DVR / CCTV Recovery
Surveillance systems record continuously onto embedded DVR or NVR storage using proprietary file systems and video containers that standard recovery software cannot read — a single incident often means the footage you need is on a drive that has just failed.
Understanding the Problem
Surveillance systems record continuously onto embedded DVR or NVR storage using proprietary file systems and video containers that standard recovery software cannot read — a single incident often means the footage you need is on a drive that has just failed.
We recover from DVR and NVR hard disks removed from failed recorders, corrupted proprietary file systems, and cases where footage was accidentally overwritten or the recorder's firmware became unstable.
Recovered footage is exported into standard playable video formats along with timestamp data, so it remains usable as evidence for insurance, legal, or internal investigation purposes.
Common Failure Symptoms
- DVR/NVR fails to boot or gets stuck on a manufacturer splash screen
- Recorded footage is missing for a specific date/time range
- Playback shows garbled video, freezing, or audio-only segments
- Internal hard disk removed from the recorder is not recognized by a PC
- "Disk Error" or "Format Required" messages on the recorder's display
- Footage needed for evidence but the recorder or drive has since failed

Our Recovery Process
A disciplined, four-stage workflow protects your data at every step — from intake to secure return.
Diagnosis
We inspect the device, identify the failure type (mechanical, logical, firmware, or physical) and give you a transparent quote before any work begins.
Evaluation
Our engineers run a deeper imaging and diagnostic pass in a controlled environment to map exactly what is recoverable and what approach is safest.
Recovery
Using cleanroom hardware, donor parts, and tools like PC-3000, we image the media sector-by-sector and reconstruct your file system and files.
Return
Recovered data is verified, indexed, and delivered on encrypted media or secure transfer — with your original device returned or securely disposed of.
