Events in Cisco VSM can use a soft trigger to perform an action (such as adjusting a camera's PTZ settings). The soft trigger is activated when Cisco VSM receives a URL from an external system, such as ICPAM.
For example, when a door is forced open, a Door Forced Open event is generated and a URL can be sent to Cisco VSM. Cisco VSM then executes actions based on that URL, such as panning the camera and creating a video archive. The process works as follows:
1. Create a event in Cisco VSM, and choose the Enable Soft Trigger option. A URL used to trigger the event is automatically generated and displayed.
2. In ICPAM, create a URL action using the Cisco VSM URL that was automatically generated when you created the VSM soft trigger.
3. In ICPAM, create an automation rule (global I/O rule) that triggers the URL action when a door forced open event occurs.
4. ICPAM sends the URL to Cisco VSM.
5. When Cisco VSM receives the URL, the camera pans and a video archive is created.
The following figure illustrates this example.
