When an intrusion alarm is triggered, the system uses the best camera returned by the camera selection algorithm to display the intrusion alarm. If no best camera can be found, all cameras assigned to the RSA zone are displayed.

What is an intrusion alarm?

An intrusion alarm is an alarm that is triggered when a new target enters an armed RSA zone. The alarm being triggered is the one that is configured for the Alarm on intrusion property of the RSA zone. If no intrusion alarm is configured for an RSA zone, the Default alarm on intrusion defined for the RSA Surveillance plugin is used.

NOTE: No intrusion alarm is triggered if an existing target moves into an armed RSA zone.

How does RSA Surveillance select which camera to display?

When an intrusion alarm is triggered, one of two behaviors occurs:

If the camera selection algorithm finds the best camera among all cameras in the system, only that camera is displayed for the alarm.
If no best camera can be found, all cameras assigned to the RSA zone are displayed.

The system follows the Video display option configured for the intrusion alarm. This means that if the alarm is configured for playback, only playback video is displayed. For more information, see Selecting video display options for alarms.

Limitations

Alarm display and target auto-tracking are two independent features. The camera selected to display the alarm when the alarm is triggered remains the same for the life of the alarm. If a best camera was found when the alarm was triggered, the system continues to display that camera, even after the target moves out of that camera's FoV. If no best camera was found when the alarm was triggered, the system does not switch to a better camera even after the target moves into the FoV of an eligible camera.
