  • Works on All Networks: P2P functions over home Wi-Fi, cellular data, and office networks without router configuration.
  • Secure Connection: Dahua uses encrypted tunnels for P2P, ensuring your video feed stays private and protected from hackers.
  • Compatible Devices: Most Dahua DVRs and NVRs made after 2015 support P2P, including models like XVR5104HS, DHI-XVR5108HS, and more.
  • Troubleshooting Tips: If P2P fails, check internet stability, firmware updates, and app permissions to resolve common issues quickly.

Before diving into the setup, let’s clarify what P2P means in the context of Dahua DVRs.

P2P stands for Peer-to-Peer, a technology that allows two devices—like your DVR and smartphone—to connect directly over the internet without relying on a central server. Unlike older methods that require opening ports on your router (which can be a security risk), P2P uses encrypted tunnels to establish a secure connection.

Here’s why P2P is a game-changer:

  • No Port Forwarding: You don’t need to log into your router or configure complex settings.
  • Works with Dynamic IPs: Most home internet connections use dynamic IP addresses that change periodically. P2P handles this automatically.
  • Easy Setup: Just scan a QR code or enter a serial number—no technical expertise required.
  • Secure and Private: Dahua’s P2P system uses end-to-end encryption, so your video feed stays protected.
  • Cross-Platform Access: View your cameras on Android, iOS, Windows, or Mac devices.

In short, P2P makes remote monitoring simple, safe, and accessible to everyone.

Prerequisites: What You’ll Need

Before enabling P2P, make sure you have the following:

1. A Compatible Dahua DVR or NVR

Most Dahua DVRs and NVRs manufactured after 2015 support P2P. Check your model number—common ones include:

  • DHI-XVR5104HS
  • DHI-XVR5108HS
  • DHI-XVR7108HS
  • DHI-HCVR5104HS-S3

If you’re unsure, look for “P2P” or “Cloud” in the product description or user manual.

2. Stable Internet Connection

Your DVR must be connected to the internet via Ethernet (recommended) or Wi-Fi (if supported). A minimum upload speed of 1 Mbps is recommended for smooth video streaming.

3. Dahua Mobile App (DMSS or SmartPSS)

Download the official app:

  • DMSS (Dahua Mobile Surveillance System): Available on Google Play and Apple App Store. Best for mobile viewing.
  • SmartPSS: Desktop software for Windows. Great for managing multiple devices.

4. DVR Serial Number

You’ll need this to add the device to the app. Find it on:

  • The DVR’s label (usually on the back or bottom)
  • The packaging box
  • The DVR’s web interface (Settings > System > Information)

The serial number typically starts with “DH” or “DHI” and is 16–20 characters long.

5. Admin Access to the DVR

You must log in as an administrator to enable P2P in the settings.

Step 1: Connect Your Dahua DVR to the Internet

The first step is ensuring your DVR has internet access.

Option A: Wired Ethernet Connection (Recommended)

  1. Use an Ethernet cable to connect the DVR’s LAN port to your router or modem.
  2. Power on the DVR and wait for it to boot up (usually 1–2 minutes).
  3. The DVR should automatically obtain an IP address via DHCP.

Option B: Wi-Fi Connection (If Supported)

  1. Go to the DVR’s main menu (press Menu on the remote or right-click on the screen).
  2. Navigate to Network > Wi-Fi Settings.
  3. Select your Wi-Fi network and enter the password.
  4. Save and wait for the connection to establish.

Tip: Wired connections are more stable and faster. Use Wi-Fi only if Ethernet isn’t possible.

Step 2: Access the DVR’s Web Interface

To enable P2P, you’ll need to log into the DVR’s settings via a web browser.

Find the DVR’s IP Address

  1. On the DVR screen, go to Main Menu > Network > TCP/IP.
  2. Note the IP address (e.g., 192.168.1.108).
  3. Alternatively, use the Dahua Config Tool (download from Dahua’s website) to scan your network and find the DVR.

Log In via Web Browser

  1. Open Chrome, Firefox, or Edge on a computer connected to the same network.
  2. Type the DVR’s IP address into the address bar and press Enter.
  3. Log in with your admin username and password (default is often “admin” and “admin” or “123456”).

Note: If you’ve changed the default password, use your custom login.

