Configuring Free-Flow general settings - Security Center 5.12

To use AutoVu™ Free-Flow, you must configure general settings which define how the system handles license plate reads, and how Free-Flow works with Pay-by-Plate Sync.

1. From the Config Tool homepage, click System > Roles.
2. Select the ALPR Manager you want to configure, and then click the Properties tab.
3. Select Free-Flow.
4. Configure plate matching.

   Match tolerance threshold

   This value indicates the number of single-character differences between entry and exit plate reads that are still considered a match. Setting the value to 0 is equivalent to an exact match.

   IMPORTANT: Setting this value too high may cause plate reads to be associated with the wrong vehicle. The default value is 1.

5. Select which parking occupancy data to use.
   Use independent occupancy:

   OFF

   Security Center tracks parking occupancy using parking sessions from the Free-Flow Multi-tenant plugin.

   ON

   Security Center uses an independent counter to track vehicles entering and exiting the parking lot.

6. (Optional) Configure Pay-by-Plate Sync settings if you are using a third-party payment provider.

   Server

   Enter the IP address of the machine on which Pay-by-Plate Sync is installed.

   Port

   Enter the port number for the Pay-by-Plate Sync connection (default: 8787).

7. (Optional) Configure XML export settings if you are sending plate reads to a third-party system.

   XML export folder

   Specify the export folder for Free-Flow XML data.

   Include vehicle images with export

   By default, vehicle images are not included with exported XML files.

   NOTE: Including vehicle images increases the size of the XML export file.

   Export occupancy

   Export parking zone occupancy data to a separate XML file.

   NOTE: A single XML file is exported for all parking zones. This file is overwritten once per minute.

   The following is an example of an occupancy XML file:

   Code

   <?xml version="1.0" encoding="UTF-8"?>
   <OccupancyExport>
     <RoleId>8817e652-a9ca-4d06-81d7-8db93b5e3819</RoleId>
     <RoleName>ALPR Manager</RoleName>
     <ParkingOccupancies>
       <Occupancy>
         <Capacity>100</Capacity>
         <ParkingZoneId>293b9997-19ac-4fd9-99a4-c713fbbe1b96</ParkingZoneId>
         <ParkingZoneName>P1</ParkingZoneName>
         <TimestampUtc>2017-04-05T20:15:00Z</TimestampUtc>
         <Vehicles>5</Vehicles>
         <Violations>1</Violations>
         <EnforcedVehicles>0</EnforcedVehicles>
       </Occupancy>
       <Occupancy>
         <Capacity>200</Capacity>
         <ParkingZoneId>9dab3ef5-197f-4a33-87ae-e85dfa01c0b2</ParkingZoneId>
         <ParkingZoneName>P2</ParkingZoneName>
         <TimestampUtc>2017-04-05T20:15:00Z</TimestampUtc>
         <Vehicles>4</Vehicles>
         <Violations>0</Violations>
         <EnforcedVehicles>0</EnforcedVehicles>
       </Occupancy>
     </ParkingOccupancies>
   </OccupancyExport>

   

   Export violations

   When a vehicle is in violation, vehicle information is exported as a separate XML file.

   The following is an example of a violations XML file:

   Code

   <?xml version="1.0" encoding="UTF-8"?>
   <InLotViolation>
     <ParkingZoneName>P1</ParkingZoneName>
     <ParkingRuleName>Default parking rule</ParkingRuleName>
     <ParkingZoneId>293b9997-19ac-4fd9-99a4-c713fbbe1b96</ParkingZoneId>
     <SessionId>e6abdbb3-3b1a-e711-8b70-001018e35f7c</SessionId>
     <ParkingRuleId>09e29d39-83da-4cdc-81cc-0191833cb9a6</ParkingRuleId>

     <TimestampUtc>2017-04-05T20:09:57.7919418Z</TimestampUtc>
   </InLotViolation>

   

   Export completed sessions

   When a vehicle exits the parking lot, the parking session information is exported as a separate XML file.

   The following is an example of a completed sessions XML file:

   Code

   <?xml version="1.0" encoding="UTF-8"?>
   <ParkingSessionCompleted>
     <ParkingZoneName>P1</ParkingZoneName>
     <ParkingRuleName>Default parking rule</ParkingRuleName>
