A DAV file is a proprietary video format created by DVRs and security cameras, especially from brands like Dahua. It’s designed for recording and storing surveillance footage, but it isn’t widely supported by standard video players. That makes watching or sharing DAV files a challenge. Most users need to convert DAV files to a more universal format like MP4, which works on Windows, Mac, Android, and almost any media player.
In this article, we will share everything you need to know about working with DAV files. From selecting the right media player to mastering DAV-to-MP4 conversion across desktop, web-based, and Android platforms—all for free.
Part 1. Why You Need a DAV File Player
DAV files are created by DVRs and surveillance cameras for efficient storage of surveillance footage, but standard players like Windows Media Player or VLC do not natively support this format. Without a dedicated player, you may encounter playback errors, missing audio, or even be unable to view the recording at all. Using a professional DAV player ensures stable playback and allows you to safely view or export the recording.
For greater flexibility, many users convert DAV files to MP4 format. MP4 files are smaller, easier to share, and compatible with almost all devices. Since many DAV players have built-in conversion tools, you can easily convert limited surveillance data to a universal format for easier editing and viewing.

| Created By | DVR / Security cameras | Standard video formats |
| Compatibility | Limited to proprietary players | Works on almost all devices |

| Editing | Difficult, requires special software | Easy with video editors |
