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.

NOTE: If you set this item to <N/C> but did not install any device to the unit,

until this item is changed to <N/O>, <OFF> or, install a device to the unit.
