Before you start, it’s crucial to confirm whether your Dahua DVR can actually connect to WiFi. Not all models have built-in wireless capabilities. Some older or budget models require a USB WiFi adapter, while others don’t support wireless at all.
How to Identify WiFi-Compatible Dahua DVRs
Look at the back or side of your DVR unit. If you see a small USB port labeled “WiFi” or “Wireless,” there’s a good chance it supports a USB WiFi adapter. Newer models like the Dahua XVR5104HS, XVR5108HS, or any model in the Pro or Ultra series often include built-in WiFi or adapter support.
You can also check the model number on the label (usually on the bottom or back) and search it on Dahua’s official website. Look for specifications that mention “WiFi,” “Wireless,” or “802.11b/g/n.”
Using a USB WiFi Adapter
If your DVR doesn’t have built-in WiFi, you may still be able to add wireless functionality using a compatible USB WiFi adapter. Dahua recommends specific models, such as the Dahua WIFI-USB200 or WIFI-USB300. These are plug-and-play and designed to work seamlessly with Dahua systems.
Avoid using generic or third-party adapters unless they’re explicitly listed as compatible. Many won’t work due to driver issues or lack of support in the DVR’s firmware.
Important Note on WiFi Standards
Most Dahua DVRs that support WiFi only work on the 2.4 GHz frequency band. They do not support 5 GHz networks. This is important because many modern routers broadcast both bands, and your DVR might fail to connect if it’s trying to join a 5 GHz network.
Make sure your router’s 2.4 GHz network is enabled and broadcasting. If your router combines both bands under one name (called “band steering”), you may need to temporarily split them in your router settings to ensure the DVR connects to the correct band.
Step 2: Prepare Your Network and Equipment
Now that you’ve confirmed your DVR can connect to WiFi, it’s time to get your network ready. A stable and secure network is essential for reliable video streaming and remote access.
Gather Your Tools
You’ll need:
– Your Dahua DVR and power supply
– A monitor or TV with HDMI/VGA input (for initial setup)
– An Ethernet cable (for wired setup)
– A compatible USB WiFi adapter (if required)
– Your WiFi network name (SSID) and password
– A smartphone or tablet (for app setup)
Ensure Strong WiFi Signal
Place your DVR in a location where it can receive a strong WiFi signal. Walls, metal objects, and appliances like microwaves can interfere with the signal. If your DVR will be in a basement or far from the router, consider using a WiFi extender or moving the router closer.
You can test signal strength using your phone. Stand near where the DVR will be installed and check the WiFi bars. If it’s weak (1–2 bars), you may experience lag or disconnections.
Use a Wired Connection for Initial Setup
Even though your goal is WiFi, it’s best to connect your DVR to the router using an Ethernet cable during setup. Wired connections are more stable and reduce the risk of configuration errors.
Plug one end of the Ethernet cable into the DVR’s LAN port and the other into an available port on your router. Power on the DVR and wait for it to boot up.
Step 3: Access the DVR’s Web Interface or Local Menu
To configure WiFi settings, you’ll need to access the DVR’s interface. You can do this in two ways: through the local menu on a connected monitor or via a web browser on a computer.
Option 1: Using the Local Menu (Recommended for Beginners)
1. Connect a monitor or TV to the DVR using an HDMI or VGA cable.
2. Power on the DVR and wait for the login screen to appear.
3. Log in using the default credentials (usually admin/admin or admin/123456). Change these immediately after setup for security.
4. Navigate to Main Menu > Network > TCP/IP.
5. Make sure the IP address is set to “Obtain an IP address automatically (DHCP)” so it gets an address from your router.
Option 2: Using a Web Browser
1. On a computer connected to the same network, open a web browser.
2. Type the DVR’s IP address into the address bar (e.g., 192.168.1.108). You can find this in the local menu under Network settings.
3. Log in with your admin credentials.
4. Go to Configuration > Network > TCP/IP to verify the IP settings.
Once you’re in, you’re ready to configure WiFi.
Step 4: Configure WiFi Settings on Your Dahua DVR
Now comes the core part: setting up the wireless connection. The steps may vary slightly depending on your DVR model and firmware version, but the general process is the same.
Enable Wireless Function
1. In the DVR menu, go to Main Menu > Network > Wireless (or WiFi Settings).
2. Toggle the wireless function to “Enable.”
3. If using a USB adapter, make sure it’s plugged in. The DVR should detect it automatically.
Scan for Available Networks
1. Click Search or Scan to find nearby WiFi networks.
2. Wait for the list to populate. It may take 10–30 seconds.
3. Select your 2.4 GHz WiFi network from the list. Do not select a 5 GHz network.
Enter WiFi Password
1. Type your WiFi password carefully. The field is case-sensitive.
2. Choose the encryption type (usually WPA2-PSK is recommended for security).
3. Click Connect or Apply.
Wait for Connection
The DVR will attempt to connect to the network. This can take 30 seconds to 2 minutes. You’ll see a status message like “Connecting…” or “Connected.”
If successful, the DVR will obtain an IP address from your router via DHCP. You can verify this under Network > TCP/IP—the IP should now be assigned by the router (e.g., 192.168.1.110).
Optional: Set a Static IP (Advanced)
For more reliable remote access, you may want to assign a static IP to your DVR. This prevents the IP from changing if the router reboots.
1. In the TCP/IP settings, change from “DHCP” to “Static.”
2. Enter an IP address within your router’s range (e.g., 192.168.1.150).
3. Set the subnet mask (usually 255.255.255.0).
4. Enter your router’s IP as the gateway (e.g., 192.168.1.1).
5. Save the settings.
Step 5: Test the WiFi Connection
After configuring WiFi, it’s important to test the connection to ensure everything is working.
Check Network Status
Go back to Network > TCP/IP and confirm the DVR has an IP address and shows “Connected” under wireless status.
Ping the DVR
On a computer connected to the same network, open Command Prompt (Windows) or Terminal (Mac) and type:
ping [DVR_IP_ADDRESS]
If you get replies, the connection is working.
Disconnect Ethernet Cable
Once WiFi is confirmed working, you can safely unplug the Ethernet cable. The DVR should stay connected wirelessly.
Monitor Signal Strength
Some Dahua DVRs display WiFi signal strength in the menu. Look for a signal icon or percentage. If it’s low, consider relocating the DVR or using a WiFi extender.
Step 6: Set Up Remote Access with Dahua Apps
Now that your DVR is online, you can access it remotely using Dahua’s mobile and desktop apps.
Download the DMSS App
DMSS (Dahua Mobile Surveillance System) is the official app for smartphones. It’s available for free on the Apple App Store and Google Play.
Add Your DVR to the App
1. Open DMSS and tap the “+” icon to add a device.
