Before diving into the technical steps, let’s talk about why networking your Dahua DVR is so valuable.
First, remote access lets you view live video feeds and recorded footage from your smartphone, tablet, or computer—whether you’re at work, on vacation, or just in another room. That means you can check if the kids got home safely, monitor deliveries, or keep an eye on your business after hours.
Second, networked DVRs support alerts and notifications. If motion is detected, your Dahua system can send you a push notification or email, so you’re always in the loop.
Third, internet connectivity allows for cloud backups and firmware updates, keeping your system secure and up to date.
In short, networking your Dahua DVR transforms it from a local recording device into a smart, connected security hub.
What You’ll Need Before You Start
Before we begin, make sure you have the following:
- A Dahua DVR (any model with network capabilities)
- An Ethernet cable (Cat5e or Cat6 recommended)
- A working internet connection with a router
- Access to your router’s admin panel (usually via a web browser)
- The DVR’s local IP address (we’ll show you how to find it)
- A computer or smartphone for setup
- The DMSS mobile app (free on iOS and Android)
Most Dahua DVRs come with built-in network ports, so you won’t need extra hardware. Just make sure your internet speed is sufficient—at least 2 Mbps upload speed is recommended for smooth remote viewing.
Step 1: Connect Your Dahua DVR to the Network
The first step is physically connecting your DVR to your home or office network.
Use an Ethernet Cable
Take an Ethernet cable and plug one end into the LAN port on your Dahua DVR. The LAN port is usually labeled and located on the back of the unit. Plug the other end into an available port on your router or network switch.
Avoid using Wi-Fi adapters unless your DVR model specifically supports them. Wired connections are more stable and secure for surveillance systems.
Power On the DVR
Make sure your DVR is powered on and connected to your cameras. Wait a minute or two for the system to boot up fully. You should see the main menu or live view on your monitor.
Check the Network Connection
Once connected, the DVR should automatically detect the network. Look for a network icon or status light on the DVR’s interface. If it shows “Connected” or “Online,” you’re off to a good start.
If not, double-check the cable and router connection. Try a different Ethernet port on the router if needed.
Step 2: Access the DVR’s Network Settings
Now it’s time to configure the network settings directly on your Dahua DVR.
Open the Main Menu
Using the DVR’s remote control or mouse (if supported), navigate to the main menu. This is usually accessed by pressing the “Menu” button or right-clicking on the screen.
Go to Network Settings
In the menu, look for a section called “Network,” “Network Configuration,” or “System Settings.” Click or select it.
You’ll see several options, including:
- TCP/IP
- DDNS
- P2P (Peer-to-Peer)
- Port Settings
- UPnP
We’ll focus on the TCP/IP settings first.
Set a Static IP Address (Recommended)
By default, your DVR may use DHCP, which means it gets an IP address automatically from your router. While this works, it’s better to assign a static (fixed) IP address so your DVR always has the same local address.
Here’s how:
- In the TCP/IP settings, change the “IP Address” to a static one. Choose an IP in your router’s range (e.g., if your router is 192.168.1.1, use 192.168.1.100).
- Set the “Subnet Mask” to 255.255.255.0 (common for home networks).
- Enter the “Gateway” as your router’s IP (usually 192.168.1.1 or 192.168.0.1).
- Set “DNS Server” to your router’s IP or use public DNS like 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
- Save the settings.
Example:
- IP Address: 192.168.1.100
- Subnet Mask: 255.255.255.0
- Gateway: 192.168.1.1
- DNS: 8.8.8.8
After saving, the DVR may restart its network connection. Wait a moment, then verify the connection is active.
Step 3: Find Your DVR’s Local IP Address
If you didn’t set a static IP, or you’re unsure of the current address, here’s how to find it.
Check the DVR’s Network Status
Go back to the Network settings and look for “TCP/IP” or “Network Status.” The current IP address should be displayed.
Use the Router’s Admin Panel
Alternatively, log in to your router’s admin page (usually by typing 192.168.1.1 into a web browser). Look for a section like “Connected Devices,” “DHCP Clients,” or “Attached Devices.” Your DVR should appear with a name like “Dahua” or “DVR” and its assigned IP.
Write down this IP address—you’ll need it for port forwarding.
Step 4: Set Up Port Forwarding on Your Router
Port forwarding tells your router to send incoming internet traffic on specific ports directly to your DVR. This is essential for remote access.
Log in to Your Router
Open a web browser and enter your router’s IP address (e.g., 192.168.1.1). Log in with your admin username and password. If you haven’t changed it, check the router’s label or manual for defaults.
Find the Port Forwarding Section
Look for a menu called “Port Forwarding,” “Virtual Servers,” “NAT,” or “Applications & Gaming.” The exact name varies by router brand (e.g., TP-Link, Netgear, ASUS).
Add a New Port Forwarding Rule
Create a new rule with the following details:
- Service Name: Dahua DVR (or any name you like)
- External Port Start: 80
- External Port End: 80
- Internal IP Address: Your DVR’s local IP (e.g., 192.168.1.100)
- Internal Port: 80
- Protocol: TCP (or Both)
Repeat this for the media and mobile ports:
- Port 37777 (for video streaming)
- Port 37778 (for mobile app access)
So you’ll have three rules total:
- Port 80 → 192.168.1.100:80 (HTTP)
- Port 37777 → 192.168.1.100:37777 (Media)
- Port 37778 → 192.168.1.100:37778 (Mobile)
Save the settings and restart your router if prompted.
