To receive Match and No match license plate events in Security Desk, you need to turn on hotlist matching. Sharp units can then 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 enabled, you can configure event-to-actions in Security Desk, based on the following types of events:
- Match event
- A license plate read by the Sharp is on a hotlist.
- No match event
- A license plate read by the Sharp is 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 monitors access to a parking lot or similar location. In this scenario, a Security Center event-to-action for a License plate hit event grants the vehicle access, such as opening a gate or raises a barrier. In the same scenario, an event-to-action for a No match event could trigger an alarm or send an email to security personnel.
Procedure
- From the Config Tool homepage, click .
- Select the ALPR Manager that you want to configure, and then click the Properties tab.
- Turn on the Matching option.
- (Optional) To generate No match events when a Sharp unit reads a license plate that is not part of a hotlist or permit list, turn on the Generate “No match” events option.
- Click Apply.
