Setting up the Archiver role for LPR

You must link an Archiver to the LPR Manager to store the LPR images that are associated with the reads and hits.

What you should know

If you need to manage both LPR and video data, we recommend that you create separate Archiver roles, each handling only one function.

Each Archiver role must store video on a separate drive or partition from other Archiver roles. 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.

To create an Archiver role for LPR:

  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.
    • Server: Click to hide description
      This is only shown 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. 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: Click to hide description
      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.
    • Database: Click to hide description
      Name of the database instance (default=Archiver). We suggest using LPR_Archiver to differentiate it from video archive databases.
  4. On the Basic information page, set the following fields, and then click Next.
    • Entity name: Click to hide description
      Name of the Archiver role (default=Archiver).

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

    • Entity description: Click to hide description
      Role description. If this Archiver role is shared by many LPR Manager roles, list them here.
    • Partition: Click to hide description
      This is only shown 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: Ensure 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. For more information on the storage requirements for LPR images, refer to the Security Center Release Notes.
    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 has precedence. 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: Click to hide description
      OFF (default setting for video is ON).
    • Maximum length: Click to hide description
      60 minutes (default value for video is 20 minutes).
    • Maximum size: Click to hide description
      100 MB (default value for video is 500 MB).
  9. Click OK > Apply .
  10. In the entity browser (left pane) of the Video task, make sure that the Media Router role is running.
  11. 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.
