Full-screen monitoring
: When an alarm is triggered, the monitor (VGA or HDMI)
displays an image in live view mode. For alarms that are triggered simultaneously,
images display one at a time every 10 seconds (default dwell time). You can set a
different dwell time using the “Dwell Time” setting under the Display
Settings>Layout window. When the alarm stops, cycling of the images stops and
you return to live view mode. This alarm option must be selected for each channel
where it is required.

Set up alarm outputs
You can connect the recorder to an alarm system, such as a siren or intrusion system,
which is then activated when an alarm is triggered. You can select how long the alarm
signal remains active as well as schedule when alarm outputs can be triggered. “A”
outputs are marked A for analog and are physical outputs of the recorder.
“D” outputs
are marked as D for digital and are physical outputs on the IP cameras.
To set up an alarm output:
1. From the menu toolbar, click
Alarm & Event Setup
>
Alarm Output
.
2. Select the alarm output.
3.
Select a timeout option between 5 and 600 seconds or select “Manually Clear”.
The timeout setting lets you define how long an alarm signal remains active after the
alarm has ended. If you select
Manually Clear
, the alarm signal remains active until
it is manually acknowledged by pressing the alarm button on the front panel (see
“Manual trigger” on page 106).
4. Select the recording schedules for the alarm output.
