The default password for Dahua DVR (Digital Video Recorder) systems can vary depending on the specific model and firmware version. However, for many Dahua devices, the default admin username and password are often:
| Device Age | Default Password? | Action Required |
|------------|------------------|------------------|
| Pre-2019 (old firmware) | admin / admin | Change immediately – high risk |
| 2019–present | None (forced setup) | Use the password you created; otherwise reset device |
| After factory reset | None (forces new password) | Use ConfigTool or contact support |
Final Recommendation: If you are trying to access a Dahua DVR and admin/admin does not work, the device is either modern or has been secured. Do not attempt brute force – use the physical reset or Dahua's password recovery tools.
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.
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. dahua dvr default password

The Dahua DVR default password (admin/admin) is a necessary evil for setup but a critical vulnerability in production. If you are still using it — or aren’t sure — stop what you’re doing and change it now. Surveillance systems are only as secure as their weakest link, and all too often, that link is a password written on a sticker or left unchanged since installation.
Remember: Security isn’t just about watching. It’s about controlling who watches back.
