If your DVR is not supported through DVR Examiner yet, you will be prompted to create a DVR Profiler report. These reports help us identify new DVRs that we haven’t encountered yet and are the first and most important step in getting your DVR supported. Without a DVR Profiler report, DME Forensics will have a much more difficult and time-consuming job of implementing your DVR.
DVR Examiner allows you to recover video and metadata from CCTV and surveillance DVRs including those that are password protected or damaged. Let’s walk through the best practices to get started with DVR Examiner, including some video clips that will help you get the most out of DVR Examiner for your investigations.
So, you’ve just been handed a hard drive from your boss who gives instructions to find all the vital information on a storage device. You are immediately excited for your first solo assignment, until you look down at the hard drive and think: “Now what do I do?”
A filesystem is a term that Magnet Forensics uses to refer to a specific family of DVRs. Families are often made up of several different lineages all combined, right? We see DVRs the same way. We deal with the internal computer components, namely mainboards and chipsets, that come inside the DVRs. Many people are surprised … Continued
Many DVR users believe that by deleting video through the DVR interface, they are rendering video unrecoverable. Fortunately for forensic investigators, this is not the case. In most instances, when video is deleted through the DVR interface, only the index (or accessibility) to that video is being deleted. Assuming the video itself has not been overwritten, DVR Examiner may be able to recover it.
We’re proud to announce the availability of Magnet OUTRIDER 3.1!
Triaging Mac workstations has never been easier with Magnet OUTRIDER for Mac. From importing NCMEC data to using keywords and searching browser history, OUTRIDER can uncover actionable evidence quickly.
Data recovery is a key function of DVR Examiner for all our users, despite varying case load and case nature. An efficient workflow, and the ability for users to customize the workflow they follow based on their particular case needs, ensures rapid time to evidence, and is a major focus as we release new versions of DVR Examiner.
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.
Hikvision-based systems store date/time metadata a little differently than other DVR filesystems, and when it comes to adding support for new DVRs into DVR Examiner, or recovering video manually for a laboratory case, understanding date/time information is critical.
