Let’s get started!

What You’ll Need

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

• A Dahua DVR (any model with Ethernet port)
• An Ethernet cable (Cat5e or Cat6 recommended)
• A router or network switch
• A computer or laptop connected to the same network
• Access to the DVR’s user interface (via monitor and mouse, or remotely)
• Dahua software (optional but helpful): ConfigTool, Smart PSS, or DMSS mobile app

Having these items ready will make the process smooth and efficient.

Step 1: Physically Connect the Dahua DVR to Your Network

The first step is establishing a physical connection between your Dahua DVR and your local network.

Locate the Ethernet Port

On the back panel of your Dahua DVR, you’ll find an RJ45 Ethernet port—usually labeled “LAN” or “NET.” This is where you’ll plug in your Ethernet cable.

Connect the Cable

Take one end of the Ethernet cable and plug it into the DVR’s LAN port. Plug the other end into an available port on your router or network switch. Make sure the connection is secure.

Tip: Use a high-quality cable and avoid running it near power lines to prevent interference.

Power On the DVR

If your DVR isn’t already powered on, plug it in and turn it on. Wait a minute or two for it to boot up completely. You should see lights on the Ethernet port indicating a connection (usually a green or amber LED).

Step 2: Access the DVR’s Network Settings

Now that the DVR is connected, you need to configure its network settings. You can do this directly on the DVR using a monitor and mouse, or remotely if you’ve previously set it up.

Connect a Monitor and Mouse

If you haven’t already, connect an HDMI or VGA monitor to the DVR and plug in a USB mouse. This gives you direct access to the DVR’s graphical user interface (GUI).

Log In to the DVR

On the main screen, click the “Menu” button (usually in the lower-right corner). Enter your username and password. The default is often:

• Username: admin
• Password: admin or 123456

Note: Always change the default password after initial setup for security.

Navigate to Network Settings

Once logged in, go to:

Main Menu > Network > TCP/IP

Here, you’ll see the current network configuration. By default, the DVR may be set to obtain an IP address automatically (DHCP).

Step 3: Assign a Static IP Address

Using a static (fixed) IP address is highly recommended. This ensures your DVR always has the same address on the network, making it easier to access and reducing the risk of connection drops.

Why Use a Static IP?

When a device uses DHCP, your router assigns it an IP address that can change over time. If the IP changes, you won’t be able to connect unless you rediscover it. A static IP avoids this problem.

Find Your Router’s IP Range

Open a command prompt on your computer (Windows: press Win + R, type cmd, press Enter). Type:

ipconfig

Look for the “Default Gateway” under your active network adapter. This is your router’s IP (e.g., 192.168.1.1). Your DVR’s IP should be in the same range (e.g., 192.168.1.x).

Set a Static IP on the DVR

Back in the DVR’s network settings:

• Set IP Address to something like 192.168.1.100 (avoid .1, which is usually the router)
• Set Subnet Mask to 255.255.255.0
• Set Default Gateway to your router’s IP (e.g., 192.168.1.1)
• Set Preferred DNS to your router’s IP or a public DNS like 8.8.8.8 (Google)

Example: If your router is 192.168.1.1, set the DVR to 192.168.1.100.

Save and Reboot

Click “Save” or “Apply.” The DVR may restart to apply the new settings. Wait for it to come back online.

Step 4: Verify the Connection

Now that the DVR has a static IP, let’s make sure your computer can reach it.

Ping the DVR

On your computer, open the command prompt again and type:

ping 192.168.1.100

(Replace with your DVR’s actual IP.)

If you see replies like “Reply from 192.168.1.100,” the connection is working. If you get “Request timed out,” there’s a problem.

Troubleshoot Ping Failures

• Double-check the IP address and cable connections
• Ensure both devices are on the same network
• Restart the DVR and router
• Try a different Ethernet cable or port

Step 5: Access the DVR via Web Browser

Once the network connection is confirmed, you can access the DVR’s interface through a web browser.

Open a Browser

Launch Chrome, Firefox, or Edge. In the address bar, type:

http://192.168.1.100

(Use your DVR’s IP.)

Log In

You’ll see a login page. Enter your DVR username and password (same as before).

Note: Some browsers may show a security warning. Click “Advanced” and proceed—this is normal for local devices.

Install ActiveX or Web Plugin (if prompted)

Older Dahua DVRs may require an ActiveX plugin for full functionality. Follow the on-screen instructions to install it. Modern systems often use HTML5, which works without plugins.

View Live Feed

Once logged in, you should see the live video feed from your cameras. You can switch channels, playback recordings, and adjust settings.

Step 6: Use Dahua ConfigTool for Easy Discovery

If you’re having trouble finding the DVR’s IP, Dahua’s ConfigTool software can help.

Download and Install ConfigTool

Go to the official Dahua website and download ConfigTool for your operating system. Install it on your computer.

Launch ConfigTool

Open the software. It will automatically scan your network for Dahua devices.

Find Your DVR

Look for your DVR in the list. It should show the model, IP address, MAC address, and status.

Modify Settings (Optional)

You can change the IP address, password, or network settings directly from ConfigTool. Right-click the device and select “Modify IP” or “Login.”

Test Connection

Click “Test” to verify connectivity. If successful, you can now access the DVR via the new IP.

Step 7: Enable Remote Access and Services

To get the most out of your DVR, enable key network services.

Enable HTTP Service

In the DVR’s network settings, go to:

Main Menu > Network > Connection

Make sure “HTTP Service” is enabled. This allows web browser access.

Enable RTSP

RTSP (Real-Time Streaming Protocol) lets you stream video to third-party apps or VLC media player.

Go to:

Main Menu > Network > RTSP

Enable RTSP and note the port (default is 554).

Enable ONVIF

ONVIF allows integration with other security systems and software.

Go to:

Main Menu > Network > ONVIF

Enable ONVIF and set a username/password if required.

Enable FTP (Optional)

If you want to upload recordings to an FTP server, enable FTP under:

Main Menu > Storage > FTP

Enter your FTP server details.

Step 8: Access DVR from Mobile Devices

You can also monitor your Dahua DVR on smartphones and tablets.

Download DMSS App

Search for “DMSS” in the App Store (iOS) or Google Play (Android). Install the app.

Add Your DVR

Open DMSS and tap the “+” icon. Choose “Manual Add.”

Enter:
