Quick answer
Yes — deleted, overwritten-recently and failed-drive CCTV footage is often recoverable, including proprietary DVR/NVR formats from Hikvision, Dahua and others. But CCTV systems record on a loop and overwrite old footage continuously — so the single most important step is to power the recorder down immediately to preserve what's left. Then bring it to us for a free diagnosis.
Overview
Surveillance footage you need — recovered from the recorder.
When something happens on camera — a theft, an accident, a dispute — the footage on your DVR or NVR can be critical. But CCTV recorders don't store video like a normal computer: they use proprietary filesystems and record on a continuous loop, overwriting the oldest footage to make room for the new.
CBL recovers CCTV footage from failed recorder hard drives, deleted or corrupted recordings, and proprietary DVR/NVR formats across all major brands. We rebuild the video from the recorder's disks — including footage from a specific date, time or camera channel.
Power the recorder OFF right now
CCTV overwrites old footage on a loop. Every minute the system stays on, more of your footage is erased. Power it down, remove the hard drive if you can, and contact us urgently.
Time-critical
Why speed matters: the overwrite loop
Unlike deleted files on a computer — which can sit recoverable for a long time — CCTV footage is on a countdown. The recorder is actively overwriting the oldest recordings every second it runs. The sooner the system is powered off and brought to us, the more footage we can recover. If the incident is recent, act immediately.
1. Power off
Stop the recorder to halt overwriting.
2. Preserve the drive
Don't reformat, reset or "repair" the DVR.
3. Call us urgently
Bring the recorder or its hard drive in fast.
Same problem, different words
CCTV data recovery Singapore, DVR recovery, NVR data recovery — what people actually mean
People describe this problem in a dozen ways, and the words matter far less than which box is sitting in your riser cupboard.
"CCTV data recovery Singapore", "CCTV footage recovery", "surveillance video recovery"
All the same job: getting video off the storage inside a surveillance system. What genuinely varies is which storage — and that changes the method, the price and the odds.
DVR, NVR, or a camera's own SD card?
- DVR (digital video recorder). Analogue cameras run on coax back to one box, and that box encodes and stores the video on a single internal hard drive. DVR recovery therefore usually means one surveillance HDD, 1TB to 8TB, written in a proprietary layout.
- NVR (network video recorder). IP cameras stream over Ethernet to a recorder that may hold two, four or eight drives, sometimes striped or spanned together. NVR data recovery is closer to RAID recovery: we often have to work out the disk order and stripe geometry before a single frame appears.
- A standalone camera, doorbell or dashcam with its own card. No recorder involved at all — that is SD card recovery, with different failure modes and usually the lowest cost of the three.
Not sure which you have? Count the cables. Coax with screw-on BNC plugs into one box means DVR. Network cables into a PoE switch or into LAN ports on the recorder means NVR.
"CCTV repair" is the opposite of CCTV footage recovery
An installer repairs the system so it records again from today. We recover the footage already on the disk. Doing the first often destroys the second: reinitialising the recorder or fitting a fresh drive gets your cameras live again, but the incident you needed is written over. Get the footage out first, then let your installer restore the system.
"Hikvision recovery", "Dahua recovery"
The brand names describe the format, not the hardware. The disk inside is an ordinary SATA hard drive. What makes it unreadable on a PC is the manufacturer's own on-disk layout — so the brand matters a great deal for the software side of the job, and not at all for the mechanical side.
The one thing that actually changes the outcome
Not the phrase you search for, but whether the recorder is still powered on. A DVR never sits idle. Ten hours of deciding what to do can be ten hours of the incident gone.
Warning signs
What a failing recorder does before the footage goes
Surveillance recorders rarely die politely. They usually give weeks of small symptoms first, and each one points at a different fault.
- Gaps in the playback timeline. The search calendar shows recording on some days and blank stretches on others. Usually bad sectors — the drive skips the region it can no longer write to. This is the earliest warning and the most ignored.
- "No HDD" or "HDD error" on screen, with the buzzer beeping. The recorder can no longer see the disk, either because it has dropped off electrically or because its firmware area is damaged. Do not let the menu format it.
- Live view works, playback does not. The cameras and encoder are fine; the storage or the recording index is not.
- Export fails partway, or produces a 0KB file. The clips are being read from damaged areas, and every retry drags the heads back over the same weak sectors.
- Clicking or a rhythmic tick from inside the box. Mechanical head failure in the drive. Power the unit off — see hard drive clicking noise.
- The recorder reboots in a loop. Often a stalling drive holding up the boot sequence, sometimes a failing power supply. Both are hard on the disk.
Coverage
Brands & formats we recover
Every major recorder brand writes video in its own on-disk format. None of them use NTFS, exFAT or ext4 — which is why a DVR disk plugged into a Windows PC looks blank or unformatted. Recovering it means rebuilding that format, not simply undeleting files.

