*1
Initial default setting when camera is not registered
*2
Initial default setting when camera is registered (Compression Format: JPEG, M-JPEG)
*3
Initial default setting when camera is registered (Compression Format: MPEG-4)
Note:
•
In the case of an MPEG-4 image, set a recording time of at least 10 seconds.
•
Refer to the following table as a guideline when setting the times in pre-event recording.
Duration
2s / 5s / 10s / 20s / 30s
*1*2*3
/ 1min /
2min / 3min / 5min / 10min / 15min
/ Manual / Continue
Specifies the time of post-event recording.
•
When [Manual] is selected, recording is performed only
while the alarm signal is being input. At that time, minimum
recording time is eight seconds.
•
Selecting [Continue] causes recording to continue until the
"Alarm [ALM]" button is clicked.
Recorder setup
Audio rec.
(Audio recording)
Off
*1*2*3
/ On
Specifies whether audio should be recorded with images.
•
Audio and images are recorded at the same time. Audio only
recording without image recording is not supported.
•
Audio recording can be selected only for a camera model
that supports audio recording.
Camera setup
SD memory rec.
(SD memory recording)
Off
*1*2*3
/ 0.1ips / 0.5ips / 1ips
Specifies whether images should be saved to an SD memory
card if the signal is lost during recording.
•
If the camera is a model that supports SD memory recording
and the recording format is [M-JPEG], you can specify a
recording rate. For information about SD memory recording,
refer to About SD memory recording (page 36).
•
Do not set SD memory recording rates on multiple network
disk recorders for the same camera.
•
Audio recording and SD memory recording cannot be done
at the same time.
If the SD memory recording rate for a camera is set to
anything except [Off], audio recording for that camera
channel is automatically set to [Off].
Important:
•
Recording at the set recording rate and for the set recording time may not be possible depending on the network environment or the size of
image data.
•
When a pre-event recording area has not been assigned to the HDD, the maximum pre-event recording time with audio on is 30 seconds.
•
We recommend setting the camera's refresh cycle to one second if the camera's compression format is MPEG-4. If the camera's refresh
cycle is too long, pre-event recording data may not be created.
•
Recording for the set Post-event recording time may not be possible depending on the timing of the event occurrence.
•
When "Audio" and "Audio rec." are set to [On], ensure that the audio mode of the camera is set to [On]. Also, set the cameras audio bit rate
to "32 kbps".
•
When the camera's audio bit rate is set again during operation, set the audio recording settings on the recorder to [Off] and then back to
[On] again.
•
Audio interruptions may occur because of the "Mic input interval" (intervals for audio reception) setting of the camera. Select the interval
setting of the camera according to the network environment.
•
Audio interruptions may occur because of the recording rate. To resolve this, change the recording rate according to the network
environment.
•
To record audio, set the camera's "Audio transmission/reception" to "Mic input" or "Interactive(full duplex)". Some models and versions of
cameras do not support "Interactive(full duplex)". For details refer to the operating instructions for the camera.
•
Audio is recorded regardless of whether single or multiple screen display is set.
