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.

CCTV Analysis and Court Presentation Material

Train CCTVCCTV Analysis

Following an Affray at a railway station CCTV images from the station and an on board train system were used by the prosecution in the form of a DVD compilation. We were instructed by one of the defence teams to analyse the CCTV evidence and clarify images containing their client for presentation in court.

Having viewed the DVD compilation disclosed to the defence we identified that the original Digital CCTV images had been converted to the DVD format. This can introduce artefacts, reduce edge detail and sometimes even miss out recorded frames. (see more here and here) so we advised that a copy of the original material should be requested so that we could carry out our analysis on the best evidence.

We identified that the timestamp used by both systems was not synchronised which made relating what could be seen from each system difficult and possibly misleading and produced material to identify the difference.  We produced clarified video and a document containing all of the relevant video images as stills in pdf format with the position of their client highlighted.

“At one stage in the proceedings, it [the pdf document] was referred to as the ‘bible’.”

Testimonial

After the completion of the trial the instructing solicitor said;
“The stills were very useful in terms of the on board footage and both other defence counsel said that this allowed them to explore points which they would otherwise not have been able to. At one stage in the proceedings, it [the pdf document] was referred to as the ‘bible’. Thank you as ever for your sterling work – and turnaround. I know that I always find the way in which the material is sent very useful and easy to access / use in terms of presentation (despite my lack of computer know how). Thanks again for your hard work!”

Commendation for Video Analysis and Court Presentation

I attended a commendation ceremony a few months ago at Bedfordshire Police HQ for police officers and others who brought the perpetrators of a large scale Cash for Crash operation to justice.

The text of the Chief Constable’s commendation included the following textDavid Thorne receiving commendation for video analysis

Judge Kay said, I want to commend the diligence and professionalism of the police officers and others involved in this inquiry. It has been a long and tortuous process to piece together the web of fraud in this operation. There were tens of thousands of documents that had to be reviewed, assessed and evaluated. By their efforts, the police and others involved have brought to an end a fraud which would have continued for some considerable time after November 2006 if it had not been stopped. It would have led to further considerable losses for the motor insurance industry and, ultimately, for all of us.

I COMMEND David Thorne who went to enormous efforts to put together all the photographic and video evidence, which was invaluable as it was so important to the investigation.

 

David Farrell QC  previously wrote;

David Thorne worked in collaboration with the OIC and Counsel. As Leading Counsel for the Prosecution I was impressed with the skills and dedication of David Thorne. He was often required to change or amend presentations over night or even at Court. He did so with speed and accuracy. (Tweet this)

Furthermore, he made positive contributions to the operation, using his former Police investigative skills to review the photographic evidence in the context of his knowledge of the case and thereby provide in itself valuable evidence. For example, he was able to see photographic damage to vehicles the significance of which had not been apparent to the investigative team and when placed before the Jury substantially contributed to the strength of this Prosecution.

I have no hesitation in recommending David Thorne as a dedicated and skilled forensic multimedia analyst who provides a first class service.

There’s more to this than meets the eye…..

This is a topic which I covered in a previous blog post that I have resurrected as it is as true today as when I wrote it two years ago.

There is a problem in the Criminal Justice system which relates to how best to present/disclose video evidence.

On the one hand everyone wants an easy  method of displaying the video to the court when required and with the least fuss. So in many cases the material is converted and authored to DVD. But should we be interested in the quality of that video; how faithfully does it represent the recorded images or can we say that it doesn’t matter as the material is only to provide an overview. If we want to ensure that the court can understand specific details in the video then we will need to use the best version of the recording. This probably wont be the DVD.

What about a Forensic CCTV Analysis of that material? We would want to be sure that what we examine is a true copy of the original recording not a compressed version of it.

Here’s a previous article from a couple of years ago that highlights a part of this,

Storyboards

We have found that one of the most compelling methods of using video evidence is when it is in the form of a storyboard.

   We will take your video images and produce a document containing A4 size pages with typically six images per page. The images are produced in a chronological sequence and depending on the individual requirements the images may be all of the relevant images, a selection from a sequence or sequences from multiple cameras and systems.

We recently assisted an investigator who needed the video images in a format that could easily be used to show witnesses and interview suspects, he writes…

Operation Hovercraft
As part of an investigation into a large scale organised fraud I had seized CCTV videotapes for several dates from multiple locations. I needed to extract images of the offences taking place for use in obtaining witness statements and in suspect interviews and ultimately in any court proceedings. This task was made very difficult as the vast majority of the CCTV images were not time or date stamped.

   Demux quickly reformatted the tapes to DVD format with a time-code overlaid which allowed me to review and create a brief chronology of any relevant contents. Demux then digitised the relevant periods from the original tapes and created a storyboard of video stills to show the movements of those involved in chronological order, with the position of each person highlighted and colour coded. In addition they produced DVD’s containing video clips of each counter transaction.

   Their [Demux] background and expertise in this field has provided me with the material to effectively investigate the offences and will reduce the time required to interview witnesses and suspects.