What the brand changes
- Hikvision. Video sits in large pre-allocated blocks with its own index near the front of the disk. Where that index is damaged, we identify the blocks and rebuild the timeline from the stream headers themselves.
- Dahua. A different block layout, with per-channel streams. Channel and timestamp mapping lives in structures we parse separately from the video data.
- Uniview, TVT and generic OEM boards. Common in budget installs here. Many share a handful of reference designs, so the format is often recognisable even when the badge on the box is not.
- Samsung / Hanwha and Bosch. Enterprise recorders with their own formats and, on larger systems, multi-disk volumes that must be reassembled before any footage can be read.
Surveillance-grade drives still fail
Most recorders ship with a WD Purple or Seagate SkyHawk — drives tuned for continuous sequential writing, with streaming commands that let a frame drop rather than stall the recording. That tuning helps. It does not make them immortal. They run 24/7 for years in a hot ceiling void or a dusty riser, often on unprotected mains, and in a multi-bay NVR they sit in each other's vibration. They reach us with bad sectors, seized motors and failed heads like any other hard drive.
Diagnosis
Why CCTV footage is lost
Failed surveillance hard drive
The DVR's HDD (often WD Purple) fails or clicks.
Deleted / overwritten footage
Loop recording or manual deletion after an incident.
Corrupt DVR filesystem
Power loss corrupts the proprietary format.
DVR reset / not recording
System reset or config loss stops recording.
Two of these hold still and two are races against the clock. A failed drive or a corrupted filesystem stops the system writing, so the footage stays where it is until we image the disk. Deleted footage and a recorder that has been reset are different: in both cases the unit is usually still running, and every new frame lands on top of the old one.
How it works
Our CCTV recovery process
Step 1: Free diagnosis (urgent)
Bring in the recorder or its hard drive. We assess the fault and confirm what footage is recoverable — with priority for time-critical incidents.
Step 2: Image the drive
We clone the surveillance drive first — repairing it in the cleanroom if it has physically failed — so the original is never risked.
Step 3: Rebuild the proprietary format
We reconstruct the DVR/NVR's proprietary filesystem and reassemble the fragmented H.264/H.265 video streams.
Step 4: Extract footage
We extract the requested cameras, dates and times as playable video, and provide a list to verify.
Step 5: Secure return
Footage returned confidentially on fresh media.

