In many instances where footage is deleted, overwritten, or when a recorder drive fails, there still exist recoverable recordings that are required for an incident, insurance claim, police etc. We have knowledge of the proprietary formats used by DVR/NVR systems to rebuild the video files, which we then export as standard timestamped files.
DVR/NVR systems record in a loop (writing over oldest footage as new footage arrives), so every hour a system is running the footage required for an investigation or court case is that much closer to being lost forever. The longer the recorder runs before it is powered off/drive removed, the less chance there exists of recovering any useable footage, so do not keep recording or reset the system. And once a drive has failed, do not continue to try recovering it; bring the drive to us as soon as possible.
This is where we most often recover the deleted/damaged/failed footage; whether footage was deleted, recorded over or the recorder’s hard drive has failed, footage is often still present on disk waiting to be extracted.
We have experience recovering video footage from virtually all types of Digital Video Recorders (DVRs), Network Video Recorders (NVRs) and security camera systems (whatever proprietary format they use). As long as the unit was recording at the time of the incident, we can almost certainly recover that footage.
Analogue and IP CCTV · DVRs and NVRs · single and multi-drive systems · RAID NVRs · standalone and dashboard cameras · SD and microSD cards.
Recovering footage from Closed Circuit Television (CCTV) systems requires that we understand the proprietary format used by the DVR/NVR/security camera system and never write to its drive. In addition to creating a copy of the drive, we carve the recovered video back into standard files based on camera and time.
Provide us with information about the type of DVR/NVR/security camera system you are using, which camera(s) produced the desired footage and what date and time you would like to view.
If the DVR/NVR/security camera system is currently operational, our top priority is to create a complete image of the drive before the record loop causes additional damage to the footage that you want to retrieve.
We perform a sector-by-sector image of the DVR/NVR/security camera system’s hard drive. Even if the hard drive is in failure mode, we do NOT write to this original drive; rather, we work solely on this image copy.
We break down the manufacturers’ (Hikvision, Dahua and the rest) proprietary file systems to obtain the videos.
The H.264/H.265 video streams will be rebuilt (for example) and we will then take the required channels and time frames out of them.
The extracted footage will be exported as standard, with timestamp, MP4 or AVI files and it will be confirmed that the event has been recorded.
After being transferred securely or sent back to you on new media, your recovered footage can now be used in an investigation, or given to your insurance company or the police.
We can recover footage from DVRs, NVRs, RAID recorders, security cameras and SD cards: this will involve us taking a read-only copy of the recorder’s data; decoding the recorder’s format and then exporting your recordings as standard files.
Tell us what happened and we will get back to you, usually within one working day.
We will be in touch shortly. For anything urgent, call 0117 332 1137.
There are no hidden costs and/or pressures, simply a complimentary examination and a detailed written quotation prior to commencing any repair.
Recent examples of CCTV/DVR/NVR recoveries; names removed and footage provided.
We shut off power to the DVR; took an image of the drive and cut out the H.265 streams covering the date of the incident in question. The complete incident had been recovered.
Rebuilt the RAID from copies of each of the four drives; decoded the recording and exported the specific dates that were requested by the customer to pass on to their insurer.
We captured an image of the card and parsed the recording based on date/time stamps, allowing us to recover the video that the owner required.

These are the main questions about CCTV footage recovery we receive regarding DVR and NVR systems.
In many cases. Footage deleted from a DVR/NVR typically has enough time remaining before the system begins writing over the oldest footage again. Therefore, if possible, power off your system immediately after an incident and send it to our office. Once received, we will image the drive and rebuild the recordings into standard video formats.
Not necessarily. DVRs have an overwrite feature which deletes older recordings (first-in-first-out), but many of those files can be recovered, especially if you’ve cut a recording short. Please shut down the recorder right away and bring it to our office.
Due to how DVR and NVR manufacturers have implemented their proprietary file system, computers are unable to recognise these drives as having content. This means that even though the footage exists, a typical computer would see this as an “empty” or “unformatted” drive. We understand the specifics of each brand’s proprietary format. With knowledge of each brand’s specific format, we are able to parse through and extract the footage and present it in a standard Windows/Mac compatible video file format.
Yes. Regardless of whether or not a recorder boots up properly or if a disk is either clicking or unreadable due to failure, we always image the drive(s) in a read only mode and subsequently parse the format and carve out the desired footage. Each situation requires unique solutions based upon individual circumstances.
Yes. Upon receiving your request for video recovery, please provide us with information regarding which recorder was used during the incident, which camera channel the relevant footage originated from, and what time frame the incident occurred in. We will target the relevant recordings within this timeframe and export them in their original date/timestamp format.
Yes. We specialise in multi-disk NVR systems as well as RAID configured recorders. Whether it is a single disk or multiple disks, we will image each drive individually, rebuild the arrays, then recover and export the relevant footage as described above.
The recovered video is always in a format of standard, timestamped MP4 or AVI files. This allows you to view them on any video player, save them, or pass them along to an insurance company or law enforcement agency as needed, independent of using the recorder’s own proprietary software.
Absolutely. We can successfully recover corrupted, formatted or unreadable data from both SD and microSD memory cards used in IP and standalone cameras. We simply “image” the entire card, then extract all of the recorded video segments (clips) back out of the image file.
Recovering footage costs £400 + VAT per single unit (one device), while recovering data from camera SD cards is significantly less: £300 + VAT. If you have a failed drive or multiple drives in a RAID configuration, the cost will be higher; please contact us with regard to a custom quotation.
You should take the hard drive or memory card out of the recording system and either post this item fully insured, or bring it into our Bristol office Monday to Friday, 9am to 5:30pm. We can also accept posted media at our offices. Please include your contact information and let us know the date and time you need so we can book it in.
All free diagnostics; footage extraction based on date, time and camera, as well as recovery from DVRs, NVRs and SD cards, including those that fail, with footage extracted from the original file(s) and delivered in a standard video format. Contact us today.
