What You’ll Need Before Starting

Before diving into the setup process, make sure you have the following items ready:

• Dahua DVR (connected to your security cameras)
• Stable internet connection (wired Ethernet is recommended)
• Router with admin access (to configure port forwarding if needed)
• Computer or smartphone (for setup and remote viewing)
• Dahua mobile app (DMSS or Smart PSS) installed on your device
• DVR login credentials (default is usually admin/admin or admin/123456)

Having these ready will ensure a smooth setup process and prevent delays.

Step 1: Connect Your Dahua DVR to the Internet

The first step in accessing your Dahua DVR online is connecting it to your network. Most Dahua DVRs come with an Ethernet port for wired internet connection.

Connect via Ethernet Cable

Use a standard Ethernet cable to connect the DVR’s LAN port to one of the available ports on your router. This provides a stable and fast connection, which is crucial for smooth video streaming.

Check Network Status on the DVR

Once connected, power on the DVR and access the main menu. Navigate to Network > TCP/IP to verify the IP address. The DVR should automatically obtain an IP address via DHCP from your router. You should see an IP like 192.168.1.108 or similar.

Assign a Static IP (Recommended)

To avoid IP changes that can break remote access, assign a static IP to your DVR. In the same TCP/IP settings, switch from DHCP to static and enter an IP address within your router’s range (e.g., 192.168.1.150), along with the subnet mask (255.255.255.0) and gateway (your router’s IP, usually 192.168.1.1).

Step 2: Enable P2P for Easy Remote Access

Dahua’s P2P (Peer-to-Peer) technology is the easiest way to access your DVR online without dealing with complex network settings. It uses a cloud service to connect your device to the DVR securely.

Enable P2P on the DVR

Go to Network > P2P in the DVR menu. Make sure the P2P option is enabled. You’ll see a QR code and a serial number (also called a Device ID or S/N). This information is essential for connecting via the mobile app.

Register Your DVR (Optional but Recommended)

For added security and easier management, register your DVR on Dahua’s cloud platform. Visit dahuasecurity.com and create a free account. Then, log in to the DVR’s web interface and link it to your account under Network > P2P > Cloud.

Test P2P Connection

After enabling P2P, wait a few minutes for the DVR to connect to the cloud. The status should show “Online” or “Connected.” If it shows “Offline,” check your internet connection and ensure the DVR has outbound access to Dahua’s servers (ports 80, 443, and 37777 should be open).

Step 3: Access Dahua DVR Using the Mobile App

The Dahua Mobile Surveillance System (DMSS) app is the most convenient way to view your DVR remotely. It’s available for both iOS and Android devices.

Download and Install the App

Search for “DMSS” in the App Store (iOS) or Google Play Store (Android). Download and install the official app from Dahua Technology.

Add Your DVR Using P2P

Open the app and tap the “+” icon to add a new device. Choose “Scan QR Code” and point your camera at the QR code displayed on your DVR’s P2P menu. Alternatively, manually enter the Device ID (S/N) and device name.

Enter Login Credentials

Input your DVR’s username and password (default is often admin/admin). Tap “Save” and wait for the app to connect. Once connected, you’ll see live video feeds from your cameras.

Customize Viewing Settings

You can switch between cameras, view recordings, adjust image quality, and even control PTZ (Pan-Tilt-Zoom) cameras directly from the app. Enable motion alerts to receive notifications when activity is detected.

Step 4: Access Dahua DVR via Web Browser

If you prefer using a computer, you can access your Dahua DVR through a web browser. This method is useful for system configuration and multi-camera monitoring.

Find the DVR’s IP Address

As mentioned earlier, check the DVR’s network settings to confirm its local IP address (e.g., 192.168.1.150).

Enter the IP in Your Browser

Open a web browser (Chrome, Firefox, Edge) and type the DVR’s IP address into the address bar. Press Enter. You should see the Dahua login page.

