Event Linking
The "Event Linking" page allows you to connect different types of events, such as the activation of an input trig-
ger, 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 fig-
ure above.
When the specified "Event Type" w occurs on an associated "Event Source" e, "Action Type" r is triggered
on an "Action Target" t. 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:
Click the [New] button to add the event to the q
"Event List".
Select the "Event Type". w
Select the "Event Source". e
Select the "Action Type". r
Select the "Action Target". t
Note:
See the charts on the following pages for informa-•
tion about available Event Types, Event Sources,
Action Types, and Action Targets.
" y 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.
"Post Trigger" continues the Action Type for up to u
100 seconds of video after the event concludes.
Click the [Apply] button to save all changes to the i
selected event.
The "Log Settings" field determines how long the o
event will be stored in the Event database, from
zero to 365 days.
