By default, the Close-standing people detection triggers detector generates an event when "skeleton" bounding boxes around people collide. 

Info
title Note
Bounding boxes are not displayed in the interface. They are usually a bit larger than the "skeletons" dimensions.

If necessary, you can change the detection tool detector parameters. The list of parameters is given in the table:

      When you set up leveling rods, the following conditions must be met: the rods that are located at the same distance from the camera lens

12. • must be of the same size; the feet of the rods must be located on the same surface (for example, floor); in complex scenes, we recommend adding more than three rods to increase the accuracy of the detection; in the parts of the frame where the lens vertical distortion is observed, the rods must be parallel to the nearest vertical objects (for example, door

,

13. • or wardrobe); for portrait-oriented scenes (such as corridor, shopping aisle, warehouse aisle, and so on), the arrangement of the rods must form triangles.
