The .DAV file is also known as Davoo video file. It is an MPEG based video file. The .DAV filetype is one of the more modern video file types. These files refer to the DVR365 video file format. The file format is used mostly in cases of the video footages from the CCTV (closed circuit Tele vision) cameras.

The file's structure bears resemblance to the modified version of MPEG compression and is structured to store the data in an encrypted format. This is done to ensure the safety of the footages given the nature of the use of this file type.
