Whatever the reason, performing a factory hard reset can bring your device back to its original state, wiping all custom settings and restoring default configurations. But before you hit that reset button (literally or digitally), it’s important to understand what a factory hard reset does, the risks involved, and the best methods to get it done safely and effectively.
In this comprehensive guide, we’ll walk you through every reliable method to factory hard reset a Dahua DVR. Whether you have physical access to the device, can log in via the web interface, or need to use specialized software, we’ve got you covered. We’ll also share practical tips, troubleshooting advice, and post-reset setup steps to ensure your DVR runs smoothly afterward. By the end of this guide, you’ll know exactly how to reset your Dahua DVR with confidence—no technical jargon, no guesswork.
What Is a Factory Hard Reset?
A factory hard reset, also known as a factory restore or master reset, returns your Dahua DVR to its original出厂 settings—the way it was when it left the factory. This means all user accounts, passwords, recording schedules, network settings, motion detection rules, and stored video data will be erased. The firmware remains intact, but all custom configurations are wiped clean.

This process is useful in several scenarios:
- You’ve forgotten the admin password and can’t log in.
- The DVR is malfunctioning, freezing, or experiencing software errors.
- You’re transferring ownership of the device (e.g., selling or donating).
- You want to start fresh with a clean configuration.
It’s important to note that a factory reset is irreversible. Once initiated, there’s no “undo” button. That’s why backing up your configuration (if possible) is a critical first step.
Before You Begin: Important Precautions
Before performing a factory hard reset on your Dahua DVR, take these precautions to avoid data loss and ensure a smooth process:
1. Back Up Your Configuration
If you still have access to the DVR’s interface, export your current settings. This includes camera names, recording schedules, motion detection zones, and network settings. While a reset will erase these, having a backup lets you restore them quickly afterward.
- Go to Main Menu > System > Maintenance > Import/Export.
- Select Export Configuration and save the file to a USB drive or your computer.
2. Note Down Critical Settings
Write down important details such as:
- IP address and subnet mask
- Camera names and channels
- Recording schedule (continuous, motion, etc.)
- User accounts and permissions
- FTP or cloud storage settings (if used)
This will save you time when reconfiguring the DVR after the reset.
3. Ensure Stable Power Supply
A power interruption during the reset process can corrupt the system. Use a reliable power source and avoid unplugging the DVR until the reset is complete.
4. Disconnect Cameras (Optional but Recommended)
If you’re troubleshooting hardware issues, disconnect all cameras before resetting. This helps isolate whether the problem is with the DVR or a connected device.
5. Check Your Model and Firmware
Different Dahua DVR models may have slightly different reset procedures. Check your model number (usually on a label on the device) and ensure your firmware is up to date. You can find this in Main Menu > System > Information.
Method 1: Factory Reset Using the Physical Reset Button
The most reliable way to perform a factory hard reset—especially if you’ve forgotten the password—is using the physical reset button on the DVR. This method works on most Dahua DVR models, including the popular XVR5104HS, XVR5108HS, and older analog models.
Step 1: Locate the Reset Button
The reset button is typically a small, recessed button located on the back or side of the DVR. It’s often labeled “RESET” or marked with a circular arrow icon. You’ll need a paperclip, pin, or similar thin tool to press it.
Step 2: Power On the DVR
Ensure the DVR is powered on and fully booted. Wait until the system is operational (you should see the login screen or live view).
Step 3: Press and Hold the Reset Button
Using a paperclip, press and hold the reset button for 10 to 15 seconds. Do not release it too early. The exact duration may vary by model, but 10–15 seconds is standard.
Step 4: Wait for the Reset to Complete
After releasing the button, the DVR will automatically reboot. You’ll see the system restart, and the LED indicators may flash. This process can take 1–3 minutes. Do not power off the device during this time.
Step 5: Log In with Default Credentials
Once the DVR restarts, it will return to factory settings. The default username is usually admin, and the default password is either admin or 123456. Some newer models may require you to set a new password on first login.
Tip: If the reset doesn’t work, try holding the button for up to 20 seconds. Some models require a longer press.
Method 2: Factory Reset via Web Interface (If You Can Log In)
If you still remember your login credentials, you can perform a factory reset directly from the DVR’s web interface. This method is cleaner and allows you to back up settings first.
Step 1: Access the DVR’s Web Interface
Open a web browser on a computer connected to the same network as the DVR. Enter the DVR’s IP address (e.g., 192.168.1.108) in the address bar. Log in using your admin credentials.
Step 2: Navigate to System Maintenance
Once logged in, go to:
- Configuration > System > Maintenance
Alternatively, some models use:
- Main Menu > System > Maintenance
Step 3: Select Factory Reset
Look for an option labeled Factory Reset, Restore Defaults, or Initialize System. Click it.
Step 4: Confirm the Reset
A warning message will appear, stating that all settings and data will be erased. Confirm by clicking OK or Yes.
Step 5: Wait for Reboot
The DVR will automatically restart. This may take 2–5 minutes. Once it’s back online, log in using the default credentials (admin/admin or admin/123456).
Note: On some newer Dahua models, you may need to enter a verification code or answer a security question before the reset is allowed.
