Let’s get started!
What You’ll Need Before You Begin
Before diving into the setup, make sure you have the following:
- A Dahua DVR (Digital Video Recorder): This could be a standalone DVR or an NVR (Network Video Recorder) if you’re using IP cameras.
- An active internet connection: Your DVR must be connected to a router with internet access.
- An Ethernet cable: To connect the DVR to your router.
- A computer or smartphone: For initial setup and remote access.
- Your router’s login details: Usually found on a sticker on the router (username and password).
- A Dahua DDNS account (optional but recommended): Free and easy to set up.
Having these ready will save you time and frustration during the process.
Step 1: Connect Your Dahua DVR to the Network
The first step in learning how to online DVR Dahua is getting it connected to your local network.
Power On the DVR
Make sure your DVR is powered on and all cameras are connected. You should see the Dahua logo on the monitor or TV connected to the DVR.

Connect via Ethernet Cable
Use an Ethernet cable to connect the DVR’s LAN port to one of the LAN ports on your router. This gives the DVR access to your home or office network—and eventually, the internet.
Check the Network Status
On the DVR’s main menu, go to Settings > Network > TCP/IP. You should see an IP address assigned to the DVR (e.g., 192.168.1.108). This is its local IP address.
Tip: If no IP appears, your DVR might not be getting a connection. Check the cable, router, and power. Restart the DVR if needed.
Step 2: Assign a Static IP Address (Recommended)
By default, your DVR gets an IP address automatically from your router (via DHCP). But for remote access, it’s better to assign a static IP address—one that doesn’t change.
Why? Because if the IP changes, your remote access will break.
How to Set a Static IP on Dahua DVR
- Go to Settings > Network > TCP/IP.
- Change the IP mode from “DHCP” to “Manual”.
- Enter an IP address within your router’s range (e.g., 192.168.1.200).
- Set the subnet mask to 255.255.255.0 (common for most home networks).
- Enter your router’s IP as the gateway (usually 192.168.1.1).
- Set DNS servers (use 8.8.8.8 and 8.8.4.4 for Google DNS).
- Save and restart the DVR.
Example: If your router is 192.168.1.1, assign the DVR 192.168.1.200. Avoid using .1 or .255—they’re often reserved.
Step 3: Enable Port Forwarding on Your Router
Port forwarding tells your router to send incoming internet traffic to your DVR. Without it, you can’t access the DVR from outside your network.
Dahua DVRs use two main ports:
- Port 37777 (TCP): For video streaming and control.
- Port 37778 (UDP): For audio and faster data transfer.
How to Set Up Port Forwarding
- Log in to your router’s admin page (usually by typing 192.168.1.1 in a browser).
- Find the “Port Forwarding” or “Virtual Server” section (location varies by brand).
- Create a new rule:
- Service Name: Dahua_DVR
- External Port: 37777
- Internal Port: 37777
- Internal IP: Your DVR’s static IP (e.g., 192.168.1.200)
- Protocol: TCP
- Add a second rule for UDP:
- External Port: 37778
- Internal Port: 37778
- Internal IP: Same as above
- Protocol: UDP
- Save the settings.
Tip: Some routers let you forward both TCP and UDP in one rule. Check your router’s manual if unsure.
Step 4: Set Up DDNS (Dynamic DNS)
Your internet service provider (ISP) likely gives you a dynamic public IP address—one that changes periodically. That makes remote access hard because you won’t know the current IP.
DDNS solves this by linking a fixed web address (like mydahua.dahuaddns.com) to your changing IP.
Option 1: Use Dahua’s Free DDNS
- Go to Settings > Network > DDNS on your DVR.
- Enable DDNS.
- Select “Dahua” as the provider.
- Create a free account at www.dahuaddns.com (or use an existing one).
- Enter your DDNS username and password.
- Set a domain name (e.g., myhomecam.dahuaddns.com).
- Save and wait a few minutes for it to activate.
