Video stream and scene requirements for the Visitors Countercounter |
| Note | ||
|---|---|---|
| ||
|
To configure the Visitors counter detection tool, do the following:
...
Click the 
button and specify the size of a human (4). You can do this by dragging the anchor points of the rectangular area. You can also specify the size of a human manually by entering into the Human size field (9) the area of the rectangle around a human as a percentage of the frame area. Consider that to calculate the size, the size of the compressed frame is taken into account (7) and not the original size of the video stream. The value should be in the range [1; 75].
| Note | ||

When specifying the size of a human, consider the Image requirements for the Visitors Counter. |
...
- Go to the Detectors tab.
- Below the required camera, click Create… → Category: Retail → Visitors counter.
By default, the detector is enabled and set to count the number of people in a queue.
If necessary, you can change the settings of the detector parameters given in the table:
| Parameter | Value | Description |

In the preview window, specify the detection area. The detection area is divided into two sectors—area 1 and area 2. The transition from area 1 to area 2 is the visitor's passage in the "Exit" direction. The transition from area 2 to area 1 is the visitor's passage in the "Entrance" direction. If the People indoor counter parameter is enabled:
- Transition from area 1 to area 2—minus one to the visitors counter.
- Transition from area 2 to area 1—plus one to the visitors counter.
You can configure the sectors, using the anchor points 
or lines. To swap sectors, click inside one of them.
