You can adjust various Motion Detection parameters in this section.

Sampling pixel interval [1-10]
This item is used to examine the differences between two frames. You can configure the interval of sampling
pixel. The default value is 1. For instance, if you set the interval to 3, the IP camera system will take one
sampling pixel from every 3 pixels of each row and each column in the detection area (see the figure below).
The alarm will be triggered when differences are detected.

Detection level [1-100]
You can configure the detection level for each sampling pixel. The detection level indicates up to what level the
camera will accept the differences between two sampling pixels. The smaller the value, the more minor motions
it detects. The default level is 10.

Sensitivity level [1-100]
The default level is 80, which means that if 20% or more sampling pixels are detected to be different, the
camera will detect motion. The higher the value, the more sensitive it is and the lower the red horizontal line in
the motion indication window.
