It is possible to configure the filtering of the recognized LP numbers according to a number of criteria.

By default, the recognized numbers that have been filtered are not saved in the database. In order for the filtered numbers to be saved in the database, it is necessary to set the 0 value for the SaveFilterToDB parameter (for details, see Registry keys reference guide, for more information about working with the registry, see Working with Windows OS registry).

To configure the filtering of the vehicle plates, do the following:

  1. Go to the LPR channel object settings panel, corresponding to the activated module (see Activating the software module used for identifying the plates).
  2. Go to the Saving settings tab (1).
  3. In the Min. number of characters in LP field (2), specify the minimum number of characters in the recognized number.
  4. In the Min. recognition quality, % field (3), specify the minimum recognition quality in percent.
  5. In the Min. time of LP repetition, s field (4), specify the minimum time in seconds of number repetition in the video in the range 0-3600.  
  6. Click the Apply button (5) to save the settings.

Setting up the filtering of the recognized LP numbers is completed.
