DVR Examiner V2.6 released

Filter for a specific time of day across a date range.

DVR Examiner filter on time of dayWhen recovering video from a DVR you may find that you want to focus on a specific time period which you can achieve with the scan or clip filters, this gives you all of the material between the start and end time. DME Forensics have now improved that feature by adding the ability to filter for a specific time of day across a date range.

This will be very useful to examiners who are looking for events across a date range but only during specific times such as business operating hours.

The Basics of Reverse Engineering a DVR Filesystem

Reverse engineering the CCTV DVRThe Basics of Reverse Engineering a DVR Filesystem

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. The ability to read these filesystems is not something that DVR Examiner does automatically – first someone from our Advanced Technical Services (ATS) team has to reverse engineer each filesystem implemented within the program. Only after completing this lengthy process can DVR Examiner recover the video evidence from surveillance DVRs. This post touches on some of the first steps our team takes to understand how each different filesystem works.

Important to note that this is intended to make reviewing easier and is not intended to confirm what the correct aspect ratio of the clip should be nor does it effect any files that are exported as these will be exported as they were recorded.

Introducing the DVR Examiner Updater

The DVR Examiner Updater application allows you to continuously update your existing version of DVR Examiner with newly supported filesystems and improvements to existing filesystems as we finalize them. Basically, this new application brings you system compatibility with new DVRs, faster.

DVR Examiner - filesystem updater

There are a few ways to run the DVR Examiner Updater. If you are connected to the internet, you can click the link on the notification screen within DVR Examiner (pictured below). Otherwise, use the Windows start menu or launch the DVRExaminer_Updater.exe from the DVR Examiner installation folder (usually C:/Program Files/DVR Examiner).

DVR Examiner - version window

The process for updating your filesystem database version will depend on whether or not your work station is connected to the internet. If you have an internet connection, you can download and install Filesystem Database Updates (FDUs) from the DVR Examiner Updater. The Updater will allow you to download a new FDU from the portal and then install the new FDU immediately, so that DVR Examiner has the most current filesystem code to run from.

If your work station is not connected to the internet, you will have to use an internet connected computer to download the the latest FDU from the Support Portal and move the FDU to your work station (using a flash drive). After moving the FDU to your work station, you can select the “Add FDU” option in the top bar of the DVR Examiner Updater. You will then be able to install that FDU so DVR Examiner can have access to the latest filesystems and filesystem improvements.

Note: if a FDU does not appear in the grid of the Updater after being added, you can refresh the Updater Grid by clicking the “Check for Latest FDUs” button.

For more information on using the DVR Examiner Updater, check out this short training video (turn on your speakers).

We are excited to bring you this new feature of DVR Examiner to help bring you filesystem updates at a faster pace. If you encounter a filesystem that is not supported by DVR Examiner, be sure to submit a request to the technical support team at support@dmeforensics.com. Please include the name of the filesystem in your email.

Haven’t updated DVR Examiner to 2.2 yet? Click here to download the latest version and get access to continuous filesystem updates.

Recovering Deleted DVR Video with DVR Examiner

DVR Examiner - recover deleted video from a CCTV DVRMany 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.

DVR Examiner can recover deleted DVR video by using the “inaccessible recovery” feature in DVR Examiner. What does “inaccessible” mean? In short, it refers to video that the DVR no longer knows how to find. A less precise term for this would be “deleted”, but there are several ways a video can become inaccessible other than deliberate deletion by the user. The most common way would be that the DVR was operating normally and simply needed more space for newer video.

When you initially scan a HDD, one of the first screens that comes up is the Supported System Identified screen. This screen displays all the features that DVR Examiner supports for this particular filesystem. If inaccessible recovery is supported, the “Inaccessible” icon (on the far left) will be highlighted in orange.

DVR Examiner - Inaccessible video recovery

DVR Examiner supports two inaccessible recovery types. The first type, simply called “Inaccessible”, refers to the ability of DVR Examiner to locate large segments of deleted video that the DVR no longer recognizes. For example, when a disk is reformatted or deleted, if no additional video is recorded, all the original video is largely intact but simply missing index entries. The second type, “Frame Level Inaccessible” refers to the ability of DVR Examiner to recover very small segments of video which may have been partially overwritten by newer video. This is a much more complex and complete recovery type – we’re often able to recover some video from weeks or months in the past that was never actually overwritten. Keep in mind that either recovery type will typically result in a slower scan process.

DME Forensics hope to be able to add inaccessible recovery to as many filesystems as possible. If you would like to request inaccessible recovery be added for a specific filesystem, you can do so by sending them an email at support@dmeforensics.com. Please include the name of the filesystem in your email.

Due to limitations within specific filesystems, inaccessible recovery will not always be able to be implemented within DVR Examiner. However, this typically does not prevent their Advanced Technical Services (ATS) team from being able to recover the data manually. If you have a specific case where inaccessible recovery is crucial, please contact DME Forensics to discuss potential options.
