3-6. Alarm
3-6-1. General
The events reported from individual cameras' digital inputs, digital outputs, and motion detection
can be accommodated in the NVR system's alarm settings. The NVR also comes with DI and
DO pins. These events will then be reported or commanding to trigger corresponding actions as
follows:
1. Reporting events via Email or system buzzer.
2. Triggering video snapshot and text message by the occurrences of events to an FTP/HTTP
site.
3. Triggering the camera(s) for its lens to move to a preset position.
4. Triggering the cameras' or the NVR's digital output.
5. Alerting the administrator with alarms indicators on the Alarm panel.
You can create up to 16 instances of alarm.
Hardware connections to DIs or DOs, e.g., window sensors, should be made separately. The
motion detection configuration is also made via a web console with individual cameras.
