DVR & NVR CCTV Data Recovery Services

Do You Need To Recover Lost DVR / NVR CCTV Images?

Data Clinic are the UK’s Number One company of choice recovering your DVR / NVR and CCTV data. If you have CCTV data recorded on a DVR or NVR system that you can no longer view, maybe because the system won’t play the footage back, or it’s been deleted, or the recorder and hard drives have been damaged: as long as the data still exists Data Clinic can retrieve it.

Retrieving CCTV DVR / NVR Images in Criminal Cases

CCTV has become a widespread weapon against crime; its very presence is a deterrent to people who are looking for opportunity, opportunity with a criminal motive. Often petty criminals will simply go elsewhere if they think there is video surveillance. That is not always the case of course and the provision of CCTV evidence in identifying a crime and finding a culprit has become an important tool for police and the judicial system.

Data Clinic can recover the information from CCTV DVRs and NVRs involved in criminal cases. Furthermore if the recorded incident is intended to be used in court, chain of custody procedures will need to be followed to ensure the retrieved video evidence is admissible. Please contact us for further details.

Incidents in the Workplace: Recovering CCTV DVR / NVR Images

CCTV is also increasingly used in the workplace to monitor safety and other related issues such as compliance to health and safety standards. If there’s been an accident or incident at work, the HSE (Health and Safety Executive) will usually request evidence of the incident on CCTV. Additionally they will want to examine the entire recorded footage to ensure safety compliance is being met.

Data Clinic are frequently asked to recover information from workplace CCTV DVR and NVR systems that show accidents and confirm compliance or non-compliance to safety standards.

If recorded incidents are to go to court, additional procedures have to be followed that ensure the evidence is admissible.

Recording CCTV to DVR / NVR Hard Disk

DVRs and NVRs operate by recording CCTV data on to hard disk and can be viewed with date and time details. Some monitoring is done on a much smaller scale; perhaps a PC which provides security for a room. Their encoding systems are Microsoft or Linux based

The technique of CCTV Data Recovery is the same as that used for all hard disk data retrieval. DVRs and NVRs have the same problems as any other device that uses a hard disk and our research and development department has ensured that we lead the field in data retrieval from hard disks in hardware and CCTV.

Securing CCTV Data – Beware of overwriting Nearly all CCTV systems record their data on a continuous loop. Once the end of the loop is reached, the system will start to overwrite the oldest data. The length of the loop is usually a figure in days. For example a CCTV system with a 21 day overwriting cycle will only store the last 21 days of data. Anything older that this date will have been overwritten by fresher data. So, if an incident occurred 24 days ago, this data will have already been overwritten and there is no chance of recovering it. Therefore it is important to secure data from a CCTV system before it is overwritten.

CCTV and DVR / NVR Problems

From time to time there are problems with either the DVR / NVR technology (often related to the hard disk drive) or the CCTV camera system and while it may not be a regular occurrence there is a demand for companies that can repair equipment and equally importantly retrieve lost data which might be useful in identifying someone who has committed a crime or finding a recorded workplace incident. Similarly, recorded CCTV video and audio can often be of poor quality such that words are difficult to identify and actions are difficult to see.
