(3) Set detection rules.
Item Description
Sensitivity
Drag the slider to adjust detection sensitivity.
The higher the sensitivity level, the higher the detection rate of small motions, and the higher the
false alarm rate. Set based on the scene and your actual needs.
Object size
Drag the slider to set object size.

Object size: The ratio of the size of the detected object to the size of the detection area. An
alarm is triggered when the ratio reaches the set value. To detect motion of small objects,
you need to draw a small detection area separately.

Motion detection results of the current detection area are shown below in real time. The red
means motions that have triggered a motion detection alarm. The height of the lines indicates
the extent of motion. The density of the lines indicates the frequency of motion. The higher a
line, the greater the extent. The denser the lines, the higher the frequency.
(4) Set Suppress Alarm to avoid receiving the same alarms within a certain length of time (alarm
suppression time). For example, alarm suppression time is set to 5s, after an alarm is reported:
 If no motion is detected within the next 5s, new alarms can be reported after 5s when the alarm
suppression time is over.
 If motion is detected within the next 5s, the alarm suppression time recounts from the time of
the last alarm, and new alarms can be reported when the alarm suppressions time (5s) is over.

Grid detection
(1) Set grid detection areas (covered by grid), which is by default the whole screen.
