The parameters are the following:

- Repetition filters:
  - Free Flow/Motion filter captures: For a result to be considered valid, the last license plate read must not be among the last N recognized as valid. This filter is useful for traffic jams, where the cameras may be reading N license plates continually in a closed cycle.
  - Free Flow/Motion filter time (millis): Minimum time elapsed from the detection of the same license plate to it being accepted again in the system
- Minimum characters difference:The number of different characters to consider two plates different.
- Motion queue:The length of the images queue when MOTION mode is selected.
