FAQ: notifications
Desktop notifications for alarms must be enabled by your system administrator in XProtect Management Client. Otherwise, you will not receive any.
Go to the Alarm Manager tab and look in the alarm list. If you do not see the alarm, it may have been filtered out. Try changing the filter settings.
If the alarm list is configured to show events instead of alarms, click the Setup button. In the Properties pane on your left-hand side, in the Data Source list, select Alarm and click Setup again.
A desktop notification stays on the screen for 15 seconds. If multiple alarms occur consecutively within a few seconds, you will still only see one desktop notification. When you click the desktop notification, the most recent alarm opens in the alarm window. To view the previous alarms, go to the alarm list.
