What is an NVR file?

NVR files mostly belong to BlackVue Viewer. NVR files are used mainly as containers for video recordings from network video recorders. They hold encoded video data produced by systems that capture footage from networked cameras.

Video Recording: The file stores surveillance footage in a proprietary, encoded format.

Dedicated Playback: These files need special players, like BlackVue Viewer or other manufacturer‐supplied software, to be opened properly.

FilExt.com notes: A smaller group of NVR files use an XML structure and are meant for report data from NVivo. In these cases, the file holds structured information for qualitative analysis and can be processed with XML tools or imported into NVivo software. For additional details on the XML format, visit this page.

NVR file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened.
