- The Visitors
Counter detection tool - counter detector can have a margin of error and is suitable for counting the average number of visitors.
- We cannot guarantee the correct operation of the
detection tool - detector with a fisheye lens.
|
To configure the Visitors Countercounter, do the following:
- Go to
the Detection Tools tab- the Detectors tab.
- Below the required camera,
click - click Create… → Category: Retail → Visitors
Counter- 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 |
|---|
| Object features |
| Video stream | Main stream | If the camera supports multistreaming, select the stream for which detection is needed |
| Other |
| Enable | Yes | By default, the |
detection tool | detector is enabled. To disable, select |
the value Counter detection tool | detector name or leave the default name |
| Decoder mode | Auto | Select a processing resource for decoding video. When you select a GPU, a stand-alone graphics card takes priority (when decoding |
with Nvidia NVDEC | with Nvidia NVDEC chips). If there is no appropriate GPU, the decoding will use the Intel Quick Sync Video technology. Otherwise, CPU resources will be used for decoding |
| CPU |
| GPU |
| HuaweiNPU |
| Number of frames processed per second | 25 | Specify the number of frames for the |
detection tool | detector to process per second. The larger the value, the greater the load on the CPU. The value must be in the range [0.016; 100] |

| Advanced settings |
| Frame size change | 640 | The analyzed frames are scaled down to a specified resolution (by default, |
1920 1920 pixels on the longer side) by default. The following algorithm is used: - If the longer side of the source image exceeds the value specified in the Frame size change field, it is divided by two.
- If the resulting resolution falls below the specified value, the algorithm stops and this resolution will be used further.
- If the resulting resolution still exceeds the specified value, it is divided by two until it is less than the specified resolution.
| Info |
|---|
| For example, the source image resolution is 2048*1536, and the specified value is set to 1000. In this case, the source resolution will be halved two times (512*384), as after the first division, the number of pixels on the longer side exceeds the specified value (1024 > 1000). If detection is performed on a higher resolution stream and detection errors occur, we recommend reducing the compression. |
|
| Number of people indoor | 0 | Enter the number of people indoor at the time you are configuring the |
detection tool| detector. The value must be in the range [0, 100000] |
| People indoor counter | Yes | By default, the parameter is disabled. The |
detection tool | detector generates events: Camera. Visitor access in the direction of "Entrance" and Camera. Visitor access in the direction of "Exit". If you also want to count visitors at the facility and generate an event when the threshold value is exceeded, select the Yes value |
| No |
| People indoor counter threshold | 10000 | Specify the threshold value of the number of people indoor. If this value is exceeded, the |
detection tool | detector generates an event. The value must be in the range [0, 100000] |
| Basic settings |
| Person size | 20 | Specify the area of the rectangle around a person as a percentage of the frame area. Note that the size is calculated based on the compressed frame size, not the original size of the video stream. The value must be in the range [1, 75]. | Info |
|---|
| It is better to specify the minimum size of a person graphically, the number in |
|
the the Person size field is a conditional value. |
Click the  Image Modified button in the preview window and |
specify specify the size of a person. To do this, move the anchor points of the rectangular area:  Image Modified
|
In the preview window, specify the detection area. The detection area is divided into two sectors—area 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 - 2—minus one to the visitors counter.
- Transition from area 2 to area
1—plus one - 1—plus one to the visitors counter.
You can configure the sectors, using the anchor points 
Image Modified or lines. To swap sectors, click inside one of them.

For convenience of configuration, you can "freeze" the frame. Click the  Image Modified button. To cancel the action, click this button again. Sectors are displayed by default. To hide them, click the  Image Modified button. To cancel the action, click this button again. |
To save the parameters of the detection tooldetector, click the Apply 
Image Modified button. To cancel the changes, click the Cancel 
Image Modified button.
Configuration of the Visitors counter is complete.
