How to Reset Dahua Dvr

Resetting your Dahua DVR can solve many common issues like forgotten passwords or system glitches. This guide walks you through every method—soft reset, hard reset, and password recovery—so you can restore your system quickly and safely.

Key Takeaways

• Understand the difference between soft and hard resets: A soft reset restarts the system without losing settings, while a hard reset restores factory defaults and erases all data.
• Always back up your configuration before resetting: Use the DVR’s export feature to save camera layouts, recording schedules, and network settings.
• Use the correct reset method for your model: Some Dahua DVRs have a physical reset button, while others require software-based password recovery tools.
• Prepare necessary tools in advance: You may need a paperclip, USB drive, computer, or the Dahua Config Tool software depending on the reset method.
• Reset only when necessary: Frequent resets can wear out hardware and disrupt surveillance operations—use as a last resort after troubleshooting.
• Reconfigure settings post-reset: After a hard reset, you’ll need to set up time, date, network, cameras, and recording schedules again.
• Contact Dahua support if standard methods fail: For advanced models or firmware issues, official support may provide unique recovery keys or firmware fixes.

Resetting your Dahua DVR can restore functionality, clear configuration errors, and get your security system back on track. But before you press that reset button, it’s important to understand the different types of resets, what they do, and how to do them safely.

In this comprehensive guide, you’ll learn how to reset your Dahua DVR using multiple methods, including soft resets, hard resets, and password recovery tools. We’ll cover everything from backing up your settings to reconfiguring your system after a reset. Whether you’re a homeowner managing a small setup or a security professional handling multiple units, this guide will walk you through the process clearly and simply.

By the end of this article, you’ll know exactly when and how to reset your Dahua DVR—without losing important data or causing further issues. Let’s get started.

Why Reset Your Dahua DVR?

Before diving into the how-to, let’s talk about why you might need to reset your Dahua DVR in the first place. Understanding the reasons will help you choose the right reset method and avoid unnecessary steps.

Common reasons to reset a Dahua DVR include:

• Forgotten admin password: This is the most frequent reason. If you can’t log in, a reset may be the only way to regain access.
• System freezes or crashes: If the DVR becomes unresponsive or reboots randomly, a reset can clear temporary glitches.
• Configuration errors: Incorrect network settings, camera mismatches, or recording schedule conflicts can sometimes only be fixed by starting fresh.
• Preparing for resale or reuse: If you’re transferring ownership or repurposing the DVR, a factory reset ensures no personal data remains.
• Firmware update issues: Failed updates can leave the system in an unstable state, requiring a reset to recover.

It’s important to note that not all problems require a full reset. Try basic troubleshooting first—like restarting the device, checking cables, or rebooting your network. But if those don’t work, a reset is often the next logical step.

Types of Dahua DVR Resets

Not all resets are created equal. Dahua DVRs support different types of resets, each with its own purpose and outcome. Knowing the difference will help you choose the right one for your situation.

Soft Reset (Restart)

A soft reset is simply restarting the DVR. It’s the safest option and doesn’t erase any data or settings. This is useful if the system is slow, frozen, or experiencing minor software hiccups.

To perform a soft reset:

• Go to the DVR’s main menu.
• Navigate to Maintenance > Shutdown.
• Select Reboot and confirm.

The DVR will shut down and restart automatically. This usually takes 1–2 minutes. After rebooting, check if the issue is resolved.

Hard Reset (Factory Reset)

A hard reset restores the DVR to its original factory settings. This means all configurations—including camera settings, recording schedules, network settings, and user accounts—will be erased. Only perform this if you’re prepared to reconfigure everything.

Use a hard reset when:

• You’ve forgotten the admin password and can’t recover it.
• The system is severely malfunctioning.
• You’re preparing the device for a new user.

There are two main ways to perform a hard reset: using the physical reset button or through software tools.

Password Recovery Reset

If you’ve forgotten your password but don’t want to lose all settings, Dahua offers a password recovery method. This involves generating a reset code using the DVR’s serial number and a timestamp, which you send to Dahua support or use with their Config Tool.

