Sensitivity
This item is used to set the sensitivity of detection grids for the camera. A
greater value indicates more sensitive motion detection. A motion alarm will
be triggered, once the amount of motion detected exceeds the Threshold
value
Move the cursor to <Sensitivity> and press ENTER, and then use UP /
DOWN keys to adjust the value. The value is indicated in 4% increment.
Area Threshold
<Area Threshold> means the motion alarm triggered level; if the percentage
of triggered grids to total detection area is greater than the set value, the
motion alarm will be triggered.
For example, if 10 grids are selected and the < Area Threshold > value is 70%,
the motion alarm will be triggered when 7 grids are motion detected.
Move the cursor to < Area Threshold > and press ENTER, then use UP /
DOWN keys to adjust the value. The value is indicated in 1% increments.
