What Is the Default Password of Dahua DVR?

If you’ve just unboxed a new Dahua DVR or are troubleshooting an existing one, you’ve probably asked: “What is the default password of Dahua DVR?” It’s a common question—and for good reason. Getting access to your DVR is the first step to setting up your surveillance system, viewing footage, or adjusting settings. But while the default password might seem like a simple detail, it’s actually a critical part of your system’s security.

Dahua Technology is one of the world’s leading manufacturers of video surveillance equipment. Their DVRs (Digital Video Recorders) are widely used in homes, businesses, and public spaces because of their reliability, advanced features, and affordability. But like any internet-connected device, Dahua DVRs can be vulnerable to cyber threats—especially if left with default settings.

In this guide, we’ll walk you through everything you need to know about the default password of Dahua DVR, why it matters, and how to secure your system properly. Whether you’re a first-time user or a seasoned installer, this article will help you protect your investment and your privacy.

Understanding Dahua DVR Default Credentials

When you first power on a Dahua DVR, it usually comes with pre-set login credentials. These are known as “default credentials,” and they’re designed to let you access the system right out of the box. The most common default username is admin, and the default password is often either blank (no password) or 123456.

For example, many Dahua DVR models—such as the DH-XVR5104HS-S2 or the XVR7108-4K—use:
– Username: admin
– Password: (leave blank) or 123456

Some newer models or firmware versions may prompt you to create a password during the initial setup, effectively removing the risk of a universal default. However, older units or those with outdated firmware still rely on these weak defaults.

It’s important to note that Dahua has been gradually improving its security practices. In recent years, they’ve introduced mandatory password creation during setup for many devices, especially those connected to the internet. But if you’re working with a used or older DVR, there’s a good chance it still uses the old defaults.

Why Default Passwords Are a Security Risk

Leaving your DVR with the default password is like leaving your front door unlocked. Hackers actively scan the internet for devices with known default credentials. Once they gain access, they can:
– View live camera feeds
– Delete or alter recorded footage
– Use your DVR as a gateway to attack other devices on your network
– Install malware or ransomware

In 2017, a major security flaw known as the “Dahua Backdoor” was discovered, allowing attackers to bypass authentication on certain models. While Dahua has since patched many of these vulnerabilities, devices with default passwords remain high-risk targets.

How to Check Your DVR’s Default Password

If you’re unsure what the default password is for your specific Dahua DVR model, here’s how to find out:

1. Check the user manual: The default login credentials are usually listed on the first few pages.
2. Look at the label on the device: Some DVRs have a sticker on the back or bottom with the default username and password.
3. Visit Dahua’s official website: Use their support section to search for your model and download the latest manual.
4. Contact Dahua support: If you can’t find the info, reach out to their customer service with your model number.

For example, the Dahua DH-XVR1A04 model uses:
– Username: admin
– Password: (blank)

While the Dahua XVR5108HS-S2 may use:
– Username: admin
– Password: 123456

Always verify with your specific model, as defaults can vary.

How to Change the Default Password on Dahua DVR

Changing the default password is one of the most important steps you can take to secure your Dahua DVR. Here’s a step-by-step guide to help you do it safely and correctly.

Step 1: Access the DVR Interface

First, you’ll need to log in to your DVR’s interface. You can do this in two ways:
– Locally: Connect a monitor and mouse directly to the DVR.
– Remotely: Use Dahua’s mobile app (like DMSS) or a web browser to access the DVR over your network.

To access via web browser:
1. Find your DVR’s IP address (usually printed on the device or found in the network settings).
2. Open a browser and enter the IP address (e.g., http://192.168.1.108).
3. Enter the default username (admin) and password (blank or 123456).

Step 2: Navigate to User Settings

Once logged in:
1. Click on the Main Menu (usually a gear icon or “Config” button).
2. Go to System > User Management or Account > User.
3. Select the admin user account.

