Video loss alarm
If the loss of a video signal causes an alarm:
Monitor A or B can be set up to show the video loss signal.
• Monitor A switches to multiscreen view. The lost camera signal is displayed
as a black cameo with the video loss message. The border around the
camera with the video loss is red. An alarm status message is displayed.
• Monitor B: Sequenced display of cameras that do not have video loss.
• The alarm beeper sounds.
• The video loss and the indicators flash.
Acknowledging a video loss alarm
1. Press the acknowledge key to acknowledge a video loss alarm.
> The beeper is silent.
> The video loss and indicators are no longer lit.
> The alarm status message disappears.
> The last-used view mode is restored.
If the camera with video loss is visible, the black cameo and the video loss
message continue to be displayed as long as there is no video present.
If an alarm is not acknowledged, the beeper switches off after the dwell time but
the alarm still needs to be acknowledged.
If auto-acknowledge is enabled, the beeper, and the video loss and
indicators switch off after the dwell time.
Multiple alarms
Monitor A switches to multiscreen view if more than one alarm occurs. The
latest alarm status message is always shown. Pressing the acknowledge key
deactivates all alarms.
