Description
Set All

advantageous if you want to disable 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 disable motion detection.
Clear All
Lets you quickly clear all grid sections in the preview image.
Auto
By clicking the Auto button you can make NetDVR automatically detect areas
with noise (insignificant changes in individual pixels which should not be
regarded as motion) in the image, and automatically mark such areas as areas
in which motion detection should be disabled.
As the automatic detection is based on an analysis of a number of images, it
may take a few seconds from you click the
Auto
button to noisy areas are
detected and marked as areas in which motion detection should be disabled.
Note:
The automatic detection of noisy areas happens according to the noise
sensitivity setting specified in the
the automatic detection of noisy areas to work as intended, it is recommended
that you specify a noise sensitivity setting that matches your requirements
before you make use of the automatic detection feature.
Show Grid
With the
Show grid
check box selected (default), the preview image contains a
grid indicating the division of the preview image into selectable sections.
With the
Show grid
check box cleared, the grid in the preview image is
removed. This may provide a less obscured view of the preview image.
Selection of areas in which motion detection should be disabled takes place
the same way as when the grid is visible.
