Schedules Item Settings Description 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]. *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) 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. 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.
