Recover CP Plus DVR FootageDeleted, Formatted or Missing Recordings
A CP Plus recorder shows a gap where the recording should be, or the whole disk reads as empty when you plug it into a computer. In most cases the video is still on the hard disk. This guide explains why Windows cannot see it, what to avoid and how to read the disk and get the footage back as normal video files.
Yes, deleted CP Plus DVR footage is usually recoverable until the recorder records over it. CP Plus recorders store video in their own special data format, which Windows cannot read, so the hard disk looks empty on a PC. Switch the recorder off, connect the disk to a computer and read it with a read-only tool that understands that format. Never format the disk, in the recorder or in Windows.
CP Plus is the biggest recorder brand in India, and its DVRs and NVRs are built on the Dahua platform. That matters for recovery, because it means the disk layout is a known one. The footage you cannot see in the recorder is normally still sitting on the platters, waiting for software that can read the layout directly.
Why does a CP Plus hard disk look empty on a PC?
Connect a disk from a CP Plus recorder to Windows and you get an unhelpful picture. Disk Management shows it as unallocated or not initialised, and Windows may offer to initialise it. Nothing is wrong with the disk. CP Plus recorders write video straight to the disk in what the manual calls a special data format, with no partition that Windows can open. The recordings are present as raw H.264 or H.265 video inside that layout. Windows has no idea how to map them, so it reports a blank disk.
The same thing happens with every recorder built on the Dahua platform, which is why the fix is the same across CP Plus models: read the disk with software that knows the layout, instead of letting Windows prepare it for ordinary files.
What should you do first when CP Plus footage is missing?
The first few minutes decide whether the recording comes back. Two settings and one habit do the damage.
Power the recorder down and refuse every format prompt. A CP Plus DVR set to overwrite keeps recording over the earliest files once the disk is full, so every hour it stays on can cost you the clip you want. When you later plug the disk into a PC and Windows offers to initialise or format it, close that box. The recorder's own Disk Manager format wipes the recordings too.
Worth knowing: CP Plus recorders can lock a recording so the overwrite cycle skips it, and the setup wizard has a delete expired files option that removes video after a set number of days. If someone turned that on, the footage may have aged out rather than been deleted by hand. Either way the recovery steps are the same.
How do you recover deleted footage from a CP Plus DVR?
The job runs on a Windows PC with the recorder switched off. No login, no CP Plus password and no working recorder are needed.
- Shut the recorder down. Unplug it the moment you notice the gap so the overwrite cycle stops.
- Remove the hard disk. Open the case, unplug the SATA data and power leads and lift the disk out. Note the bay it came from if the unit has more than one.
- Connect it to a PC read only. A SATA-to-USB dock is enough. If the footage may end up in a complaint or a court file, put a hardware write blocker between the disk and the PC.
- Scan the Dahua-style layout. Run DVRXaminer against the disk. It parses the CP Plus layout without writing to it, lists every channel and marks the recordings the recorder no longer shows, including deleted ones.
- Preview and export. Check the clip by date, time and channel, then export it as MP4 or AVI to a different disk, with the recorder's timestamp kept.

Which CP Plus recorders does this cover?
All the standard CP Plus recorder lines share the same storage approach, so the method applies across the range.
- CP-UVR models. The DVR and hybrid XVR units, sold under the Cosmic, Orange, Indigo and Vedaan series names. A 4 channel CP-UVR lists one SATA bay that takes a disk up to 6 TB.
- CP-UNR models. The network recorders. Depending on the model they carry one or two SATA bays, with limits of 8 TB or 20 TB per disk.
- Multi-disk units. Recorders with two bays may be set to mirror onto a redundant disk, so check both disks if the first reads as empty.
If you are not sure which line you have, the model number printed on the recorder matches the CP Plus user manual library, where each series has its own guide.
What decides how much comes back?
Recovery is not all or nothing. A handful of factors set the result.
- The overwrite setting. With overwrite on, the recorder records over the earliest video once the disk fills, so older clips go first. With it off, the recorder stops and nothing is lost to the loop.
- How long the recorder kept running. A busy 16 channel unit on a small disk cycles in days. A quiet 4 channel unit on a large disk can hold weeks.
- Whether the disk was formatted. A format in the recorder's Disk Manager or an initialise in Windows writes a fresh layout. Video can survive underneath it, but every new recording after that erases more.
- Disk health. Bad sectors cost you the clips that sat on them. A disk that clicks or drops out should be imaged once and worked on from the copy.
What if the CP Plus DVR is locked or dead?
Neither blocks a recovery, because the disk is read on a PC and the recorder's login never comes into it. A forgotten password is a separate problem, and our CP Plus password reset guide covers the official routes if you also need to get into the recorder itself. A recorder that reports no hard disk is covered in the CP Plus HDD not detected guide. A recorder that will not power on at all changes nothing: lift the disk out and read it, as the DVR data recovery page explains.
What can be recovered from a CP Plus disk?
Here is how the common situations compare, so you know what to expect before you start.
| Situation | Likely outcome |
|---|---|
| Clip deleted, overwrite on, recorder still running | Recoverable if the loop has not reached it yet, so act fast |
| Clip deleted, overwrite off | Recoverable, nothing new has been written |
| Disk formatted in the recorder's Disk Manager | Often recoverable, the video sits under the new layout |
| Disk initialised or formatted in Windows | Partly recoverable, depends on what Windows wrote |
| Recorder dead or will not boot | Recoverable, the disk is read on a PC |
| Password forgotten | Recoverable, the login is never used |
In short
- CP Plus recorders use their own special data format, so a PC reports the disk as empty when the video is still there.
- Shut the recorder down at once and refuse every format or initialise prompt.
- Read the disk on a PC in read only mode with a tool that understands the Dahua-style layout.
- A lost password or a dead recorder does not stop the recovery.
Common questions
Can deleted CP Plus DVR footage be recovered?
Usually yes, provided the recorder has not recorded over it. A deleted recording stays on the CP Plus hard disk until the overwrite cycle reaches that space. Shut the recorder down, connect the disk to a PC and read it read only with a tool that understands the CP Plus layout, then export the clips as normal video.
Why does my CP Plus hard disk show as unallocated on a PC?
CP Plus recorders write video in their own special data format with no Windows partition, so Disk Management reports the disk as unallocated or not initialised. The recordings are still there as raw H.264 or H.265 video. Do not initialise or format the disk, since that writes over the layout.
Do I need the CP Plus DVR password to recover footage?
No. The recovery reads the hard disk directly on a PC, so the recorder's login is never used. A forgotten or unknown password is not a barrier, and the same is true for a recorder that has failed or will not boot.
Will formatting the hard disk in the CP Plus DVR delete all recordings?
Yes, the recorder's Disk Manager format removes every recording from the recorder's point of view. The video often still sits underneath the new layout, so recovery is possible if nothing has been recorded since, but every new recording after the format erases more of it.
Which CP Plus models can footage be recovered from?
The CP-UVR DVR and XVR lines, which include the Cosmic, Orange, Indigo and Vedaan series, plus the CP-UNR network recorders. They all store video the same way, so the recovery method is the same. If a unit has two disk bays, check both disks.
How long does CP Plus keep footage before it is overwritten?
There is no fixed period. With overwrite on, the recorder records over the earliest video once the disk is full, so the window depends on disk size, number of channels and recording settings. A busy unit on a small disk can cycle in days. A locked recording is skipped by the overwrite cycle.
