Alarm Terminology

The following table explains the most pertinent terminology that is used when dealing with alarms. It is important to stick to this, as it will vastly reduce the chances of miscommunication.

Alarm Terminology	Description
Source	Represents the source or origin of the alarm. Possible sources are: Computers or NVRs Cameras Digital inputs Other hardware sources This value can contain a unique identifier that can be interpreted by the G-SIM system and then linked to a G-SIM component. In the case where the source is not a G-SIM component, this value represents a text description of the source. For instance, for camera failures, the source might contain the unique identifier of the camera or it might contain a text description containing a site reference and camera name in the format: Site - Camera
Location	Represents a text description of the physical location of the alarm source. It should refer to a location within a site.
Site	Represents the site the alarm originates from. A site is basically a grouping of locations and cameras which has been created by the G-SIM administrator. For some installations it is best to group physically (those close together), while in others logically (those which do the same thing, for example).
Camera	Represents the default camera associated with the alarm. Associating a camera with an alarm has two meanings: With camera failures, it represents the camera that failed. With all other events, it represents a camera that can be used to monitor the event.

As you can see, the terminology cements the concepts, and makes clear communication possible.
