• Country module: Clear or select country modules to view only LPR events linked to a license plate from a particular country, state, or region
• LPR camera: Select one or more of the available LPR cameras to view only LPR events for those cameras
• Match list: Select one or more license plate lists to view only LPR events generated by those lists
