Emergency Recording Setup

This item is used to set the emergency recording settings. When the EMERGENCY terminal is grounded by the alarm sensor while both of the MAIN switch on the rear panel and the POWER button on the front panel are turned ON, emergency recording starts automatically overriding all the other settings even during timer recording or the unit is in stop mode.

Emergency recording is not performed while the MAIN switch or POWER button is turned OFF or while timer recording stand-by mode.

The setting of the <Recording> menu cannot be changed during normal recording or alarm recording. To change setting during recording, stop recording in case of normal recording. In case of alarm recording, when the “Alarm Input” in the <Recording> menu is set to “Off,” the alarm input is not accepted for 5 minutes. When you stop recording during this time, the setting change of the <Recording> menu is available.

Emergency recording

1)The picture grade is “L6-30KB” and the recording rate is set to the value obtained by dividing the maximum emergency recording rate by the number of specified cameras.

When the LPA area is set in the main device, the emergency recording data is stored in the LPA area and is automatically locked in 512 MB unit including the emergency recording data in order to prevent overwriting the data.

In LPA area, the data is always recorded at the rate set for alarm recording regardless of an input of the emergency signal. Therefore, when the emergency recording is started from the mid-part of the data block, the data recorded before the ground of the EMERGENCY terminal is stored in the locked area along with the emergency recording.

When you set the long pre-alarm recording time without setting the LPA area, long pre-alarm recording is carried out using the internal memory for pre-alarm recording, so long pre-alarm recording is performed for the short time period regardless of the setting.

When emergency recording is carried out using the LPA area, data is not stored chronologically and alarms are listed out of sequence. Be careful when searching for the desired picture.

When power failure occurs during emergency recording,

the emergency recording is cancelled after returning from the power failure.

When emergency recording is carried out during timer

recording, the end time of the timer recording is extended until the emergency recording is completed. The timer recording is finished after completing the emergency recording.

2)Cameras to be used

Cameras which are set in <Emergency Recording Setup> are used.

3)During emergency recording:

•“E-REC” is displayed on the screen in red.

•The camera number buttons and camera number dis- play on the screen which are used for emergency re- cording flash.

4)Emergency recording is registered in the alarm list and displayed in magenta.
