When you configure detectors, select Nvidia GPUs one by one.

Note
titleAttention!
  • If only one Nvidia GPU is installed, select Nvidia GPU 0.
  • If several Nvidia GPUs are installed, select the graphics card on which you want to perform the detection process.
  • If you select an uninstalled Nvidia GPU, detection isn't performed.

The table lists the parameter names and detectors, configuring which you can select the required Nvidia GPU:

ParameterDetector
Mode

Neural network mode

Neural filter mode

Neural tracker mode

Detection mode
Moving object filter mode
Abandoned object filter mode

You can change the order of the Nvidia GPU

In the Axxon One software package, several types of detection tools process incoming data:

  1. Face detection.
  2. License Plate Recognition.
  3. Trackers.
  4. Pose detection.
  5. Equipment detection.
  6. Person-based privacy masking.
  7. Fire detection and smoke detection.
  8. Water level detection.
  9. Motion in area detection.
  10. Retail analytics:
    1. Queue detection.
    2. Visitors counter.
    3. Neurocounter.
  11. Service detection:
    1. Audio detection.
    2. Tampering detection.
  12. Embedded detection (IVA).

Detection tools are configured using the Detection Tools tab interface (within the Settings tab). To configure detection tools, it is necessary to have the appropriate user rights.

When configuring the detection, in the Mode field, select NVIDIA GPU one by one. 

If only one NVIDIA GPU is installed, in the Mode field select Nvidia GPU 0.

If more than one NVIDIA GPU is installed, in the Mode field select the video card which should be used for detection.

It is possible to change the order of NVIDIA GPUs display using the CUDA_DEVICE_ORDER system variable (see see Appendix 109. Creating system variable) by specifying the required value:

  1. The FASTEST_FIRST value numbers the GPUs from the most powerful card to the less powerful ones
    2. , i.e. 
  2. , that is, Nvidia GPU 0 is the most powerful card.
  3. The PCI_BUS_ID value numbers the GPUs according to the physical location of the cards in the PCI-E slots on the motherboard
    4. , i.e. 
  4. , that is, Nvidia GPU 0 is the card in the highest slot.

To find out information about the availability, quantity and numbering of NVIDIA Nvidia GPUs, do the following: 

  1. Run
    2. a command line
  2. the command prompt as
    3. an
  3. administrator.
  4. In the
    5. command line type the nvidia
  5. command prompt, enter the Nvidia-smi query.
  6. Press Enter.

The command line prompt window will display displays the information about the installed NVIDIA GPUs.

Note
titleAttention!

If you select a non-installed NVIDIA GPU in the Mode field, detection will not be performed.

For a video camera and its corresponding branch to appear in the detection tools list, the camera should be enabled in Axxon One.

Info
titleNote

By default, camera inputs that can be activated through an automatic rule are displayed on the list of detection tools.

In the viewing tile, on the right side of the detection configuration window, you can set visual parameters.

The indicator in the upper right corner displays the current time and recording status (see Time Display).

The default system setting to a detection event is not to trigger any response actions. To set system response, create an automatic rule or a macro (see Configuring Macros and Counters, Automatic Rules). Nvidia GPUs.
