Before diving into the technical steps, it’s important to understand why a static IP is crucial for your Dahua DVR.
Most home and small business networks use DHCP (Dynamic Host Configuration Protocol), which automatically assigns IP addresses to devices. While convenient, DHCP can cause problems for security systems. Every time your DVR reboots or loses power, it might get a new IP address. This means any remote access links, mobile apps, or third-party integrations could stop working until you update the new IP.
A static IP solves this by giving your DVR a permanent address on your network. Think of it like giving your DVR a fixed home address—no matter how many times it restarts, it always lives at the same location. This is essential if you want to:
– Access your cameras remotely via the internet
– Set up port forwarding for remote viewing
– Integrate with third-party software or NVRs
– Use DDNS (Dynamic DNS) services reliably
In short, a static IP ensures your Dahua DVR remains accessible and predictable on your network.
What You’ll Need Before Starting
Before you begin, make sure you have the following:
- A Dahua DVR connected to your network: The DVR should be powered on and connected via Ethernet cable to your router or switch.
- A computer or laptop on the same network: You’ll need to access the DVR’s interface from a device that shares the local network.
- Router login credentials: You’ll need the admin username and password for your router to reserve the IP address.
- Basic knowledge of your network: Know your router’s IP address (usually 192.168.1.1 or 192.168.0.1), subnet mask (typically 255.255.255.0), and DNS servers.
- Dahua Config Tool (optional): A free utility from Dahua that helps discover and configure DVRs on your network.
Having these ready will make the process smooth and error-free.
Step 1: Access the Dahua DVR Interface
The first step is to access the DVR’s configuration menu. You can do this in two ways: through the DVR’s built-in web interface or using the Dahua Config Tool.
Method A: Using the Web Interface
- Find the DVR’s current IP address: If you don’t know it, check the DVR’s network settings via the on-screen display (OSD). Press the Menu button on the DVR or remote, go to Network > TCP/IP, and note the IP address.
- Open a web browser: On your computer, open Chrome, Firefox, or Edge.
- Enter the DVR’s IP address: Type the IP (e.g., http://192.168.1.108) into the address bar and press Enter.
- Log in: Use the default username and password (usually admin/admin or admin/123456). If you’ve changed it, use your custom credentials.
Method B: Using Dahua Config Tool
- Download and install the tool: Get it from the official Dahua website under Support > Software Downloads.
- Launch the Config Tool: It will scan your network and list all Dahua devices.
- Select your DVR: Click on it to view its current IP and MAC address.
- Click “Modify” to change settings: This opens a window where you can adjust the IP configuration.
Either method works, but the web interface gives you more control and is better for detailed configuration.
Step 2: Configure Static IP on the DVR
Now that you’re logged in, it’s time to assign a static IP to your DVR.
Navigate to Network Settings
- In the web interface, go to Setup > Network > TCP/IP.
- You’ll see fields for IP Address, Subnet Mask, Gateway, and DNS.
Choose a Static IP Address
Pick an IP address that’s outside your router’s DHCP range to avoid conflicts. For example, if your router assigns IPs from 192.168.1.100 to 192.168.1.200, choose something like 192.168.1.50.
Example Configuration:
- IP Address: 192.168.1.50
- Subnet Mask: 255.255.255.0
- Gateway: 192.168.1.1 (your router’s IP)
- Preferred DNS: 8.8.8.8 (Google DNS)
- Alternate DNS: 8.8.4.4
Save the Settings
- Click Save or Apply.
- The DVR may restart or lose connection temporarily—this is normal.
- Wait 30–60 seconds for the DVR to reconnect with the new IP.
Reconnect to the DVR
Since the IP has changed, you’ll need to access it using the new address. Open your browser and go to http://192.168.1.50 (or whatever IP you set). Log in again to confirm the settings are active.
Step 3: Reserve the IP in Your Router
Even though you’ve set a static IP on the DVR, your router might still try to assign that address to another device via DHCP. To prevent this, you need to reserve the IP in your router.
Log into Your Router
- Open a browser and enter your router’s IP (e.g., 192.168.1.1).
- Log in with your admin credentials.
