Configuring the parameters of the detection tool

...

Basic settings
Number of measurements in a row to trigger detection2

Specify the minimum number of frames with the corresponding pose or behavior for the detection tool to triggergenerate an event. The value must be in the range [1, 20].
The recommended (default) value is 2.
Increasing the value can help eliminate false alarmsevents, but increases the risk of skips. 
Decreasing the value can help reduce skips, but increases but increases the probability of false alarmsevents

To save the parameters of the detection tool, click the Apply button. To cancel the changes, click the Cancel button.

...

If camera angle doesn't meet the requirements (see Video stream and scene requirements for the Pose Detection and its sub-tools), this can result in false alarms.If there are false alarmsevents. In this case, we recommend configuring the frame perspective using the leveling rods. 

...

  1. In the preview window, click the button.
  2. Specify the size of the same person in different parts of the frame by eye. To create a leveling rod, left-click the video image to add two anchor points. You must set at least three leveling rods. The size of the leveling rod must be about the average height of a person at this part of the frame. You can resize the rod by stretching its anchor points . You can move it on screen by dragging and dropping.

    Note
    titleAttention!

    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, 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, wardrobe);

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