Activating the license for the PPE detection Equipment detector VL in Linux OS

To configure the PPE detection VL, do the following:

...

ParameterValueDescription
Object features
Record objects trackingYesThe metadata is recorded to the database by default. To disable the parameter, select the No value
No
Video streamMain streamIf the camera supports multistreaming, select the stream for which detection is needed
Other
EnableYesThe detection tool is enabled by default. To disable the detection tool, select the No value
No
NamePPE detection VLEnter the detection tool name or leave the default name
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
CPU
GPU
HuaweiNPU
Minimum authenticity threshold 90Specify the minimum level of recognition accuracy for creating a track. You must select the appropriate value empirically. The higher the value, the fewer objects will be detected, but at the same time the recognition quality will be higher. The value must be in the range [1, 100]
ModeCPU

Select a processor for the neural network operation (seeHardware requirements for neural analytics operation, Selecting Nvidia GPU when configuring detectors).

Nvidia GPU 0
Nvidia GPU 1
Nvidia GPU 2
Nvidia GPU 3
Number of frames processed per second1

Specify the number of frames that the neural network will process per second. If the detection tool recreates the track for the same object, which leads to incorrect counting, increasing the value can help eliminate false positives. The higher the value, the more accurate the tracking, but the higher the CPU load. The value must be in the range [0.016; 100].

Note
titleAttention!

To operate the detection in a "gateway", we recommend using the standard settings of the detection tool: 1 FPS and 10 FPS for output (see Functions of the PPE detection Equipment detector VL).


Number of measurements in a row to trigger detection10Specify the minimum number of frames with a violation for the detection tool to generate an event. The value must be in the range [2, 50]
One detection per trackYesBy default, the detection tool generates an event for each element of equipment once per track existence. If you want the detection tool to generate an event for each equipment violation, select the No value
No
TypePPE detection VLName of the detection tool type (non-editable field)

By default, the entire frame is the detection area. In the preview windowIf necessary, you can specify reduce the rectangular detection areas area in the preview window using the anchor points  (see Configuring a detection area).
