Configuring the ALPR Manager role - Security Center 5.12

To manage reads, hits, and parking events, you must first configure the ALPR Manager role settings such as Genetec Patroller™ user groups, data retention periods, and so on, and assign an Archiver role to manage the ALPR images (captured by context cameras, ALPR cameras, and wheel imaging cameras) associated to the reads and hits.

1. From the Config Tool homepage, open the ALPR task, and click Roles and units.
2. Select the ALPR Manager that you want to configure, and then click Properties > General settings.
3. To change the location of the ALPR Manager’s Root folder, browse to a different folder on the local machine, or create a network folder.
   NOTE: If your computer is hosting more than one ALPR Manager, each ALPR Manager must have a different root folder.
4. If you have large hotlists or permit lists associated to individual Patroller units, turn on the Optimize root folder disk space option.
   IMPORTANT: If your Root folder is on a network drive, the Genetec™ Server service must be configured to run using a domain user and not a local user.
   Turning this option on enables the use of symbolic links to reduce the Root folder’s disk space, and optimizes the in-vehicle computer's file transfer performance. On both the server and client machines (requires administrator rights), open Windows Command Prompt, and then type the following:

   To enable symbolic links

   Type fsutil behavior set SymlinkEvaluation R2R:1

   To disable symbolic links

   Type fsutil behavior set SymlinkEvaluation R2R:0.

5. From the User group for Patrollers list, select the user group that contains the list of users who are allowed to log on to the patrol vehicles managed by the ALPR Manager.

   In Patroller Config Tool, if the Patroller Logon type is Secure name or Secure name and password, the Patroller user must enter the username and password configured in Security Center. If secure logon names are in use, you can see in Security Desk who was driving the vehicle when a read or a hit occurred.

6. In the Retention period section, specify how long ALPR-related data is kept:
   NOTE: The Retention period settings are only available for users that have the Modify ALPR Manager retention period privilege.

   Genetec Patroller™ route retention period

   Number of days the Patroller route data (GPS coordinates) is kept in the database.

   Hit retention period

   Number of days the hit data is kept in the ALPR Manager database.

   Hit image retention period

   Number of days the hit image data is kept by the linked Archiver role. The Hit image retention period cannot exceed the Hit retention period since a hit image is always associated with a hit.

   Read retention period

   Number of days the license plate reads are kept in the ALPR Manager database. The Read retention period cannot exceed the Hit retention period. If the read retention is lower than the hit retention, only the reads that are associated with hits are kept.

   Read image retention period

   Number of days the read image data is kept by the linked Archiver role. The Read image retention period cannot exceed the Read retention period since a read image is always associated to a read.

   Event retention period

   Number of days Patroller events (user logged on, logged off, and patrol vehicle positions) are kept in the ALPR Manager database.

   Parking occupancy retention period

   Number of days the parking occupancy data is kept in the ALPR Manager database.

   Parking zone data retention period

   Number of days the parking zone data is kept in the ALPR Manager database. This data includes parking session information, for example, parking session start times and state transitions, as well as information on the events that occur within the parking zone. The Parking zone data retention period cannot exceed the Read retention period.

   The default value for each setting it 90 days, and the maximum is 4000 days. Expired data does not appear in Security Center queries and reports (Hit reports, Read reports, and so on).

   NOTE: You cannot reduce the size of the database by reducing the retention period settings. The retention cleanup algorithm is meant to make space for new data. However, the size of the database file on disk will never shrink.
7. Click Apply.
8. Click Resources > Images saved to, and select the Archiver designated to manage the image data for the ALPR Manager.
   In a new installation, the default Archiver is automatically assigned to the ALPR Manager. If your system is only used for ALPR, you can keep the default configuration. If you also intend to manage video on your system, we recommend that you create separate Archiver roles for video management.

   In an upgrade scenario, an Archiver is automatically assigned to an ALPR Manager only if it is the only Archiver in the system, and only if the Archiver does not manage any video units.

9. Click Apply.
10. If you selected an Archiver, click Jump to () beside the Archiver name.
    This brings you directly to the Resources tab of the selected Archiver.
