SW-D8000U, 16CH. COLOR VIDEO MULTIPLEXER
Example:
The default for associated cameras for camera #6 will be 5, 7 and 8, while the default for associated
cameras for camera #1 will be 16, 2, 3. The three automatic custom alarm screens are as follows,
depending on the number of active alarms:
Displays for more than 3 simultaneous alarms:
If more than 3 alarms are active at the same time, the SW-D8000U will automatically select a
display format which is able to show all the cameras in alarm. Associated cameras will not be
selected for display, and alarms will not be frozen. This will usually be a 9-way display, unless more
than 9 cameras are in alarm at the same time. As each new alarm is received, the unit will
automatically adjust the display.
Freezing Alarms on Monitor-A in Live Mode
The programmer can choose to have the camera in alarm frozen at the instant of the alarm. Use
the YES/NO selection under FRZ in the ALARM ACTION section of the ALARMS sub-menu to
select this option. The factory default for all alarm inputs is that the camera-in-alarm will be frozen
when an alarm input is received.
NOTE: If additional alarms are received while some cameras are already frozen, then all frozen
cameras will be unfrozen and re-frozen at the instant that the new alarm input was received.
The associated cameras are not frozen at the instant of alarm. This allows the programmer to
freeze the instant of alarm and still continue to track ongoing activity on the same screen.
Application Note:
If the programmer programs one of the associated cameras to the same camera number as the
camera in alarm, then this feature can be used to have a frozen image of the camera in alarm as
well as a Live image of that alarm camera on Monitor-A at the same time. This is not needed if
Monitor-B is installed.
A customized alarm display will be selected automatically by the multiplexer, depending on the
number of simultaneous alarm inputs, to show all cameras in alarm, plus associated cameras. The
custom screens are automatic for up to 3 simultaneous alarms.
Top left quadrant is the
camera in alarm and the
remaining 3 quadrants are
associated cameras
NOTE: The custom alarm screens on Monitor-A will be displayed only while an alarm is active.
Once an alarm times out or is cleared, the display will automatically revert to the screen
displayed before the alarm. It is very important to select the best alarm latching mode for
alarm displays.
MON-B Full-Screen during alarms:
During alarms, Monitor-B will automatically switch to a full-screen display of the camera in alarm. If
multiple alarms are active, Monitor-B will automatically sequence between the alarm cameras at a
fixed 1 second dwell. This dwell is not programmable. Monitor-B cannot freeze images.
NOTE: The Monitor-B screen will not revert to its original fixed display after the alarm is cleared. It
will continue to display the last alarm camera.
