Event Action Setup
Highlight the Alarm In Event Action , Motion Detector Event Action , or Video Loss Event
Action in the Event Action menu and press the button. The following Event Action setup
screens will appear.
NOTE:
Program event dwell times to expected event periods. Proper dwell time programming
will minimize excessive Event Log entries.
DWELL TIME refers to the length of time the DVR will record video and/or annunciate
external alarm outputs. The Dwell Time begins and video begins to be recorded at the time of
the initial event. Typical events are the alarm-in signal, a detected motion event or a video
signal interruption.

time is recommended. The proper use of
dwell times will assist in the operation of remote event search functions.
If the programmed dwell times are shorter than the total event time, multiple individual events
will be recorded on the hard disk drive and logged in the Event Log. If the dwell time is chosen
to closely match the total expected event length, the number of events listed in the Event Log
will be reduced.
What happens when the event is longer than the dwell time?
If an event is sixty seconds but has a programmed event dwell time of ten seconds, a total of six
(6) individual events will be listed in the Event Log. After the first event begins and the initial
ten seconds of dwell time expires, a new event (with an additional ten second dwell time) will
be triggered by the event. As a result the Event Log will show six entries that can be viewed
individually.
What happens if the event is shorter than the dwell time?
Let’s say an event lasts thirty seconds and the dwell time is programmed for sixty seconds. You
will get one event in the Event Log, lasting the dwell time limit of sixty seconds.
What happens if the event stops shortly after the dwell time?
Let’s say an event is expected to last twenty seconds and the event dwell time is programmed
for twenty seconds, and the event exceeds the twenty-second time expectation by only one
additional second. Then you will have two events in the event log, each with a twenty-second
dwell time.
Proper dwell time programming will minimize excessive Event Log entries and the necessity of
multiple event viewing.
