• Area Threshold
<Area Threshold> indicates 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 seven grids
are motion detected.
Click UP / DOWN arrow keys to adjust the value. The value is
indicated in 4% increment.
Note that every time you have changed the value, remember to click
on “Apply” key to make the change take effect.
After the change(s) have been made (remember to click on “Apply”),
click to start detecting; click to stop detecting; click
to select all grids; and click to clear all selected
grids.
