Evidence & investigations · CCTV & DVR recovery

The recorder is still recording. That’s the problem.

CCTV systems overwrite their oldest footage by design — a loop that doesn't pause because something important happened. The single most useful thing anyone can do after an incident is stop the recorder. Everything we do after that works better for it.

No fix, no fee on recovery jobs Evidence-grade handling Act fast — loops overwrite

The recorders on this bench.

Hikvision & HiLookThe UK's most common systems — with a proprietary index that, when it survives, hands footage back with dates and channels intact.
DahuaThe other giant, with its own on-disk metadata scheme. Same story: parse the index if it lives, carve the video if it doesn't.
Swann · Annke · Reolink · UniviewThe consumer and small-business tier — different badges, familiar internals, all recoverable at the disk level.
The unbranded boxesWhite-label recorders from long-gone installers. No documentation, no support — but the video on the disk obeys the same physics.

01

Booked in, diagnosed free Free

Your device is logged with its own case reference the moment it arrives. An engineer assesses the fault, confirms what's actually recoverable, and you get a fixed price in writing — no diagnosis fee, no obligation, and no paid work until you say go.

Stop the loop

First instruction on every call: stop the recorder, or at least pull its drive. Loop recording is overwriting the very footage you need — right now, while you read this.

Recorder stoppedOverwrite halted
03

Image the DVR drive

The drive comes out and is imaged read-only — the recorder itself isn't needed, and a dead one isn't an obstacle. All work happens on the copy.

04

Rebuild the index — or carve the frames

If the recorder's proprietary index survives, footage is rebuilt with dates and channels. If it doesn't, H.264/H.265 frames are carved from the disk and reassembled into playable files.

Verified, returned, signed off

Before you pay the recovery fee you approve a full listing of what came back. Your data returns on new media with free return postage, and the case only closes once you've confirmed everything opens on your side.

What the lab holds to

  • DVRs don't use normal file systems — Hikvision, Dahua and the rest write their own on-disk structures, which is why 'undelete' software comes back empty.
  • The index is the luxury — parse it and footage returns with timestamps and channels; lose it and carving recovers the video without its labels.
  • The loop doesn't respect incidents — recorders overwrite oldest-first regardless of what the footage shows.
  • Retention settings lie optimistically — a '30-day' system with more cameras than it was specced for can loop in a week.

On the '30 days' everyone quotes: there is no legal CCTV retention period in the UK — around 31 days is an industry convention shaped by data-protection's storage-limitation principle, and real systems often loop far sooner than their settings claim. The safe assumption after any incident is that the clock is already running.

A Brighton shop break-in, and a DVR that kept on taping

By the time the insurer asked for footage, the recorder had been looping for nine days. The drive was imaged, the index parsed, and the incident window recovered from sectors the loop hadn't yet reached — exported twice, once for people and once for the claim.

Before it reaches us.

Do

  • Stop the recorder — or pull its drive — immediately
  • Note the date, time and camera positions that matter
  • Send the drive, or the whole recorder if easier
  • Say who needs the footage: police, insurer, or you

Don't

  • Leave it recording 'in case something else happens'
  • Delete other clips to make space
  • Let the installer reset or update the recorder
  • Export-and-hope with the recorder's broken USB export

Asked in confidence, answered honestly.

Can deleted CCTV footage be recovered?

Often, yes — if the recorder was stopped before the loop overwrote it. Deleting removes index entries; the video itself survives until new recording lands on top of it.

Can overwritten CCTV footage be recovered?

No — genuinely overwritten video has been physically replaced by new video, and no lab can undo that. It's why stopping the recorder is the whole ballgame.

My DVR is dead — is the footage gone?

Usually not. Footage lives on the hard drive inside; we remove it, image it, and recover from the image. The recorder is just the box it lived in.

How long do I have?

It depends on disk size, camera count and quality settings — busy systems can loop in days. Treat every footage job as urgent until the recorder is stopped.

Evidence doesn't wait. Neither should you.

Loops overwrite, artefacts age, deadlines pass. Open a case first — the scoping conversation is free and confidential either way.
