You can send different sound files to the patrol vehicle's MobileClient folder using the Security Center updater service.
What you should know
The sound files for permit hits, overtime hits, and plate reads must be in the default Sounds folder for Genetec Patroller™ to be able to play them.
After sending the files to the MobileClient folder, you can manually move the files to the Sounds folder if you choose, but you can also zip your sound file so that Windows extracts it to the Sounds folder automatically.
Procedure
Results
Patroller restarts after installing the update, and now uses the new sound file for your chosen ALPR event.
