Why Make Your Dahua DVR Online?

Before diving into the setup, let’s talk about why remote access matters. A Dahua DVR isn’t just for local monitoring. When connected to the internet, it becomes a powerful tool for real-time security and peace of mind.

Imagine getting a motion alert on your phone while you’re at the grocery store. You open the app, check the live feed, and see that it’s just your cat knocking over a plant. Or maybe you’re traveling and want to peek in on your home or business to make sure everything’s secure. With your Dahua DVR online, you can do all that—and more.

Remote access also lets you:

• Review recorded footage from anywhere
• Receive instant push notifications for motion or alarms
• Share camera views with family members or employees
• Monitor multiple locations from one device

Whether you’re protecting your home, office, or retail space, going online with your Dahua DVR adds a whole new level of convenience and control.

What You’ll Need Before You Begin

Before we start configuring your DVR, make sure you have the following:

• A Dahua DVR with network capability: Most modern Dahua DVRs support Ethernet and internet connectivity. Check the back of your unit for an RJ45 Ethernet port.
• A stable internet connection: A wired broadband connection (DSL, cable, or fiber) is recommended. Wi-Fi is not ideal for DVRs due to latency and reliability issues.
• A router with internet access: Your DVR must be connected to a router that’s already online.
• An Ethernet cable: To connect your DVR directly to the router.
• A computer or smartphone: For initial setup and remote access.
• Dahua mobile app (DMSS or SmartPSS): Download the free app from the App Store or Google Play.
• Your DVR’s serial number or QR code: Found on the device or packaging—needed for P2P setup.

Once you’ve confirmed you have everything, let’s move on to the setup process.

Step 1: Connect Your Dahua DVR to the Network

The first step to making your Dahua DVR online is physically connecting it to your network.

Connect via Ethernet Cable

1. Power off your DVR and router (optional but recommended for safety).
2. Use an Ethernet cable to connect the DVR’s LAN port to one of the LAN ports on your router.
3. Power both devices back on.
4. Wait 1–2 minutes for the DVR to boot up and establish a connection.

You should see network activity lights on both the DVR and router, indicating a successful link.

Verify Network Connection

To confirm your DVR is online:

1. Access the DVR’s local interface using a monitor and mouse connected directly to the DVR.
2. Go to Main Menu > Network > TCP/IP.
3. Check that the DVR has received an IP address from your router (usually in the format 192.168.x.x).
4. If no IP appears, ensure your router’s DHCP is enabled and try reseating the Ethernet cable.

At this point, your DVR is on your local network—but not yet accessible from the internet. That’s what we’ll fix next.

Step 2: Assign a Static IP Address to Your DVR

To ensure reliable remote access, your DVR should have a static (unchanging) IP address. If it keeps getting a new IP from the router, your remote connection may break.

Why Use a Static IP?

Routers assign temporary IP addresses via DHCP. These can change after a reboot or lease expiration. A static IP prevents this, making it easier to connect remotely.

How to Set a Static IP on Dahua DVR

1. Go to Main Menu > Network > TCP/IP.
2. Note the current IP address, subnet mask, and gateway (usually 192.168.1.1).
3. Change the configuration from “DHCP” to “Manual”.
4. Enter a static IP address within your router’s range (e.g., 192.168.1.100).
5. Set the subnet mask (usually 255.255.255.0) and gateway (your router’s IP).
6. Save the settings and reboot the DVR if prompted.

Tip: Avoid using IPs already assigned to other devices. Check your router’s connected devices list to find available addresses.

Step 3: Enable P2P (Plug-and-Play) for Easy Remote Access

The easiest way to make your Dahua DVR online is by using Dahua’s P2P service. This method requires no port forwarding or complex network knowledge.

What Is P2P?

P2P (Peer-to-Peer) allows your DVR to connect to Dahua’s cloud servers, enabling remote access through a simple QR code scan. It’s secure, fast, and works on most Dahua models.

How to Enable P2P on Your Dahua DVR

1. Go to Main Menu > Network > P2P.
2. Enable the P2P function by toggling it “On”.
3. Note the Serial Number displayed on the screen—you’ll need this for app setup.
4. Download and open the DMSS app (Dahua Mobile Surveillance System) on your smartphone.
5. Tap the “+” icon to add a device.
6. Choose “Scan QR Code” and point your camera at the QR code on the DVR screen (or enter the serial number manually).
7. Enter a name for your device (e.g., “Home DVR”) and your DVR login credentials (default is usually admin/admin).
8. Tap “Save” and wait for the connection.

Once connected, you should see live camera feeds in the app. You can now view your DVR from anywhere with internet access.

Pro Tip: If the QR code doesn’t appear, ensure P2P is enabled and your DVR has internet access. Some older models may require a firmware update.

Step 4: Set Up Port Forwarding (Alternative to P2P)

If P2P isn’t working or your DVR doesn’t support it, you can manually configure port forwarding. This method gives you direct access but requires router configuration.

What Is Port Forwarding?

Port forwarding tells your router to send incoming internet traffic on specific ports directly to your DVR. This allows external devices to connect to your DVR using your public IP address.

Ports to Forward for Dahua DVR

• HTTP Port: 80 (for web access)
• RTSP Port: 554 (for video streaming)
• Server Port: 37777 (used by Dahua software)
• Mobile Port: 37788 (for mobile apps)

Note: Some ISPs block port 80. If so, use an alternative like 8080.

How to Configure Port Forwarding

1. Log in to your router’s admin panel (usually by typing 192.168.1.1 in a browser).
2. Find the Port Forwarding or Virtual Server section (location varies by brand).
3. Create a new rule with the following details:
   • Service Name: Dahua_DVR
   • External Port: 80 (or 8080)
   • Internal IP: Your DVR’s static IP (e.g., 192.168.1.100)
   • Internal Port: 80
   • Protocol: TCP
4. Add additional rules for ports 554, 37777, and 37788 using the same internal IP.
5. Save the settings and reboot the router if needed.

Test Remote Access via Web Browser

1. Find your public IP address by searching “what is my IP” on Google.
2. Open a browser and enter: http://[your-public-ip]:80 (replace with your actual IP).
3. Log in with your DVR credentials.
4. If the login page loads, port forwarding is working!

Warning: Exposing your DVR to the internet increases security risks. Always use strong passwords and consider using a non-standard port.

Step 5: Use Mobile Apps and Desktop Software

Once your Dahua DVR is online, you can access it through various platforms.

Mobile Access with DMSS App

The DMSS app is the easiest way to view your cameras on the go.

1. Go to Main Menu > System > User Management.
2. Select the admin account and click “Modify”.
3. Enter a strong password (12+ characters, mix of letters, numbers, symbols).
4. Save the changes.

Enable HTTPS and Disable Telnet

1. Go to Network > HTTPS and enable it for encrypted web access.
2. Disable Telnet and FTP services if not needed (found under Network settings).

Update Firmware Regularly

Outdated firmware can have security flaws.

1. Visit Dahua’s official support site.
2. Enter your DVR model and download the latest firmware.
3. Go to System > Maintenance > Upgrade and upload the file.
4. Reboot the DVR after update.
