CCTV DVR DATA RECOVERY

CCTV DVR Recovery Process

WHAT IS CCTV DVR DATA RECOVERY?

CCTV DVR data recovery is the process of recovering digital video recorder (DVR) data, securing it, and using forensic recovery methods to produce copies. Forensic tools do not affect the integrity of the original storage medium. Additionally, our DVR hard drive recovery processes and procedures are based on best practices accepted in the forensic scientific community. In fact, law enforcement agencies around the world use these same processes.

DO NOT ATTEMPT RECOVERY YOURSELF!!​

Overuse, disassembly, recovery attempts, and other changes to the DVR can permanently destroy its data. Accidentally or intentionally deleted video files are both data loss situations. On the condition that hard drives and storage devices are physically damaged, files need to be carefully recovered. In order to restore deleted videos accurately, investigators rely on qualified forensic recovery by a video forensic expert.

RECOVERY METHODS

Generally, the DVR data was intentionally or accidentally deleted from recording space restriction by malicious intent. On the other hand, the DVR data may have been damaged due to vandalism, fire, or other physical data corruption.

DVR Hard Drive Recovery

ON SITE RECOVERY

Our video technicians receive extensive training with accredited agencies. These agencies educate on how to recover CCTV DVR video recordings and preserve digital integrity. Because these systems might be too heavy or fragile to ship, our team can travel to your location for pickup.

LAB RECOVERY & HARD DISC RECOVERY

Once received, we perform a scanning process of the DVR's internal hard drive. The CCTV DVR recovery scanning process will determine if any fragments of the video data is recoverable. It uses forensic tools to document the procedure, authenticate the video, and capture video date and time.

FORENSIC RECOVERY SOFTWARE

We have the ability to scan and recover data  from a CCTV DVR, MDVR or NVR hard drive without administrative passwords. Popular makes/models of systems include Swann, Zmodo, Q-See, HIKvision, Samsung and more. In addition, we can also scan Ext 2/3/4, FAT, XFS, JFS and unpartitioned space and other files types. Moreover, our tools have access to hundreds of DVR video formats and proprietary coding necessary to recover lost video.

We have the ability to scan SATA, PATA and other hard disk connection types. We then communicate scanning results to the client in order to identify project scope and provide an accurate cost estimate. Size, accessibility, and the amount of recovered files necessary for analysis all factor into cost estimate.

Most fixed and mobile DVR-based surveillance systems employ proprietary computer operating systems and record digital video to proprietary formats. Evidence acquisition and rebuilding of proprietary video information requires specialized tools. For this reason, we have access to law enforcement recovery software databases that update daily based on proprietary DVR systems. 

DVR RECOVERY FOR LITIGATION

CCTV DVR Data Recovery

In summary, it is critical that litigators understand the importance of recovering CCTV DVR video evidence forensically. There are three main reasons:

 

  1. Firstly, when we recover evidence onsite, we document the process and video record it. This establishes an authentic chain of custody.
  2. Secondly, we take special precautions during the recovery process with the original recording.
  3. Thirdly, we recover the recordings to minimize any degradation in quality. For example, a multi-million dollar lawsuit may hinge on the analysis of a surveillance video evidence. Most importantly, it is best to trust the recovery of digital evidence to a forensically trained technician.

If you have a recording that you question or need help understanding, please contact us for a pro bono consultation.
