To receive Match and No match license plate events in Security Desk, you need to turn on hotlist matching so that the Sharp units can match license plates against active hotlists and permit lists.

Before you begin

The hotlist or permit list must be active and managed by an ALPR Manager so that the events are monitored.

What you should know

When hotlist matching is turned on, you can configure event-to-actions in Security Desk, based on Match events (license plate read by the Sharp was on a hostlist) and No match events (license plate read by the Sharp was not found on a specific hotlist).

Typically, No match events are used in access control scenarios. For example, you can associate a hotlist to a specific Sharp unit that is monitoring access to a parking lot or similar location. In this scenario, a Security Center event-to-action for a License plate hit grants the vehicle access (opens a gate, raises a barrier, and so on), and an event-to-action for a No match could trigger an alarm, or send an email to security personnel.


  1. From the Config Tool home page, click System > Roles.
  2. Select the ALPR Manager you want to configure, and then click the Properties tab.
  3. Turn the Matching option ON.
  4. (Optional) To generate “no match” events when a license plate is read by a Sharp and it is not part of a hotlist or permit list, turn the Generate “No match” events option to ON.
  5. Click Apply.
