to the real scenery.
People recognition: The meaning and possible parameters are described in Detail-
Setup (Area options and Expert).
- 23 -
Objectvolume: Number of the cells that are enclosed by the
rectangle in the edit field (in the example on the left side 364).
The number is only information to estimate the object size.
This parameter has no further influence and will not be stored
in the sensor unit.
The definition of the object size can only be set by Object-
maximum/Objectminimum, described next.
Objectmaximum / Objectminimum: An object within the de-
fined area is only evaluated as an alarm, if the number of de-
tected cells is between the objectminimum and objectmax-
imum (in the example between 109 and 910 cells).
Exceeding the objectmaximum will start the timer ‚Max.
Break„, if selected.
Sensitivity: The entry of the parameter is performed as de-
scribed in Area Mode.
