Activating the license for the Fight detector VL in Linux OS

To configure the Fight detector VL, do the following:

  1. Go to the Detection Tools tab.

  2. Below the required camera, click Create… → Category: Other → Fight detector VL.

By default, the detection tool is enabled and set to generate events when a fight is detected in the scene.

If necessary, you can change the detection tool parameters. The list of parameters is given in the table:

ParameterValueDescription

Video streamMain streamIf the camera supports multistreaming, select the stream for which detection is needed
Other
EnableYesBy default, the detection tool is enabled. To disable, select the No value

Decoder modeAutoSelect 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 will be used for decoding

Ignore time (sec)30

Specify the time interval in seconds during which events won't be 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, you can specify the detection areas using the anchor points (see Configuring a detection area).

Note

  • For convenience of configuration, you can "freeze" the frame. Click the button. To cancel the action, click this button again.
  • The detection area is displayed by default. To hide it, click the button (see Configuring a detection area). To cancel the action, click this button again.

To save the parameters of the detection tool, click the Apply  button. To cancel the changes, click the Cancel  button.
