Note:
When "MANUAL" is selected for "DURATION"
(recording duration), recording will be performed for
at least 8 seconds at an event occurrence as long as
the alarm is not canceled.
Important:
• Depending on the network traffic or environment,
images will not be recorded as configured (by setting
the pre-event recording rate and the recording dura-
tion).
• It is recommended to set the refresh interval of the
camera to 1 second or 4 seconds when selecting
"MPEG-4" for the image compression method. When
a longer refresh interval is set, images to be record-
ed by the pre-event recording may not be recorded.

CAM SETUP
Set the recording rate for the SD memory recording for
each channel.
The following recording rates are available for "SD
MEMORY REC".
OFF/0.1 ips/0.5 ips/1 ips
When "OFF" is selected, the SD memory recording will
not be performed for the respective channel.
Notes:
• The recording rate setting for "SD MEMORY REC" is
available only for cameras with the SD memory
recording function and their image compression
method is set to "M-JPEG".
• The recording rate for "SD MEMORY REC" should
be less than the recording rate set for "LIVE VIDEO".
When the camera in use is WJ-NT304, recording will
be performed at 0.2 ips even when "0.5 ips" or "1
ips" is selected for the recording rate for "SD MEMO-
RY REC".
• When setting the recording rate for "SD MEMORY
REC", make sure that "Use" is selected for the "SD
memory card" setting of the camera.
When "Use" is not selected or when no SD memory
card is mounted on the camera, error messages
may be displayed several times a day, and recording
may be interrupted for around 20 seconds each time
the error message is displayed.
This may also occur when the firmware of the cam-
era is older. In this case, upgrade the firmware of the
camera.
When the firmware version of the camera in use is
not the version listed below, upgrade the firmware.
