What is DVR Examiner?

DVR Examiner is a software solution for acquiring video and metadata from CCTV DVR Hard Drives in a forensically sound manner. Whether in the field or in the lab, DVR Examiner allows law enforcement and other forensic professionals to bypass DVR passwords and archaic menus to quickly extract evidence from the DVR hard drive directly. No need to carve out the data and decipher the time stamps and camera streams.

Data Recovery software is often capable of seeing the data on a hard drive but without specialist knowledge of the filesystem used by an individual DVR manufacturer, it can be extremely time consuming to carve the data and piece it together into a playable video with any relevant metadata tying up specialists on a task that can be easily carried out by DVR Examiner.

DVR Examiner vs Traditional Recovery

The video here shows how quickly you can recover CCTV video using DVR Examiner compared to the traditional method using the DVR user interface.

You can also export the video in an open format using DVR Examiner which is rarely an export option with DVRs.

So Why Would You Need a Software Solution?

  • No need to power on the DVR even if you do have the power lead
  • No admin or user password required
  • No remote control required
  • No need to use the DVR user interface.
  • No need for export media such as a USB stick or discs.
  • No need to retain the DVR once hard drive is imaged and confirmed as compatible with DVR Examiner.
  • Recover video for periods that the DVR system thinks is no longer available*
  • Export a selection of the video content in either the proprietary format or a wmp compatible format or both.

The video below demonstrates the time saving when using DVR Examiner over traditional recovery methods. As the list above shows there are more benefits to using the software than just speeding up recovery.

*If DVR Examiner indicates that the recovery of inaccessible data is supported for a specific filesystem then this is an additional option which may recover data that has been accidentally or maliciously deleted via the DVR user interface or data now out of the systems retention policy.

DVR Examiner FAQs

Can I submit a request for a specific DVR model to be supported by DVR Examiner?

Absolutely! We are constantly looking to identify new models of DVRs that users are seeing out in the field. In an effort to better prioritize our list of DVRs, we ask that you submit a DVR Examiner Profiler Report. You can do this either directly in DVR Examiner when you create the Profiler Report, or by uploading the complete report to our Support Portal. Implementing a new DVR model is a very complicated task. Depending on the file structure and the proprietary nature of many DVR models, this can take some time. Once we receive your Profiler Report we will update you on the progress.

What is the minimum spec for my hardware to run DVR Examiner?

The following are minimum required specifications:

– Windows 10, 10 Enterprise

– 16 GB RAM or more

– Dual Core Processor or better

– 1366×768 minimum recommended screen resolution

Notes:

Windows 7

Due to Microsoft no longer supporting Windows 7, DVR Examiner will not be supported on Windows 7 machines.
While DVR Examiner may run and function normally on Windows 7, we cannot guarantee this. DVR Examiner requires certain certifications and Windows updates to perform, and most versions of Windows 7 will not have these requirements.

Windows Server

DVR Examiner requires the Windows Media Foundation to be installed. In many server installations this pack is not installed and DVR Examiner may not install or function properly. Windows provides server specific Media Foundation packs that can be installed on your server. If you are attempting to install DVR Examiner on a Windows Server machine, it is recommended to install Windows Media Foundation first.

Running DVR Examiner on a Non-Internet Connected PC

DVR Examiner can be run on both an internet connected and a non-internet connected PC. However, with new versions of DVR Examiner, it may be necessary to update Windows to get DVR Examiner to install and perform correctly.

It is recommended to always keep Windows up to date, even on a non-internet connected PC.

Please consult your IT department about keeping non-internet PCs up to date.

What happens if I lose my DVR Examiner dongle?

Please contact us and we will provide a quotation for a replacement dongle, your original dongle will be deactivated.

Do you support [Insert Make/Model] DVR?

At this time we do not have a list of known makes and model that are supported in DVR Examiner. Please feel free to test our compatibility through our free trial and submit a DVR Feedback Report. For more details see the next question.

How many DVRs does DVR Examiner support?

We get this question a lot, and the simple answer is: we don’t know. DVR Examiner targets and supports a specific DVR filesystem, or DVR system board. Each board has its own unique way of processing and storing video, and a single version of a board could be found in multiple models by multiple manufacturers. For example, we have found a single particular board in numerous Lorex, Honeywell and Ganz models. As a result of this, it is very difficult for us to determine how many makes/models are supported.

We ask for user feedback by submitting a DVR Feedback Report on our Support Portal in order to better capture this information so we can publish a ‘known supported’ list.

The software change log lists DVR brands and systems that are currently supported.

How will I know if there is a new version of DVR Examiner?

The software prompts you to download new versions as long as your workstation is connected to the internet. We understand that very often forensic workstations are not connected to the internet so we also publish a blog post detailing update news and this can be sent to you as an email.

Is it possible to try out a full functioning version for estimates on how long the complete process takes?

In an effort to provide you with a full experience during the free trial, we provide multiple sample files on the Support Portal that are full featured and give you a demonstration of all the functions of DVR Examiner. We feel this provides all the needed information for the evaluation process and as a result, we don’t allow fully functioning trials. Preview and Export options are restricted in the Trial Version to only previewing and exporting the first clip (Clip ID #1) on any hard drive. If you have a concern that is not addressed, please feel free to contact us.

The software is sold as a 1 year subscription. Does the software continue to function after the year is up?

After a year you cannot scan new cases if you do not renew. However, you can use it on existing saved cases on the version you are currently on.

Am I allowed to install DVR Examiner on multiple computers?

Yes, and we encourage this. The DVR Examiner dongle is your license key and must be plugged into the current system running DVR Examiner. We designed it this way to allow for the greatest flexibility, users can install DVR Examiner on as many computers as they need. If you wish to have DVR Examiner operate on more than one computer at the same time, additional licenses (dongles) may be purchased.

Is there training available for DVR Examiner?

There is now in-person and online training available, please see the DVR Examiner training page.

What if I only want to process one DVR Hard Drive?

For examiners where there is an infrequent requirement to justify a full licence there is a single-use licence.

If you want the same great features of DVR Examiner but would also like to be able to replay open and proprietary video files and download Ring, Arlo and Blink recordings then please take a look at WITNESS.
