Step
11
Select the trigger for starting alarm recording for
each connected sensor.
[EXT&MD-A]: Alarm recording starts when Motion
A is detected while the ALARM IN terminal is being
grounded.
[EXT&MD-B]: Alarm recording starts when Motion
B is detected while the ALARM IN terminal is being
grounded.
[EXT]: Alarm recording starts only when the ALARM
IN terminal is grounded.
[EXTorMD-A]: Alarm recording starts when the
ALARM IN terminal is grounded or Motion A is
detected.
[EXTorMD-B]: Alarm recording starts when the
ALARM IN terminal is grounded or Motion B is
detected.
[MD-A]: Alarm recording starts only when Motion A
is detected.
[MD-B]: Alarm recording starts only when Motion B
is detected.
Notice
When the trigger for starting alarm recording is other
than [EXT] or [EXT&MD], the motion detection function
activates immediately after you exit the <Alarm input/
output> screen.
To prohibit alarm signal input, set [Alarm input] on the
<Recording settings> screen to [Off]. (

Select the PTZ camera preset position for the
sensors for which the trigger is set to [EXT] in
step 11.
The cameras selected by [CAM] are moved to the
preset position selected by [P.set]. (The cameras do
not move when the trigger is set to other than [EXT].)
For preset position registration, see
pages 45

Supplementary explanations on recording settings
Alarm recording
When alarm recording or emergency recording is
performed during timer recording, the end time of the
timer recording is put off till the completion of the alarm
recording or the emergency recording.
When the alarm recording time is set to [Manual],
the recording time of motion detection recording is 5
seconds.
When a power failure occurs during alarm recording
or emergency recording, the alarm recording or the
emergency recording resumes after the recovery
from the power failure. The cumulative recording time
before the power failure is reset and it starts from the
beginning again.
When alarm signals are input to multiple sensors at
the same time, the recorder may not register all the
alarm events to the alarm list.
Frame recording
When the picture size is set to [4CIF] or [CIF], images
are recorded frame by frame. When you play back
recorded images having rapid motion, they may
appear shaking. When such shaking images are
annoying, see "Display a playback image in eld" (
page 112).
Caution in changing recording operations
When the picture size or recording rate changes due
to the change of recording operation (for example,
from normal recording to alarm recording, from normal
recording to emergency recording, switching the
timer operation), the recording may be interrupted
temporarily (for approximately one second). The
interruption time becomes longer as the load of the
recorder increases.
In the case that there is a large difference between
the picture qualities for normal recording and alarm
recording, the recorder may take time to achieve the
designated picture quality when the recording mode
changes from normal recording to alarm recording or
from alarm recording to normal recording.
