Consider the following recommendations to exclude false alarms of Situation Analysis Detection Tools:
- Configure the Tracker object object iteratively and check operation quality in each iteration.
- The parameters that affect operation quality most are: Minimum size, Maximum size (see Set the Minimum and Maximum Object Size for Detection), and Sensitivity (see Setting General Parameters).
- It is recommended to use Auto sensitivity mode to ensure quality of the Tracker operation in changing lighting conditions.
- If lighting is stable, it could be reasonable to adjust the Sensitivity value manually. Set Sensitivity value about 35 to detect objects with low contrast or about 15 to detect contrast object.
- Minimum size is to be selected so that it is a little less than typical object size on the image.
- Maximum size is to be selected so that it is a little greater than typical object size on the image, considering that the object can be joined with its shadow.
- Lowering the Time of Object in DB allows excluding triggering of false static objects, while setting it to a higher value could allow not breaking off alarms for overlapping or temporarily disappearing objects in some cases.
