Before diving into the setup, make sure you have the following:
- A Dahua DVR with network capability: Most Dahua DVRs (like the XVR5104HS, NVR5216-16P, or older models like the DHI-XVR5104C) have an Ethernet port. Check the back of your unit to confirm.
- An Ethernet cable (Cat5e or Cat6): This connects your DVR to your router. A wired connection is strongly recommended over Wi-Fi for stability.
- A router with internet access: Your DVR needs to be on the same local network as your router to communicate with the internet.
- A computer or smartphone: For initial setup and remote access.
- Your Dahua DVR’s default login credentials: Usually admin / admin or admin / 123456. Check your manual if unsure.
- The Dahua mobile app (DMSS): Download it from the Apple App Store or Google Play.
Once you’ve gathered these, you’re ready to begin.
Step 1: Connect Your Dahua DVR to Your Router
The first step is physically connecting your DVR to your network.
Locate the Ethernet Port
On the back of your Dahua DVR, you’ll see multiple ports—HDMI, USB, audio, and power. Look for the one labeled “LAN” or “Ethernet.” It usually has a small icon of a computer or network cable.
Plug in the Ethernet Cable
Take your Ethernet cable and connect one end to the DVR’s LAN port. Plug the other end into an available LAN port on your router. Avoid using the WAN port (usually labeled “Internet”)—that’s for your modem.
Power On the DVR
Turn on your DVR and wait for it to boot up. You should see the main menu or camera feeds on your monitor. If you don’t have a monitor connected, that’s okay—you can still proceed, but a display helps with initial setup.
Check the Network Status
Once the DVR is on, go to the main menu (usually accessed by right-clicking the mouse or pressing the Menu button on the remote). Navigate to Network > Network Status. You should see an IP address assigned (e.g., 192.168.1.108). If it shows “Disconnected” or “0.0.0.0,” double-check your cable and router connection.
Step 2: Configure Network Settings on the DVR
Now that your DVR is connected, it’s time to configure its network settings for internet access.
Access the Network Configuration Menu
From the main menu, go to Configuration > Network. Here, you’ll see options like TCP/IP, PPPoE, and Port settings.
Set a Static IP Address (Recommended)
By default, your DVR may use DHCP (automatic IP assignment). While this works, it’s better to assign a static IP so your DVR always has the same address. Here’s how:
- In the TCP/IP settings, change the mode from “DHCP” to “Static.”
- Enter an IP address within your router’s range (e.g., if your router is 192.168.1.1, use 192.168.1.108).
- Set the Subnet Mask to 255.255.255.0.
- Enter your router’s IP as the Gateway (e.g., 192.168.1.1).
- Set DNS servers (use your router’s IP or public DNS like 8.8.8.8 and 8.8.4.4).
Tip: Avoid using IP addresses already assigned to other devices (like your computer or printer). Check your router’s DHCP client list to see what’s in use.
Configure HTTP and Server Ports
These ports allow remote access:
- HTTP Port: Usually 80. You can change it to 81 or 8080 if port 80 is blocked by your ISP.
- Server Port: Typically 37777. This is used for data transfer and remote control.
Write these down—you’ll need them later for port forwarding.
Save and Reboot
After entering the settings, click “Save” or “Apply.” The DVR may restart. Wait for it to come back online.
Step 3: Enable P2P (Peer-to-Peer) for Easy Remote Access
Dahua’s P2P feature is the easiest way to connect your DVR to the internet without dealing with complex router settings. It works by linking your DVR to Dahua’s cloud servers, allowing you to access it via a unique QR code or serial number.
Enable P2P in the DVR Menu
Go to Configuration > Network > P2P. Toggle “Enable” to ON. You’ll see a QR code and a serial number (also called a S/N or Device ID).
Download and Open the DMSS App
On your smartphone, open the DMSS app. Tap the “+” icon to add a device.
Scan the QR Code
Use the app’s camera to scan the QR code displayed on your DVR screen. The app will automatically detect your device and prompt you to enter a name (e.g., “Home Security”) and password.
Log In and View Live Feed
Enter your DVR’s login credentials (default is usually admin / admin). Once connected, you’ll see live camera feeds. You can now access your DVR from anywhere with internet!
Note: P2P requires an active internet connection on both your DVR and your phone. It also relies on Dahua’s servers, so if their service is down, remote access may be affected.
Step 4: Set Up Port Forwarding (Alternative to P2P)
If P2P isn’t working or your DVR doesn’t support it, you’ll need to set up port forwarding on your router. This method gives you direct access but requires more technical steps.
