(Alarm recording) During alarm recording, pre-
alarm recording is performed at the picture grade
set for alarm recording. And for only the cameras
used for alarm recording, pre-alarm recording is
performed at the alarm recording rate.
iii) To perform with alarm recording:
Set the “Alarm Mode” to “Alarm Plus.”
Pre-alarm recording is performed at the picture
grade and the recording rate set for alarm
recording.
• Pre-alarm recording is executed with the recording
rate and the picture grade of the normal or alarm
recording set for that time period.
step6. Set the alarm recording time in “Post-Alarm
Duration.”
Manual: Continues alarm recording until the
ALARM IN terminal is not grounded.
step7. Set the recording camera for each sensor connected.
• Select “View” and display the overview screen to
check the settings of all the sensors.
• The multiple camera numbers can be set for one
sensor input.
step8. Set the trigger of alarm recording for each sensor
connected.
External & MD-A: Starts alarm recording when the
motion A is detected while the ALARM IN terminal
is grounded.
External & MD-B: Starts alarm recording when the
motion B is detected while the ALARM IN terminal
is grounded.
External: Starts alarm recording only when the
ALARM IN terminal is grounded.
External / MD-A: Starts alarm recording when the
ALARM IN terminal is grounded or the motion A is
detected.
External / MD-B: Starts alarm recording when the
ALARM IN terminal is grounded or the motion B is
detected.
MD-A: Starts alarm recording only when the motion
A is detected.
MD-B: Starts alarm recording only when the motion
B is detected.
• When setting the trigger to “MD-A,” “MD-B,” “External
/ MD-A,” “External / MD-B,” “External & MD-A,” or
“External & MD-B,” the motion detection function
becomes active immediately after exiting <Set
Recording Pattern A (Normal/Timer) to D (Timer)>.
To stop the input of alarm signals, set the “Alarm Input”
setting in the <Recording> menu to “Off.”
step9. Set the PTZ camera preset.
• When the alarm input set on step 8 is input, the
camera corresponding to the sensor number
adjusts its angle to the preset point set on this
step.
– – –: Does not adjust the camera angle.
• Select “View” and display the overview screen to
check all the settings set on steps 8 and 9.
• When the trigger is set to “MD-A” or “MD-B,” PTZ
camera preset cannot be activated. In this case, the
PTZ camera preset does not function even when the
setting is set to other than “– – –.”
Alarm recording
• When alarm recording or emergency recording is input
during timer recording, the end time of the timer
recording is extended until the alarm recording or the
emergency recording is completed.
• When the alarm recording trigger is set to “External /
MD-A” or “External / MD-B,” the priority is given to
the latest alarm input.
• When the alarm recording trigger is set to “External /
MD-A” or “External / MD-B,” and the alarm recording
time is set to “Manual,” the alarm recording stops 2
seconds after the input of motion detection even if
the ALARM IN terminal is being grounded. (When the
alarm recording time for this recording according to
the motion detection is set to “Manual,” the actual
recording time is 2 seconds.)
• When power failure occurs during alarm recording or
emergency recording, the alarm recording or
emergency recording is cancelled after returning from
the power failure.
• When alarms are input for multiple sensors at the
same time, all the alarms may not be registered to
the alarm list.
Frame recording and field recording
• In NTSC signal system, one picture is consist of two
screens, odd and even. The unit records only the
screen of odd in case of field recording. In case of
frame recording, both of the screens (odd and even)
are recorded.
• Frame recording is suitable for storing the data in the
high picture quality, however, the data capacity is twice
as large as that of the field recording of the same
picture grade (1 frame = 2 fields). The picture may be
looked like vibrating because one picture is consisted
by two screens.
Alarm Input
This item is used to stop the alarm input manually. When
setting “Alarm Input” to “Off,” the alarm input is stopped for
5 minutes. When setting the <Recording> menu while the
alarm recording occurs continuously, stop the alarm input
first to stop recording. “Alarm Input” function is available
for ALARM IN terminal on the rear panel, motion detection,
emergency recording, and communication port. To cancel
the prohibition of alarm input manually, set it to “On” or exit
the <Recording> menu. It is cancelled automatically after
5 minutes.
