Alarm definitions for LPR

Except for defining Triggering events, the settings for Alarm definitions are the same for LPR as for the remaining part of the system.

To define triggering events related to LPR, select the event message to use when the alarm is triggered:

  1. In the Triggering event field, in the top dropdown list, decide what type of event to use for the alarm. The list offers Match lists and LPR server events (see Match lists).
  2. In the second dropdown list, select the specific event message to use. If you selected Match lists in the dropdown above, select a match list. If you selected LPR server, select the relevant LPR server event message:
    • LPR camera connection lost
    • LPR camera running
    • LPR server not responding
    • LPR server responding

For information about the remaining alarm definition settings, see Alarm Definitions.
