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 generate an event. The value must be in the range [1, 20].
The recommended (default) value is 2.
Increasing the value can help eliminate false events, but increases the risk of skips. 
Decreasing the value can help reduce skips, but increases the probability of false events

Track retention time (sec)0.7Specify the time in seconds after which the object track is considered lost. This helps if objects in scene temporarily overlap each other. For example, when a larger vehicle completely blocks the smaller one from view. The value must be in the range [0.3, 1000]

      Note
      titleAttention!

      When you set up leveling rods, the following conditions must be met:

      1. the rods that are located at the same distance from the camera lens, must be of the same size;
      2. the feet of the rods must be located on the same surface (for example, floor);

      3. in complex scenes, we recommend adding more than three rods to increase the accuracy of the detection;

      4. 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);

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