[Normal recording settings]

step1. Follow the steps 1 and 2 on page 91 to set the recording camera, frame or field recording, recording rate, and picture grade for normal recording.

After executing the camera check, the recording setting is

made only for the camera numbers with the video signal input when using auto or easy setting.

<Estimated Recording Time>

The continuous recordable time depending on the recording rate and the recording picture grade of nor- mal recording is displayed as <Estimated Recording Time> on the bottom of the preview screen for normal recording.

When the main device is partitioned, <Estimated Re- cording Time> shows the estimated recordable time for normal recording.

[Alarm recording settings]

step2. Set the frame or field recording, maximum recording rate per camera, and picture grade for alarm recording.

Easy: Sets the frame or field recording, maximum recording rate per camera, and picture grade for alarm recording to the same settings for all the camera numbers. When the recording rate is set to “– – –” for all the camera numbers, this disables alarm recording. Set the desired settings and then select “Execute.”

• The preview screen appears automatically when the easy setting is executed.

Manual: Sets the frame or field recording, maximum recording rate, and picture grade for alarm recording individually for each camera number. When setting “– – –” for the recording rate, alarm recording is disabled for that camera number.

Select “View” and display the preview screen to check the settings you have set.

The recording rate set for normal and alarm recordings are the maximum number of frames. The number may decrease depending on the number of cameras used for recording.

The field recording and frame recording can be mixed. However, when the total number of fields and frames becomes nearly 120, the recording may not follow the setting. The priority of the recording rate setting is, frame recording > field recording > large recording rate > small recording rate > small camera number > large camera number.

Make sure to check the settings in the preview screen after making the recording settings.

When the picture is recorded at the maximum recording rate, a picture from the camera that is not currently used for recording cannot be checked through communication.

When setting the frame recording, the recording rate display in the preview screen turns green.

The recording rate display turns red when the total value exceeds 120 pps.

step3. Select motion detection recording.

Alarm: Starts alarm recording when the motion is detected.

Normal: Starts normal recording when the motion is detected. The recording is executed at the picture grade and the recording rate set for normal recording. The recording is not registered in the alarm list.

Data is recorded in normal recording area when the main device is partitioned.

Set alarm trigger on step 8 to “MD-A,” “MD-B,” “External / MD-A,” or “External / MD-B.”

In case of recording pattern A, you can start normal recording by pressing the REC/REC STOP button while the unit does not perform motion detection recording.

In case of timer operation, normal recording is not performed and the unit turns to stand-by mode for motion detection. Recording is performed only by the camera which detects motion.

For normal recording due to motion detection, <Alarm Camera Setting> is not used and recording is performed only by the camera of which the motion is detected.

For alarm recording due to ground of rear terminal, recording is performed by the cameras set in <Alarm Camera Setting>.

When motion detection recording is set to “Normal,” <Alarm Camera Setting> cannot be set. To change <Alarm Camera Setting>, switch the motion detection recording to “Alarm” once.

When you set the alarm recording trigger to “External

&MD,” normal recording due to motion detection is performed only during the rear terminal is grounded.

step4. Set the alarm mode.

Alarm CH: When alarm signal is input, performs alarm recording only by the cameras set for alarm recording. When there is an input of alarm signals from multiple sensors, alarm recording is performed by all the cameras to which alarm signals are input.

When alarm recording starts during normal recording, normal recording pauses while alarm recording is performed.

Alarm Plus: When an alarm signal is input during normal recording, performs alarm recording by the camera and the recording rate set for alarm recording while all the other cameras perform recording at the normal recording rate. The available recording rate for alarm and normal recordings is up to 120 pps in total.

When you have set alarm recording mode to Alarm Plus and then change the alarm recording rate to the value exceeding the available rate, alarm mode changes to Alarm CH automatically.

step5. Set the pre-alarm recording time in “Pre-Alarm Duration.”

0 sec: Does not execute the pre-alarm recording.

The pre-alarm recording time display turns red when the actual pre-alarm recording time becomes shorter than the set time depending on the alarm recording settings.
