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 Video Driver 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.

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 Discover button.

Refer to the NiagaraAX-3.x Drivers Guide for more information about using the Point Manager view.

The Events camera extension has the following properties:

Individual Events appear under the Event Camera Extension once they are “Added” to the Database pane from the Discovered pane. Types of Event points may differ, depending on the Video Driver type. The following events are typical Events:
- Camera Fail
