ALARM RECORDING

Alarm recording commences upon either of the following conditions:

•An ALARM IN terminal is triggered by an alarm sensor

•A camera detects motion

When there is an alarm:

1)The recorder switches to its preset recording intervals. Refer to Alarms in the Pro- gramming section for alarm settings.

2)An index signal is automatically stored in memory when alarm recording begins. Refer to the Playback section for reviewing alarm recordings using the index search.

3)If the unit receives a new alarm signal while in the alarm recording mode, the unit completes the alarm recording session initiated by the new signal.

4)If the unit receives an alarm signal at an ALARM IN terminal while settings are being made on the on-screen menus, the unit exits the menu screen and begins alarm re- cording.

5)The unit stores a data entry in an Alarm List of the time it receives the alarm signal. Refer to the Playback section for reviewing images from the Alarm List.

6)Regardless of the display mode, camera number buttons flash for those cameras making alarm recordings. The Alarm Recording indicator flashes on and off during alarm recording and stays on at the completion of alarm recording. If the DISPLAY MODE is set for values other than 5 or 6, an Alarm Recording number will automati- cally appear on-screen while the unit is running in alarm recording mode. The maxi- mum Alarm Recording number is 9999.

￿

At the end of alarm recording, the unit returns to the same recording intervals that were in effect before the alarm recording.

When in the alarm recording mode, the unit records for the entire alarm recording du- ration even if the end-time specified in a timer program has been exceeded. Alarm re- cording also continues as long as motion is detected within the active area established for motion detection. When motion stops, alarm recording continues for the time set in the A-REC DURATION setting.

There may be cases when the recorder’s built-in motion detection function does not operate properly due to the condition of the input video signal or other factors. There may be such operation errors when the recorder is connected to a system that uses the recorder’s detection function to send a warning signal.

If the recorder is programmed for pre-alarm recording, pre-alarm recordings are made of all cameras since it is not known which camera will have an alarm. After an ALARM IN terminal is triggered, however, only those cameras designated in the RECORD ALARM setting will make alarm recordings. This means that during playback the num- ber of cameras displayed may differ for pre-alarm and post-alarm recording.
