If you’re having trouble with your Dahua NVR or need to reset it, this guide will show you how. Please read this article carefully.

Dahua NVR Reset Methods:

There are two primary methods for resetting your Dahua NVR: using the physical reset button and through the software interface. Both methods achieve the same goal – restoring your NVR to its factory default settings – but differ in how they’re executed. Let’s explore each method in detail:

Method 1: Physical Reset Button

This method is ideal if you’ve forgotten your login credentials or your NVR is experiencing software issues. However, it’s important to remember that performing a physical reset completely erases all user configurations and settings, including usernames, passwords, network settings, and recording schedules.

Here’s how to perform a physical reset on your Dahua NVR:

Locate the Reset Button: The physical reset button is typically a small red button located on the back or underside of your NVR. Consult your Dahua NVR user manual for the exact location if unsure.

Power Off the NVR: Completely power down your NVR by disconnecting the power cable.
Hold the Reset Button: While the NVR is powered off, press and hold the reset button.
Power On While Holding: Keep holding the reset button while you reconnect the power cable and turn on the NVR.

Hold for 30 Seconds: Continue holding the reset button for approximately 30 seconds. You might see the NVR boot screen during this time.
Release and Reboot: After 30 seconds, release the reset button. The NVR will automatically reboot and initiate the factory reset process.

Method 2: Software Interface Reset

This method allows you to reset your Dahua NVR through the web interface, which is useful if you can still access the system but want to restore it to default settings. However, backing up important configurations beforehand is recommended (if possible) as the reset will erase all user data.

Here’s how to perform a software interface reset on your Dahua NVR:

Access the Web Interface: Launch a web browser on your computer and enter the IP address of your Dahua NVR in the address bar. This should open the NVR’s login page.
Login: Enter your username and password credentials to log in to the NVR interface.

Navigate to System Settings: Once logged in, locate the “System” or “Settings” menu within the NVR interface. The specific navigation path might vary slightly depending on your NVR model.
Find the Default Option: Within the System/Settings menu, look for an option labeled “Default” or “Factory Reset.”
Confirm Reset: Click on the “Factory Reset” or “Default” option. A confirmation window will likely appear, prompting you to confirm the reset process.

Confirm and Wait: Click “OK” or the confirmation button to initiate the factory reset. The NVR will take some time to erase data and reboot itself.

Important Note: After a successful reset using either method, you’ll need to configure your NVR again from scratch, including setting up new login credentials, network settings, and recording schedules.

There are a few risks associated with Dahua NVR Factory Reset:

You may lose any data stored on the device. This includes any pictures, videos, or documents you may have stored on the NVR.
If your NVR was connected to the internet at the reset, it might not be easy to connect again.

If security features were enabled on the device, they might be disabled after a factory reset.

If you’re concerned about any of these risks, it’s important to back up your data before performing a Factory reset.

Important Considerations During Reset:

Before proceeding with a Dahua NVR reset, it’s crucial to understand the implications and take necessary precautions:

1. Data Loss:

The most critical point to remember is that a factory reset completely wipes all user data and settings on your Dahua NVR. This includes:

Usernames and passwords

Network configurations (IP address, subnet mask, gateway)
Recording schedules and parameters
System configurations (date & time, language)

If you have critical recordings or configurations you want to retain, a factory reset is not the solution. Explore backup options available in your Dahua NVR user manual or consult Dahua support for alternative methods.

2. Password Recovery:

If your goal is simply to regain access to your NVR due to a forgotten password, a factory reset might be overkill. Consider exploring password recovery options first. Many Dahua NVR models offer built-in password recovery mechanisms. Consult your user manual or contact Dahua support to learn the specific steps for password recovery on your NVR model.

3. Camera Compatibility:

A factory reset can potentially disrupt camera connections to your NVR, especially if your cameras have separate passwords set. This is because the reset wipes out any saved camera credentials on the NVR. To ensure smooth camera operation after a reset, it’s recommended to reset the passwords on your cameras as well. Refer to your camera’s user manual for instructions on password reset specific to your camera model.

Reconfiguring Dahua NVR After Reset

After performing a factory reset, the NVR will require reconfiguration.

Initial Setup After a Reset

Re-enter Network Settings: Configure your network settings (IP address, DNS, etc.).
Add Cameras: Re-add and configure the cameras to connect with the NVR.
Set Up Password: Create a new admin password and set up security questions for future password recovery.

Configure Motion Detection/Recording: Customize your recording schedules, motion detection, and other settings.

Troubleshooting Common Reset Issues:

Even after following the proper reset procedures, you might encounter occasional issues. Here’s how to troubleshoot common problems that can arise during a Dahua NVR reset:

1. NVR Not Responding to Reset:

If your Dahua NVR doesn’t seem to respond to a physical reset attempt (pressing the button during power on doesn’t initiate the reset process), there could be a couple of reasons:

Faulty Reset Button: In rare cases, the physical reset button itself might be malfunctioning. Try a very gentle press to see if there’s any response. If not, consult your Dahua user manual for alternative reset methods specific to your NVR model.
Hardware Malfunction: A more serious possibility is a hardware malfunction within the NVR that’s preventing the reset process. In such cases, contacting Dahua support for repair or replacement is recommended.

2. Failed Login After Reset:

After successfully performing a Dahua NVR reset (either physical or software), you might find yourself unable to log in using your previous credentials. This is completely normal behavior. Remember, a factory reset wipes out all user data, including usernames and passwords.

Don’t panic! The reset process worked as intended. You’ll simply need to configure the NVR again from scratch, including setting up new login credentials, network settings, and recording schedules. Refer to your Dahua NVR user manual or online resources for detailed instructions on configuring your NVR after a reset.
