1. Go to the Abandoned objects detection tab.
   
2. In the Initial detection sensitivity [0, 1] field, specify the general sensitivity of the detection tool to detect abandoned objects in the range 0-1. The 0 value—no object will be detected. The 1 value—maximum sensitivity. The default value is 0.5.
3. In the Object visibility [0, 1] field, specify in fractions the sensitivity of the detection tool to detect barely visible, merging with the background objects in the range 0-1. The higher the value of the parameter, the less noticeable object can be detected. The recommended value (default) is 0.7.
4. In the The passenger traffic density [0, 1] field, specify the sensitivity of the object detection in conditions of intensive overlapping of the object by passing people in the camera FOV in the range 0-1. The default value is 0.99.
5. In the Minimum size of detected object (cm) field, specify in centimeters on one side the minimum allowable size of an object that you want to detect. You must specify the size of an object relative to the frame. Smaller objects don't trigger the detection tool. The default value is 5.
6. In the Maximum size of detected object (cm) field, specify in centimeters on one side the maximum allowable size of an object that you want to detect. You must specify the size of an object relative to the frame. Larger objects don't trigger the detection tool. The default value is 185.
7. In the Dead time field, specify the time interval in seconds, during which the occurrence of a repeated event is blocked. The default value is 0. 
8. In the Events intersection level field, specify the time interval, during which the events aren't processed when the results of successful detection coincide. The default value is 0.01.
9. In the Detection time (s) field, specify the time interval in seconds, after which an object is considered abandoned. The default value is 30.
10. Clear the Without person checkbox so that objects near people are also detected. By default, the checkbox is set, which means that objects near people are ignored.
11. Clear the Filter objects checkbox to disable the neural network filter of objects. By default, the checkbox is set, which means that the neural network filter is enabled.
12. In the Highlight and shadow filter field, specify the level of highlight and shadow filtering in the range 0.00-10 depending on the scene contrast, lighting variability, presence of shadows and highlights. You must select the value of the parameter empirically. The default value is 0.15.
13. In the Monotone filter field, specify the level of filtering of monotone and one-color triggers in the range 0.00-10, for example, spots on the floor. You must select the value of the parameter empirically. The default value is 0.15.
14. Clear the Background loading checkbox to disable the loading video background. By default, the checkbox is set.
15. Clear the Background saving checkbox so that the background isn't saved. By default, the checkbox is set, which means that the background of the video is saved for the time period specified in the Background saving period field. 
16. In the Background saving period field, specify the time period in seconds, for which the backgound of the video is saved. The default value is 0. 
17. In the Number of analysis analytics streams field, specify the number of video streams that are used for the operation of the neural network analytics. The default value is 4.
18. Click the OK button to save the settings of the detection tool. 
19. To save the changes, click the Apply button on the settings panel of the VideoIntellect abandoned objects detection object.
