Let’s get started!
What You’ll Need Before You Begin
Before diving into the configuration process, make sure you have the following:
- A Dahua DVR or NVR system – This guide applies to most Dahua digital video recorders and network video recorders.
- An active internet connection – Your DVR must be connected to a router with internet access.
- Ethernet cable – To connect the DVR to your router.
- A computer or smartphone – For initial setup and remote access.
- Dahua software – Download ConfigTool, SmartPSS, or the DMSS mobile app (available on iOS and Android).
- Your DVR’s serial number or QR code – Usually found on a label on the device or in the user manual.
Having these items ready will make the setup process smooth and hassle-free.
Step 1: Connect Your Dahua DVR to the Internet
The first step in configuring your Dahua DVR online is connecting it to your local network.
Connect via Ethernet Cable
Most Dahua DVRs have an Ethernet port (RJ45) on the back. Use an Ethernet cable to connect this port to one of the LAN ports on your router.
Once connected, the DVR will automatically obtain an IP address from your router using DHCP (Dynamic Host Configuration Protocol). This is the standard method and works for most home and small business networks.

Verify Network Connection
To confirm the DVR is online:
- Power on the DVR and wait for it to boot up.
- Connect a monitor and mouse to the DVR (if not already done).
- Navigate to Main Menu > Network > TCP/IP.
- Check that the IP address, subnet mask, gateway, and DNS settings are populated.
If the IP address starts with 192.168.x.x or 10.x.x.x, it means the DVR has successfully connected to your local network.
Tip: Write down the IP address—you’ll need it later for remote access.
Step 2: Access the DVR’s Web Interface
Now that your DVR is on the network, you can access its settings through a web browser.
Find the DVR’s IP Address
If you didn’t note it earlier, you can find the IP address by:
- Using the DVR’s on-screen menu (Main Menu > Network > TCP/IP).
- Running Dahua’s ConfigTool software on a computer on the same network. The tool will scan and display all Dahua devices.
Log in via Web Browser
Open a web browser (Chrome, Firefox, or Edge) and type the DVR’s IP address into the address bar. Press Enter.
You’ll see a login screen. Enter the default username and password:
- Username: admin
- Password: admin (or the password you set during initial setup)
Important: If this is your first time logging in, the system may prompt you to change the default password. Do this immediately for security.
Once logged in, you’ll see the DVR’s web interface. This is where you can configure network settings, camera views, and remote access.
Step 3: Enable P2P (Plug-and-Play) for Easy Remote Access
Dahua’s P2P (Peer-to-Peer) technology is the easiest way to access your DVR remotely without dealing with complex network settings like port forwarding.
What Is P2P?
P2P allows your DVR to connect directly to Dahua’s cloud servers. When you use the DMSS app or SmartPSS, it communicates with the cloud, which then connects to your DVR. This bypasses the need to open ports on your router.
Enable P2P on Your DVR
Follow these steps:
- In the DVR’s web interface, go to Main Menu > Network > P2P.
- Check the box for Enable P2P.
- Make sure the Status shows “Online” or “Connected”.
- Note the Serial Number or scan the QR code displayed on the screen.
Tip: The serial number is unique to your DVR and is used to add it to mobile apps.
Test P2P Status
If the status shows “Offline,” check your internet connection and ensure the DVR has outbound access to Dahua’s servers (usually port 37777). Some firewalls or ISPs may block this—contact your provider if needed.
Step 4: Set Up Remote Access Using the DMSS Mobile App
The DMSS (Dahua Mobile Surveillance System) app is the official mobile app for viewing Dahua devices on iOS and Android.
Download and Install DMSS
Go to the App Store (iOS) or Google Play Store (Android) and search for “DMSS.” Download and install the app.
Add Your DVR Using P2P
- Open the DMSS app and tap the + icon to add a device.
- Select Add Device Manually.
- Choose DVR/NVR as the device type.
- Enter a name for your DVR (e.g., “Home Security”).
- Tap Serial Number and either type it in or scan the QR code from the DVR’s P2P screen.