Step 3: Enable P2P in Dahua DVR Settings

Now it’s time to turn on P2P functionality.

Navigate to P2P Settings

  1. In the web interface, go to Configuration > Network > P2P.
  2. You’ll see a toggle or checkbox labeled “Enable P2P” or “Cloud Service.”
  3. Check the box to enable P2P.
  4. Click Save or Apply.

Verify P2P Status

  1. Look for a status message like “Online” or “Connected.”
  2. If it says “Offline,” check your internet connection or restart the DVR.

Pro Tip: Some newer Dahua models auto-enable P2P. If you don’t see the option, your DVR may already have it active.

Step 4: Download and Set Up the Dahua Mobile App

Now that P2P is enabled, let’s connect your DVR to your phone.

Download DMSS

  1. Open the App Store (iOS) or Google Play (Android).
  2. Search for “DMSS” or “Dahua Mobile.”
  3. Download and install the official app by Dahua Technology.

Create a Dahua Account (Optional but Recommended)

  1. Open the app and tap “Register” or “Sign Up.”
  2. Enter your email, create a password, and verify your account.
  3. This account lets you manage multiple devices and receive cloud alerts.

Note: You can use the app without an account, but registration unlocks extra features.

Step 5: Add Your DVR Using P2P

This is the easiest part—adding your DVR with just the serial number.

Method 1: Add via Serial Number

  1. Open DMSS and tap the “+” or “Add Device” button.
  2. Select “P2P” as the connection type.
  3. Enter your DVR’s serial number (found on the label or in the web interface).
  4. Tap “Next.”
  5. The app will search for the device. If found, it will prompt you to enter the DVR’s admin password.
  6. Enter the password and tap “Save.”

Method 2: Scan QR Code (Faster)

  1. In the DVR’s web interface, go to Configuration > Network > P2P.
  2. Look for a QR code labeled “Scan to Add Device.”
  3. In DMSS, tap “Scan QR Code” and point your phone at the screen.
  4. The app will automatically detect the DVR and prompt for the password.
  5. Enter the password and save.

Tip: The QR code method is faster and reduces typing errors.

Step 6: Test Remote Access

Now let’s make sure everything works.

View Live Video

  1. In DMSS, tap your DVR name to open the live view.
  2. You should see video from your cameras.
  3. Swipe to switch between channels.

Test Playback and Alerts

  1. Tap the playback icon to view recorded footage.
  2. Enable motion detection alerts in the DVR settings to receive push notifications.

Try from Outside Your Network

  1. Turn off your phone’s Wi-Fi and use cellular data.
  2. Open DMSS and check if you can still view the cameras.
  3. If yes, P2P is working correctly!

Troubleshooting Common P2P Issues

Even with the best setup, you might run into problems. Here’s how to fix them.

P2P Shows “Offline” in the App

  • Check Internet: Ensure the DVR has a stable connection. Restart the router if needed.
  • Verify P2P is Enabled: Double-check the DVR’s P2P settings.
  • Update Firmware: Outdated firmware can break P2P. Visit Dahua’s support site to download the latest version.

“Device Not Found” Error

  • Confirm Serial Number: Make sure you’re entering the correct 16–20 digit code.
  • Check Region Settings: Some DVRs are region-locked. Ensure your app and DVR are set to the same region (e.g., North America).
  • Reboot DVR: Power cycle the DVR to refresh the connection.

Slow or Laggy Video

  • Check Upload Speed: Use a speed test tool. Aim for at least 1 Mbps upload.
  • Reduce Resolution: In the DVR settings, lower the stream quality for remote viewing.
  • Close Other Apps: Background apps can slow down your phone.

App Crashes or Freezes

  • Update the App: Make sure you’re using the latest version of DMSS.
  • Clear Cache: Go to your phone’s settings and clear the app’s cache.
  • Reinstall DMSS: Uninstall and reinstall the app if problems persist.

Security Tips for P2P Users

While P2P is secure, it’s important to follow best practices:

  • Change Default Passwords: Never leave the admin password as “admin” or “123456.” Use a strong, unique password.
  • Enable Two-Factor Authentication (2FA): If your Dahua account supports it, turn on 2FA for extra protection.
  • Update Firmware Regularly: Dahua releases updates to fix bugs and security flaws.
  • Limit User Access: Only give login credentials to trusted people.
