For most current Dahua DVR models, there is no single default password because the system enforces mandatory password creation during the initial setup. However, if you are working with an older or legacy unit, you can try several common factory-set combinations. Common Default Credentials
If your device has not been initialized or is a legacy model, try these username and password pairs:
Username: admin / Password: admin (Most common for cameras and older recorders)
Username: 888888 / Password: 888888 (Common administrator account for older local access)
Username: 666666 / Password: 666666 (Restricted user for monitor and playback only)
Username: admin / Password: 123456 (Found in some legacy firmware versions)
Default Pattern: On many newer touchscreen or mouse-controlled interfaces, the default unlock pattern is a capital "L" shape. Recovery Options if Defaults Fail dahua dvr default password
If the above credentials do not work, it means a custom password was set. You can use these methods to regain access:
The default password for a Dahua DVR depends heavily on the manufacturing date and firmware version. Newer models typically do not have a pre-set default; instead, they require you to create a strong password during the initial setup. Common Default Credentials
If your unit is an older model or has been recently factory reset, try these common combinations: Standard Admin: Username: admin | Password: admin. Legacy/Specific Models: Username: admin | Password: 123456. Alternative Accounts: Admin 2: Username: 888888 | Password: 888888. Hidden User: Username: default | Password: default.
Firmware-Specific (v3.1 to v7.x): Try 9999@ or leaving the password field blank. Password Recovery Options
If the standard defaults do not work, you can regain access using these methods:
Security Questions: If you configured these during setup, click the "Forgot Password" link on the login screen and answer your set questions to create a new password. For most current Dahua DVR models, there is
Dahua Config Tool: Download the Dahua Config Tool on a computer connected to the same network. This software can often trigger a password reset via an XML file exchange with Dahua Support or by scanning a QR code on the screen.
Physical Reset Button: Many modern Dahua DVRs/NVRs have a small button on the motherboard. To use it, disconnect the power, press and hold the button, reconnect the power, and continue holding for about 10–30 seconds until you hear a beep.
Daily Password Generator: For certain older versions, you can use a "Daily Password" based on the current date shown on the DVR's on-screen display. You must use a third-party generator tool found on community sites like the CCTV Super Password Generator.
CMOS Battery Removal: As a last resort, removing the CR2032 coin-cell battery from the motherboard for at least 60 seconds may reset the system clock to factory settings, which can sometimes revert the device to a known default state.
Note: Performing a factory reset via the physical button will often erase all configuration settings, though recordings on the hard drive are typically preserved.

What Is Dahua Default Password And How to Keep Passwords Securely
In the world of security surveillance, Dahua Technology stands as a global giant, manufacturing millions of Digital Video Recorders (DVRs) and IP cameras for homes, businesses, and government facilities. Whether you are a security installer, an IT administrator, or a business owner who has just inherited a legacy surveillance system, one of the most common hurdles you will face is the Dahua DVR default password.
This article provides a deep dive into what these default credentials are, why they exist, the critical security risks they pose, and—most importantly—how to access, change, and secure your device.
Because Dahua manufactures for third parties, here is a quick cheat sheet:
| Brand | Default Username | Default Password |
| :--- | :--- | :--- |
| Dahua (New) | admin | [Blank] |
| Dahua (Old) | admin | admin |
| Lorex (Dahua OEM) | admin | [Blank] (or admin for very old units) |
| Amcrest (Dahua OEM) | admin | admin |
| EmpireTech | admin | admin |
| Armcrest | admin | [Blank] |
Under GDPR compliance pressure and global cybersecurity mandates (such as the U.S. NDAA and FCC requirements), modern Dahua devices (firmware V4.0 and later, and specifically the "Smart" series) implemented a forced password reset mechanism.
Upon the first boot, the device detects the default state and forces the user to define a complex password (minimum 8 characters, combination of letters and numbers) before the GUI or web interface becomes accessible.
