Start
Depending on the camera model or other hardware used, the following events can be used as triggers for an alarm scenario:
- Tampering: The camera angle is changed or the camera lens is covered.
- Video signal lost: The connection between the analog camera and the video server is cut.
- Motion detection: Significant motion has been detected in a defined area of the camera image.
- Digital I/O: An incoming digital signal triggers an alarm.
- VoIP events like starting or stopping a VoIP session
- Triggers from external interfaces like (access control systems, alarm systems)
- Click Edit to select the events that trigger the alarm. The hardware and event are displayed. You can select multiple objects.
The trigger must be created or activated before configuring the alarm scenario. One exception to this are buttons, which can be defined later in the buttons control (see Buttons). A starting event can be, for example, the receipt of a TCP signal from a camera when it detects motion. This is implemented via the
network I/O.
- Click Expert mode to specify the settings.
Expert mode
Expert mode can be used to create complex alarm scenarios. The alarm is triggered by different conditions that are logically linked (AND / OR conditions).
- Click Edit and select the conditions at the (digital) inputs that must be fulfilled to trigger an alarm.
- Set the period (in seconds) within which at least one of the following events from each group occurs.
- To add the events to the condition, click Edit and select the relevant objects.
