BDR / Evidence & investigations / Deleted or overwritten footage

Evidence & investigations · deleted CCTV footage

Deleted footage waits. Overwritten footage is gone.

Every deleted-footage case is a race against the recorder's own loop. Win it, and video comes back — often with its timestamps. Lose it, and no lab on earth can help, whatever their website says. This page is the honest version of both outcomes.

Index rebuild vs frame carving — the whole trade, honestly.

The proprietary indexRecorders keep their own map of what was filmed when, on which channel. Deletion usually removes map entries, not video.
Rebuild: the good outcomeParse the surviving index and footage returns organised — original dates, times and camera channels intact. Evidence-grade, straight away.
Carving: the determined outcomeWhere the index is gone, we scan the disk for raw H.264/H.265 video frames and reassemble them into playable files. The footage returns; its original time labels may not.
Overwritten: the honest limitLoop recording physically replaces old video with new. Once that's happened, the old bytes no longer exist — recovery ends where physics does.

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.

02

Freeze the evidence

Recording stops, the drive comes out, and a read-only image is taken. From this point the loop can't take anything else.

03

Rebuild the index

The recorder's proprietary structures are parsed on the image — where they survive, footage is restored with original timestamps and channel labels, ready for evidential use.

Carve the survivors

Where the index is damaged or gone, raw video frames are carved from the disk and reassembled into playable files — with honest labelling of what carries original time data and what doesn't.

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

  • The recorder's menu lies gently — 'deleted' means de-indexed, and de-indexed video is exactly what this bench recovers.
  • Carving finds video by its own grammar — H.264/H.265 frames announce themselves in the raw data, index or no index.
  • Timestamps are evidence too — which is why index-rebuild recoveries are worth more to a claim than carved ones, and why we're explicit about the difference.
  • Every honest quote starts with the loop maths — incident date versus loop length tells us, and you, whether hope is warranted before money moves.

The one-line physics: loop recording overwrites oldest footage first, continuously, without regard to what it shows — so the recoverability of any deleted clip is a function of exactly one thing: how much new video was recorded after it. Stopping the recorder is not a precaution; it is the recovery.

From the casebook.

A Lewes farm shop's deleted week, mostly rescued

A staff member cleared 'old clips' that included a theft. The recorder was stopped the same afternoon — the decision that saved the case. Index remnants restored four of the five deleted days with timestamps; the fifth came back by carving, playable but unlabelled.

Before it reaches us.

Do

  • Stop the recorder the moment you notice
  • Write down the incident date, time and cameras
  • Send the drive — or the whole unit, unopened
  • Tell us if the footage is for police or a claim

Don't

  • Keep recording to 'catch them coming back'
  • Let anyone re-format or factory-reset the box
  • Run undelete software against a DVR drive
  • Accept 'it's gone' from someone who hasn't imaged the disk

Asked in confidence, answered honestly.

Can deleted CCTV footage be recovered?

Often — deletion removes the recorder's index entries while the video itself stays on disk until the loop overwrites it. Stop the recorder and the odds are good.

Why can't overwritten footage be recovered?

Because the original bytes have been physically replaced by new video. There's no residue to read — claims otherwise are marketing, not engineering.

Will recovered footage keep its timestamps?

If the recorder's index survives, yes. If recovery has to fall back to carving raw frames, footage returns playable but may lose its original time and channel labels — we tell you which is which.

How long before the loop takes it?

Anywhere from days to a month-plus depending on cameras, resolution and disk size. Busy multi-camera systems loop fastest — assume urgency 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.
