Note:
• Images from a camera channel for which the pre-
event recording area is created on the hard disk
drive will be recorded on the created pre-event
recording area. Refer to the "Format the pre-event
recording area" section on page 91 for information
on how to create the pre-event recording area.
• Refer to page 46 for the recording duration of the
pre-event recording without creating a pre-event
recording area as references.

Note:
• The recording rate setting for "SD memory rec." is
available only for cameras that support the SD
memory recording function and their image com-
pression method is set to "M-JPEG". Refer to page
36 for further information about the SD memory
recording.
• Do not set the recording rate of the SD memory
recording for the same camera with multiple record-
ers.
• It is impossible to simultaneously perform audio
recording and the SD memory recording.
• When the "SD memory rec." setting on the
"Emergency rec." page is set to other than "Off" for
a camera channel, the "Audio rec." setting on the
"Emergency rec." page for this camera channel will
be set to "Off" automatically.

tered
*2 The default setting when the camera is registered
(Compression method: JPEG, M-JPEG)
*3 The default setting when the camera is registered
(Compression method: MPEG-4)
Important:
• Depending on the network environment or the size
of images to be recorded, the recording rate and the
pre-event recording duration of the recorded data
may not be exactly same as the set recording rate
and recording duration for the pre-event recording.
• When no pre-event recording area is created on the
hard disk drive for a camera channel, the recording
duration of the pre-event recording with audio will
be 30 seconds.
• When "MPEG-4" is selected for the image compres-
sion method of the camera, it is recommended to
set the refresh interval of the camera to "1 second".
When a longer interval is set for the refresh rate of
the camera, it may fail to create pre-event recording
data.
