Noise Sensitivity Slider - Adjusts the noise sensitivity level of individual
picture elements (pixels). The noise sensitivity level determines when the
change in light intensity and color (light change) of individual pixels
should be considered noise (i.e. an insignificant change) and when it
should be considered motion (i.e. a significant change). In the live
updating camera image, the pixels where motion has been detected are
displayed with the selected motion color (green by default).
To get an idea of how this works, try dragging the slider to high and
watch how the whole image turns green. Drag the slider back to the
optimal position, i.e., where only the pixels affected by significant light
changes are shown with the motion color.
Motion Sensitivity Slider - Adjusts the sensitivity to motion. This controls the
alarm threshold and thereby determines the minimum size of an object
that will generate an alarm. Drag the slider until the alarm threshold
indicator is at the optimal position.
Note: Some video cameras generate undesired noise in poor light condi-
tions. To avoid generating undesired alarms, it may be necessary
to reduce the noise sensitivity or to improve the lighting at the
viewed location.
