What is a DAV file?
A DAV file is a video created by a DVR365 or Dahua Technology digital video recorder (DVR), connected to a closed-circuit television (CCTV) surveillance system. It contains video that is saved in a compressed, encrypted format. DAV files can be played using the CCTV system that created them, as well as some specialized media players.
DVR365 and Dahua Technology video surveillance systems use one or more DVR cameras to record surveillance footage. For example, DVR365 systems may use DSD304, DSSD308, or DSD316 DVR cameras. The footage these cameras record is saved in DAV files.
DAV files are encrypted, to prevent unauthorized users from playing them, and meant to be played using the system that created them. However, some downloadable media players can play DAV files, and various tools allow users to convert DAV files to more common video formats, such as .AVI
NOTE: Many other companies sell CCTV systems that are rebranded Dahua Technology systems. These systems may also produce DAV files.
How do I open a DAV file?
You can open and play DAV files in Dahua Smart Player (Windows), which is available as a standalone application or as part of Dahua Toolbox. You can also convert DAV files to more common video formats using VidCoder (Windows).
