How to Factory Reset Dahua Dvr

Resetting your Dahua DVR to factory settings can resolve performance issues, forgotten passwords, or configuration errors. This guide walks you through multiple reset methods—including front panel, web interface, and hardware options—ensuring a smooth, secure process.

Key Takeaways

• Factory reset restores default settings: It erases all custom configurations, including user accounts, recording schedules, and network settings, returning the DVR to its original state.
• Multiple reset methods available: You can reset via the front panel button, web interface, mobile app, or by using a physical jumper on the motherboard (for advanced users).
• Backup important data first: Always save recordings, configurations, and user settings before resetting to avoid permanent data loss.
• Use the correct reset type: Dahua DVRs support both soft reset (preserves some settings) and full factory reset (erases everything)—choose wisely based on your needs.
• Reconfigure after reset: After resetting, you’ll need to set up the system again, including time, date, network, and recording preferences.
• Password recovery may require reset: If you’ve forgotten your admin password, a factory reset is often the only solution unless you have access to Dahua’s password recovery tool.
• Check firmware compatibility: Ensure your DVR’s firmware supports the reset method you plan to use—older models may have limitations.

Why Factory Reset a Dahua DVR?

Before diving into the how-to, it’s important to understand why you might need to perform a factory reset. While it’s not something you should do lightly—since it erases all custom settings—there are several valid reasons:

• Forgotten admin password: If you’ve lost access to your DVR and can’t log in, a factory reset is often the only way to regain control.
• System performance issues: Over time, DVRs can slow down due to corrupted settings or software glitches. A reset can restore smooth operation.
• Preparing for resale or transfer: If you’re selling or giving away your DVR, a factory reset ensures no personal data or configurations remain.
• Configuration errors: Incorrect network settings, recording schedules, or camera assignments can cause malfunctions. Resetting clears these errors.
• Malware or unauthorized access: In rare cases, a DVR may be compromised. A factory reset removes any unauthorized changes.

Always remember: a factory reset is a last-resort solution. Try troubleshooting first—restarting the device, checking cables, or updating firmware—before wiping everything.

Before You Reset: Important Precautions

Resetting your Dahua DVR will erase all data, including:

• User accounts and passwords
• Recording schedules and motion detection settings
• Network configurations (IP address, port settings, etc.)
• Camera names and channel assignments
• System time and date
• Custom video quality and compression settings

Because of this, it’s crucial to take the following steps before proceeding:

1. Backup Your Recordings

If you have important footage stored on the DVR’s hard drive, back it up immediately. Use a USB drive or external hard drive to export recordings via the DVR’s playback menu.

• Insert a formatted USB drive into the DVR’s USB port.
• Go to Playback > Export and select the time range and channels.
• Choose the USB drive as the destination and start the export.
• Wait for the process to complete—do not remove the USB drive prematurely.

Tip: Label your backup clearly with the date and content description for easy retrieval later.

2. Save Configuration Files (If Possible)

Some Dahua DVR models allow you to export configuration files that store settings like network info, user permissions, and recording rules.

• Log in to the DVR’s web interface (usually via a browser using the DVR’s IP address).
• Navigate to System > Maintenance > Import/Export.
• Click Export Configuration and save the file to your computer.

This file can be imported after the reset to restore most settings—except passwords, which are always cleared.

3. Note Down Critical Settings

Write down or take screenshots of:

• IP address and subnet mask
• Admin username and password (if known)
• Recording schedule
• Camera names and positions
• Motion detection zones

This will make reconfiguration much faster after the reset.

4. Ensure Stable Power and Internet

A factory reset can take several minutes. Interruptions during the process may corrupt the system. Make sure:

• The DVR is plugged into a reliable power source.
• If using remote access, your internet connection is stable.
• No one else is accessing the DVR during the reset.

Method 1: Factory Reset via Front Panel Button

The simplest and most common way to reset a Dahua DVR is using the physical reset button on the front or back panel. This method works on most models, including the NVR series and standalone DVRs.

Step-by-Step Instructions

1. Locate the Reset Button: Look for a small, recessed button labeled “Reset” or “RST.” It’s usually on the front or rear panel, near the power button or USB ports. You’ll need a paperclip or pin to press it.
2. Power On the DVR: Ensure the DVR is turned on and fully booted. The status lights should be steady.
3. Press and Hold the Reset Button: Insert the paperclip and press the button firmly. Hold it for 10 to 15 seconds. You may see the status lights blink or the screen go blank.
4. Wait for Reboot: Release the button and wait. The DVR will restart automatically. This may take 2–5 minutes.
5. Confirm Reset: Once the system boots up, log in using the default credentials (usually admin with no password or admin/123456). If you can access the system, the reset was successful.

Tip: If the reset doesn’t work, try holding the button longer (up to 20 seconds) or repeat the process.

When to Use This Method

This is ideal when:

• You can’t access the web interface.
• The DVR is unresponsive to remote commands.
• You’re near the physical device and prefer a quick fix.

Limitations

• Does not work on all models—some require a combination of buttons.
• May not fully erase all settings on newer firmware versions.
• Always verify the reset by checking if default settings are restored.

Method 2: Factory Reset via Web Interface

If you can still access the DVR’s web interface, this method gives you more control and confirmation options. It’s especially useful for remote management.

Step-by-Step Instructions

1. Access the Web Interface: Open a web browser and enter the DVR’s IP address (e.g., 192.168.1.108). Log in with your admin credentials.
2. Navigate to Maintenance: Go to System > Maintenance > Default or Factory Reset.
3. Select Reset Type: Choose between:
   • Restore Default Settings: Resets most settings but may preserve network and user info.
   • Factory Reset: Erases everything, including network settings and user accounts.
4. Confirm the Reset: Click OK or Apply. A warning message will appear—confirm again.
5. Wait for Reboot: The DVR will restart automatically. Do not disconnect power.
6. Reconfigure the System: After reboot, log in with default credentials and set up the DVR again.

