When the pre-alarm recording time setting exceeds the maximum pre-alarm recordable time, the pre-alarm recording time display turns red. Set the time within the maximum recordable time. You can use the recording rate or picture grade for adjusting the pre-alarm recording time. Even if the time is set exceeding the maximum recordable time, the actual pre-alarm recording is performed for the maximum recordable time.

When the alarm area is set, the alarm recording and pre- alarm recording are made in the alarm area. To playback the recorded data, set the <Select Source Device> ( page 39) to “Alarm.”

In the case that the alarm recording mode is set to “Alarm CH,” recording with all the camera numbers set for alarm recording may not be possible when pre-alarm recording is carried out during normal recording.

To perform pre-alarm recording by all the camera numbers set for alarm recording, use alarm recording mode without using normal recording. To perform with normal recording, set “Alarm Mode” to “Alarm Plus.”

Pre-alarm recording is carried out at the recording rate of normal or alarm recording set for that time period and with the picture grade set for alarm recording.

Recording time for pre-alarm recording is based on the alarm recording setting. For pre-alarm recording which is started during normal recording, the recording time may be shorter than the specified time depending on the normal recording setting.

step6. Set the alarm recording time in “Post-Alarm Duration.”

Manual: Continues alarm recording until the ALARM IN terminal is not grounded.

step7. Set the recording camera for each sensor connected.

Select “View” and display the overview screen to check the settings of all the sensors.

The multiple camera numbers can be set for one sensor input.

step8. Set the trigger of alarm recording for each sensor connected.

External & MD-A:Starts alarm recording when the motion A is detected while the ALARM IN terminal is grounded.

External & MD-B:Starts alarm recording when the motion B is detected while the ALARM IN terminal is grounded.

External: Starts alarm recording only when the ALARM IN terminal is grounded.

External / MD-A:Starts alarm recording when the ALARM IN terminal is grounded or the motion A is detected.

External / MD-B:Starts alarm recording when the ALARM IN terminal is grounded or the motion B is detected.

MD-A:Starts alarm recording only when the motion A is detected.

MD-B:Starts alarm recording only when the motion B is detected.

When setting the trigger to “MD-A,” “MD-B,” “External / MD-A,” “External / MD-B,” “External & MD-A,” or “External

&MD-B,” the motion detection function becomes active immediately after exiting <Set Recording Pattern A (Normal/Timer) to D (Timer)>. To stop the input of alarm signals, set the “Alarm Input” setting in the <Recording> menu to “Off.”

step9. Set the PTZ camera preset for the sensor of which trigger is set to “External” on step 8.

Preset 1 to 16: When the ALARM IN terminal corresponding to the sensor is grounded, the angle of corresponding camera is adjusted to the preset point set on this step. (The camera angle is not adjusted when the trigger is set to the item other than “External.”)

: Does not adjust the camera angle.

Select “View” and display the overview screen to check all the settings set on steps 8 and 9.

Alarm recording

When the alarm recording or the emergency recording is executed during timer recording, the end time of the timer recording is extended until the alarm recording or the emergency recording is completed.

When the alarm recording trigger is set to “External / MD-A” or “External / MD-B,” the priority is given to the latest alarm input.

When the alarm recording trigger is set to “External / MD-A” or “External / MD-B,” and the alarm recording time is set to “Manual,” the alarm recording stops 2 seconds after the input of motion detection even if the ALARM IN terminal is being grounded. (When the alarm recording time for this recording according to the motion detection is set to “Manual,” the actual recording time is 2 seconds.)

When power failure occurs during alarm recording or emergency recording, the alarm recording or the emergency recording is cancelled after returning from the power failure.

When alarms are input for multiple sensors at the same time, not all the alarms may be registered to the alarm list.

Frame recording and field recording

In NTSC signal system, one picture is consist of two screens, odd and even. The unit records only the screens of odd in case of field recording. In case of frame recording, both of the screens (odd and even) are recorded.

Frame recording is suitable for storing the data in the high picture quality, however, the data capacity is twice as large as that of the field recording of the same picture grade (1 frame = 2 fields). The picture may be looked like vibrating because one picture is consisted by two screens.

Alarm Input

This item is used to stop the alarm input manually. When setting “Alarm Input” to “Off,” the alarm input is stopped for 5 minutes. To set the <Recording> menu while the alarm recording occurs continuously, stop the alarm input first to stop recording. “Alarm Input” function is available for ALARM IN terminal on the rear panel, motion detection, emergency recording, and communication port. To cancel the prohibition of alarm input manually, set it to “On” and then exit the <Recording> menu. It is cancelled automatically after 5 minutes.
