Step-by-Step Guide to How to Connect Dahua NVR to NAS in 2026 A Complete Guide

Step 1: Set Up Your NAS Share Folder

The first step in how to connect Dahua NVR to NAS in 2026 is preparing your NAS. You need a dedicated folder where the NVR can save video backups.

Log into your NAS via its web interface (e.g., Synology DSM or QTS). Navigate to Control Panel > Shared Folders > Create. Name the folder something clear, like dahua_backups. Avoid spaces or special characters.

Next, go to File Services > SMB/AFP/NFS and ensure SMB (Windows Sharing) is enabled. SMB is the most compatible protocol for Dahua NVRs.

Now, set permissions. Click on the share folder, go to Edit > Permissions, and add a user (or guest access) with Read/Write rights. For security, avoid using admin accounts. Instead, create a limited-access user like surveillance_user.

Pro Tip: Test the share folder from another computer on the same network. Try mapping it as a network drive. If it works, your NAS is ready for the NVR.

Step 2: Assign Static IP Addresses to NVR and NAS

Dynamic IPs can change, breaking the connection between your NVR and NAS. To prevent this, assign static IP addresses to both devices.

For the NAS: In its control panel, go to Network > Network Interface. Edit the LAN interface and set a static IP (e.g., 192.168.1.100). Use a subnet mask like 255.255.255.0 and enter your router’s IP as the gateway.

For the Dahua NVR: Access the NVR’s local menu (via HDMI or remote desktop). Go to System > Network > TCP/IP. Switch from DHCP to static mode. Assign an IP close to the NAS (e.g., 192.168.1.101) with the same subnet and gateway.

Why does this matter? Static IPs ensure the NVR always knows where to find the NAS. This is a crucial step in how to connect Dahua NVR to NAS in 2026 without future disconnections.

Warning: Don’t assign IPs that conflict with your router’s DHCP range. Check your router’s settings first to avoid overlap (e.g., if DHCP starts at 192.168.1.10, use 192.168.1.100–150 for static devices).

Step 3: Enable Network Backup on the Dahua NVR

Now, configure the NVR to recognize and use the NAS. This is where the magic happens in your how to connect Dahua NVR to NAS in 2026 journey.

On the NVR, go to Storage > Storage Management > Network Disk. Click Add to create a new network storage entry.

You’ll see fields to fill:

• Server Address: Enter the NAS’s static IP (e.g., 192.168.1.100)
• Port: Usually 445 (default for SMB)
• Share Folder: Type the exact name of your NAS folder (e.g., dahua_backups)
• Username/Password: Enter the credentials you set for the NAS user
• Disk Letter: Choose a drive letter (e.g., Z:)

Click Test. If successful, you’ll see “Connection successful.” If not, double-check IP, folder name, and credentials.

Once connected, the NAS will appear as a “Network Disk” in the NVR’s storage list. You can now assign it for recordings or manual backups.

Step 4: Configure Recording Settings to Use NAS

With the network disk added, tell the NVR to use it for video storage.

Go to Storage > Schedule Settings > Record Schedule. Select the camera(s) you want to back up to NAS.

In the schedule grid, click on a time block and choose Continuous, Motion, or Event recording. Then, under Storage Path, select the NAS disk (e.g., Z:).

You can also set up Manual Recording to save clips directly to NAS. Go to Playback > Manual Record, and ensure the target path is the network disk.

For redundancy, some users set dual recording: local NVR drive + NAS. This way, if the NAS goes offline, footage still saves locally.

Pro Tip: Use Event Recording on NAS for motion-triggered clips. This saves bandwidth and storage space while keeping critical footage safe.

Step 5: Set Up Automatic Backups (Optional but Recommended)

Beyond live recording, you can schedule automatic backups of existing footage to NAS. This is perfect for long-term archiving.

Go to Storage > Backup > Backup Settings. Click Add to create a new backup task.

Configure:

• Backup Device: Select the NAS network disk
• Time Range: Choose days/hours (e.g., last 7 days)
• Cameras: Pick which ones to back up
• Schedule: Set daily or weekly (e.g., every Sunday at 2 AM)
• File Format: Choose DAV (Dahua format) or MP4 (universal)

Click Save. The NVR will now automatically copy footage to your NAS on the schedule.

This feature is a game-changer for compliance, audits, or insurance claims. It’s a key part of how to connect Dahua NVR to NAS in 2026 for full data protection.

Step 6: Test and Monitor the Connection

After setup, test the system thoroughly. Don’t assume it works until you verify.

Trigger a motion event or start a manual recording. Wait a few minutes, then check the NAS folder. You should see new files appearing.

Use the NVR’s Playback function and select the NAS disk. Can you view the footage? If yes, the connection is live.

Monitor for a few days. Check logs in Maintenance > Log > Backup Log for errors like “Connection failed” or “Access denied.”

If issues arise, restart both devices and re-test. Most problems stem from incorrect IPs, firewall blocks, or permission issues.

Pro Tip: Enable email alerts on the NVR. Set it to notify you if the NAS connection drops. Go to System > Event > Alarm Output and configure email notifications.

Step 7: Secure and Optimize the Setup

Security is critical. An open NAS share can be hacked. Protect your how to connect Dahua NVR to NAS in 2026 setup.

On the NAS:

• Disable guest access if not needed
• Use strong passwords for all users
• Enable firewall rules to allow only the NVR’s IP
• Update NAS firmware regularly

On the NVR:

• Change default admin password
• Disable UPnP if unused
• Enable HTTPS for remote access

For performance, consider:

• Using a dedicated VLAN for surveillance devices
• Upgrading to 10GbE if handling 4K+ cameras
• Scheduling backups during off-peak hours

A well-optimized system runs smoother and lasts longer.

Pro Tips & Common Mistakes to Avoid

Even with perfect setup, small oversights can cause big problems. Here are expert tips and pitfalls to avoid in how to connect Dahua NVR to NAS in 2026.

✅ Pro Tips

• Use SMBv2 or higher: Older SMB versions (v1) are slow and insecure. Enable SMBv2/v3 in NAS settings.
• Label your NAS shares clearly: Avoid confusion with names like “Camera1_Backup” instead of “Folder1.”
• Test with one camera first: Before scaling to 8 or 16 cameras, validate the setup with a single stream.
• Monitor disk space: NAS drives fill up fast. Set alerts in your NAS dashboard when usage hits 80%.
• Use RAID on NAS: RAID 1 or 5 protects against drive failure. Don’t rely on a single disk.

⚠️ Common Mistakes

• Using dynamic IPs: If your NAS reboots and gets a new IP, the NVR won’t find it. Always use static IPs.
• Incorrect folder path: Typing dahua_backup instead of dahua_backups breaks the link. Copy-paste the exact name.
• Ignoring firewall rules: Some routers block SMB ports by default. Ensure port 445 is open.
• Skipping permission tests: Always verify you can read/write to the NAS folder from another device first.
• Overloading the network: Streaming 10+ 4K cameras to NAS can saturate a 100Mbps link. Use gigabit switches and cables.

Warning: Never expose your NAS to the public internet without a reverse proxy or VPN. Direct access is a major security risk.

By avoiding these errors, your how to connect Dahua NVR to NAS in 2026 project will run smoothly and securely.
