About the Event Detection Ctrl Ext

The Event Detection Ctrl Ext provides a standard mechanism to enable or disable particular alarm events on specific cameras. This means you can enable or disable different events on a per-camera basis, based on some boolean logic (for example, a Schedule). The Event Detection Ctrl Extension has a single boolean property (shown in Figure 22) and is described below.

Enable Detection

This property has true and false options to enable and disable the associated event and a null option which prevents any input to the event from this extension.

You can use can use this property to enable or disable the video alarm event that it is associated with. For example, you can link a boolean writable control point to this property and use that property to change the Enable Detection status, as desired.

You can link any boolean logic from within NiagaraAX to this property; it does not have to be from a boolean writable point.

The Event Detection Ctrl Extension is available from the videoDriver palette.
