while the original files are raw data of the DVR’s recorded videos.
The DRV and original files can only be played back with the remote
monitoring software and DVRPlayer. Multiple-camera video can be played
back from one DRV or original file. The AVI files can be played back with
Windows Media Player. Note that if multiple channels are exported to AVI
files, each channel is exported to a separate file.

Users can export video clip with or without a digital signature. Set this item to
<Yes> to export with the signature file, or <No> to export without it.
Each recorded video with digital signature will be exported into four files,
including *.gpg, *.avi (or *.drv), *.sig and readme.txt. The *.gpg file name is as
the last eight MAC (Media Access Control) address of the unit.
For more information on verifying digital signature, see appendix DVR Player
in OSD Setup Manual.
