PLAY MODE: SEQUENCING DURING PLAYBACK
During the Play mode, the multi-screens and full-screens are sequenced according to the
sequence list and dwell times programmed in the menus. (Refer to the descriptions in the Live
mode section of the manual.)
CAUTION:
When sequencing the display during Playback, do not set the VCR's Play speed
such that the frequency at which any one camera is Played back off the tape is
slower than the frequency that the sequence list will switch through cameras in
the list.
Example:
If the VCR is set to 48 hour mode while Playing back a tape with 9 cameras recorded, then a field
for any one camera will generally not be sent from the VCR to the multiplexer more often that
every 5 seconds.
If the sequence dwell time is then set to 2 seconds, there is a very good
chance that the display will not be updated with a field from VCR for the current camera in the
sequence, before the sequencing switches to the next camera in the sequence list.
Recommendation:
Set the VCR to its 2hour speed when sequencing the displays during Playback.
NOTE:
Tapes being Played back may be from different sites or different setups, and may
have nothing to do with the current Live setup of the unit. Hence, the multi-screen
sequencing option will sequence through only the cameras that are not already on
the multi-screen. Any video loss or disabled cameras setup or detected in Live or
during recording will be ignored.

ALARMS
The SW-D7000U are equipped with one alarm input per camera input, each of which is normally
associated with its corresponding live video input. An active alarm input can result in an on-screen
indication on both Monitor-A and Monitor-B, a flashing front panel LED, an internal buzzer and
automatic modification of the record list to give the camera in alarm a higher update rate.