- Enter the username and password (usually admin and your password).
- Tap Save.
The app will connect to your DVR via P2P. Once added, you’ll see live camera feeds on your phone.
View Live Video and Recordings
Tap on any camera to view live footage. You can also:
- Switch between cameras.
- Take snapshots.
- Start/stop recording.
- Playback recorded video by selecting a date and time.
Pro Tip: Enable push notifications in the app settings to receive alerts when motion is detected.
Step 5: Use SmartPSS for Desktop Remote Access
SmartPSS is Dahua’s desktop software for managing and viewing DVRs on Windows PCs.
Download and Install SmartPSS
Visit the official Dahua website and download SmartPSS for Windows. Install it on your computer.
Add Your DVR in SmartPSS
- Open SmartPSS and click Device Manager.
- Click Add and select DVR/NVR.
- Choose P2P as the connection method.
- Enter the DVR’s serial number and login credentials.
- Click OK to save.
Once added, you can view live video, playback recordings, manage users, and configure settings—all from your computer.
Remote Access from Outside Your Network
SmartPSS uses the same P2P connection as the mobile app, so you can access your DVR from any computer with internet access—no need to be on the same network.
Step 6: Configure DDNS (Dynamic DNS) for Advanced Users
If your internet service provider gives you a dynamic IP address (which changes periodically), you may want to set up DDNS to maintain consistent access.
What Is DDNS?
DDNS links your changing IP address to a fixed domain name (e.g., mydvr.dahuaddns.com). This way, even if your IP changes, you can still reach your DVR using the same web address.
Set Up DDNS on Your DVR
- In the DVR’s web interface, go to Main Menu > Network > DDNS.
- Enable DDNS.
- Select a DDNS provider (Dahua offers its own free service).
- Enter a domain name (e.g., myhome-dvr).
- Enter your username and password (create an account on the DDNS provider’s site if needed).
- Click Apply.
Once configured, you can access your DVR by typing the DDNS domain into a web browser (e.g., http://myhome-dvr.dahuaddns.com).
Note: DDNS is optional if you’re using P2P, but it’s useful for advanced setups or if P2P is blocked.
Step 7: Secure Your Dahua DVR
Security is critical when accessing your DVR online. Follow these best practices:
Change Default Passwords
Never leave the default admin password as “admin.” Create a strong, unique password with a mix of letters, numbers, and symbols.
Enable HTTPS and Encryption
In the DVR’s network settings, enable HTTPS for secure web access. This encrypts data between your device and the DVR.
Update Firmware Regularly
Check for firmware updates in Main Menu > Maintenance > Upgrade. Updated firmware fixes bugs and improves security.
Disable Unused Services
Turn off services like Telnet or FTP if you don’t need them. These can be entry points for hackers.
Use a Strong Wi-Fi Password
If your router is wireless, ensure it uses WPA3 or WPA2 encryption with a strong password.
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 the DVR Remotely
- Check P2P status: Make sure it shows “Online” in the DVR menu.
- Verify internet connection: Ensure the DVR has outbound access to the internet.
- Restart the DVR and router: Power cycle both devices.
- Re-add the device in DMSS/SmartPSS: Sometimes the connection gets corrupted.
Video is Lagging or Buffering
- Reduce stream quality: In the DVR settings, lower the resolution or bitrate for remote viewing.
- Check bandwidth: Streaming multiple cameras uses more data. Limit the number of live views.
- Use a wired connection: Wi-Fi can be unstable. Use Ethernet for the DVR if possible.
Login Failed or Access Denied
- Double-check username and password: Case-sensitive and exact spelling matter.
- Reset the password: Use the ConfigTool to reset the admin password if locked out.
- Ensure user permissions: The account must have remote access rights.
DDNS Not Working
- Verify DDNS settings: Ensure the domain, username, and password are correct.
- Check IP update: Some DDNS services require the DVR to send periodic updates.
- Test from outside the network: Use a mobile data connection to test remote access.
