To configure the Person-based privacy masking detector, do the following:
- Go to the
Detection Tools- Detectors tab.
- Below the required camera, click Create… → Category: Poses → Person-based privacy masking.
By default, the
...
detector is enabled and set to mask a person's head.
If necessary, you can change the
...
detector parameters. The list of parameters is given in the table:
| Parameter | Value | Description |
|---|
| Object features |
| Record mask to archive | Yes | By default, the recording of the mask to the archive is |
disabled record mask to the archive (see Displaying information from a detector (mask)), select the Yes value| disable, select the No value |
| No |
| Video stream | Main stream | If the camera supports multistreaming, select the stream for which detection is needed. Selecting a low-quality video stream allows reducing the load on the |

| Decoder mode | Auto | Select a processing resource for decoding video streams. When you select a GPU, a stand-alone graphics card takes priority (when decoding with NVIDIA NVDEC chips). If there is no appropriate GPU, the decoding will use the Intel Quick Sync Video technology. Otherwise, CPU resources |

| Advanced settings |
| Number of measurements in a row to trigger detection | 3 | Specify the minimum number of frames on which the |
detection tool | detector must detect objects to generate an event. The value must be in the range [1, 20] |
| Segmenting network file |
Select
| Specify a neural network file. The standard neural networks for different processor types are located in the C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroSDK directory. You don't need to select the standard neural networks in this field, the system will automatically select the required one. If you use a custom neural network, specify the path to the file. |
infoNote | To ensure the correct operation of the neural network | - You cannot specify the network file in Windows OS. You must place the neural network file locally, that is, on the same server where you install Axxon One.
- For correct neural network operation on Linux OS, place the corresponding file

By default, the entire frame is a detection area.
To save the parameters of the detection tooldetector, click the the Apply 
Image Modified button. To cancel the changes, click the Cancel 
Image Modified button.
Configuring the Person-based privacy masking is complete.
Selected body parts of all persons will be are hidden in the frame. For a user group with limited permissions to view masked video (see Roles Role), the mask is displayed on the video image of the selected camera in the Detection Tools Detectorsand Hardware sections, on the layouts, in the archive, and when exporting. For the admin user group, the mask is displayed only on the video image of the selected camera in the Detection Tools Detectorsand Hardware sections, and when exporting, if the View masked video checkbox is clear (see Standard video recordings export Export).
