Extract text from Surveillance videos and reports (NVR)
To convert NVR Videos and reports to another format, you need NVivo or other Video software.
To convert other file formats to the "Proprietary Surveillance Video" file type, you need software like NVivo or a similar tool.
The .NVR file format primarily stores proprietary surveillance video captured by Network Video Recorders (NVR) from manufacturers like Rosco Vision Systems and NetSurveillance. Less commonly, it serves as a qualitative analysis report exported by NVivo software, or as a compiled firmware update for ALI Corp set-top boxes.
Video-based .NVR files are notoriously restrictive. Hardware manufacturers deliberately use undocumented, non-standard container formats to prevent tampering and lock users into their specific ecosystem. As a result, standard media players like VLC Media Player or Windows Media Player will fail to play these files. Users are often forced to install obscure, sometimes outdated desktop clients (like the NVSIP viewer) just to review their security footage. This creates massive headaches when footage needs to be shared with law enforcement, lawyers, or insurance adjusters.
To make the video usable, you need to convert .NVR files to standard formats like MP4 or AVI. However, because this is a closed, proprietary format, standard online video converters invariably fail to process it. For the NVivo variant, the file is structurally an XML document, making it easier to parse, but it still requires conversion to be read by non-NVivo users.
Standard converters fail because they cannot read the proprietary container headers. If our analysis detects a supported underlying or embedded format - such as raw H.264 video frames or structured XML data - viewing or conversion may still be possible.
Convert.Guru analyzes your NVR file, detects the exact format, and lets you read the text inside.
Users also converted DAV, CPV, MP4, ASF, H265, EXE, VP5, YUV, NAS, DVR and VLC files.
If you want to convert NVR file to MP4, NAS, DVR or VLC, you can use NVivo or similar software from the "Video Surveillance Recording" category. In the File menu, look for Save As… or Export….
To convert files to NVR, try NVivo or another comparable tool in the "Video Surveillance Recording" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NVR converter.