Step 3: Create a Strong Password

Now, it’s time to set a new password. Here’s what to keep in mind:
– Use at least 8 characters.
– Include uppercase and lowercase letters (e.g., A, a).
– Add numbers (e.g., 1, 2, 3).
– Include special characters (e.g., !, @, #, $).
– Avoid common words like “password” or “admin.”
– Don’t use personal info like your name or birthday.

For example, instead of “123456,” use something like “D@hua2024!” or “S3cur3V!deo”.

After entering your new password, confirm it and save the changes.

Step 4: Log Out and Test

Log out of the system and try logging back in with your new credentials. This ensures the password change was successful.

Pro Tip: Use a Password Manager

To avoid forgetting your new password, store it in a secure password manager like Bitwarden, LastPass, or 1Password. This way, you can generate and save complex passwords without the risk of losing them.

Best Practices for Dahua DVR Security

Changing the default password is just the beginning. To fully protect your Dahua DVR, follow these best practices:

1. Enable Two-Factor Authentication (2FA)

If your DVR model supports it, enable two-factor authentication. This adds an extra layer of security by requiring a code from your phone (via SMS or an authenticator app) in addition to your password.

To enable 2FA:
1. Go to System > Security > Two-Factor Authentication.
2. Follow the on-screen instructions to link your phone.
3. Save the backup codes in a safe place.

Not all Dahua DVRs support 2FA, so check your model’s capabilities.

2. Update Firmware Regularly

Outdated firmware can contain security flaws that hackers exploit. Dahua regularly releases updates to fix bugs and improve performance.

To update your firmware:
1. Visit Dahua’s official support site.
2. Search for your DVR model.
3. Download the latest firmware file.
4. Go to System > Maintenance > Upgrade on your DVR.
5. Upload the file and follow the prompts.

Always back up your settings before upgrading.

3. Disable Unused Features

Turn off features you don’t need, such as:
– Remote access (if you only view footage locally)
– FTP upload (unless required)
– Telnet or SSH (unless you’re an advanced user)

Each enabled service is a potential entry point for attackers.

4. Use a Strong Network Password

Your DVR is only as secure as your Wi-Fi network. Use a strong Wi-Fi password and enable WPA3 encryption if available. Avoid public or unsecured networks when accessing your DVR remotely.

5. Limit Remote Access

If you need remote access, use a secure method:
– Set up a VPN (Virtual Private Network) to encrypt your connection.
– Use Dahua’s DMSS app with a strong password.
– Avoid using third-party apps or services that may not be secure.

6. Monitor Login Attempts

Check your DVR’s login logs regularly to spot suspicious activity. Go to System > Log > Login Log to see who has accessed the system and when.

If you see failed login attempts from unknown IP addresses, change your password immediately and consider blocking those IPs.

Troubleshooting Default Password Issues

Sometimes, you might run into problems accessing your Dahua DVR—even with the default password. Here’s how to troubleshoot common issues.

Forgot the Password?

If you’ve changed the password and forgotten it, you’ll need to reset the DVR to factory settings. This will erase all recordings and settings, so use it as a last resort.

To reset:
1. Power off the DVR.
2. Locate the reset button (usually a small hole on the back).
3. Use a paperclip to press and hold the button for 10–15 seconds while powering on.
4. Wait for the system to reboot.

After resetting, use the default credentials to log in and set a new password.

Can’t Log In with Default Password?

If the default password isn’t working, possible reasons include:
– The DVR has already been configured by someone else.
– The firmware has been updated to require a password on first use.
– The device is part of a managed system (e.g., installed by a security company).

In these cases, contact the installer or Dahua support for assistance.

Locked Out Due to Failed Attempts?

Some Dahua DVRs lock the account after multiple failed login attempts. If this happens:
– Wait 15–30 minutes for the lockout to expire.
– Use a different device or network to try again.
– If the issue persists, perform a factory reset.
