But what if you want to check your cameras while you’re out shopping, traveling, or just relaxing in another room? That’s where mobile access comes in. Accessing your Dahua DVR on mobile lets you monitor live feeds, review recordings, and even control PTZ (pan-tilt-zoom) cameras right from your smartphone or tablet.

In this guide, we’ll walk you through everything you need to know to get your Dahua DVR connected to your mobile device. Whether you’re a tech beginner or a DIY enthusiast, we’ll keep it simple, clear, and practical. By the end, you’ll be able to view your security cameras anytime, anywhere—no matter where life takes you.

Why Access Dahua DVR on Mobile?

Let’s be honest—security isn’t just about installing cameras. It’s about being able to see what’s happening in real time, even when you’re not there. Accessing your Dahua DVR on mobile gives you peace of mind. Imagine getting a motion alert while you’re at work and instantly pulling up the live feed to see if it’s a delivery person or something suspicious. Or checking in on your pets while you’re on vacation.

Mobile access also adds convenience. You don’t need to sit in front of a monitor or be tied to a specific location. With the right setup, your phone becomes a portable surveillance center. Plus, modern Dahua systems are designed with mobile users in mind, offering smooth streaming, intuitive apps, and secure connections.

What You’ll Need Before You Start

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

• A Dahua DVR or NVR system – This guide focuses on DVRs, but many steps also apply to NVRs.
• A smartphone or tablet – iOS (iPhone/iPad) or Android device.
• Internet connection – Both your DVR and mobile device should have internet access (Wi-Fi or mobile data).
• Dahua mobile app installed – We’ll cover this next.
• DVR login credentials – Default is usually admin/admin or admin/123456, but change this for security.
• DVR’s IP address or serial number – Needed for connection, especially for remote access.

Having these ready will make the process much smoother. If you’re unsure about your DVR’s IP address or login details, check the user manual or look for a label on the device.

Step 1: Download the Official Dahua Mobile App

The first step to accessing your Dahua DVR on mobile is installing the right app. Dahua offers two main mobile apps:

• DMSS (Digital Mobile Surveillance System) – The newer, more user-friendly app with better performance and features.
• SmartPSS Mobile – The older app, still functional but gradually being phased out in favor of DMSS.

We recommend using DMSS for the best experience. It supports more DVR models, has a cleaner interface, and receives regular updates.

How to Download DMSS

1. Open the App Store (iOS) or Google Play Store (Android) on your mobile device.
2. Search for “DMSS” or “Dahua DMSS”.
3. Download and install the app from the official Dahua Technology developer.
4. Once installed, open the app.

Tip: Avoid third-party apps or unofficial versions. They may not work properly or could compromise your security.

Step 2: Connect Your DVR to the Internet

To access your DVR remotely, it must be connected to the internet. Most Dahua DVRs have an Ethernet port for this purpose.

Wired Connection (Recommended)

1. Use an Ethernet cable to connect your DVR to your router or modem.
2. Power on the DVR and wait a few minutes for it to boot up.
3. Check the network status on the DVR’s local interface (usually under Network > TCP/IP).
4. Ensure the DVR has obtained an IP address (e.g., 192.168.1.108).

Note: If your DVR doesn’t get an IP address, check your router settings or restart the device.

Wireless Connection (If Supported)

Some newer Dahua DVRs support Wi-Fi. If yours does:

1. Go to Network > Wi-Fi in the DVR menu.
2. Select your Wi-Fi network and enter the password.
3. Save and restart the DVR if needed.

Warning: Not all Dahua DVRs support Wi-Fi. Check your model’s specifications first.

Step 3: Set Up P2P (Plug-and-Play) for Easy Mobile Access

The easiest way to access your Dahua DVR on mobile is through P2P (Peer-to-Peer) technology. P2P allows you to connect without dealing with IP addresses, port forwarding, or DDNS. Most modern Dahua DVRs support P2P out of the box.