Install Web Plugin (If Required)

Some Dahua DVRs require a web plugin for video playback. If prompted, download and install the plugin from the login page. Note: Modern browsers like Chrome may block plugins, so consider using Internet Explorer or enabling compatibility mode.

Log In and Start Viewing

Enter your DVR username and password. Once logged in, you’ll see the live view interface. You can switch cameras, playback recordings, adjust settings, and manage users.

Step 5: Set Up Port Forwarding (Alternative to P2P)

If P2P isn’t working or you prefer a direct connection, you can use port forwarding. This method requires more technical knowledge but gives you full control.

Find Your DVR’s Port Numbers

Go to Network > TCP/IP on the DVR. Note the HTTP port (default is 80) and RTSP port (default is 554). You may also need the server port (default 37777).

Access Your Router’s Admin Panel

Open a browser and enter your router’s IP (usually 192.168.1.1 or 192.168.0.1). Log in with your router’s admin credentials.

Set Up Port Forwarding Rules

Navigate to Port Forwarding or Virtual Server section. Create a new rule:

• Service Name: Dahua DVR
• External Port: 80 (or a custom port like 8080)
• Internal IP: Your DVR’s static IP (e.g., 192.168.1.150)
• Internal Port: 80
• Protocol: TCP

Repeat for other ports if needed (e.g., 37777 for remote access).

Find Your Public IP Address

Visit a site like whatismyipaddress.com to find your public IP. This is what you’ll use to access the DVR remotely.

Access DVR Remotely via Public IP

On an external network (e.g., mobile data), open a browser and enter: http://[your-public-ip]:8080 (replace 8080 with your external port). Log in to view your DVR.

Step 6: Use iVMS-4200 for Advanced Management

For professional users, Dahua’s iVMS-4200 software offers advanced features like multi-device management, alarm handling, and video analytics.

Download and Install iVMS-4200

Visit the Dahua website and download the iVMS-4200 client for Windows. Install it on your computer.

Add Your DVR

Open the software and click “Add Device.” Enter the DVR’s IP, port, username, and password. Choose “TCP” as the connection type.

Enable Remote Access

Once added, right-click the device and select “Remote Configuration.” You can adjust settings, view live feeds, and playback recordings.

Set Up Remote Viewing

Use the software’s remote access feature to connect from outside your network. Ensure port forwarding or P2P is properly configured.

Step 7: Secure Your Dahua DVR

Security is critical when accessing your DVR online. Default settings are vulnerable to hacking.

Change Default Passwords

Immediately change the default admin password to a strong, unique one. Use a mix of letters, numbers, and symbols.

Enable HTTPS and Encryption

Go to Network > HTTPS and enable SSL encryption. This protects data transmitted between your device and the DVR.

Disable Unused Services

Turn off services like Telnet and FTP if not needed. These can be exploited by attackers.

Enable IP Filtering

Restrict access to specific IP addresses under Network > IP Filter. Only allow trusted devices to connect.

Update Firmware Regularly

Check for firmware updates in System > Maintenance > Upgrade. Updated firmware fixes bugs and improves security.

Troubleshooting Common Issues

Even with proper setup, you might encounter problems. Here’s how to fix the most common ones.

Can’t Connect via P2P

• Ensure P2P is enabled on the DVR.
• Check internet connection and firewall settings.
• Verify the Device ID is correct in the app.
• Restart the DVR and router.

Web Browser Shows Blank Screen

• Install the required web plugin.
• Try a different browser (Internet Explorer works best for older DVRs).
• Disable pop-up blockers and enable ActiveX.

Port Forwarding Not Working

• Confirm the DVR has a static IP.
• Double-check port numbers and forwarding rules.
• Test with a different external port (e.g., 8080 instead of 80).
• Contact your ISP—some block common ports.

Slow or Laggy Video

• Reduce video resolution or frame rate in DVR settings.
• Use a wired connection instead of Wi-Fi.
• Close other apps using bandwidth.

App Says “Device Offline”

• Check if the DVR is powered on and connected to the internet.
