Emergency Recording Setup
This item is used to set the emergency recording settings.
When the EMERGENCY terminal is grounded by the alarm
sensor while both of the MAIN switch on the rear panel
and the POWER button on the front panel are turned ON,
emergency recording starts automatically overriding all the
other settings even during timer recording or the unit is in
stop mode.
Emergency recording is not performed while the MAIN
switch or POWER button is turned OFF or while timer
recording stand-by mode.
The setting of the menu cannot be changed
during normal recording or alarm recording. To change
setting during recording, stop recording in case of
normal recording. In case of alarm recording, when the
“Alarm Input” in the menu is set to “Off,”
the alarm input is not accepted for 5 minutes. When you
stop recording during this time, the setting change of the
menu is available.

Emergency recording
1) The picture grade is “L6-30KB” and the recording rate
is set to the value obtained by dividing the maximum
emergency recording rate by the number of specified
cameras.
When the LPA area is set in the main device, the
emergency recording data is stored in the LPA area
and is automatically locked in 512 MB unit including the
emergency recording data in order to prevent overwriting
the data.
In LPA area, the data is always recorded at the rate set for
alarm recording regardless of an input of the emergency
signal. Therefore, when the emergency recording is
started from the mid-part of the data block, the data
recorded before the ground of the EMERGENCY terminal
is stored in the locked area along with the emergency
recording.
When you set the long pre-alarm recording time without
setting the LPA area, long pre-alarm recording is carried
out using the internal memory for pre-alarm recording, so
long pre-alarm recording is performed for the short time
period regardless of the setting.
When emergency recording is carried out using the LPA
area, data is not stored chronologically and alarms are
listed out of sequence. Be careful when searching for the
desired picture.
When power failure occurs during emergency recording,
the emergency recording is cancelled after returning from
the power failure.
When emergency recording is carried out during timer
recording, the end time of the timer recording is extended
until the emergency recording is completed. The timer
recording is finished after completing the emergency
recording.
2) Cameras to be used
Cameras which are set in
are used.
3) During emergency recording:
• “E-REC” is displayed on the screen in red.
• The camera number buttons and camera number dis-
play on the screen which are used for emergency re-
cording flash.
4) Emergency recording is registered in the alarm list and
displayed in magenta.
