| Name | Close-standing people detector | Enter the detector name or leave the default name |
| Type | Close-standing people detector | Name of the detector type (non-editable field) |
| Basic settings | ||
| Distance sensitivity | 2 | Specify the distance between people in meters at which the detector must generate an event. An event is generated if the distance between people in the frame is equal to or less than the specified distance. The value must be in the range [0, 20] |
| Leveling rod length | 1.7 | Specify the average height of a person in meters, according to which the leveling rods are set. The value must be in the range [0, 3] |
| Number of measurements in a row to trigger detection | 4 | Specify the minimum number of frames with close-standing people for the detector to generate an event. The value must be in the range [1, 100]. Increasing the value can help eliminate false event, events but increases the risk of skips. Decreasing the value can help reduce skips, but increases the probability of false events |

Configuring the frame perspective perspective
If you want to change the distance that must generate an event, you must configure the frame perspective:

For portrait-oriented scenes (such as corridor, shopping aisle, warehouse aisle, and so on), we recommend configuring the perspective in any case. |
- In the preview window, click the
- the
button. - Click in the preview window.
- Select Leveling rod.
- Specify the size of the same object in different parts of the frame by eye:
- To create a leveling rod, left-click the video image to add two anchor points.
Set at least three calibration rods. The lower anchor points of any three rods must not be located on the same line (horizontal, vertical, slanting, and so on).
- 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 points
. You can move it on screen by dragging and dropping.
Note title Attention! 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 or wardrobe);
- for portrait-oriented scenes (such as corridor, shopping aisle, warehouse aisle, and so on), the arrangement of the rods must form triangles.
Info title Note - For convenience of configuration, you can "freeze" the frame. Click the the
