If necessary, you can change the detector parameters. The list of parameters is 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 detector is enabled. To disable, select the No value | |||
| No | |||||
| Name | Fight detector VL | Enter the detector name or leave the default name | |||
| Decoder mode | Auto | Select a processing resource for decoding video streams. When selecting a GPU, a stand-alone graphics card takes priority (decoding with Nvidia NVDEC chips). The decoding uses the Intel Quick Sync Video technology if there is no appropriate GPU. Otherwise, CPU resources are used for decoding | |||
| CPU | |||||
| GPU | |||||
| HuaweiNPU | |||||
| Type | Fight detector VL | Name of the detector type (non-editable field) | |||
| Basic settings | |||||
| Detection mode | CPU | Select the processor for the detector operation (see Selecting Nvidia GPU when configuring detectors) | |||
| Nvidia GPU 0 | |||||
| Nvidia GPU 1 | |||||
| Nvidia GPU 2 | |||||
| Nvidia GPU 3 | |||||
| Detection threshold (starting with Detector Pack 3.14) | 50 | Specify the threshold value that recognizes behavior as a fight. The higher the value, the greater the chance of detecting weak signs of a fight. The value must be in the range [1, 100] | |||
| Ignore time (sec) | 30 | Specify the time interval in seconds during which events aren't processed after successful detection. The parameter is necessary to reduce the total number of events since the analysis is performed continuously, and the duration of real events can be several seconds. You must select the required value empirically. The value must be in the range [0, 9999] | |||
In the preview window, set the area for object detection. You can set configure the detection area by moving the anchor points 
(see Configuring a detection area).