Find DHCP Reservation Settings
The exact location varies by router brand, but look for:
- “DHCP Reservation”
- “Address Reservation”
- “Static DHCP”
- “LAN Settings” > “DHCP Server”
Common locations:
- TP-Link: Advanced > Network > DHCP Server > Address Reservation
- Netgear: Advanced > Setup > LAN Setup > Address Reservation
- ASUS: LAN > DHCP Server > Manual Assignment
Add a Reservation
- Find your DVR in the list of connected devices (use the MAC address from the DVR’s network settings or Config Tool).
- Select the device and assign it the static IP you configured (e.g., 192.168.1.50).
- Save the changes.
Now, even if the DVR reboots, the router will always assign it the same IP.
Step 4: Configure Port Forwarding (Optional but Recommended)
To access your Dahua DVR remotely over the internet, you’ll need to set up port forwarding. This tells your router to forward incoming requests on specific ports to your DVR.
Find the DVR’s Port Numbers
In the DVR’s web interface, go to Setup > Network > Port. Note the following default ports:
- HTTP Port: 80 (for web access)
- RTSP Port: 554 (for video streaming)
- Server Port: 37777 (for mobile app and remote access)
You can change these if needed, but avoid common ports like 80 if you’re using them for other services.
Set Up Port Forwarding in Your Router
- In your router’s admin panel, go to Port Forwarding or Virtual Server.
- Add a new rule:
- Service Name: Dahua_DVR
- External Port: 37777
- Internal IP: 192.168.1.50 (your DVR’s static IP)
- Internal Port: 37777
- Protocol: TCP (or Both)
- Repeat for HTTP (port 80) and RTSP (port 554) if needed.
- Save the settings.
Test Port Forwarding
Use a tool like YouGetSignal to check if port 37777 is open. Enter your public IP (find it via whatismyip.com) and the port number. If it shows “Open,” you’re good to go.
Step 5: Set Up Remote Access
Now that your DVR has a static IP and port forwarding is enabled, you can access it from anywhere.
Use the Dahua Mobile App
- Download Dahua Mobile (iOS or Android).
- Open the app and tap Add Device.
- Choose Manual Add.
- Enter:
- Device Name: Home DVR
- IP Address: Your public IP (from whatismyip.com)
- Port: 37777
- Username and Password: Your DVR login
- Tap Save and test the connection.
Use the Web Portal
Go to Dahua Security and log in with your Dahua account. Add your DVR using the serial number or scan the QR code on the device. Once added, you can view live feeds and playback recordings from any browser.
Troubleshooting Common Issues
Even with careful setup, problems can arise. Here’s how to fix the most common ones.
Can’t Access the DVR After Changing IP
- Cause: You’re still using the old IP in your browser.
- Solution: Clear your browser cache or use a private window. Enter the new static IP (e.g., 192.168.1.50).
Port Forwarding Not Working
- Cause: ISP blocking ports, incorrect settings, or firewall interference.
- Solution: Try changing the server port to something above 10000 (e.g., 37888). Disable Windows Firewall temporarily to test. Contact your ISP if they block common ports.
IP Conflict Detected
- Cause: Another device is using the same IP.
- Solution: Double-check your router’s DHCP reservation. Reboot the DVR and router. Use the Config Tool to scan for conflicts.
Remote Access Fails Intermittently
- Cause: Dynamic public IP from ISP.
- Solution: Use a DDNS service like No-IP or DynDNS. Dahua also offers its own DDNS—enable it in Setup > Network > DDNS.
Slow or Laggy Video Stream
- Cause: Bandwidth limits or incorrect stream settings.
- Solution: In the DVR, go to Setup > Camera > Encode and lower the resolution or bitrate for the sub-stream used by mobile apps.
Best Practices for Long-Term Stability
To keep your Dahua DVR running smoothly:
- Update firmware regularly: Check Dahua’s website every few months for updates that improve security and performance.
- Use strong passwords: Change the default admin password and use a mix of letters, numbers, and symbols.
- Enable HTTPS: In Setup > Network > HTTPS, enable secure browsing to protect login credentials.
- Monitor logs: Check the system log (Maintenance > Log) for errors or unauthorized access attempts.
- Backup configuration: In Maintenance > Backup, save your settings to a USB drive in case you need to restore them.
