User' s Manual
It is possible to archive video to an external USB-IDE hard disk drive. The archived images can
be viewed on computers running Microsoft Windows 98, ME or 2000. Refer to the Appendix A
— USB Hard Disk Drive Preparation for information on preparing the external drive for
archiving.
CAUTION: Do NOT disconnect the USB cable or the power from the external
drive while archiving video. If the external drive is shut down or the USB cable
is disconnected while archiving, THE DVR SYSTEM MAY NOT WORK
NORMALLY OR THE EXTERNAL DRIVE COULD BE DAMAGED, and you will get
an error message the next time you try to archive. You will need to power down
the DVR and restart it to get rid of the error message.
Once the file system of the USB-IDE hard disk drive has been corrupted, this
error message cannot be dismissed. Even after restarting the DVR it may
automatically restart while preparing a backup. You must recover the file
system by using the recovery program, or you must reformat the hard disk
drive.
You can choose to archive video from the first to last recorded images, or you can set the start
and stop times and dates. You can also select which camera you wish to archive.
Highlight the File Name box and press the
button. A virtual keyboard appears. Enter a file
name for the video you are archiving and select Close. The DVR will automatically add the
camera number (for example "01") and ".exe" to the file name. If you want to save the file in a
specific folder, enter the folder name followed by a "/". For example: "folder/filename"
Once you have given the video a file name, highlight the Start button and press the
button.
The DVR will display the USB drive capacity, the backup file size and ask if you want to
continue.
NOTE: Do not back up files larger than 2GB.
During archiving the title bar will first display Preparing backup, then it will show the
progress. Once archiving is complete, the title bar will display Backup is completed.
You can end the archiving process at any time by highlighting the Cancel button and pressing
the button.
You can use other functions on the DVR while video is being archived. To do this, highlight the
Close button and press the button. You can return to the Backup screen at any time to
check the progress.
Refer to Appendix B — Reviewing Backup Images for instructions on how to review the images
you have archived.
NOTE: Any recorded audio will not be backed up.
