What is a DVR file?
A .DVR file is a video recording created by a digital video recorder. Many different surveillance systems use the .DVR extension. These include systems from WAPA, TVT Digital Technology, Grain Media, 247Security WAVE, and Pro-Vision Video Systems. Because each manufacturer uses a different internal format, a .DVR file from one system might not open in the software of another system. The .DVR extension also indicates a Microsoft Recorded TV Show created by legacy Microsoft Windows Media Center software.
How to open DVR files?
Most standard video players cannot open proprietary .DVR files. You usually need the exact software provided by the camera manufacturer. Forensics teams often use DVR Examiner to extract and play video from unknown DVR systems. For older Microsoft Recorded TV Show recordings, VLC media player can often play the video.
Inspecting and converting DVR files
Because the .DVR extension has multiple possible meanings, we recommend using viewer.online/dvr to identify the actual format of your file. viewer.online/dvr can analyze .DVR files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available. Once you know the exact format, we recommend file conversion to sensible target formats like .MP4, .MKV, or .AVI on convert.guru.
Summary
viewer.online/dvr is useful for identifying, inspecting, and understanding .DVR files without installing software or dealing with compatibility problems.
