You can set different sensitivities for each region, with values ranging
from 0 to 100, and 30 to 70 is recommended.
Threshold
Detect the relation between the object and the region. The smaller the
threshold is, the easier the motion detection will occur.
Set different thresholds for each region, with values ranging from 0 to
100, and 1 to 10 is recommended.
Waveform graph
The red line indicates that motion detection is triggered, and the green
line indicates that it is not triggered.

Anti-Dither
The system records only one motion detection event within the defined
period. The value range is 0–100 s.
Enable Manual
Control Trigger
After you enable the function, the motion detection events that occur
when you control the PTZ manually will be excluded. In this way, you can
reduce the false alarm rate of such events.
