About Video Driver alarms
All video surveillance systems that are built on the API from the Video Framework module (videoDriver.jar) support two kinds of alarming in NiagaraAX, as illustrated in Figure 8 Video Driver alarms.
NOTE: The ‟remoteVideo” feature allows licensed supervisor stations to view video from remote stations. To use this feature, the supervisor must be licensed for remoteVideo and the remote station must be available under the supervisor’s NiagaraNetwork.

- Video surveillance system alarms
These types of alarms are sent to NiagaraAX from the video surveillance system. For example, a video surveillance system that is configured to detect motion, may send the current status of the event to a NiagaraAX station when motion is detected. ‟Camera failure” and other types of specific video surveillance system parameters may also be sent as event status, depending on the capabilities of the system and the driver.
Figure 9 Video surveillance alarm (motion detected) routed to NiagaraAX alarm console shows an event that has been routed from a video surveillance system to a NiagaraAX alarm console. Alarms that are routed from the video surveillance system to NiagaraAX appear as ‟events” in the NiagaraAX environment.
NOTE: Video alarms are indicated in the NiagaraAX alarm console by the filmstrip with green arrow button icon (
). Only video alarms have this icon. You can also select and play video alarms from the alarm console by clicking the button at the bottom of the console.
See About Video Events for more details.

- NiagaraAX alarms
These types of alarms include alarms that are used by NiagaraAX (typically, outside of the video surveillance system) to initiate an event on the video surveillance system so that it can respond in some way. For example, a ‟door forced open” alarm delivered to a NiagaraAX alarm recipient may send an event to a surveillance system that can respond by using its pan, tilt, and zoom capabilities to point the camera toward specific ‟preset” door area and immediately begin recording.