This method is ideal when you want to regain access without wiping the entire system.

How to Perform a Soft Reset on Dahua DVR

Let’s start with the simplest method: the soft reset. This is the first thing you should try if your DVR is acting up.

Step 1: Access the Main Menu

Power on your DVR and connect a monitor. Use the mouse or remote control to navigate to the main menu. Look for the gear or settings icon.

Step 2: Go to Maintenance

In the main menu, find and click on Maintenance. This section contains system tools like reboot, shutdown, and firmware updates.

Step 3: Select Reboot

Under Maintenance, choose Shutdown. You’ll see options like Shutdown, Reboot, and Logout. Click Reboot.

Step 4: Confirm the Action

A confirmation window will appear. Click OK or Yes to proceed. The DVR will begin shutting down and restart automatically.

Step 5: Wait for Restart

The reboot process typically takes 1–2 minutes. Once complete, the DVR will return to the live view screen. Log in with your credentials and check if the issue is resolved.

Tip: If the DVR doesn’t respond to the menu, try unplugging it from power for 30 seconds, then plug it back in. This is a manual soft reset and often works when the interface is frozen.

How to Perform a Hard Reset Using the Physical Button

If a soft reset doesn’t work, and you need to restore factory settings, the physical reset button is your best bet. Most Dahua DVRs have a small reset button located on the back or side of the unit.

Step 1: Locate the Reset Button

Turn off the DVR and unplug it from power. Look for a small hole labeled “Reset” or “RST” on the back panel. It’s usually next to the power input or network ports.

Step 2: Prepare a Paperclip

You’ll need a thin, straight object like a paperclip or pin to press the button inside the hole.

Step 3: Press and Hold the Reset Button

While the DVR is powered off, insert the paperclip into the reset hole and press the button inside. Hold it down for 10–15 seconds.

Step 4: Power On While Holding

While still holding the reset button, plug the DVR back into power. Continue holding the button for another 10–15 seconds after power is restored.

Step 5: Release and Wait

Release the button. The DVR will boot up normally. You’ll notice that all settings have been erased—no cameras, no users, no recordings.

Important: This method works on most Dahua DVR models, but not all. Check your user manual to confirm if your model supports hardware reset. Some newer models may require software-based reset instead.

How to Reset Dahua DVR Using Dahua Config Tool

If your DVR doesn’t have a physical reset button, or if you prefer a software-based approach, the Dahua Config Tool is a powerful utility for managing and resetting devices.

Step 1: Download and Install Dahua Config Tool

Visit the official Dahua website and download the Dahua Config Tool. Install it on a Windows computer connected to the same network as your DVR.

Step 2: Connect the DVR to the Network

Ensure your DVR is connected to your router via Ethernet. The Config Tool communicates over the network, so a stable connection is essential.

Step 3: Launch the Config Tool

Open the software. It will automatically scan the network for Dahua devices. Your DVR should appear in the device list with its IP address, model, and status.

Step 4: Log In to the DVR

Double-click your DVR in the list. Enter the current admin username and password. If you’ve forgotten the password, skip to the password recovery section below.

Step 5: Navigate to Maintenance

Once logged in, go to the Maintenance tab. Look for options like Restore, Factory Reset, or Default Settings.

Step 6: Perform Factory Reset

Click Factory Reset or Restore to Default. Confirm the action when prompted. The tool will send the reset command to the DVR.

Step 7: Wait for Completion

The DVR will reboot automatically. This may take a few minutes. Once done, all settings will be erased, and the DVR will return to factory defaults.

Tip: The Config Tool also allows you to back up and restore configurations. Always back up your settings before performing a reset.

How to Recover a Forgotten Password on Dahua DVR

Forgetting your admin password is frustrating, but Dahua provides a secure way to recover it without losing all your settings.

Step 1: Access the Login Screen

When you try to log in and enter the wrong password, the system will display an error. Look for a Forgot Password? or Reset Password option.

