When a hotlist or permit is created or modified, you can specify the character set that applies to the license plates in the list based on a selected language, and what the ALPR Manager does if it detects a list with invalid characters (non-alphanumeric characters).

What you should know

To view detailed information about how many invalid entries were deleted or modified, you can also save the logs of the filtering process.


  1. From the Config Tool home page, click System > Roles, and then click the ALPR Manager you want to configure.
  2. Click the Properties tab.
  3. Under Plate filtering, select the types of characters to filter on from the Character set drop-down list (Latin, Arabic, or Japanese).
  4. In the Invalid plate number section, select one of the following options to specify how the ALPR Manager handles invalid records:
    Modify record
    Deletes any non-alphanumeric characters from the plate number. For example, the plate number “ABC#%3” becomes “ABC3”.
    Remove record
    Deletes the entire entry that contains invalid characters from the list.
  5. To log the filtering process, select the Log filtering option.
    The plate filtering logs will be saved in the AutoVu™ root folder: C:\Genetec\AutoVu\RootFolder.
  6. Click Apply.
