or disable a grid. Press MODE to select all of the grids for detection;

- Sensitivity
The 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 increased by 4%
increment.
- Area Threshold
<Area Threshold> means the motion alarm triggered level. If the
percentage of triggered grids from the 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, and then use
UP / DOWN keys to adjust the value. The value is increased by 1%
increment.
