Before diving into the setup process, make sure you have the following:
- A Dahua DVR with network capability: Most modern Dahua DVRs support Ethernet and remote access. Check your model number (e.g., XVR5104HS, DHI-XVR5108HS) to confirm it has an RJ45 Ethernet port.
- An active internet connection: Your DVR needs to be connected to a router with internet access.
- An Ethernet cable: To connect the DVR to your router.
- A PC or laptop: Running Windows (Windows 7, 8, 10, or 11 recommended).
- Router access: You’ll need admin access to your router to configure port forwarding.
- Dahua software: We’ll use SmartPSS (Smart Professional Surveillance System) or ConfigTool—both free and available from Dahua’s official website.
Having these ready will save you time and frustration during setup.
Step 1: Connect Your Dahua DVR to the Network
The first step in getting your Dahua DVR online is physically connecting it to your local network.
Power On the DVR
Make sure your DVR is powered on and all cameras are connected. You should see the main menu or live view on the monitor attached to the DVR.
Connect via Ethernet Cable
Take an Ethernet cable and plug one end into the LAN port on your Dahua DVR (usually labeled “LAN” or “NET”). Plug the other end into an available port on your router or network switch.
Tip: Avoid using the “PC” or “LAN2” port if your DVR has one—those are often for direct PC connection and won’t work for internet access.
Once connected, the DVR should automatically detect the network. You’ll usually see a network icon or status light on the DVR interface indicating a successful connection.
Step 2: Configure Network Settings on the DVR
Now that your DVR is physically connected, it’s time to configure its network settings so it can communicate over the internet.
Access the DVR Menu
Using a mouse connected to the DVR or the front panel buttons, navigate to the main menu. Look for a section labeled “Network”, “Network Settings”, or “System” > “Network”.
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 address so the DVR’s address doesn’t change, which could break remote access.
Here’s how:
- In the Network settings, find the TCP/IP or IPv4 section.
- Change the mode from “DHCP” to “Manual” or “Static”.
- Enter an IP address that’s within your router’s range but outside the DHCP pool. For example, if your router is 192.168.1.1 and assigns addresses from 192.168.1.100 to 192.168.1.200, use something like 192.168.1.50.
- Set the subnet mask to 255.255.255.0 (common for home networks).
- Set the gateway to your router’s IP (e.g., 192.168.1.1).
- Set DNS servers—use your router’s IP or public DNS like 8.8.8.8 (Google) and 8.8.4.4.
Example:
IP: 192.168.1.50
Subnet: 255.255.255.0
Gateway: 192.168.1.1
DNS: 8.8.8.8, 8.8.4.4
Save the settings and reboot the DVR if prompted.
Verify Network Connection
After saving, go back to the network status page. You should see the assigned IP address and a “Connected” status. You can also try pinging the DVR from your PC to confirm it’s reachable:
- Open Command Prompt on your PC (press Win + R, type
cmd, press Enter). - Type
ping 192.168.1.50(replace with your DVR’s IP). - If you get replies, the DVR is online on your local network.
Step 3: Install Dahua Software on Your PC
To access your DVR remotely, you’ll need software that can communicate with it. Dahua provides free tools for this.
Download SmartPSS or ConfigTool
Go to the official Dahua website (www.dahuasecurity.com) and navigate to the Support or Downloads section.
Search for your DVR model and download:
- SmartPSS: A full-featured client for live viewing, playback, backup, and device management.
- ConfigTool: A lighter tool for device discovery and basic configuration.
We recommend SmartPSS for most users because it offers the most functionality.
Install the Software
Run the installer and follow the on-screen instructions. Accept the license agreement, choose the installation folder, and complete the setup.
Once installed, launch SmartPSS.
Add Your DVR to SmartPSS
- In SmartPSS, click the “Device Manager” tab.
- Click “Add” or the “+” icon.
- Enter the following:
- Device Name: e.g., “Home DVR”
- IP Address: The static IP you assigned (e.g., 192.168.1.50)
- Port: 37777 (default for Dahua devices)
- Username: admin (default)
- Password: The password you set during DVR setup (default is often blank or “admin”)
- Click “Add”.
If everything is correct, the device should appear in the list with a green status indicating it’s online.
Tip: If you can’t add the device, double-check the IP, port, and password. Also ensure your PC and DVR are on the same network.
Step 4: Enable Remote Access via Port Forwarding
Now that your DVR is accessible on your local network, it’s time to make it available from the internet—so you can access it from anywhere.
This requires port forwarding on your router.
Find Your Router’s Public IP Address
On your PC, open a browser and go to whatismyip.com. Note down the IP address shown—this is your public (WAN) IP.
Note: If your ISP assigns a dynamic IP (which changes periodically), you’ll need DDNS—we’ll cover that next.
