Camera setup
■ SD memory rec.
Determine whether or not save images on the SD mem-
ory card when the network communication is discon-
nected during emergency recording.
The following recording rates are available for "SD
memory rec.".
Off (default)/0.1ips/0.5ips/1ips
Refer to page 36 for further information about the SD
memory recording.
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".
• 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.
Important:
• If receiving a signal input that triggers an emergency
recording when the communication between the
recorder and the camera is not established, the SD
memory recording will not be performed (since the
camera cannot recognize the trigger of the emer-
gency recording).
• When selecting "On" for "Audio rec.", make sure
that the settings of the camera are configured to
transmit audio. Set also the audio bit rate of the
camera to "32kbps".
• When the audio bit rate of the camera is changed
during operation, set the "Audio rec." setting of the
recorder to "Off" once, and then set to "On" again.
• Audio may be interrupted depending on the audio
transmission interval setting of the camera. Change
the settings of the camera according to the network
environment.
• Audio may be interrupted depending on the record-
ing rate setting. Change the recording rate setting
according to the network environment.
• To record audio, select "Mic input" or "Interactive
(Full-duplex)" for the "Audio transmission/reception"
setting of the camera."Interactive(Full-duplex)" may
not be available depending on the model or version
of the camera. Refer to the operating instructions of
the camera in use for further information.
• Audio will be recorded regardless of the screen pat-
tern (1-screen, multi-screen).
[Measurement] button
It is possible to check if the set recording rate and
transmission rate are appropriate for the network in use
by clicking the [Measurement] button. When the record-
ing rate or the transmission rate is displayed in red, it
may be impossible to transmit live images or record
images at the current rate. It will take around 90 sec-
onds to check.
• When the result value is beyond the maximum net-
work speed of the recorder, the following may occur
due to the heavy network traffic:
• Some images to be recorded may not be done.
• Some live images to be displayed may not be
done.
• Some alarms to be issued may not be done.
• Operational response may become slow.
• The recorder may reboot.
• Even when the result value is below the network
speed (128 Mbps as indication), the above prob-
lems may occur depending on number of the con-
nected cameras and PCs.
Important:
• Network traffic changes every moment. In any cir-
cumstances, the result value should be less than the
maximum network speed of the recorder.
• In the process of the measurement, recording, play-
back, live image display and copying will stop.
