8.4.2.4 Advanced Motion Detection

Different from traditional motion detection, advanced motion detection can filter out “noise” such as lighting changes, natural tree movements, etc. When an object moves in the selected area, it will trigger alarm.



Settings steps are shown as follows:

Step1: Selected effective region including Normal and Advanced;

Normal mode is effective for all detection areas;

Advanced methods will work in specific fields of view and require setting a preset.

Step2: Selected Detection Region and enable advanced motion detection;

Step3: Choose detection object. Check Human or Vehicle attribute, and the camera will alarm once detecting people or vehicle and triggering related events;

[General Settings]

Step4: Set Ignore Short-Lived Motion time. If you set the time, when the moving duration of an object is within the setting time, the alarm will not be triggered;

Step5: Set detecting sensitivity and object size limits;



Table 1. Description of the buttons
Parameters Function Introduction
Ignore Short-Lived Motion The alarm will not be triggered when the moving duration of an object is within the setting time. Off/1s/2s/3s/4s/5s are available.
Note: Ignore Short-Lived Motion time is to avoid false alarm caused by instant object movement within time setting.
Sensitivity Level 1~10 are available, the default level is 5. The higher the sensitivity, the easier it is for moving objects to be recorded in the results.
Note: The sensitivity can be configured to detect various movement according to different requirements. When the level of sensitivity is low, slight movement won’t trigger the alarm.

Trigger Mode

Set the desired mode of the trigger logic including General Mode and Bottom Mode.

General Mode: The alarm is triggered when the object's body roughly enters the detection area.

Bottom Mode: the alarm will be triggered as soon as the bottom of the object enters the detection area. Suitable for scenarios that require sensitivity to intrusion status/bottom detection preference.
Min. Size Draw the screen or input pixel number to set the minimum size of the detected object. When the object is smaller than this size, it will not be detected. The default minimum size is 3*3.
Max. Size Draw the screen or input pixel number to set the maximum size of the detected object. When the object is larger than this size, it will not be detected. The default maximum size is 320*240.
[Schedule Settings]

Step6: Set detection schedule;

Note: This part is the same as the regular schedule settings. You can refer to 8.4.2.2 Region Entrance.

[Alarm Action]

Step7: Set alarm action;

Note:
  • This part is the same as the regular alarm settings. You can refer to 8.4.2.1 Intrusion Detection.
  • If you enable External Output and choose Constant External Output Action Time, when object motion time is longer than the Ignore Short-Lived Motion time which you set in the selected regions, External Output Action alarm time will be always constant till the alarm is released.
