Selecting Nvidia GPU when configuring detectors

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

Attention!

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:

Parameter	Detector
Mode	Configuring the Equipment detector VL Configuring the Neural counter Configuring the License plate recognition RR Configuring License plate recognition RR—Parking Configuring the License Plate Recognition RR—Search in archive Configuring the Smoke detector Configuring the Fire detector Configuring the License plate recognition VT Configuring the Face detector VA Configuring the Face detector TV Configuring the Face detector VL Configuring the Neural classifier Configuring the Stopped object detector Configuring the Abandoned object detector VI Configuring the Abandoned object detector VI (Street) Configuring the Motion in area detector VI Configuring the Detector of atypical changes in the scene VI Configuring the Fight detector VL
Neural network mode	Configuring the Water level detector Configuring the Privacy masking Configuring the Equipment detector
Neural filter mode	Configuring the Neural tracker
Neural tracker mode	Configuring the Neural tracker
Detection mode	Configuring the Vehicle recognition RR Configuring the License plate recognition VT Configuring the Line crossing VI detector Configuring the Movement in prohibited direction VI detector Configuring the Motion in area detector VI Configuring the Detector of atypical changes in the scene VI Configuring the Fight detector VL Configuring the Person-based privacy masking Configuring the Meta-detector
Moving object filter mode	Configuring the Object tracker
Abandoned object filter mode	Configuring the Object tracker
Processing unit	Configuring the License plate recognition IV

You can change the order of the Nvidia GPU display using the CUDA_DEVICE_ORDER system variable (see Appendix 9. Creating system variable) by specifying the required value:

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

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

Run the command prompt as administrator.
In the command prompt, enter the Nvidia-smi query.
Press Enter.

The command prompt window displays the information about the installed Nvidia GPUs.