Avoid permanent loss
DIY mistakes that destroy CCTV footage
Surveillance systems invite tinkering — the recorder has a menu, the drive is four screws away. These are the mistakes we see most often, and what each does to your footage.
- Leaving the recorder running while you decide. The single biggest destroyer of evidence. Loop recording does not pause because something important happened.
- Plugging the DVR drive into a Windows PC "just to look". Windows cannot read the proprietary format, so it reports the disk as uninitialised and offers to fix it. Accepting writes a new partition table over the recorder's index. Even if you decline, Windows writes volume metadata to disks it mounts.
- Formatting from the recorder's own menu. An "HDD error" prompt tempts you into a format. That clears the index and restarts recording at the beginning of the disk.
- Running consumer recovery software over it. Those tools hunt for NTFS, FAT and known file signatures. A surveillance disk has none of them, so you get nothing, or a heap of unplayable fragments.
- Letting someone reconnect the old drive to "test" it. Powering a failing drive up repeatedly for another look is how a recoverable head fault becomes scored platters.
Never let a recorder format or initialise its own disk
The "HDD error — format now?" prompt on a DVR menu is the most common way surveillance footage is lost for good. Power the unit off instead and talk to us first.
DIY software has a place on a healthy computer disk with a minor deletion and a backup elsewhere. It has almost none on a surveillance drive — see DIY vs professional recovery →

Exporting footage an insurer, a landlord or the police can actually use
Recovered footage only helps if the other side can open it. Where we can, we return two versions: the native clips in the recorder's own format, which keep the embedded channel and time data intact, and a converted copy in a standard player format so nobody needs the manufacturer's software to watch it. We also extract the continuous span either side of the incident rather than one clipped moment — context is usually what settles a claim.
Timestamps matter more than people expect
Recorder clocks drift, and many are never reset after a power cut; few small installs are synchronised to a time server at all. If the DVR clock was forty minutes slow, the clip labelled 3:10pm is really 3:50pm — and anyone comparing it against a receipt or a door log will notice. We give you the time the recorder wrote, not a time we invent, and we flag it when the clock looks wrong so you can state the offset yourself.
Tell us the incident window
Give us the date, the approximate time and which camera. That lets us prioritise the right region of the disk and check first whether the footage still exists — before you commit to anything.

The honest comparison
CBL vs a CCTV installer vs DIY software
Your installer is the right person to get the cameras recording again. They are usually not equipped to get lost footage back, and most of them will say so.

Answers
CCTV recovery FAQ
Often yes, if the recorder is powered off quickly. CCTV records on a loop and overwrites old footage, so the sooner you stop it, the more we can recover. A free diagnosis confirms your case.
It depends on the number of cameras, resolution and drive size — from a few days to a few weeks. Because it's continuous, power the recorder off immediately to preserve what's left.
Yes — surveillance drives (often WD Purple) are hard drives; we cleanroom-repair and image them, then rebuild the footage.
Yes — we reconstruct the proprietary DVR/NVR filesystems used by Hikvision, Dahua and other major brands.
Yes — we extract footage by date, time and camera channel where it hasn't been overwritten.
We handle footage for insurance claims and legal matters with confidentiality and care. We can discuss your specific evidentiary needs.
Indicatively $180–$650 for logical/deleted, $400–$1,800 for a failed drive, and from $1,200 for NVR RAID. Your free diagnosis gives an exact fixed quote.
Please don't. No Windows tool can interpret a DVR's on-disk layout, so the drive presents as empty and Windows prompts you to initialise it — accept, and a new partition table lands on top of the recorder's index. Simply mounting it writes metadata too, and on a failing drive that extra activity costs you sectors. Bring it to us untouched instead.
Usually yes, and we would rather say so than take your money. Loop recording is a genuine overwrite: new video is physically written on top of old video. Occasionally fragments survive in a region the recorder skipped, and we check for that during the free diagnosis. But we will not promise footage the disk no longer holds.
Not necessarily. Many NVRs do not use RAID at all: they write each camera to a particular disk, or span a volume across several, so one failed disk may cost you only some channels. Where an array is used, we image every member and rebuild the volume from the copies. Bring all the drives, labelled with the bay each came from.
Bring the whole unit if you can. The model and firmware tell us which format to expect. If the recorder is rack-mounted or still in service, bring the drives plus a photo of the model label.
They are built for the duty — continuous sequential writes, streaming commands, tolerance for multi-bay vibration — so they generally outlast a desktop drive in a recorder. They still fail. Heat in a ceiling void, years of uninterrupted running and unprotected mains finish them off like anything else.
