Global Alarm Settings
The Alarms tab allows the global settings for all alarms supported by the multiviewer to be
configured.
The alarms supported depend on the options licensed or fitted to the connected multiviewer and
the threshold ranges depend on the type of audio meter standard selected on the Audio System
tab.
The following settings affect all PiPs that use the corresponding alarm.
Frozen Picture Delay
Time in seconds (1-60) - the amount of a time of video source would need to remain static
before being declared frozen.
Level (1-30) - the percentage of motion allowed in picture before it is deemed to no longer be
static. (Normally used with noisy analog inputs)
Black Picture
Time in seconds (1-60) - the amount of time a video source would need to remain below the
black level threshold before being declared black.
Level (0-255) - the video level or threshold below which pixels are deemed to be black. Black
is set to 16 (default) and white is set to 235.
Percent (0-10) - the percentage of picture allowed above the black level threshold in a black
picture. The threshold back-off percentage control is provided so that a brief period of
blackness won't trigger the alarm.