Option 2: Use a Third-Party DDNS (e.g., No-IP, DynDNS)
If you prefer another service, you can use No-IP or DynDNS. Just select the provider in the DDNS settings and enter your credentials.
Note: Some ISPs block common DDNS ports. If you have trouble, contact your ISP or try a different port.
Step 5: Access Your DVR Remotely
Now that your DVR is online, you can access it from anywhere using a phone, tablet, or computer.
Method 1: Using the Dahua Mobile App (DMSS)
The Dahua Mobile Surveillance System (DMSS) app is the easiest way to view your cameras on the go.
- Download “DMSS” from the App Store (iOS) or Google Play (Android).
- Open the app and tap “+” to add a device.
- Choose “DVR/NVR” > “Manual Add”.
- Enter:
- Device Name: My Home DVR
- IP/Domain: Your DDNS address (e.g., myhomecam.dahuaddns.com)
- Port: 37777
- Username: Your DVR login (default is usually “admin”)
- Password: Your DVR password
- Tap “Save” and wait for connection.
Tip: If it says “No Response,” double-check your DDNS, port forwarding, and internet connection.
Method 2: Using a Web Browser
- Open a browser on your computer or phone.
- Go to http://your-ddns-address:37777 (e.g., http://myhomecam.dahuaddns.com:37777).
- Log in with your DVR username and password.
- Install the Dahua Web Plugin if prompted (required for live view).
- You should now see your camera feeds.
Note: Some browsers (like Chrome) block plugins. Use Internet Explorer, Edge, or Firefox for best results.
Method 3: Using P2P (Plug-and-Play)
Many newer Dahua DVRs support P2P, which simplifies remote access without port forwarding.
- On the DVR, go to Settings > Network > P2P.
- Enable P2P and scan the QR code with the DMSS app.
- The app will automatically connect to your DVR.
This method is great for beginners—no router setup needed!
Step 6: Secure Your Dahua DVR
Now that your DVR is online, security is critical. Default settings are easy targets for hackers.
Change the Default Password
Immediately change the default admin password. Use a strong combination of letters, numbers, and symbols.
- Go to Settings > User Management.
- Select the “admin” user.
- Click “Modify” and enter a new password.
- Save and log out.
Disable Unused Features
Turn off Telnet, FTP, or HTTP if you don’t need them. These can be security risks.
Update Firmware Regularly
Outdated firmware can have vulnerabilities. Check for updates:
- Go to Settings > Maintenance > Upgrade.
- Download the latest firmware from Dahua’s official website.
- Upload and install it carefully (don’t power off during update).
Enable HTTPS (Optional)
For extra security, enable HTTPS encryption in the network settings. This protects data between your device and the DVR.
Troubleshooting Common Issues
Even with perfect setup, problems can happen. Here’s how to fix the most common ones.
Issue 1: “No Response” or “Offline” in the App
- Check your internet connection.
- Verify the DDNS is active (visit your DDNS URL in a browser).
- Confirm port forwarding is correct (use an online port checker).
- Restart the DVR and router.
Issue 2: Can’t Access via Web Browser
- Ensure the Web Plugin is installed.
- Try a different browser (IE or Firefox).
- Check if your firewall is blocking the connection.
Issue 3: Slow or Laggy Video
- Reduce the video resolution in the DVR settings.
- Use a wired connection instead of Wi-Fi.
- Limit the number of remote users.
Issue 4: DDNS Not Updating
- Log in to your DDNS account and check the status.
- Ensure the DVR has internet access.
- Manually update the IP in the DDNS settings.
Issue 5: Forgotten Password
- Use the Dahua password reset tool (available on their website).
- You’ll need the DVR’s serial number and a USB drive.
- Follow the instructions to generate a reset file.
Tips for a Smooth Experience
- Use a dedicated IP for your DVR: Avoid conflicts with other devices.
- Keep your router updated: Firmware updates improve security and performance.
- Test remote access regularly: Don’t wait for an emergency to find out it’s broken.
- Use strong Wi-Fi passwords: Prevent unauthorized network access.
- Label your cables: Makes troubleshooting easier.
