Chapter 13
Alarm and event setup
This chapter describes the alarm and event setup menu and provides more information
on the different types of alarms and connected responses. Alarms are all notifications
related to either physical alarm inputs on recorders and cameras or anything that does
not work as expected: device errors, network issues, and video loss.
Set up alarm inputs
The recorder can be configured to record when an alarm is triggered by an external
alarm device (for example, PIR detector, dry contacts…). A inputs are marked A for
analog and are physical inputs of the recorder. D inputs are marked as D for digital and
are physical inputs on the IP cameras.
To set up external alarms:
1. From the menu toolbar, click
Alarm & Event Setup
>
Alarm Input
.
2. Select the alarm input number of a camera, which corresponds to the connector on
the back panel of the recorder, and enter the name of the input, if required.
3. Select the alarm input type, NO (normally open) or NC (normally closed). Default is
NO.
