These recorders capture video images that have been recorded by CCTV (closed circuit TV) cameras in a modified MPEG file format, and is commonly used for recording video captured by CCTV cameras in China (where many security cameras and DVR’s are manufactured). About the DAV format:ĭAV is a proprietary encrypted format created by DVR365 digital video recorders. Please note, these instructions are intended for those using a Windows based operating system. So in order to alleviate some of that confusion and frustration, here’s a quick guide on how to download and convert DAV files from a DVR or NVR.
Those files may need to be converted a second time to nullify the encryption. It has gotten a bit more challenging since the days when you could just retrieve a security tape from a VCR. These DVR files are now encoded as encrypted files with codecs that make them rather difficult to use in standard video players or editors. Even if you convert the file once to an AVI or MPEG file, many traditional media players such as Windows Media Player won’t be able to play them, as they are a rather obscure and specific video format. So at some point you’ll need to download and access that footage from your DVR or NVR. If you have a CCTV security system and either your home or office is broken into or an incident has occurred, the video of that crime has to be given to management or authorities.
