About Video Events
Events 
are like NiagaraAX points and are associated with video surveillance system alarms. Some video camera devices support importing
video surveillance system events and some do not. Video camera drivers that support events include an events component under
the camera device. The default view of the event device extension is the Point Manager view, which may be used to Add or
Discover video events (similar to NiagaraAX Point Discovery).

Event-enabled video drivers typically support the following types of events:
- Camera Fail
This event indicates that the camera is in a fault state.
- Motion Detected
This event indicates the motion detection status when the video surveillance system detects motion.
NOTE: Some video drivers (for example, Dedicated Micros Video driver) automatically populate the Discovered pane when the Point Manager view is displayed. If no events appear in the view - use the button.
Refer to the NiagaraAX-3.x Drivers Guide for more information about using the Point Manager view.