Method 3: Factory Reset Using Dahua Smart PSS Software
Dahua’s Smart PSS (Professional Surveillance System) is a free desktop application that lets you manage multiple Dahua devices, including performing remote resets. This method is ideal if you can’t access the DVR directly but have network access.
Step 1: Download and Install Smart PSS
Visit the official Dahua website and download Smart PSS for your operating system (Windows or macOS). Install and launch the software.
Step 2: Add Your DVR to Smart PSS
Click Device Manager and then Add Device. Enter the DVR’s IP address, port (usually 37777), username, and password. Click OK to add it.
Step 3: Access Device Maintenance
Right-click on the DVR in the device list and select Maintenance or System Maintenance.
Step 4: Perform Factory Reset
In the maintenance window, look for Factory Reset or Restore to Default. Click it and confirm when prompted.
Step 5: Monitor the Process
Smart PSS will send the reset command to the DVR. The device will reboot automatically. Wait a few minutes, then try logging in with default credentials.
Tip: Ensure your computer and DVR are on the same network. If you’re using a firewall, allow Smart PSS through it.
Method 4: Using Dahua ConfigTool (For Advanced Users)
ConfigTool is another Dahua utility designed for bulk configuration and troubleshooting. It can also perform factory resets, especially useful for IT professionals managing multiple devices.
Step 1: Download ConfigTool
Get ConfigTool from the Dahua support site. It’s a lightweight executable that doesn’t require installation.
Step 2: Scan for Devices
Launch ConfigTool and click Search to find all Dahua devices on your network. Select your DVR from the list.
Step 3: Log In
Enter the admin username and password. If you’ve forgotten them, you may need to use the physical reset method first.
Step 4: Initiate Reset
Click on the Maintenance tab and select Factory Reset. Confirm the action.
Step 5: Wait and Reconnect
The DVR will reset and reboot. Once done, reconnect using default login details.
Note: ConfigTool is best for technicians. If you’re not familiar with network tools, stick to the web interface or physical reset.
Troubleshooting Common Reset Issues
Even with careful steps, you might run into problems. Here’s how to handle the most common issues:
Issue 1: Reset Button Doesn’t Work
- Cause: The button may be damaged, or the DVR is in a protected mode.
- Solution: Try pressing the button for a full 20 seconds. If that fails, use the web interface or Smart PSS method. As a last resort, contact Dahua support.
Issue 2: DVR Doesn’t Reboot After Reset
- Cause: Power interruption or firmware corruption.
- Solution: Power cycle the DVR (unplug for 30 seconds, then reconnect). If it still won’t boot, you may need to reflash the firmware using Dahua’s firmware update tool.
Issue 3: Can’t Log In After Reset
- Cause: Default password may have changed, or the reset didn’t complete.
- Solution: Try common defaults: admin/admin, admin/123456, or admin/(blank). If none work, repeat the reset process. Some models require a password reset via USB or support ticket.
Issue 4: Cameras Not Detected After Reset
- Cause: Camera settings were reset, or connections are loose.
- Solution: Reconnect all cameras and check power. Reconfigure camera names and channels in the DVR menu.
Issue 5: Network Settings Lost
- Cause: IP address reverted to default (often 192.168.1.108).
- Solution: Reconfigure the IP address to match your network. Use DHCP or set a static IP as needed.
Post-Reset Setup: Getting Your DVR Back Online
After a successful factory hard reset, your Dahua DVR is essentially a brand-new device. Here’s how to get it up and running again:
1. Change the Default Password
Immediately after logging in, change the admin password to something strong and unique. Go to Main Menu > System > User Management and update the password.
2. Reconfigure Network Settings
Set a static IP address or enable DHCP, depending on your network. Ensure the DVR can communicate with your router and other devices.
3. Add Cameras
If using analog or TVI cameras, they should auto-detect. For IP cameras, manually add them via Camera Management.
4. Set Up Recording
Configure recording schedules—continuous, motion-triggered, or scheduled. Adjust motion detection zones if needed.
5. Enable Remote Access (Optional)
If you want to view the DVR remotely, set up DDNS, port forwarding, or use Dahua’s P2P service (via QR code in the mobile app).
6. Update Firmware
Check for firmware updates in System > Maintenance > Upgrade. Updating ensures security patches and performance improvements.
7. Restore Configuration (If Backed Up)
If you exported your settings earlier, go to Import/Export and restore the configuration file. This will save hours of reconfiguration.
When to Avoid a Factory Reset
While a factory reset is a powerful tool, it’s not always the best solution. Avoid resetting if:
- You’re unsure about the consequences and haven’t backed up data.
- The DVR is under warranty and the issue might be hardware-related.
- You’re in a critical surveillance environment (e.g., business security) and can’t afford downtime.
- You suspect a hardware failure (e.g., hard drive error, overheating).
In these cases, contact Dahua technical support or a certified technician before proceeding.
Final Thoughts
Performing a factory hard reset on your Dahua DVR is a straightforward process—if you follow the right steps. Whether you use the physical button, web interface, or software tools, the key is preparation: back up your data, note your settings, and ensure stable power. Once reset, take the time to reconfigure your DVR properly to avoid future issues.
Remember, a factory reset is a last-resort solution for persistent problems or access issues. Use it wisely, and always prioritize data safety. With this guide, you’re now equipped to reset your Dahua DVR confidently and get back to reliable surveillance in no time.
