What You’ll Need Before Starting

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

• A Dahua DVR or NVR: This guide applies to most Dahua digital video recorders and network video recorders.
• Ethernet cable: To connect your DVR to your router or network switch.
• A computer or laptop: With a compatible web browser (we’ll cover which ones work best).
• Network access: Your DVR must be connected to the same local network as your computer for initial setup.
• Admin credentials: The default username is usually “admin” and the password is often “admin” or blank—but you should change this during setup for security.
• Dahua SADP Tool (optional but recommended): A free utility from Dahua to discover your DVR on the network and configure IP settings.

Having these ready will make the process smoother and help avoid common setup delays.

Step 1: Connect Your Dahua DVR to the Network

The first step in accessing your Dahua DVR from a browser is ensuring it’s properly connected to your local network.

Connect via Ethernet Cable

Use an Ethernet cable to connect the LAN port on your Dahua DVR to an available port on your router or network switch. This provides a stable wired connection, which is more reliable than Wi-Fi for surveillance systems.

Power On the DVR

Plug in the DVR’s power adapter and turn it on. Wait a minute or two for it to fully boot up. You should see indicator lights on the front or back of the device showing power and network activity.

Check Network Connection

Once powered on, the DVR will attempt to obtain an IP address from your router via DHCP (Dynamic Host Configuration Protocol). Most home routers assign IPs automatically, so your DVR should appear on the network.

If you’re unsure whether it’s connected, check your router’s admin page (usually accessible via 192.168.1.1 or 192.168.0.1) and look for a device named “Dahua” or with a MAC address matching your DVR.

Step 2: Find Your Dahua DVR’s IP Address

To access your DVR from a browser, you need to know its IP address. Here are two reliable methods to find it.

Method 1: Use the Dahua SADP Tool

The SADP (Search Active Devices Protocol) tool is a free utility from Dahua that scans your network for Dahua devices and displays their IP addresses, model numbers, and status.

• Download SADP from the official Dahua website (search “Dahua SADP tool”).
• Install and run the tool on a computer connected to the same network as the DVR.
• The tool will list all Dahua devices on the network. Look for your DVR by model number or MAC address.
• Note the IP address listed (e.g., 192.168.1.108).

This method is fast, accurate, and recommended for first-time setups.

Method 2: Check Your Router’s DHCP Client List

If you can’t use SADP, log into your router’s admin interface:

• Open a browser and enter your router’s IP (commonly 192.168.1.1 or 192.168.0.1).
• Log in with your router credentials (check the router label if you haven’t changed them).
• Navigate to “Connected Devices,” “DHCP Clients,” or “LAN Settings.”
• Look for a device named “Dahua” or with a MAC address matching your DVR.
• Note the assigned IP address.

Once you have the IP address, you’re ready to access the DVR via browser.

Step 3: Access Dahua DVR from Browser (Local Network)

Now that you have the IP address, let’s access your DVR from a web browser on the same network.

Open Your Web Browser

Launch a compatible browser. While modern browsers like Chrome and Edge are preferred, Dahua systems often rely on ActiveX or NPAPI plugins, which are no longer supported in standard Chrome or Firefox. We’ll cover workarounds below.

For now, use one of the following:

• Internet Explorer (IE): Best for older Dahua firmware (Windows only).
• Microsoft Edge in IE Mode: Allows IE compatibility on newer Windows systems.
• Google Chrome with IE Tab extension: Simulates IE within Chrome.

Enter the DVR’s IP Address

In the browser’s address bar, type the IP address of your DVR, followed by the port number if it’s not the default.

For example:

http://192.168.1.108

If your DVR uses a custom port (e.g., 81), include it like this:

http://192.168.1.108:81

Press Enter.

Log In to the DVR

You’ll see a login screen. Enter your admin credentials:

• Username: admin (default)
• Password: admin or leave blank (if never changed)

Important: If this is your first login, the system will prompt you to change the default password. Choose a strong, unique password and save it securely.

After logging in, you may see a prompt to install a web plugin.

Step 4: Install the Dahua Web Plugin

Most Dahua DVRs require a browser plugin to display video streams and control the interface. This plugin is usually called WebComponents or Web Plugin.

Automatic Plugin Installation

When you first access the DVR via browser, you’ll likely see a message like:

> “To view live video, please install the Web Plugin.”

Click the link or button to download and install the plugin. This is typically a small executable file (e.g., WebComponents.exe).

Manual Plugin Installation

If the automatic download doesn’t work:

• Visit the official Dahua support website.
• Search for “WebComponents” or “Dahua Web Plugin.”
• Download the latest version compatible with your DVR model and operating system.
• Run the installer and follow the on-screen instructions.

