dav file description
File extension dav is mostly known to be used for a special video format from several digital video recorders (for example DVR365, DVR-1600HP, etc.) as well as CCTV security solutions from several different manufacturers, including DVR365, AlienDVR or Mace.
The dav file represents video recording in a specially modified version o MPEG format saved in the SightBoss Central Station software which is installed on the DVR.
These dav files are also encrypted so they cannot be played by standard media players with MPEG support. A special playback software (DVR365) is needed to view the footage. You may also need older MPEG codecs installed on your computer for the playback to work.
Note: It seems that the DVR365 family of video recorders was superseded by AlienDVR devices that offer better resolutions and video encoded using the H.264 codec.
The latest AlienDVR video recorders do not use the original DAV format and it appears the recordings no longer even use the dav file extension as well, but the standard mp4 or 264 suffix.
