The term “inaccessible to the DVR” is used to denote data which the DVR no longer has access to. Sometimes this inaccessible data can be recovered, but it depends on how the video came to be inaccessible, how much recording has occurred since that time, and where the video exists in the filesystem. Learn more about how DVR Examiner is able to recover inaccessible and deleted data.

How can you verify that DVR Examiner is finding all the video on the drive? There are a few ways users can use empirical verification to be sure DVR Examiner is recovering all the evidence you need.
Depending on the file system of the DVR hard drive you are scanning, you may come across a distorted split frame video clip when previewing. At first glance, it appears the same video frame is displayed twice, however, what you are seeing is half of the frame displayed on the top and half of the frame displayed on the bottom.
We want to help make your video recovery process as seamless as possible, which is why we’ve included so many different ways to filter and review the clip list. In understanding how this filtering process works, you can save even more time when recovering valuable video evidence.
Within the DVR Examiner Clip List Grid there is a field for the “clip status”. If the filesystem you are processing with DVR Examiner has support for inaccessible/deleted files, the information on these files will be provided here. This field will provide insight into how the clip was stored on the hard drive, and whether or not you will be able to recover it with DVR Examiner by determining if the clip is available, accessible, inaccessible, partially inaccessible, or a clip fragment.
As technology continues to advance, home surveillance systems have become commonplace among commercial and residential properties alike.
With the release of DVR Examiner 2.4 we made significant improvements to the way reports are viewed and exported. With the new Report Viewer, you can view the clip list report directly within DVR Examiner, allowing the user to search the report, print the report, or export the report in various formats.
DVR Examiner 2.4 is now available to download! This newest software updates brings you updates and improvements across the program, as well as redesigned reporting features.
Although we have designed DVR Examiner to work directly from the hard drive, bypassing the need for the DVR itself, it may sometimes be necessary for you to work directly with the DVR to export video or determine DVR settings. Use these tips to help turn on a nonworking DVR.
