Event Linking
The Event Linking page allows you to connect different types of events, such as the activation of an input trigger, to an
action, such as recording video or triggering an alarm. Event linking provides quicker searches for specific event types. For
example, you might normally search for motion video captured on a camera pointed toward a door; however, if the door
has a sensor, you could improve your search by looking for video recorded whenever the door opened by linking that
event with video recording.
You can see how it works by looking at the lists from left to right below the main Event List, as shown in the figure above.
When the specified Event Type (2) occurs on an associated Event Source (3), Action Type (4) is triggered on an Action
Target (5). These events are then stored in a database (if Log is selected in the Event List) to provide easy search
capabilities. To create a new event, complete the following steps:
1. Click the New button to add the event to the Event List.
2. Select the Event Type.
3. Select the Event Source. (If Soft trigger, Time Trigger, or Source Group is selected, you can create or edit the
event source using the buttons that appear immediately below the selection box.)
4. Select the Action Type.
5. Select the Action Target.
NOTE: See the charts on the following pages for information about available Event Types, Event Sources, Action Types,
and Action Targets.
6. Pre Trigger allows you to store buffered data that was captured up to 100 seconds before the event occurred.
This feature can be used only with certain Event Types. Very large Pre Trigger can negative impact system
performance.
7. Post Trigger continues the Action Type for up to 100 seconds of video after the event concludes.
8. Click Apply to save all changes to the selected event.
9. The Log Settings field determines how long the event will be stored in the Event database, from zero to 365
days.
