2. Set the frame or field recording, maximum recording
step
rate per camera, and picture grade for alarm
recording.
Easy: Sets the frame or field recording, maximum
recording rate per camera, and picture grade for
alarm recording to the same settings for all the
camera numbers. When the recording rate is set
to "– – –" for all the camera numbers, this disables
alarm recording. Set the desired settings and then
select "Execute."
• The preview screen appears automatically when
the easy setting is executed.
Manual: Sets the frame or field recording,
maximum recording rate, and picture grade for
alarm recording individually for each camera
number. When setting "– – –" for the recording
rate, alarm recording is disabled for that camera
number.
• Select "View" and display the preview screen to
check the settings you have set.
The recording rate set for normal and alarm recordings
are the maximum number of frames. The number may
decrease depending on the number of cameras used for
recording.
The field recording and frame recording can be mixed.
However, when the total number of fields and frames
becomes nearly 120, the recording may not follow the
setting. The priority of the recording rate setting is, frame
recording > field recording > large recording rate > small
recording rate > small camera number > large camera
number.
Make sure to check the settings in the preview screen
after making the recording settings.
When the picture is recorded at the maximum recording
rate, a picture from the camera that is not currently used
for recording cannot be checked through communication.
When setting the frame recording, the recording rate
display in the preview screen turns green.
The recording rate display turns red when the total value
exceeds 120 pps.

Alarm: Starts alarm recording when the motion is
detected.
Normal: Starts normal recording when the motion
is detected. The recording is executed at the
picture grade and the recording rate set for normal
recording. The recording is not registered in the
alarm list.
Data is recorded in normal recording area when
the main device is partitioned.
Set alarm trigger on step 8 to "MD-A," "MD-B,"
"External / MD-A," or "External / MD-B."
In case of recording pattern A, you can start
normal recording by pressing the REC/REC STOP
button while the unit does not perform motion
detection recording.
In case of timer operation, normal recording is not
performed and the unit turns to stand-by mode for
motion detection. Recording is performed only by
the camera which detects motion.
For normal recording due to motion detection, <Alarm
Camera Setting> is not used and recording is performed
only by the camera of which the motion is detected.
For alarm recording due to ground of rear terminal,
recording is performed by the cameras set in <Alarm
Camera Setting>.
When motion detection recording is set to "Normal,"
<Alarm Camera Setting> cannot be set. To change
<Alarm Camera Setting>, switch the motion detection
recording to "Alarm" once.
When you set the alarm recording trigger to "External
& MD," normal recording due to motion detection is
performed only during the rear terminal is grounded.

Alarm CH: When alarm signal is input, performs
alarm recording only by the cameras set for
alarm recording. When there is an input of alarm
signals from multiple sensors, alarm recording
is performed by all the cameras to which alarm
signals are input.
When alarm recording starts during normal
recording, normal recording pauses while alarm
recording is performed.
Alarm Plus: When an alarm signal is input during
normal recording, performs alarm recording by
the camera and the recording rate set for alarm
recording while all the other cameras perform
recording at the normal recording rate. The
available recording rate for alarm and normal
recordings is up to 120 pps in total.
When you have set alarm recording mode to Alarm Plus
and then change the alarm recording rate to the value
exceeding the available rate, alarm mode changes to
Alarm CH automatically.
