Management Client elements
With user-defined events, you can use data received from a third-party access control system as
events in the system. The events can later trigger actions. This way, you can, for example, begin
recording video from relevant cameras when somebody enters a building.
You can also use user-defined events for manually triggering events while viewing live video in
XProtect Smart Client or automatically if you use them in rules. For example, when user-defined event
37 occurs, PTZ camera 224 should stop patrolling and go to preset position 18.
Through roles, you define which of your users are able to trigger the user-defined events. You can use
user-defined events in two ways and at the same time if required:
Events
Description
For providing the ability to
manually trigger events in
XProtect Smart Client
In this case, user-defined events make it possible for end users to
manually trigger events while viewing live video in XProtect Smart
Client. When a user-defined event occurs because an XProtect
Smart Client user triggers it manually, a rule can trigger that one or
more actions should take place on the system.
For providing the ability to
trigger events through API
In this case, you can trigger user-defined events outside the
surveillance system. Using user-defined events this way requires
that a separate API (Application Program Interface. A set of
building blocks for creating or customizing software applications) is
used when triggering the user-defined event. Authentication
through Active Directory is required for using user-defined events
this way. This ensures that even if the user-defined events can be
triggered from outside the surveillance system, only authorized
users are to do it.
Also, user-defined events can via API be associated with meta-
data, defining certain devices or device groups. This is highly
usable when using user-defined events to trigger rules: you avoid
having a rule for each device, basically doing the same thing.
Example: A company uses access control, having 35 entrances,
each with an access control device. When an access control device
is activated, a user-defined event is triggered in the system. This
user-defined event is used in a rule to start recording on a camera
associated with the activated access control device. It is defined in
the meta-data which camera is associated with what rule. This way
the company does not need to have 35 user-defined events and 35
rules triggered by the user-defined events. A single user-defined
event and a single rule are enough.
When you use user-defined events this way, you may not always
want them to be available for manual triggering in XProtect Smart
Client. You can use roles to define which user-defined events
should be visible in XProtect Smart Client.
No matter how you want to use user-defined events, you must add each user-defined event through
the Management Client.
If you rename a user-defined event, already connected XProtect Smart Client users must log out and
log in again before the name change is visible.
Also note that if you delete a user-defined event, this affects any rules in which the user-defined event
is in use. Also, a deleted user-defined event only disappears from XProtect Smart Client when the
XProtect Smart Client users log out.
