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 with internet connectivity: Most modern Dahua DVRs support remote access, but older models may require firmware updates.
• An active internet connection: Your DVR must be connected to a router via Ethernet cable. Wi-Fi is not recommended for DVRs due to reliability issues.
• A router with admin access: You’ll need to log in to your router to configure settings like port forwarding or enable UPnP.
• A smartphone, tablet, or computer: To access your DVR remotely, you’ll need a device to run the Dahua app or software.
• The Dahua mobile app (DMSS) or PC software (SmartPSS): Download these free tools from the official Dahua website or app stores.
• Your DVR’s serial number or QR code: Found on the device or in the user manual. This is required for P2P setup.

Once you’ve gathered everything, you’re ready to begin.

Step 1: Connect Your Dahua DVR to the Internet

The first step in enabling remote viewing is ensuring your DVR is connected to the internet. Here’s how:

Connect via Ethernet Cable

Use an Ethernet cable to connect your Dahua DVR to one of the LAN ports on your router. Avoid using Wi-Fi adapters unless absolutely necessary—wired connections are more stable and secure.

Power On the DVR

Plug in your DVR and monitor. Wait for it to boot up completely. You should see the main menu or live camera feeds on the screen.

Check Network Status

Navigate to the DVR’s main menu. Go to Network > TCP/IP. Here, you’ll see the current IP address assigned to the DVR by your router (usually something like 192.168.1.100).

If the IP address starts with 169.254, it means the DVR failed to get an IP from the router. Check your Ethernet connection and router settings.

Set a Static IP Address (Recommended)

To avoid connection issues, assign a static IP to your DVR. This ensures the IP doesn’t change if the router reboots.

• In the TCP/IP settings, switch from “DHCP” to “Manual.”
• Enter an IP address within your router’s range (e.g., 192.168.1.200).
• Set the subnet mask to 255.255.255.0.
• Enter your router’s IP as the gateway (usually 192.168.1.1).
• Save the settings and restart the DVR if prompted.

Now your DVR has a fixed IP address, making remote access more reliable.

Step 2: Enable P2P for Easy Remote Access

Dahua’s P2P (Peer-to-Peer) technology is the easiest way to set up remote viewing. It eliminates the need for complex port forwarding and dynamic DNS. Here’s how to enable it:

Access the DVR’s Web Interface

Open a web browser on a computer connected to the same network as the DVR. Type the DVR’s IP address into the address bar and press Enter.

Log in using the admin username and password (default is usually “admin” and “admin” or “123456”—change this immediately for security).

Enable P2P Service

Go to Configuration > Network > P2P.

• Check the box to Enable P2P.
• Note the Serial Number or scan the QR code displayed on the screen. You’ll need this to add the DVR to your mobile app.
• Save the settings.

Download and Install the DMSS App

On your smartphone or tablet, download the DMSS app from the Apple App Store or Google Play Store. This is Dahua’s official mobile app for remote viewing.

Add Your DVR Using P2P

Open the DMSS app and tap the “+” icon to add a new device.

• Select Add via UID.
• Enter the DVR’s serial number or scan the QR code from the DVR’s P2P settings.
• Enter a name for the device (e.g., “Home DVR”).
• Tap Save.

The app will connect to your DVR within seconds. You should now see live camera feeds on your phone.

Step 3: Set Up Remote Viewing on a Computer

If you prefer using a desktop or laptop, Dahua’s SmartPSS software offers full remote access with advanced features like playback, alarm management, and device configuration.

Download SmartPSS

Visit the official Dahua website and download SmartPSS for your operating system (Windows or macOS). Install it on your computer.

Add Your DVR via P2P

Open SmartPSS and click Device Management.

• Click the “+” icon and select Add Device.
• Choose P2P as the connection type.
• Enter the DVR’s serial number and a device name.
• Click OK to add the device.

Log In and View Cameras

Double-click the added device to log in. Use your DVR’s admin credentials.

Once logged in, you’ll see all connected cameras. You can view live feeds, playback recordings, and adjust settings remotely.

Step 4: Configure Port Forwarding (Alternative Method)

If P2P isn’t working or your DVR doesn’t support it, you can set up remote access manually using port forwarding. This method requires more technical knowledge but gives you full control.

Find Your DVR’s Port Numbers

In the DVR’s network settings, note the following default ports:

• HTTP Port: 80 (for web access)
• Server Port: 37777 (for data transfer)
• RTSP Port: 554 (for video streaming)

You can change these ports if needed, but make sure they’re not blocked by your ISP or firewall.

Log In to Your Router

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

Set Up Port Forwarding Rules

Navigate to the Port Forwarding or Virtual Server section (the exact name varies by router brand).

Create a new rule for each port:

• Service Name: Dahua_HTTP
• External Port: 80
• Internal IP: Your DVR’s static IP (e.g., 192.168.1.200)
• Internal Port: 80
• Protocol: TCP

Repeat for ports 37777 and 554.

Find Your Public IP Address

Go to a site like whatismyip.com to find your public IP address. This is the address you’ll use to access your DVR remotely.

Access DVR Remotely via Web Browser

On any device outside your home network, open a browser and type:

http://[Your_Public_IP]:80

Replace [Your_Public_IP] with your actual public IP. Log in with your DVR credentials to view the interface.

Add DVR to DMSS Using IP

In the DMSS app, tap “+” and select Add via IP/Domain.

• Enter your public IP address.
• Set the port to 37777.
• Enter your login credentials.
• Save and connect.

Step 5: Secure Your Dahua DVR

Remote access increases convenience but also security risks. Follow these best practices to protect your system:

Change Default Passwords

The default admin password is a major security risk. Change it immediately:

• Go to System > User Management.
• Select the admin account and click Modify.
• Enter a strong password (8+ characters, mix of letters, numbers, and symbols).
• Save the changes.

Enable HTTPS and Disable Telnet

In the network settings, enable HTTPS for encrypted connections and disable Telnet to prevent unauthorized access.

Update Firmware Regularly

Check for firmware updates on the Dahua website. Updated firmware fixes bugs and improves security.

Use a Firewall

Configure your router’s firewall to block unnecessary incoming traffic. Only allow ports 80, 37777, and 554 if using port forwarding.

Troubleshooting Common Issues

Even with careful setup, you might run into problems. Here are solutions to common issues:

“Connection Timed Out” or “Unable to Connect”

• Check that the DVR is powered on and connected to the network.
• Verify the IP address and port numbers.
• Ensure your public IP hasn’t changed (use a dynamic DNS service if needed).
• Restart the DVR and router.

“Invalid Username or Password”

• Double-check your login credentials.
• Reset the password via the DVR’s local interface if forgotten.
• Ensure Caps Lock is off.

P2P Not Working

• Confirm P2P is enabled on the DVR.
• Check that the serial number is entered correctly in the app.
• Ensure your router supports UPnP and it’s enabled.
• Try restarting the DVR and app.

Slow or Laggy Video

• Reduce the video resolution or frame rate in the DVR settings.
• Use a wired connection instead of Wi-Fi for the viewing device.
• Check your internet upload speed—remote viewing requires at least 2 Mbps upload.

Conclusion

Configuring your Dahua DVR for remote viewing opens up a world of convenience and peace of mind. Whether you use the simple P2P method or set up port forwarding for more control, you can now monitor your property from anywhere.

We’ve covered everything from connecting your DVR to the internet, enabling P2P, using the DMSS app and SmartPSS software, securing your system, and troubleshooting common issues. With these steps, you’re well-equipped to enjoy seamless remote access to your security cameras.
