Event Linking
The Event Linking Setup screen is where you connect different types of events such as an input trigger
to a desired action, for example, recording video or triggering an alarm.
An Event Type occurs on a predetermined Event Source which triggers an Action Type on a
predetermined Action Target . Events are stored in a database for you to quickly find.
The reason for linking an event to an action is to create a logical relationship between your physical
security devices to improve your ability to quickly search and find them when an event occurs. Event
linking helps to narrow the information you are looking for. As an example, let’s say you want to find
video every time a door opened in a busy lobby. If a camera that is pointed at a door and is set to
record upon motion you could simply search the camera for motion video. However, the problem is that
people standing or passing through the lobby also set off motion recording and you can’t distinguish it
from the door opening. A solution for distinguishing between when the door opens and people pass
through the lobby is to connect a door sensor to an input trigger and link it to video recording. Now you
can go to the event searching screen and select the event and only find video associated with the
event.
