ParameterValueDescription
Object features
Record mask to archiveYesBy default, the recording of the mask to the archive is disabled. To record the sensitivity scale of the detection tool to the archive (see Displaying information from a detection tool detector (mask)), select the Yes value
No
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
No
NameCrowd Estimation VAEnter the detection tool name or leave the default name
Decoder modeAuto

Select a processing resource for decoding video. 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

Select a processor for the operation (see Selecting Nvidia GPU when configuring detection toolsdetectors)

Note
titleAttention!

If you specify other processing resource than the CPU, this device will carry the most of computing load. However, the CPU will also be used to run the detection tool.

Number of alarm objects1

Specify the number of objects at which an event occurs. The value must be in the range [0; , 10000]

Number of frames processed per second0.1017

Specify the number of frames for the detection tool to process per second. The value must be in the range [0.016; , 100]
