Existing User Testimonial

During an on going major investigation our team were tasked with gathering CCTV evidence from an unbranded DVR that had an unknown password. After several failed attempts to locate the required information to allow access to the DVR contact was made with Demux Video Services Ltd, regarding DME Forensics, DVR Examiner.

Within 48hrs from point of order we received the product; this allowed us immediate access to the required CCTV Footage by extracting the data direct from the DVR’s HDD.

With out Demux Video Services Ltd and DME’s DVR Examiner we would have faced lengthy delays and may even have been unable to retrieve the evidence that we required.

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 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 piece together the video and meta data tying up specialists on a task that can be easily carried out by DVR Examiner.

Using the DVR to export video can take upwards of three weeks on some systems. With only a few clicks, DVR Examiner allows you to retrieve video from the DVR hard drive directly. This forensically sound workflow saves you and your agency the headache of manually exporting video to flash drives or CDs!

Spend more time viewing the images and less time acquiring them.

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.

*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.

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.
