DEFRAG DATABASE

When alarm recording is performed repeatedly with Repeat Recording set to “ALL” or “ALARM LOCK”, data in the hard disk may become fragmented. Continued use of such data may cause files to split up and be recorded into free space, thereby giving rise to fragmentation or decay of data, which subsequently slows down the speed dramatically during hard disk searches. This is where the “DEFRAG DATABASE” feature comes into play in the maintenance of the hard disk.

1.Press the [MENU] button.

Opens the menus in accordance with the instructions

provided in Changing MENU Settings (page 17) in the sequence of “MENU” → “DETAIL OPERATION” → “MAINTENANCE” → “DEFRAG DATABASE”.

Useful Features Using a PC

Initializing the Hard Disk (“FORMAT”)

Recording may fail if there is insufficient space on the hard disk. When there is insufficient hard disk space, create a backup data and format the disk to create space for the recorded data. You are also recommended to “FORMAT” (Initialize) the hard disk on a regular basis to avoid data fragmentation.

1.Press the [MENU] button.

Opens the menus in accordance with the instructions

provided in Changing MENU Settings (page 17) in the sequence of “MENU” → “DETAIL OPERATION” → “MAINTENANCE” → “FORMAT”.

2.Select [MANUAL] with [S/T], and then press the [SET] button.

The DEFRAG DATABASE confirmation screen will be displayed.

3.Select [YES] and press the [SET] button.

The DEFRAG DATABASE function will be executed.

CAUTION

If the time for automatic execution is reached during recording, the recording procedure will be aborted and the database will be defragged. When the defragging process is complete, recording will be restarted automatically.

The defrag procedure should be run when searches take excessive amounts of time.

When the date and time of automatic execution arrives during alarm recording, the recording process will be ended and the defrag process executed. Alarm recording will not be restarted when the defrag process has ended (although it can receive new alarms.)

The manual defrag process cannot be executed when in the following operation modes:

During recording.

During the playback of recorded images.

When the timer is ON.

During DVD export.

EXTRNL: Indicates external hard disks.

(Only one can be connected.)

2.Select [FORMAT] with [S/T], and then press the [SET] button.

The FORMAT confirmation screen will be displayed.

3.Select [YES] and press the [SET] button.

The FORMAT function will be executed. When the formatting process has been completed, the “FORMAT SUCCEEDED” screen will be displayed. Operations will then automatically return to normal.

Precautions When Initializing the Hard Disk

As the hard disk capacity displayed on the screen is calculated as 1GB = (1024)3 bytes, a lower capacity than actually exists will be displayed.

All recorded events will be erased when the formatting procedure is executed. Make sure that all important events are backed up accordingly.

CAUTION

The hard disk cannot be initialized when in the following operation modes:

During recording.

During the playback of recorded images.

When the timer is ON.

During DVD export.

When a malfunction occurs with the hard disk.
