7.3 Configuring Motion Detection Characteristics
A trigger is initiated each time the camera detects motion. Motion is defined as a percentage
(size) of the pixels in the detection area (mode) changing by a specific threshold (sensitivity). If
you are unsure what to enter for size or sensitivity, use the default values.
mode Sets the motion detection software to either include or exclude the
interior area of the given window. Included versus excluded areas
are cumulative. The motion detection algorithm will use every
pixel that is in an included window but not in any exclude
windows.
Exclude windows are drawn in red. Include windows are drawn in
blue. If the image is streaming, include windows will flash green
when motion is detected in that window.
The motion “Detection area” is shown as the white area in the
picture above (a normal picture would show instead of the
background colors shown in the example.)
sensitivity Specifies how much an individual pixel value must change in order
for the change to be considered significant. This setting works
together with size. Enter a value from 0 to 255, or the word AUTO.
The lower the number, the higher the sensitivity (and thus the more
likely something will be considered motion).
size Specifies the fraction of total pixels in the detection window that
must change by the sensitivity threshold in order for the change to
be interpreted as motion. Enter a value of 0.01 (1%) to 1.00
(100%). For example, entering 0.75 means that 75% of the pixels
in the window must change.
