9 Handling events
Observer can record and display events of various types. These can be camera-related events like
video analytics events, archive access by a user, or camera failures, but also system-related events like
user logon and logoff.
Events are displayed in Event lists of the client and are stored in the central event database of the
server were they can also be queried. They have several properties that depend on the type of the
event.
Event priorities
All events also have an event priority that defines the relative importance of events. The default event
priority is 100. Informational events have a lower priority of 50, system and camera malfunction events
have a higher priority of 300. For events generated by video analytics triggers, you can specify
individual event priorities. Event lists can also be sorted according to priority.
User privileges for accessing and handling events
In the
User admin
under the
System administration
menu you can define for each user some basic
event handling privileges. For example whether user you can access events at all or what kinds of
system events are displayed at the users event list (see
5.2 Setting general user privileges
on page 45).
The number of events stored in the database can be defined in the server parameters (see
11.2 Setting
Observer server parameters
on page 110).