Log in to Your Router
Open a browser and enter your router’s IP address (usually 192.168.1.1 or 192.168.0.1). Log in with your admin username and password.
Set Up Port Forwarding
Look for a section called “Port Forwarding”, “Virtual Server”, or “NAT”. The exact name varies by router brand (TP-Link, Netgear, ASUS, etc.).
Add a new rule with the following settings:
- Service Name: Dahua DVR
- External Port: 37777 (for device communication)
- Internal IP: 192.168.1.50 (your DVR’s static IP)
- Internal Port: 37777
- Protocol: TCP (sometimes select “Both” for TCP/UDP)
You may also need to forward port 80 (HTTP) if you want to access the DVR’s web interface.
Save the settings and reboot the router if required.
Test Remote Access
Now, try accessing your DVR from outside your home network:
- On a different network (e.g., mobile data or a friend’s Wi-Fi), open SmartPSS.
- In the device settings, change the IP address from the local IP (192.168.1.50) to your public IP (e.g., 123.45.67.89).
- Keep the port as 37777.
- Click “Connect”.
If successful, you’ll see live camera feeds. Congratulations—your Dahua DVR is now online and accessible from your PC anywhere!
Step 5: Set Up DDNS for Dynamic IP Addresses (Optional but Recommended)
Most home internet connections use dynamic IP addresses, meaning your public IP changes periodically. This breaks remote access unless you update it every time.
To solve this, use a DDNS (Dynamic DNS) service.
Register a DDNS Account
Dahua offers a free DDNS service called Dahua DDNS. Alternatively, you can use third-party services like No-IP or DynDNS.
To use Dahua DDNS:
- Go to www.dahuaddns.com.
- Create a free account.
- Log in and register a domain name (e.g., myhomedvr.dahuaddns.com).
Enable DDNS on the DVR
Back on your DVR:
- Go to Network > DDNS.
- Enable DDNS.
- Select “Dahua” as the service provider.
- Enter your DDNS username and password.
- Enter the domain name you registered (e.g., myhomedvr.dahuaddns.com).
- Save and apply.
Now, even if your public IP changes, the DDNS service will update the domain to point to the new IP.
Update SmartPSS with DDNS
In SmartPSS, edit your device settings:
- Change the IP address field to your DDNS domain (e.g., myhomedvr.dahuaddns.com).
- Keep the port as 37777.
Now you can access your DVR using a consistent web address, no matter how often your IP changes.
Step 6: Access Your DVR via Web Browser (Alternative Method)
You can also access your Dahua DVR directly through a web browser—no software needed.
Find the DVR’s Web Interface
On your PC (on the same network), open a browser and enter:
http://192.168.1.50 (replace with your DVR’s IP)
You should see the Dahua login page.
Log In
Enter your username (usually “admin”) and password.
Once logged in, you’ll see a live view of your cameras. You can also access playback, settings, and recordings.
Note: For remote access, use your public IP or DDNS domain instead of the local IP (e.g., http://myhomedvr.dahuaddns.com).
Troubleshooting Common Issues
Even with careful setup, you might run into problems. Here’s how to fix the most common ones.
Can’t Connect to DVR on Local Network
- Check the Ethernet cable and ensure the DVR is powered on.
- Verify the IP address in the DVR menu matches what you’re using.
- Try pinging the DVR from your PC.
- Restart the DVR and router.
Port Forwarding Not Working
- Double-check the port numbers (37777 for Dahua).
- Ensure the internal IP is correct and static.
- Disable the Windows firewall temporarily to test.
- Some ISPs block port 80—try using a different port (e.g., 8080) and forward that instead.
DDNS Not Updating
- Confirm your DDNS account is active and the domain is registered.
- Check that the DVR has internet access (ping a website from the DVR menu if possible).
- Re-enter DDNS credentials on the DVR.
Slow or Laggy Video
- Reduce the stream quality in the DVR settings (use Sub-Stream for remote viewing).
- Check your internet upload speed—remote viewing depends on how fast you can send data from home.
- Close other bandwidth-heavy apps on your network.
Forgot DVR Password
If you’ve forgotten the admin password:
- Contact Dahua support with your DVR’s serial number.
- They can provide a reset code based on the device’s timestamp.
- Alternatively, perform a hard reset (usually via a button on the DVR)—but this will erase all settings.
Security Tips for Remote DVR Access
Now that your DVR is online, security is crucial.
- Change the default password: Use a strong, unique password for the admin account.
- Disable UPnP: Universal Plug and Play can open ports automatically—turn it off to prevent unauthorized access.
- Update firmware: Regularly check for and install firmware updates from Dahua to patch security vulnerabilities.
- Use HTTPS/SSL: If your DVR supports it, enable encrypted connections.
- Limit access: Only share your DDNS or IP with trusted users.