Browser Compatibility Tips

Due to plugin limitations, here’s how to ensure compatibility:

• Use Internet Explorer (IE 11): Best for older systems. Enable ActiveX controls in IE settings.
• Use Edge in IE Mode: In Edge, go to Settings > Default browser > Allow sites to be reloaded in IE mode. Add your DVR’s IP to the list.
• Use Chrome with IE Tab: Install the “IE Tab” extension from the Chrome Web Store. When accessing the DVR, click the IE Tab icon to load the page in IE mode.

After installing the plugin and configuring your browser, refresh the page. You should now see the Dahua web interface with live video feeds.

Step 5: Configure Remote Access (Over the Internet)

Accessing your DVR from outside your local network requires remote connectivity. Dahua offers two main methods: P2P (Peer-to-Peer) and DDNS (Dynamic DNS).

Method 1: Use Dahua P2P (Recommended)

P2P is the easiest and most secure way to access your DVR remotely. It uses Dahua’s cloud service to connect your device to your browser or mobile app without opening ports on your router.

Enable P2P on Your DVR

• Log in to the DVR via browser (as shown above).
• Go to Configuration > Network > P2P.
• Enable P2P and note the Serial Number (also called Device ID or S/N).
• Save the settings.

Access via Dahua Mobile App or Web Portal

• Download the DMSS (Dahua Mobile Security Surveillance) app on your smartphone.
• Create a Dahua account (or log in if you have one).
• Add your DVR using the serial number.
• You can now view live feeds and playback recordings from anywhere.

For browser access, visit https://dhi-dms.com or https://www.dahuasecurity.com and log in with your Dahua account. Add your device using the serial number.

Method 2: Set Up DDNS (Advanced)

If you prefer not to use P2P, you can set up DDNS to access your DVR via a custom domain name.

Steps to Configure DDNS

• Sign up for a free DDNS service (e.g., No-IP, DynDNS).
• Create a hostname (e.g., mydvr.ddns.net).
• On your DVR, go to Configuration > Network > DDNS.
• Select your DDNS provider, enter your credentials and hostname.
• Save and enable DDNS.

Port Forwarding (Required for DDNS)

To allow external access, you must forward ports on your router:

• Log in to your router’s admin page.
• Go to Port Forwarding or Virtual Server.
• Add a new rule:
  • Service Name: Dahua DVR
  • External Port: 80 (HTTP) or custom port
  • Internal IP: Your DVR’s IP (e.g., 192.168.1.108)
  • Internal Port: 80
  • Protocol: TCP
• Save the rule.

Now, you can access your DVR remotely by entering:

http://mydvr.ddns.net

Warning: Port forwarding exposes your DVR to the internet. Use strong passwords and consider changing the default port for added security.

Step 6: Optimize Browser Settings for Best Performance

To ensure smooth video playback and interface responsiveness, tweak your browser settings.

Enable ActiveX and Plugins

In Internet Explorer or IE mode:

• Go to Tools > Internet Options > Security > Custom Level.
• Enable:
  • ActiveX controls and plug-ins
  • Scripting of Java applets
  • Automatic prompting for ActiveX controls
• Click OK and restart the browser.

Disable Pop-up Blockers

The Dahua interface may open video windows in pop-ups. Disable pop-up blockers for your DVR’s IP address.

Clear Cache and Cookies

If the interface loads slowly or doesn’t update, clear your browser cache and cookies.

Troubleshooting Common Issues

Even with proper setup, you might encounter problems. Here are solutions to the most common issues.

Blank Screen or “Plugin Not Installed”

• Ensure the WebComponents plugin is installed.
• Try a different browser or enable IE mode.
• Run the browser as administrator (right-click > Run as administrator).

“Login Failed” or “Invalid Password”

• Double-check username and password (case-sensitive).
• If you forgot the password, reset the DVR using the reset button (usually on the back) or via SADP tool.

Can’t Access DVR Remotely

• Verify P2P is enabled and the serial number is correct.
• Check your internet connection and firewall settings.
• For DDNS, confirm port forwarding is active and the external IP is reachable.

Video Lag or Poor Quality

• Reduce the stream resolution in DVR settings (e.g., use Substream for remote viewing).
• Ensure a stable internet connection with sufficient upload speed.
• Close other bandwidth-heavy applications.

Browser Crashes or Freezes

• Update your browser and plugin to the latest version.
• Try using a different device or browser.
• Reinstall the WebComponents plugin.
