Add a NAS to a Uniview NVR (Network Disk over NFS)
A Uniview NVR can record to a NAS over the network instead of (or alongside) its own drives — effectively a network hard disk for the recorder. The recorder side is the same on every brand; what differs is how each NAS exposes the share.
How it works on the recorder
Network disks are managed from the NVR's HDD management screen, where you can add, edit, delete and format them just like a local disk.
Add the network disk
Open HDD management on the recorder and add a network disk.
Set usage, type, IP and directory
The editable fields are usage, type, IP address and directory. Usage is either Recording/Snapshot or Backup.
Backup usage
Set to Backup, the disk's properties cannot be changed afterwards.
Recording / Snapshot usage
Set to Recording or Snapshot, the properties remain editable.
- NAS type only. The recorder supports network disks of type NAS — not IPSAN and not eSATA, even though those appear in the type list.
- The share must be NFS with read/write. Authentication is by root user and IP address rather than a username and password, so the NAS has to grant the recorder's IP write access over NFS. An SMB-only share will not mount.
NAS models Uniview has tested
| Vendor | Model | Status |
|---|---|---|
| Synology | DS216j | Supported |
| NETGEAR | RND-28 (ReadyNAS) | Supported |
| WD | WCC4E3DCFPJ5 (MyCloud) | Supported |
| QNAP | TS-251+ | Supported |
Other NAS units that can serve an NFS share with read/write access generally work too — these are simply the four Uniview validated.
Setting up the share on your NAS
Pick your brand. Every one comes down to the same three things: create a shared folder, enable NFS on it, and grant read/write.
Sign in to DSM
Open the Synology web interface in a browser and log in as an administrator.
File Station → Create → New Shared Folder
Create the folder the recorder will write to.
Name the folder
Give it a name you will recognise on the NVR, e.g. NVR_NAS.
Set permissions to read / write
The recorder must be able to write, not just read.
Configure NFS permissions
Add an NFS rule for the recorder. This is the part people miss — SMB alone will not work.
Read the mount path, then add it on the NVR
Right-click the folder → Properties to see the exact directory path. Enter that path on the recorder.
Create a shared folder
On the ReadyNAS admin page, create a share — the guide uses NVR_NAS.
Open the share's settings
Select the new share to edit its protocol and access settings.
Enable the NFS protocol
Turn NFS on for this share and allow write access.
Add the NAS disk on the NVR
Enter the NAS IP and directory on the recorder.
Open the MyCloud dashboard
Log in to the WD MyCloud web dashboard.
Create a share
Add a new share for the recorder to use.
Enable NFS and the write switch
Both are required — NFS on, and write access enabled.
Check the share settings
Confirm the share name and path before leaving the dashboard.
Add it on the NVR
Enter the NAS IP and directory on the recorder.
Open Control Panel
From the QTS desktop, open Control Panel (Panel de control).
Open System
System (Sistema).
Privilege → Shared Folders
Privilegio → Carpetas compartidas, then choose to create a folder.
Create the shared folder
Enter a name and confirm (Crear).
Open the folder's permission icon
Select the permissions action on the new folder's row.
Choose NFS host access
Acceso al host NFS — this is the NFS permission page.
Set access right to read / write
Derecho de acceso → lectura y escritura, then Aplicar.
Connect the NAS to the NVR
Enter the NAS IP and directory on the recorder.
