CCTV footage is often needed at exactly the worst moment — after a break-in, an accident or an incident — and it comes with a hidden clock: DVRs and NVRs record in a continuous loop, so the footage you need is steadily being written over by new recording. If a system has failed, or you need footage that may be about to disappear, the priority is to preserve the drive now and recover it properly. We recover CCTV footage from DVRs and NVRs for people and businesses across the UK.
Footage of an incident can be overwritten within days as the loop continues. Preserve the drive now.
Recovering CCTV isn’t like recovering an ordinary drive, for two reasons. First, DVRs and NVRs don’t store footage as normal video files on a standard file system — each manufacturer uses its own proprietary format and file system, designed for continuous recording rather than for a computer to read. Pull the drive out, plug it into a PC, and Windows sees nothing usable. Recovering the footage means understanding and decoding that specific system, then exporting the video into a format you can actually play.
Second, and more urgently, CCTV systems record in a loop: once the drive is full, the oldest footage is continuously overwritten by the newest. That gives most systems only days or weeks of history — so footage of an incident is on a countdown from the moment it’s recorded. The drive inside the box is a standard hard drive, and can fail like any other, but the loop is what makes CCTV recovery time-critical in a way little else is.
Overwritten by the loop. The most common and most time-sensitive — the footage you need has been, or is about to be, recorded over as the system continues. The only defence is to preserve the drive quickly.
The DVR / NVR won’t boot, or the drive has failed. The recorder’s hard drive fails like any other — mechanically, electronically, or with a corrupt file system — and the system won’t play back or record.
Footage deleted or the drive reformatted. Recordings deleted, or the drive wiped or reset — usually still recoverable if the drive hasn’t been recording over them since.
System corruption after a power cut. A power interruption corrupts the recording structure, and the DVR can no longer read its own footage.
A failing surveillance drive. Surveillance drives run continuously for years and wear out — a tired drive may hold footage that a standard read can’t reach but a proper drive recovery can.
If you need footage of a specific incident, the clock is running, so act deliberately. Don’t leave the DVR recording — every hour it keeps going, more of the loop is overwritten, potentially including what you need. The safest move is to stop the system and preserve the drive: power the recorder down, or take the hard drive out and set it aside, so nothing more is written. Don’t reformat or ‘repair’ the DVR to get it working again if that risks recording over the footage. And don’t reset the system to factory settings. If the footage may be needed for police or an insurance claim, preserving the drive promptly is the single most important thing you can do.
We take the hard drive from the DVR or NVR and image it read-only — giving it clean bench or board-level attention first if the drive itself has failed. From the image we decode the manufacturer’s proprietary file system and video format, reconstruct the recordings, and locate footage by date, time and camera channel so we can find the specific period you need. We then export the footage into a standard, playable video format you can view, keep and share — and provide it in a form suitable for police or insurers where required. Everything is done from the image, so the original drive and its remaining footage are never altered.
It starts with a free diagnostic: we assess the drive and the system, establish what footage can be recovered from the period you need, and give you a fixed written quote before any chargeable work. Because CCTV is often time-critical, a priority service is available (see emergency recovery). On most jobs it’s no fix, no fee, and pricing is per case. It’s all done by post, so you don’t need to be nearby — send the drive or the whole recorder in from anywhere in the UK or Ireland.
Often, yes — but act quickly, because CCTV records in a loop and overwrites old footage with new. The moment you know you need a particular period, stop the system and preserve the drive: power the recorder down or take the hard drive out, so nothing more is recorded over it. The sooner it’s preserved, the better the chance the footage is still there for us to recover and export.
It depends how much has been recorded since. Once the loop has written over a period, that footage is genuinely gone — but if only part of it has been overwritten, or the system stopped before reaching it, we can often still recover what remains. It’s always worth assessing, and the key lesson is to preserve the drive as early as possible next time to stop the overwriting.
Usually, yes. A DVR that won’t start often has a failed or corrupt hard drive — the drive fails like any other, but the footage on it is typically recoverable. We image the drive (repairing it first if it’s physically failed), decode the manufacturer’s format, and export the footage. Take the drive out or send the whole recorder and we’ll recover what’s on it.
The vast majority. DVRs and NVRs use a range of proprietary formats — from Hikvision, Dahua, Swann, HKVision-based systems and many others — and we decode the manufacturer’s file system and video format to reconstruct the footage. If you can tell us the make and model, we’ll confirm, but in practice we handle almost all common systems.
Yes. Recovered CCTV is exported into a standard, playable video format you can view on a normal computer, keep and share — not the DVR’s proprietary format that only its own software can open. Where the footage is needed for police or an insurance claim, we can provide it in a suitable form, organised by date, time and camera.
No. Our lab is in Belfast, but CCTV recovery is done by post, so we work with people and businesses right across the UK and Ireland. Send the drive or the whole recorder in with insured, tracked delivery — and because footage is time-sensitive, a priority service is available.
Stop the recorder or take the hard drive out to stop the overwriting, and get in touch. We’ll assess what footage can be recovered for free, give you a fixed quote before any chargeable work, and export it to playable video — with a priority service when it’s time-critical.
