At the heart of DVR Examiner is its ability to read a proprietary DVR filesystem and display and extract the data contained on the device. This post touches on some of the first steps our team takes to understand how each different filesystem works.
There are several different methods commonly used when recovering video evidence from DVRs. DVR Examiner is a useful tool because it allows you to recover the video fast – usually much faster than traditional methods – and in a forensically sound manner. Still, there is no one solution for every case, and it’s important to know what to do when DVR Examiner doesn’t work as you might hope.
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.
DVR Examiner 2.5 is now available to download! This latest update includes more filesystem improvements and bug fixes than any previous release.
The “aspect ratio” button in DVR Examiner 2.5 is designed to detect cases where the frame appears to be significantly too short, and will adjust the frame so that it appears much closer to the correct size and aspect ratio. Learn more in our latest blog.