Step 2: Generate a Reset Code

Click the reset option. The DVR will display a Serial Number and a Timestamp. Write these down or take a screenshot.

Step 3: Use Dahua Config Tool or Contact Support

Open the Dahua Config Tool on your computer. Go to the Password Recovery section. Enter the serial number and timestamp from your DVR.

The tool will generate a Reset Code. Enter this code into the DVR’s password reset screen.

Step 4: Set a New Password

Once the code is accepted, you’ll be prompted to create a new admin password. Choose a strong, memorable password and confirm it.

Step 5: Log In with New Credentials

Use your new password to log in. All previous settings will remain intact—only the password has changed.

Note: If the Config Tool doesn’t work, contact Dahua technical support with the serial number and timestamp. They can provide a reset code manually.

How to Back Up Settings Before Resetting

Before performing any reset—especially a hard reset—it’s crucial to back up your configuration. This saves time when reconfiguring the system afterward.

Step 1: Log In to the DVR

Access the DVR’s web interface or local menu using a monitor and mouse.

Step 2: Go to Maintenance > Backup

Navigate to Maintenance > Backup & Restore or Configuration.

Step 3: Export Configuration

Click Export or Backup. Save the file to a USB drive or your computer. The file will have a .cfg or .dav extension.

Step 4: Store the Backup Safely

Keep the backup file in a secure location. You’ll need it to restore settings after the reset.

Tip: Back up regularly—especially after making major changes like adding cameras or adjusting recording schedules.

Troubleshooting Common Reset Issues

Even with careful steps, reset issues can occur. Here’s how to handle the most common problems.

DVR Doesn’t Respond After Reset

If the DVR doesn’t boot up or shows a black screen:

• Check power connections and cables.
• Try a different monitor or HDMI cable.
• Ensure the hard drive is properly seated (if applicable).
• Contact Dahua support—the reset may have corrupted the firmware.

Reset Button Doesn’t Work

If pressing the physical reset button has no effect:

• Confirm you’re holding it long enough (10–15 seconds).
• Ensure the DVR is powered off before starting.
• Try the software reset method instead.
• Check if your model supports hardware reset—some don’t.

Can’t Access Config Tool

If the Config Tool doesn’t detect your DVR:

• Verify both devices are on the same network.
• Disable firewalls or antivirus software temporarily.
• Ensure the DVR’s IP address is reachable (try pinging it).
• Update the Config Tool to the latest version.

Password Recovery Fails

If the reset code doesn’t work:

• Double-check the serial number and timestamp.
• Ensure the timestamp is within the valid window (usually 24 hours).
• Try generating a new code with an updated timestamp.
• Contact Dahua support for assistance.

Reconfiguring Your DVR After a Reset

After a hard reset, your DVR will be blank. You’ll need to set it up from scratch.

Step 1: Set Date and Time

Go to System > General > Date & Time. Enable NTP or manually set the correct time zone and current time.

Step 2: Configure Network Settings

Navigate to Network > TCP/IP. Set a static IP or use DHCP. Ensure the gateway and DNS are correct.

Step 3: Add Cameras

Go to Camera > Channel Management. The DVR should auto-detect connected cameras. Assign names and adjust settings like resolution and frame rate.

Step 4: Set Up Recording

Go to Storage > Schedule. Configure recording modes (continuous, motion, alarm) and set schedules.

Step 5: Create User Accounts

Under User Management, add new users with appropriate permissions. Set strong passwords.

Step 6: Restore from Backup (Optional)

If you backed up your settings, go to Maintenance > Backup & Restore and import the .cfg file. This will restore most configurations automatically.

Best Practices for Dahua DVR Maintenance

To avoid frequent resets, follow these maintenance tips:

• Update firmware regularly: Check Dahua’s website for updates that fix bugs and improve stability.
• Monitor hard drive health: Use the DVR’s SMART tool to check for disk errors.
• Keep the system cool: Ensure proper ventilation to prevent overheating.
• Use strong passwords: Avoid default credentials like “admin” and “12345”.
• Schedule regular backups: Save configurations weekly or after major changes.
