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…). They are the physical inputs 
on the cameras and recorder. 
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. 
4.  Select the Enable Alarm Input checkbox and click Actions   to set up the rules 
for the cameras to be triggered, their alarm schedules, method of alarm notification 
and PTZ linking function. 
5.  Select the cameras to be triggered when an external alarm is detected.
