Setting up the Archiver role for LPR - Security Center 5.7 SR1

Security Center Installation and Upgrade Guide 5.7 SR1

Security Center 5.7 SR1

To complete the configuration of an LPR Manager, you must link an Archiver to the LPR Manager to store the LPR images (captured by context cameras, LPR cameras, and wheel imaging cameras) that are associated to the reads and hits.

What you should know

Best Practice: We do not recommend a single Archiver for managing both LPR and video data because the settings optimized for storing LPR images are different from the ones for storing video. If you need to perform both functions on your system, we recommend that you create separate Archiver roles, each handling only one function.

If you already have an Archiver role that is available (not managing video), you can use it and skip the role creation steps.

If you are unable to have separate Archiver roles, you can manage both LPR and video data with the same Archiver. Note that by default, the Archiver deletes the oldest files when its disks become full. This means that LPR images might be deleted before their retention period is over. This does not affect LPR metadata or the protected events and images.


  1. From the Config Tool home page, open the Video task.
  2. Click the menu button beside Video unit (), and then click Archiver ().
    The role creation wizard window opens.
  3. On the Specific info page, set the following fields, and then click Next.
    This parameter appears only if you have more than one server in your system. If the LPR Manager is hosted on its own server, we suggest using the same server to host the linked Archiver role. If it is an upgrade from Security Center 5.5 or earlier, make sure you have enough free space on disk to store the LPR images. We recommend using a server where it is possible to configure the Archiver role with its dedicated local disk or disk partition.
    Database server
    Name of the SQL Server service (default=(local)\SQLEXPRESS). If the Archiver is hosted on the same server as the LPR Manager, we recommend using the same database server for both.
    Name of the database instance (default=Archiver). We suggest using LPR_Archiver to differenciate it from video archive databases.
  4. On the Basic information page, set the following fields, and then click Next.
    Entity name
    Name of the Archiver role (default=Archiver).

    We suggest using LPR_Achiver to differentiate it from the Archiver role for video.

    Entity description
    Role description. If this Archiver role is shared by many LPR Manager roles, we suggest that you list them here.
    This parameter appears only if you have partitions defined in your system. Make sure you create this Archiver in the same partition as the LPR Manager it is linked to. Only users who have access to the selected partition can view the LPR data managed by these roles.
  5. Verify that the information displayed in the Creation summary page is correct, and then click Create.
  6. Click Close.
  7. From the Archiver role's Resources tab, configure the archive storage settings.
    IMPORTANT: Make sure you are not using the same disk as another Archiver role in your system, and that you have enough disk space for storing the LPR images.
    NOTE: The Archiver follows the Hit and Read image retention period set for the LPR Manager. If multiple LPR Manager roles are linked to the same Archiver, the LPR Manager with the longest image retention period wins. This means that the image data might be kept longer than necessary for some LPR Manager roles, but it does not affect the LPR metadata nor the LPR reports. No LPR data beyond the specified retention periods appear in reports.
  8. Click Advanced settings, and optimize the settings for storing LPR image data.

    The recommended values are:
    Delete oldest file when disks are full
    OFF (default setting for video is ON).
    Maximum length
    60 minutes (default value for video is 20 minutes).
    Maximum size
    100 MB (default value for video is 500 MB).
  9. Click OK > Apply.
  10. Click Apply.
  11. In the entity browser (left pane) of the Video task, make sure that the Media Router role is running.

  12. Click Media Router and configure the ports, redirectors, and network cards to make sure that the Archiver can deliver the LPR images to all client workstations on your system.
    If all your servers are on the same network, and all your servers have only one network card, the default settings should work without any change.
