Setting General Parameters

To set a situation analysis detection tool's general parameters, you must perform the following steps:

1. In the Detection Tools list, highlight a Situation analysis object (1) which offers a means of analyzing the situation in the field of view of the required video camera.
   
2. If you need to enable recording of video stream metadata, select Yes from the Record object tracking list (2).

3. If a video camera supports multistreaming, select the stream for which detection is needed (3). Selecting a low-quality video stream allows reducing the load on the Server.

4. If you require using the abandoned objects detection tool, set Abandoned Objects Detection to Yes (4).

5. To correct for camera shake, set Antishaker  to Yes (4).  This setting is recommended only for cameras that show clear signs of shaking-related image degradation.

6. If you require automatic adjustment of the sensitivity of scene analytic detection tools, in the Auto Sensitivity list, select Yes (4).

   Note

   Enabling this option is recommended if the lighting fluctuates significantly in the course of the video camera's operation (for example, in outdoor conditions)

7. In the Maximum height and Maximum width fields (4), enter the maximum height and width of a detectable object as a percent of the height of the video image frame. The values should be in the range [2, 100].

8. In the Alarm on Object's Max. Idle Time in the Area field (4), enter the maximum rest time of an object in seconds, after which the object is no longer detected. This value should be in the range [30, 1800].

   Note

   This setting is relevant for an abandoned object detection tool

   Note

   It is recommended to start by setting the value of this parameter at 10

9. In the Minimum height and Minimum width fields (4), enter the minimum height and width of a detectable object as a percent of the height of the video image frame. The values should be in the range [2, 100].
10. In the Period field (4), enter the time in milliseconds. This is the period of time after which the next video frame will be analyzed. This value should be in the range [0, 65535]. If the value is 0, each frame of the video image is analyzed.
11. In the Sensitivity: motion field (4), set the sensitivity for motion detection tools, on a scale of 1 to 80.

12. In the Sensitivity: abandoned object field (4), set the sensitivity for situational analytic tools for abandoned objects, on a scale of 5 to 30.

    Note

    These parameters depend on the lighting conditions and should be chosen empirically. It is recommended to start by setting the sensitivity at 20

The general parameters of the situation analysis detection tools are now set.
