The way the unit reacts to events depends on how it is programmed.
An event can cause either a trigger or an alarm. A trigger changes the way the unit works but
does not require a response from the user. An alarm also changes the way the unit works but,
in addition, usually activates several indicators and requires the user to acknowledge the
alarm situation.
The unit reacts to an event in any one of the following ways:

Background events
Triggers and alarms can change background tasks that a user may not notice. Unit responses
that are not visible to the user are, for example, a change in recording speed, the activation of
the output relay, and event logging. The unit can also be configured to record upon the
activation of an alarm input. A trigger may change the way the camera images are displayed on
the monitors without requiring intervention.
