Step 1: Connect Your Dahua DVR to the Internet
The first step in enabling P2P is ensuring your DVR is properly connected to the internet. Without this, remote access is impossible.
Connect via Ethernet Cable
The most reliable way to connect your DVR is using an Ethernet cable. Follow these steps:
- Locate the LAN port on the back of your Dahua DVR.
- Use a standard Ethernet cable to connect the DVR to one of the LAN ports on your router.
- Power on the DVR and wait for it to boot up (usually 1–2 minutes).
- Check the network status on the DVR’s main menu. Look for “Network” or “System Info” to confirm it has received an IP address from your router.
Verify Internet Access
Once connected, verify that the DVR can access the internet:
- Go to Main Menu > Network > TCP/IP.
- Ensure the IP address is assigned (usually starts with 192.168.x.x).
- Check that the gateway and DNS settings are correct (usually match your router’s IP).
- Test the connection by pinging a website from the DVR’s network settings (if supported).
If the DVR shows “No Internet” or fails to connect, double-check your cable, router settings, and network configuration.
Step 2: Enable P2P on Your Dahua DVR
Now that your DVR is online, it’s time to enable P2P functionality. This step is crucial—without it, remote access won’t work.
Access the DVR’s Web Interface
You can enable P2P directly from the DVR’s interface or via a web browser. Here’s how to do it using the built-in menu:
- Press the Menu button on your DVR remote or use the mouse if connected to a monitor.
- Navigate to System > Network > P2P.
- Ensure the P2P option is set to Enable.
- Note down the Serial Number or Device ID displayed on this screen—you’ll need it later.
- Save the settings and exit the menu.
Alternative: Use a Web Browser
If you prefer using a computer, you can access the DVR’s web interface:
- Open a web browser (Chrome, Firefox, Edge).
- Type the DVR’s IP address into the address bar (e.g., http://192.168.1.108).
- Log in using your admin credentials.
- Go to Configuration > Network > P2P.
- Enable P2P and note the Device ID.
- Click Save.
Once P2P is enabled, your DVR will register with Dahua’s cloud servers, allowing remote devices to locate it using the unique ID.
Step 3: Install and Set Up the DMSS App
The DMSS (Dahua Mobile Surveillance System) app is the easiest way to access your DVR remotely. It’s available for both iOS and Android and supports live viewing, playback, and push notifications.
Download the DMSS App
Follow these steps to get started:
- Open the App Store (iOS) or Google Play Store (Android).
- Search for “DMSS” or “DMSS Lite” (the Lite version is recommended for most users).
- Download and install the app.
- Open the app and allow necessary permissions (camera, microphone, notifications).
Add Your DVR Using P2P
Now, let’s add your DVR to the app:
- Tap the + icon or “Add Device” on the home screen.
- Select P2P as the connection method.
- Enter the Device ID (Serial Number) you noted earlier.
- Enter your DVR’s login username and password (default is often admin/admin).
- Tap Add or Connect.
The app will attempt to connect to your DVR via Dahua’s cloud servers. If successful, your device will appear in the device list.
Test the Connection
Once added, tap on your DVR to view the live feed. You should see video from your cameras. Try panning, zooming, or switching channels to ensure everything works smoothly.
If the connection fails, double-check the Device ID, login credentials, and internet connection. We’ll cover troubleshooting later in this guide.
Step 4: Access Your DVR via Web Browser (Optional)
While the DMSS app is convenient, you might also want to access your DVR from a computer using a web browser. This method is useful for viewing multiple cameras or managing settings remotely.
Log In to the DVR’s Web Interface
Follow these steps:
- Open a web browser on your computer.
- Go to https://www.dahuasecurity.com and click on Support > Remote Access.
- Alternatively, use the direct P2P login page: https://dvr.dahuasecurity.com.
- Enter your DVR’s Device ID, username, and password.
- Click Login.
If successful, you’ll be taken to the DVR’s web interface, where you can view live video, playback recordings, and adjust settings.
Enable ActiveX or Web Plugin (if required)
Some older DVR models may require you to install an ActiveX plugin or web component. If prompted:
- Allow the plugin to install (only from trusted sources).
- Restart the browser if needed.
- Ensure your browser allows pop-ups and scripts from Dahua’s domain.
Note: Modern browsers like Chrome and Firefox may block ActiveX. In such cases, use the DMSS app or SmartPSS desktop software instead.
Step 5: Use SmartPSS Desktop Software (Advanced Option)
For users who prefer a full desktop experience, Dahua’s SmartPSS software offers advanced features like multi-camera viewing, event management, and system configuration.
Download and Install SmartPSS
Here’s how to get started:
- Visit the official Dahua website: https://www.dahuasecurity.com.
- Go to Support > Downloads > Software.
- Download the latest version of SmartPSS for your operating system (Windows or macOS).

Step 6: Secure Your DVR and P2P Connection
While P2P is convenient, it’s important to secure your system to prevent unauthorized access.
Change Default Login Credentials
Never leave your DVR with the default username and password. Change them immediately:
- Go to Main Menu > System > User Management.
- Select the admin account and change the password to a strong, unique one.
- Create separate user accounts with limited permissions if needed.
Enable HTTPS and Disable Unused Services
Enhance security by enabling encrypted connections:
- Go to Network > HTTPS and enable it.
- Disable unused services like Telnet, FTP, or UPnP if not needed.
- Regularly update your DVR’s firmware to patch security vulnerabilities.
