Extract text from metadata and map files (NMD)
To convert NMD data files to another format, you need Hikvision Network Media Player or other Data software.
To convert other file formats to the "Surveillance Event Log" file type, you need software like Hikvision Network Media Player or a similar tool.
The .nmd file extension is heavily overloaded and used across several distinct, proprietary systems. Most commonly, it functions as a video surveillance metadata file generated by Hikvision digital video recorders (DVRs) or Hanwha Techwin WiseNet network video recorders (NVRs). In these systems, the .nmd file stores motion detection logs, timestamps, and event data linked to a primary video recording. Another widespread use is as a navigation map data file for NNG iGO GPS software. Less commonly, it acts as an engineering project document in Nemetschek Allplan software or as a compressed game data archive for the Supreme Commander Nomads mod running on the Spring Engine.
Users frequently encounter major challenges when trying to open or convert .nmd files because they are tightly locked to their parent hardware or expensive proprietary software. For instance, Hikvision metadata files are virtually useless on their own; they must be paired with the original video file and opened in the proprietary Hikvision Network Media Player. They cannot be opened directly in standard web browsers or consumer media players. Similarly, Allplan project files require a costly commercial CAD license to access the 3D geometry.
Because these formats are closed and hardware-dependent, direct conversion is challenging. If the file is an NVR metadata log, extracting the raw text data to TXT or CSV is the most practical conversion target, though you may lose hardware-specific time-sync markers. If it is a Nomads game mod file, it is actually a standard ZIP archive in disguise, meaning you can easily extract its contents to standard folders.
Most generic online converters fail to process .nmd files because they lack support for proprietary CCTV metadata or specialized CAD document structures. Often, only the original hardware or authoring software can properly read or export the data. However, convert.guru offers a pragmatic workaround. Just drag and drop your file to see what it is and convert it if supported. Our deep-scan analyzer will inspect the file's internal hex signature and show any embedded text or internal content. If our analysis detects a supported underlying format like a standard ZIP archive or plaintext XML metadata, viewing or conversion may still be possible.
Convert.Guru analyzes your NMD file, detects the exact format, and lets you read the text inside.
Users also converted MD, LCP, SAM and IMS files.
If you want to convert NMD file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Hikvision Network Media Player or similar software from the "Video Surveillance Metadata Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to NMD, try Hikvision Network Media Player or another comparable tool in the "Video Surveillance Metadata Storage" 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 NMD converter.
