Name Description
Show grid
Lets you toggle the grid on and off. Toggling the grid off may
provide a less obscured view of the preview image; selection of
areas which should be excluded from motion detection takes place
the same way as when the grid is visible. When on, the preview
image will be divided into small sections by a grid. To define areas
which should be excluded from motion detection, drag the mouse
over the areas in the preview image while pressing the mouse
button down. Left mouse button selects a grid section; right mouse
button clears a grid section. Selected areas are highlighted in blue.
Include All
Lets you quickly select all grid sections in the preview image. This
can be useful if you want to exclude motion detection in most areas
of the image, in which case you can simply clear the few sections in
which you do not want to exclude motion detection.
Exclude All Lets you quickly clear all grid sections in the preview image.
Sensitivity
Determines how much each pixel must change before it is regarded
as motion. With a high sensitivity, very little change in a pixel is
required before it is regarded as motion. Areas in which motion is
detected are highlighted in green in the preview image. Select a
slider position in which only detections you consider motion are
highlighted. The more you drag the slider to the left, the more of the
preview image becomes highlighted. This is because with a high
sensitivity even the slightest change in a pixel will be regarded as
motion. As an alternative to using the slider, you may specify a
value between 0 and 256 in the field next to the slider to control the
sensitivity setting.
Motion
Adjust the Motion slider so that motion detection is only triggered
by the required level of motion. The selected motion level is
indicated by the black vertical line in the Level bar above the
sliders. The black vertical line serves as a threshold. When motion
is above (to the right of) the selected level, the bar changes color
from green to red, indicating a positive motion detection.
Alternatively, specify a value between 0 and 10000 in the field on
the left to control the motion setting.
The more you drag the slider to the left, the more positive motion
detections you see because less change will be needed to trigger a
positive motion detection. The number of positive motion detections
may also affect the amount of video you record, the amount of
notifications you receive, etc.
Keyframe Only
If you want motion detection to take place only on keyframes of the
video stream to reduce the system resources used on motion
detection, select Keyframe only.
