CD-RW or to DVD+RW drive. Administrator's password is required to export
video.
The exported video will be named by the exporting date and time, and
classified by event type. Each recorded video will be exported into four files if
exported with digital signature, including *.gpg, *.avi (or *.drv; depends on the
file format you had chosen), *.sig and readme txt.
Make sure an external storage device is available and has been connected to
the appropriate port for video exporting.
