Data Recovery with DVR Examiner: Accessible, Inaccessible, and VERY Inaccessible
Data recovery with DVR Examiner works by reverse engineering the many different DVR filesystems to locate and extract video footage. Most DVRs use a proprietary filesystem. Sometimes this is in conjunction with a known filesystem, often Ext 2 or 3, but even in these cases the video data is typically located in a large proprietary partition which won’t be recognized by conventional computer forensic tools. However, if you take a closer look at these “unallocated” spaces, you may find some familiar structures and multitudes of highly compressed video data.
