What is the purpose of .DAV formats and what types of files are typically saved in this format?

The .DAV format is primarily used for video files recorded by surveillance cameras. DAV stands for Digital Audio Video, and it is a proprietary format developed by the company Dahua Technology. Surveillance systems often generate video files in the .DAV format, which contain audio and video data captured by the cameras. These files are usually saved on digital video recorders (DVRs) or network video recorders (NVRs) used in security systems. The purpose of the .DAV format is to provide a compressed and efficient way to store video footage from surveillance cameras. These files can then be easily managed, archived, and played back using specialized software provided by Dahua Technology.

How can I convert .DAV files to more commonly used formats for easier compatibility?

The software will start converting the .DAV file to the selected output format.Wait for the conversion to finish: The time taken for conversion will depend on the size of the file and the speed of your computer.