Find Your DVR’s Local IP Address
Go back to Network > Network Status on your DVR and note the IP address (e.g., 192.168.1.108).
Log Into Your Router
Open a web browser on a computer connected to the same network. Type your router’s IP address (usually 192.168.1.1 or 192.168.0.1) into the address bar. Log in with your router’s admin credentials (check the router label or manual if you don’t know them).
Locate Port Forwarding Settings
Navigate to the port forwarding section. It may be under:
– Advanced Settings > Port Forwarding
– NAT > Virtual Servers
– Firewall > Port Forwarding
The exact location varies by router brand (TP-Link, Netgear, ASUS, etc.).
Add a New Port Forwarding Rule
Create a new rule with the following details:
- Service Name: Dahua_DVR (or any name you prefer)
- External Port: 80 (HTTP) and 37777 (Server)
- Internal IP: Your DVR’s static IP (e.g., 192.168.1.108)
- Internal Port: Same as external (80 and 37777)
- Protocol: TCP (or Both TCP/UDP)
Save the rule. Some routers require a reboot.
Find Your Public IP Address
Go to a site like whatismyip.com from a device on your network. This is your public IP—the address outsiders use to reach your network.
Access Your DVR Remotely
On a computer outside your network (or using mobile data), open a browser and type:
http://[Your_Public_IP]:80
or
http://[Your_Public_IP]:37777
You should see the Dahua login page. Enter your credentials to access the DVR.
Warning: Using your public IP directly is less secure. Consider using a Dynamic DNS (DDNS) service if your IP changes often.
Step 5: Set Up DDNS (Dynamic DNS) for Changing IPs
Most home internet connections have dynamic IPs—they change periodically. DDNS solves this by linking a domain name (like yourname.dahuaddns.com) to your changing IP.
Enable DDNS on Your DVR
Go to Configuration > Network > DDNS. Select “Enable” and choose a DDNS provider (Dahua supports dyndns.org, no-ip.com, and their own service).
Register a DDNS Account
Visit the provider’s website (e.g., no-ip.com) and create a free account. Choose a hostname (e.g., mydahua.ddns.net).
Enter DDNS Details on the DVR
Back in the DVR menu, enter:
– Server address (e.g., dynupdate.no-ip.com)
– Your DDNS username and password
– The hostname you created
Save and test the connection. The DVR should update your IP automatically.
Now, instead of using your public IP, you can access your DVR via:
http://mydahua.ddns.net:80
Step 6: Use the Dahua Mobile App for Remote Viewing
The DMSS app is the easiest way to monitor your system on the go.
Add Your DVR via P2P (Recommended)
Open DMSS, tap “+”, scan the QR code from your DVR’s P2P menu, and log in.
Add Manually (If P2P Fails)
Tap “Manual Add,” enter:
– Device name
– IP address (use public IP or DDNS hostname)
– Port (80 or 37777)
– Username and password
Tap “Save” and connect.
Enable Push Notifications
In the app, go to device settings and enable motion detection alerts. You’ll get instant notifications when activity is detected.
View Live Feeds and Playback
Tap any camera to view live video. Use the playback feature to review recorded footage by date and time.
Step 7: Secure Your Dahua DVR
Now that your DVR is online, security is crucial.
Change Default Passwords
Immediately change the default admin password. Use a strong combination of letters, numbers, and symbols.
Disable Unused Services
Turn off Telnet, FTP, or HTTP if you don’t need them. Go to Configuration > Network > Advanced and disable unnecessary protocols.
Update Firmware
Check for firmware updates in Maintenance > Upgrade. Updated firmware patches security vulnerabilities.
Use a Firewall
Ensure your router’s firewall is enabled. Consider placing the DVR on a separate VLAN or guest network to isolate it from other devices.
Monitor Access Logs
Regularly check login logs in Maintenance > Log to spot unauthorized access attempts.
Troubleshooting Common Issues
Even with careful setup, problems can arise. Here’s how to fix the most common ones.
Can’t Access DVR Remotely
- Check if your DVR has internet access (ping it from another device).
- Verify port forwarding rules are correct.
- Ensure your ISP isn’t blocking ports (some block port 80).
- Try using a different port (e.g., 8080 instead of 80).
P2P Not Working
- Confirm P2P is enabled on the DVR.
- Check if your DVR’s serial number is valid (no typos).
- Restart the DVR and router.
- Ensure your internet connection is stable.
