Alarm Message Latch The ALARM MESSAGE LATCH option determines how long
the ALARM and VIDLOSS (video loss) messages remain on
screen. It toggles as follows:
ON — ALARM messages remain on screen until you press
function to clear them. Pressing function removes all
video loss messages and messages for expired alarm
events. Messages for current alarm events remain on
screen.
NOTE: If video is not restored before the VIDLOSS mes-
sage is cleared, the monitor displays the last im-
age received until the display format changes or
video is restored.
OFF — Each message remains on screen until the ALARM
DURATION time expires (the default is 4 seconds) or the
corresponding alarm event clears.
The default ALARM MESSAGE LATCH setting is OFF.
Video Loss Alarm The VIDEO LOSS ALARM option controls the multiplexer
video loss detection feature. It toggles as follows:
ON — The multiplexer responds to camera video loss as
an alarm event and displays the message VIDLOSS in
place of the camera’s picture on both monitors. If ALARM
MESSAGE DISPLAY is set OFF, the message only displays
on the call monitor. The ALARM COUNTER counts a video
loss as an alarm for that camera input.
OFF — Camera video loss is not treated as an alarm event,
and a VIDLOSS message is not displayed on either moni-
tor. The ALARM COUNTER does not count the video loss
as an alarm. The only sign of video loss is that the moni-
tor displays the last image received from that camera un-
til you change the display format, when a blank window
with the camera number displays. Refer to Video Loss
Alarms for more details.
The default VIDEO LOSS ALARM setting is ON.
