Losing access to your Dahua DVR or NVR because of a forgotten admin password can be frustrating and stressful. Fortunately, recovering or resetting your Dahua DVR password is possible by following a few reliable methods. Whether you want to perform a Dahua DVR password reset through a hard reset or generate a temporary password using a date-based tool, this guide covers the essential steps to regain access without hassle.

Understanding Dahua Password Reset Challenges

Dahua DVRs and NVRs often come with security features that complicate password recovery. Some devices require a physical reset using a button on the motherboard, while others depend on software utilities or default passwords. In addition, different Dahua firmware versions—ranging from 3.1 to 7.x—may have unique requirements like enabling the “user account” function after rebooting, which affects default password acceptance.

Because Dahua has several OEM partners and compatible brands (such as Amcrest, Lorex, Honeywell, and more), the following reset techniques generally work across multiple models that share Dahua’s web interface and architecture.

Reset Using the Physical Reset Button

Some Dahua DVRs/NVRs include a reset button on their motherboard. To try this method:

Power off your DVR/NVR.

Locate and press the reset button (you might need to open the case).

While holding the reset button, power on the device.

Keep pressing the button for around 30 seconds until the startup wizard appears.

Follow the prompts to create a new admin password.

This method restores the device to factory defaults, so all previous settings and recordings might be erased. Always backup data if possible before resetting.

Use Default Passwords

If you have never changed the password or are unsure, try logging in with Dahua’s default credentials. Often, the username is “admin” or “root,” and the password might be blank or set to “9999@” (note that this password may not work after reboot on newer firmware versions). If successful, immediately update your password for security.

Generate a Daily Password

Dahua provides a daily password generator tool that uses the device’s date/time stamp to generate a temporary login password. This method requires:

• Access to the date/time displayed on your DVR/NVR screen.
• Inputting the date in YYYYMMDD format into the password generator.
• Using the generated password to login and reset the admin password.

This approach is useful if the default password or reset button methods don’t work.

Additional Tips: Battery Removal & Dealer Support

Another way to reset the device is by removing the CMOS battery on the motherboard, which resets the system clock and sometimes the password. This method requires opening your device carefully.

If all else fails, contacting the Dahua dealer or reseller where you purchased the device may be the easiest solution. Many dealers can remotely reset your password quickly through Dahua’s support channels.

Conclusion

Recovering your Dahua DVR password doesn’t have to be complicated. By following these proven methods—using a physical reset button, default passwords, or the daily password generator—you can regain control of your surveillance system efficiently. Always remember to secure your new password and back up your recordings regularly to avoid future lockouts.
