The tape is not compatible with the decoding format selected by the programmer.
In the event that the tape was actually recorded on either a
SW-D8000U,
compatible
multiplexer or an alternate multiplexer, but is not correctly decoded, first check to see that the
correct
PLAYBACK FORMAT
has been selected in the menus.
To view tapes which were not decoded:
With the VCR Playing back a tape, press
FUNCTION
(
F
) then
PLAY
to view the undecoded
input. It should be clear from the undecoded Playback video if the video is multiplexed or not,
as several camera images will be overlaid on each other.

ALARM HISTORY
An alarm history is kept in a cyclic buffer. History data, including the camera number and time
and date is kept in memory for up to 100 events. The most recent 100 alarm events can be
viewed on-screen in this menu.
A table will appear, allowing you to browse forward and backwards among the last 100 alarmed
events. Each event relates the time of occurrence with an alarm-input number. The RS-232
remote control capability allows an operator to upload the alarm history to a PC or a similar
controlling device.

NORMAL RECORD SPEED
Unless VEXT (VCR sync pulse, installer programmed) is used, it is important that the
SW-
D8000U
be programmed with the same record speeds as those to which the VCR has been set
for
NORMAL
and
ALARM
recording.
Time-lapse VCRs are usually capable of dual speed operation, allowing two different speeds of
recording during
NORMAL
operation and
ALARM
situations. The
ALARM
recording speed is
usually the faster speed, and normally the fastest that the recorder will go, which is the 2 HR
speed setting for NTSC. Normal time-lapse recording is typically set to a slower speed, such as
12 hour to 960 hour, resulting in a tape saving while no alarm events are occurring. If the VCR
switch input (VEXT) is not active, then the recording speeds in the
SW-D8000U
menus must
match those set in the VCR. The factory default settings are 2 hour.