Enable P2P on Your DVR

1. On the DVR, go to Main Menu > Network > P2P.
2. Make sure P2P is enabled (toggle to “On”).
3. Note the Serial Number or QR Code displayed on the screen. This is your device’s unique ID.

Tip: Write down the serial number or take a screenshot of the QR code for easy reference.

Add Your DVR to the DMSS App Using P2P

1. Open the DMSS app on your phone.
2. Tap the + or Add Device button.
3. Select Scan QR Code and point your camera at the QR code on the DVR screen.
4. Alternatively, choose Manual Input and enter the serial number.
5. Enter your DVR’s login credentials (username and password).
6. Tap Add or Connect.

Within seconds, your DVR should appear in the app. You can now view live feeds, playback recordings, and adjust settings.

Pro Tip: If the QR code doesn’t scan, ensure good lighting and clean the DVR screen. You can also manually enter the serial number.

Step 4: Alternative Connection Methods (If P2P Fails)

Sometimes P2P doesn’t work due to network restrictions or older DVR models. In those cases, you can use other methods to access your Dahua DVR on mobile.

Method 1: Local Network (Same Wi-Fi)

If your phone and DVR are on the same network (e.g., both connected to your home Wi-Fi), you can connect directly.

1. Find your DVR’s local IP address (usually under Network > TCP/IP).
2. Open the DMSS app.
3. Tap Add Device > IP/Domain.
4. Enter the IP address (e.g., 192.168.1.108).
5. Set the port to 37777 (default for Dahua).
6. Enter your username and password.
7. Tap Add.

This method only works when you’re at home or on the same network. For remote access, use P2P or DDNS.

Method 2: DDNS (Dynamic DNS)

DDNS lets you access your DVR using a custom web address (like mydvr.dahuaddns.com) instead of a changing IP address.

1. On the DVR, go to Network > DDNS.
2. Select a DDNS provider (Dahua offers a free one: www.dahuaddns.com).
3. Register an account on the DDNS website and create a hostname (e.g., myhome-dvr).
4. Enter the DDNS settings on the DVR (server, username, password, hostname).
5. Save and test the connection.
6. In the DMSS app, add the device using the DDNS hostname and port 37777.

Note: DDNS requires a static public IP or a router that supports dynamic DNS updates.

Method 3: Port Forwarding (Advanced)

Port forwarding opens a specific port on your router to allow external access to your DVR. This method is more technical and less secure if not configured properly.

1. Log in to your router’s admin panel (usually via 192.168.1.1).
2. Find the Port Forwarding or Virtual Server section.
3. Add a new rule:
   • Service Name: Dahua DVR
   • External Port: 37777
   • Internal IP: Your DVR’s local IP (e.g., 192.168.1.108)
   • Internal Port: 37777
   • Protocol: TCP/UDP
4. Save the settings.
5. In the DMSS app, add the device using your public IP address and port 37777.

Warning: Port forwarding exposes your DVR to the internet. Use strong passwords and consider disabling it when not in use.

Step 5: Configure Mobile App Settings

Once your DVR is connected, customize the app for the best experience.

Adjust Video Quality

To save data and improve streaming on mobile networks:

1. Open the camera feed in DMSS.
2. Tap the Settings (gear) icon.
3. Go to Video Quality and select Low or Medium for mobile data.
4. Use High only on Wi-Fi for better clarity.

Enable Push Notifications

Get alerts when motion is detected:

1. In DMSS, go to Device Settings > Alarm Settings.
2. Enable Motion Detection and Push Notification.
3. Set sensitivity and detection zones if needed.

Set Up User Permissions

If multiple people use the system, create separate accounts with limited access:

1. On the DVR, go to Main Menu > User Management.
2. Add a new user with a unique username and password.
3. Assign permissions (e.g., view only, no playback).
4. Use this account in the mobile app for shared access.

Step 6: Troubleshooting Common Issues

Even with the best setup, you might run into problems. Here’s how to fix the most common ones when trying to access your Dahua DVR on mobile.
