1. Depending on the license type, go to the settings panel of the RR module (fast) or RR module (slow) object, which is created on the basis of the LPR channel object.
   
2. In the Number of streams field (1), enter the number of streams that the RR SDK will use in parallel computations. A value of 0 disables the calculating process paralleling for the license plate recognition 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.

3. In the Maximum track size (frames) field (2), enter the maximum number of frames for one track that will be processed by the RR SDK (the smaller the value, the faster the recognition result are given, but it is also be less accurate). The default value is 0. The number of frames is not limited.

   Note
   title Attention!
   If the LP recognition upon request is used (see Setting up the Camera of recognition upon request module), the Maximum track size (frames) must be equal to 1.

4. Set the Skip unrecognized LPs checkbox (3) to ignore the vehicles with unrecognized license plates.
5. By default, only license plates of the main country are recognized, which is specified in the settings panel of the LPR channel object (see Selecting the country and license plate recognition SDK). If it is also necessary to recognize license plates of additional countries, click the Select countries button (4) and in the Country selection window that opens, select the required countries.
   
6. If it is necessary to determine the speed by video, specify the appropriate camera settings (5). The specified parameters must correspond to the actually used camera and its mounting parameters.
7. To save the settings, click the Apply button (6).
