DVR Examiner – Latest Versions (Jan 2020)

Are you up to date?

Running the most up to date version of the software with the latest filesystem database means you will be getting the very most from your software.

Filesystems and filesystem specific functions that weren’t previously supported may now be included. If in the past you have come across a DVR filesystem that wasn’t supported and you submitted a profiler you should have been updated by email when that had been included. I would encourage users to submit profiles as this is the best way for the developers to know what systems users are examining and how to prioritise their resources. Even if you didnt submit a profiler it might be worth checking those previously unsupported DVRs using the latest software to see if it can assist you.

At the time of writing these are the latest versions;

DVR Examiner Version 2.8.2

Released 2019-12-20

DVR Examiner Filesystem Database (FDU) Version 3.0.9851

Released 2020-01-16

New Video Evidence Recovery and Analysis Training and Software

We are very pleased to be able to offer investigators and examiners some new software and training.

In addition to the DVR Examiner software we are now able to supply iNPUT-ACE software and the Cellebrite VERA course.

I will be putting up more information on the website soon but here are a few words about the software and training;

iNPUT-ACE and iNPUT-ACE | Lite software packages provide investigators with powerful tools to manage their digital video evidence. The two dynamic software programs work alongside each other to expedite any case that involves video evidence: from video playback, to clip extraction, enhancement, analysis, report writing, and much more.

Video Evidence Recovery and Analysis (VERA) Course (To be held in the UK)

The Video Evidence Recovery and Analysis Course (VERA) is five-day intermediate level course designed to introduce investigators, examiners and analysts to digital video technology and to meet the specific needs of the digital video examiner and analyst.

Students will learn proper methods to interrogate digital video evidence while receiving guided instruction throughout the process of recovering valuable evidence from video images. The course will also focus on specialized investigative techniques for the examination of video to explore issues relating to the use of force, speed estimation and identification. A variety of DVR, body-worn and in-car video sources will be examined in depth, testing data acquisition, file identification, image accuracy, video processing work flows and report writing.

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.

Feature Focus: DVR Examiner 2.5 Aspect Ratio

A new feature in DVR Examiner 2.5 helps review material that has been recorded at half the frame height by adjusting the aspect ratio for the preview.DVR Examiner 2.5 Aspectb Ratio

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.

DVR Examiner Training

DVR Examiner User Certificate TrainingWe are very pleased to announce that there will be two DVR Examiner User Certification classes run in the UK in September 2018. Tutors will be from the software developer DME Forensics.

As a forensic investigator, you often face time-sensitive situations, where the accuracy of your evidence can make or break a case. By using DVR Examiner, you can save both time and money in these situations, but it helps to know how to use the tool effectively.

While DME Forensics put a lot of effort into making DVR Examiner simple and easy to use, it is still a very complex tool with a lot of powerful capabilities. Understanding the basics behind how DVR Examiner works, as well as the best practices and methodologies for the software can be critical in any investigation. With training, you can fully maximise DVR Examiner’s potential to assist in your case.

The User Certification Training guides users through the process of how DVR Examiner works, from DVR acquisition to complete video recovery and data output. We will go over all of the newest features of DVR Examiner, including the recovery of deleted (inaccessible) video. Students will explore how to make the most of DVR Examiner in real world scenarios, and how to defend your evidence in a court.

This training is especially important if you’re likely to testify to the work done with DVR Examiner. Being a certified user can be critical to DVR Examiner in court. Opposing counsel can be very diligent in ensuring the accuracy of evidence being entered, so being able to explain your methods, along with how DVR Examiner operates, can help you defend your evidence.

Location: Between Manchester and Liverpool.


Course A – 8:00 Monday 24th September to 12:00 Wednesday 26th September

Course B – 13:00 Wednesday 26th September to 17:00 Friday 28th September

Certificate: When the student is present for all sessions and has passed all exams, they will receive a certificate of completion. When the attendee has actively taken part and was present for all sessions but failed to reach the required standard in the exams they will receive a certificate of participation.

Training – VFSource User Training February 2018

Last week we were in Merseyside with Jeff Hunter of Salient Sciences training video examiners from various UK police forces. It was interesting to hear the different ways that video material is being processed and presented for prosecutions.

Providing training to video examiners

Jeff, who is the Principal Engineer at Salient Sciences, was particularly interested to speak with users to gain an insight into their real-world issues when working with multimedia evidence as he can influence the future development of the software to assist users to work more efficiently and effectively.

The course was attended by new and experienced users and the following comment highlights why training is so important…..

“I can say that I really enjoyed the course. It has re-ignited my interest in working with digital media.  I always knew the software could do more than I was using it for.  I can also say that the first job this morning has already seen my new skills in action.” Course attendee DP of Derbyshire Constabulary.

Both the VFSource and VFPro software provide examiners with the tools to work with proprietary and non-proprietary video and audio material.

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.

If you are involved in the recovery of video from CCTV DVRs and you are not yet a user of DVR Examiner you can obtain a free trial here and discover how much easier it is with a tool specifically built for the task.
