To configure the RoadAR RR vendor and model recognizer module, do the following:

1. Go to the settings panel of the RoadAR RR vendor and model recognizer recognizer object that is created on the basis of the LPR channel object.
   
   Set the Use GPU checkbox if you want to
   
2. From the drop-down list, select the type of neural network for recognizing vendors and models of RR vehicles:

   1. Lightweight for CIS countries (default);

   2. Medium-weight for CIS countries;

   3. Lightweight for other countries;

   4. Medium-weight for other countries.

3. In the Number of streams field, specify the number of streams that the SDK of the RR recognizer uses during parallel computing. The 0 value (default) disables parallelization during license plate recognition.
   

   Note
   title Attention!
   Increasing the number of streams during parallel computing also increases the load on the CPU. All changes are applied only after you restart Axxon PSIM.

4. Click the Apply button to save the settings.