Test the Ports
Use an online port checker (like canyouseeme.org) to verify that ports 80, 37777, and 37778 are open. Enter your public IP address and the port number. If it says “Success,” you’re good to go.
Step 5: Set Up DDNS (Dynamic DNS)
Most home internet connections use dynamic IP addresses, which change periodically. DDNS solves this by linking a fixed domain name to your changing IP.
Why Use DDNS?
Without DDNS, you’d need to check your public IP every time it changes and update your access method. DDNS automates this, so you can always reach your DVR using a simple web address like “myhome.dahua.com.”
Use Dahua’s Free DDNS Service
Dahua offers a free DDNS service called “Dahua DDNS.” Here’s how to set it up:
- In the DVR’s Network menu, go to “DDNS.”
- Enable DDNS and select “Dahua” as the provider.
- Create a free account at dahuasecurity.com or use an existing one.
- Enter your username and password in the DVR settings.
- Set a domain name (e.g., mydvr.dahua.com).
- Save and enable the service.
The DVR will now update its IP address with Dahua’s servers automatically.
Alternative: Use No-IP or DynDNS
If you prefer, you can use third-party DDNS services like No-IP or DynDNS. The process is similar:
- Sign up for a free account and create a hostname (e.g., mydvr.ddns.net).
- In the DVR’s DDNS settings, select “Custom” or “No-IP.”
- Enter your hostname, username, and password.
- Save and enable.
Now you can access your DVR using the DDNS hostname instead of a changing IP.
Step 6: Enable Remote Access via Web Browser
Once your DVR is networked and ports are forwarded, you can access it from any web browser.
Find Your Public IP or DDNS Address
If you’re not using DDNS, find your public IP by searching “what is my IP” in Google. If using DDNS, use your custom domain (e.g., mydvr.dahua.com).
Enter the Address in a Browser
Open a web browser on any device (computer, phone, tablet) and type:
http://[your-public-IP]:80
or
http://mydvr.dahua.com:80
You should see the Dahua login page.
Log In to the DVR
Enter your DVR’s admin username and password. The default is often “admin” with password “admin” or blank—but you should change this immediately for security.
Once logged in, you’ll see the live view or playback interface. You can now monitor your cameras from anywhere!
Step 7: Use the DMSS Mobile App
For the best mobile experience, download the DMSS app (Dahua Mobile Surveillance System) from the App Store or Google Play.
Add Your DVR to the App
- Open the DMSS app and tap “+” to add a device.
- Choose “Manual Add” or “Scan QR Code” (if your DVR has a QR code).
- Enter the following:
- Device Name: Home DVR
- IP Address: Your public IP or DDNS hostname
- Port: 37777 (or 37778 for mobile)
- Username and Password
- Tap “Save” or “Connect.”
The app will attempt to connect. If successful, you’ll see live camera feeds.
Enable P2P (Optional but Recommended)
Many Dahua DVRs support P2P (Peer-to-Peer) connectivity, which simplifies setup. With P2P, you don’t need to configure port forwarding or DDNS.
To enable P2P:
- In the DVR’s Network menu, go to “P2P.”
- Enable P2P and note the QR code or serial number.
- In the DMSS app, scan the QR code or enter the serial number.
- Log in with your DVR credentials.
P2P uses Dahua’s cloud servers to connect your device securely. It’s the easiest method for most users.
Step 8: Secure Your Dahua DVR
Now that your DVR is online, security is critical. Hackers often target poorly secured surveillance systems.
Change Default Passwords
Immediately change the default admin password. Use a strong, unique password with uppercase, lowercase, numbers, and symbols.
Enable HTTPS
In the Network settings, enable HTTPS (port 443) for encrypted web access. This prevents snooping on your login and video streams.
Disable Unused Services
Turn off services you don’t need, like Telnet or FTP, to reduce attack surfaces.
Enable IP Filtering
Restrict access to specific IP addresses if possible. For example, only allow connections from your home or office IP.
Update Firmware Regularly
Check for firmware updates in the DVR’s System menu. Updated firmware includes security patches and bug fixes.
Troubleshooting Common Issues
Even with careful setup, you might run into problems. Here’s how to fix the most common ones.
Can’t Access DVR Remotely
- Check that the DVR is powered on and connected to the network.
- Verify the local IP address hasn’t changed.
- Ensure port forwarding rules are correct and active.
- Test with a different device or network (e.g., mobile data).
- Restart the DVR and router.
Port Forwarding Not Working
- Confirm the external and internal ports match.
- Make sure the DVR’s IP is static.
- Check if your ISP blocks common ports (like 80). Try using port 8080 instead.
- Disable the router’s firewall temporarily to test.
DDNS Not Updating
- Verify your DDNS credentials are correct.
- Check that the DVR has internet access.
- Ensure the DDNS service is enabled and active.
- Try rebooting the DVR.
Slow or Laggy Video
- Check your upload speed (use speedtest.net).
- Reduce video resolution or frame rate in the DVR settings.
- Use a wired connection instead of Wi-Fi.
- Limit the number of remote users.
DMSS App Won’t Connect
- Ensure you’re using the correct port (37777 or 37778).
- Check that P2P is enabled if using that method.
- Update the DMSS app to the latest version.
- Try removing and re-adding the device.
