License plate styles and aliases

License plate styles and aliases help you standardize and simplify how the system understands and interprets license plate data.

  • License plate styles define how plate numbers are displayed or grouped based on region, format, or use case. Applying consistent license plate styles helps improve the readability, search accuracy, and system consistency, especially when you work across different regions or formats.

  • Aliases enable you to assign a readable name to a license plate. Instead of tracking a number like ABC123, you can label it as Maintenance Van or Visitor – Jane Doe, making it easier to understand and manage entries.

These tools make it easier for you to search, identify, and respond to relevant vehicles in the system.

You can group license plate styles into aliases. See Aliases.

Aliases

A license plate style alias (alias) is a group of license plate styles. You can group license plate styles into an alias by creating the alias and assigning the alias to the license plate styles of your choice.

You don't need to use aliases, but they could be useful for a number of reasons:

  • Aliases help you categorize license plate styles according to your license plate recognition needs. See Example scenario.

  • License plate styles have long and complex names that might be difficult to work with. Using aliases, you can give license plate styles a more descriptive group name.

  • You can add aliases to match lists. See Add match list items.

  • The XProtect Smart Client operator can add aliases to match lists.

Find license plate styles used in your system

Every country module contains license plate styles. When you enable a country module, all the license plate styles that belong to that country module are also enabled.

To see a list of all license plate styles enabled in your system:

  1. Select Site Navigation > Servers > License plate style aliases > Assign aliases.

  2. In the License plate style column, see a list of all license plate styles enabled in your system.

Match lists support registration numbers, aliases and vehicle properties, but not individual license plate styles. If you want to include a specific license plate style in a match list, first create an alias for it. Then, add that alias to the list. See Group license plate styles into aliases. See Add match list items.

Add, edit, delete aliases

  1. Select Site Navigation > Servers > License plate style aliases > Configure aliases.

  2. Select:

    • Add to create an alias and specify an alias name

    • Edit to rename an alias

    • Delete to remove an alias

Group license plate styles into aliases

To group multiple license plate styles into an alias, you need to assign an alias to the license plate styles.

  1. Select Site Navigation > Servers > License plate style aliases > Assign aliases.

  2. For each license plate style that you want to assign an alias to:

    1. Select the dropdown in the Alias column.

    2. Select the alias of your choice.

Example scenario

In this example, let's create aliases and assign them to license plate styles in the Denmark country module.

To follow along, open the Management Client and enable the Denmark country module.

For our license plate recognition needs, we decide to categorize license plate styles in the Denmark country module into the following groups:

  • Commercial

  • Motorcycle

  • Private

  • Standard

With the Denmark country module already enabled, let's first create the aliases, and then assign them to license plate styles.

Create aliases

  1. Select Site Navigation > Servers > License plate style aliases > Configure aliases.

  2. Select Add to create an alias.

    Let's create the four aliases:

    • DK_COMMERCIAL
    • DK_MOTORCYCLE
    • DK_PRIVATE
    • DK_STANDARD

Next, let's group license plate styles into aliases by assigning the new aliases to the license plate styles.

Assign the aliases to license plate styles

  1. Select Site Navigation > Servers > License plate style aliases > Assign aliases.

  2. For each license plate style that you want to assign an alias to, select the dropdown in the Alias column and select the alias of your choice.

    We assign aliases to license plate styles in the Denmark country module as follows:

License plate style

Alias

  • DK_commercial_since_1976

  • DK_commercial_since_2008

  • DK_commercial_since_2009

  • DK_commercial_since_2009_twoline

DK_COMMERCIAL

  • DK_motorcycle_since_1976

DK_MOTORCYCLE

  • DK_private_transport_since_2009

  • DK_private_transport_since_2009_euroband

  • DK_private_transport_since_2009_twoline

  • DK_private_transport_since_2009_twoline_euroband

DK_PRIVATE

  • DK_standard_since_1976

  • DK_standard_since_2009

  • DK_standard_since_2009_euroband

  • DK_standard_since_2009_twoline

  • DK_standard_since_2012_holograph

DK_STANDARD

Note that we assigned the DK_MOTORCYCLE alias to only one license plate style. We did that because we want to use this specific license plate style on a match list, and match lists support aliases but not individual license plate styles.

In this example, we created aliases and assigned them to license plate styles. A possible next step is to add the aliases to match lists. That way, we can associate different groups of license plate styles with different LPR events. For example, we can open a gate to a vehicle only if the license plate style of the vehicle is part of the DK_COMMERCIAL alias. See Match lists.