Tip: Use a wired connection (Ethernet) for stability during the reset process.

Advantages of Web Interface Reset

• More precise control over what gets reset.
• Can be done remotely if network access is available.
• Provides confirmation dialogs to prevent accidental resets.

Troubleshooting Web Interface Issues

If you can’t access the web interface:

• Check the IP address using Dahua’s ConfigTool software.
• Ensure your computer is on the same network.
• Try accessing via the Dahua mobile app (DMSS).
• Reset the network settings first, then retry.

Method 3: Factory Reset via Mobile App (DMSS)

The Dahua Mobile Surveillance System (DMSS) app allows you to manage your DVR remotely. You can perform a factory reset directly from your smartphone or tablet.

Step-by-Step Instructions

1. Open the DMSS App: Launch the app on your iOS or Android device.
2. Add or Select Your DVR: If not already added, scan the QR code on the DVR or enter the device info manually.
3. Access Device Settings: Tap the device name, then go to Settings (gear icon).
4. Navigate to Maintenance: Look for System > Maintenance > Factory Reset.
5. Confirm the Reset: Tap OK when prompted. The app will send the command to the DVR.
6. Wait for Reboot: The DVR will restart. You may lose connection temporarily.
7. Reconnect and Reconfigure: Once back online, log in with default credentials and set up the system.

Tip: Ensure your phone has a stable internet connection (Wi-Fi or cellular) during the process.

When to Use the Mobile App

This method is perfect when:

• You’re away from the DVR but have remote access.
• The front panel is inaccessible (e.g., DVR is in a locked cabinet).
• You prefer managing devices from your phone.

Limitations

• Requires prior setup and network configuration.
• May not work if the DVR is offline or has network issues.
• Some older models may not support remote reset via app.

Method 4: Hardware Reset Using Jumper (Advanced)

For situations where the DVR is completely unresponsive—no display, no network, no button response—a hardware reset using a jumper on the motherboard may be necessary. This method is recommended only for experienced users or technicians.

Step-by-Step Instructions

1. Power Off and Unplug the DVR: Turn off the device and disconnect all cables, including power.
2. Open the DVR Case: Use a screwdriver to remove the side or top panel. Be careful not to damage internal components.
3. Locate the Reset Jumper: Find a 2- or 3-pin header labeled “RESET,” “CLR_CMOS,” or similar. It’s usually near the CPU or BIOS chip.
4. Short the Jumper Pins: Use a small screwdriver or jumper cap to connect the two pins for 10–15 seconds. This clears the BIOS settings.
5. Reassemble and Power On: Replace the case, reconnect power, and turn on the DVR.
6. Verify Reset: Log in with default credentials. If successful, the reset worked.

Warning: Opening the DVR voids the warranty and risks damage. Proceed with caution.

When to Use This Method

Only use this if:

• All other reset methods have failed.
• The DVR is bricked or stuck in a boot loop.
• You have technical expertise and proper tools.

Safety Tips

• Work on a non-conductive surface.
• Ground yourself to avoid static discharge.
• Take photos before disassembling to aid reassembly.

Reconfiguring Your Dahua DVR After Reset

Step 1: Set Date and Time

Accurate time is crucial for recording logs and playback.

• Go to System > General > Date & Time.
• Enable NTP Sync to automatically sync with internet time servers.
• Or manually set the date, time, and time zone.

Step 2: Configure Network Settings

Restore your IP address, subnet mask, gateway, and DNS.

• Navigate to Network > TCP/IP.
• Choose Static IP or DHCP based on your network.
• Enter the correct IP details to ensure connectivity.

Step 3: Add Cameras and Name Channels

Reconnect your cameras and assign names for easy identification.

• Go to Camera > Channel Title.
• Enter descriptive names (e.g., “Front Door,” “Backyard”).
• Ensure all cameras are detected and displaying video.

Step 4: Set Up Recording Schedule

Define when and how the DVR should record.

• Go to Storage > Schedule.
• Select channels and set recording modes (continuous, motion, alarm).

Step 5: Create User Accounts

Add new users with appropriate permissions.

• Go to System > User.
• Add users and assign roles (admin, operator, guest).
• Set strong passwords for security.

Step 6: Enable Remote Access (Optional)

If you want to view your DVR remotely:

• Set up DDNS or P2P in Network > DDNS or P2P.
• Scan the QR code in the DMSS app to add the device.

Troubleshooting Common Reset Issues

Even with careful steps, problems can occur. Here’s how to fix the most common ones.

Issue 1: DVR Doesn’t Reboot After Reset

• Solution: Wait longer—some models take up to 10 minutes. If still unresponsive, try a power cycle (unplug for 30 seconds, then reconnect).

Issue 2: Can’t Log In After Reset

• Solution: Use default credentials: admin with no password, or admin/123456. If that fails, check the user manual for your specific model.

Issue 3: Cameras Not Detected

• Solution: Check camera power and cables. Re-add cameras manually in the channel settings.

Issue 4: Network Connection Lost

• Solution: Reconfigure IP settings. Use Dahua ConfigTool to find the DVR’s new IP address.

Issue 5: Reset Button Not Working

• Solution: Ensure you’re pressing the correct button and holding it long enough. Try the web interface or mobile app method instead.

Final Tips for a Smooth Reset Experience

• Always backup first: Never skip the backup step—data loss is permanent.
• Use the right method: Choose the reset method that matches your access level and technical skill.
• Keep firmware updated: After reset, check for firmware updates to improve stability and security.
