Default DVR Passwords (The "Backdoor" List)

If you are looking to regain access to a DVR system because the password was lost or the device was purchased second-hand, you are likely encountering one of the many generic "admin" defaults used by OEM (Original Equipment Manufacturer) devices. Many budget DVRs are rebranded units manufactured by a handful of companies (like Dahua or Hikvision) or use similar legacy firmware.

Here are the most common default username and password combinations:

1. The Super User (Most Common):

   • Username: admin
   • Password: admin (or leave the password field blank)

2. The Numeric Defaults:

   • Username: admin
   • Password: 12345 or 123456 or 12345678
   • Username: admin
   • Password: 000000 or 00000

3. Specific Manufacturer Defaults:

   • Hikvision: Username: admin / Password: 12345
   • Dahua: Username: admin / Password: admin
   • Swann: Username: admin / Password: 12345 (Older models often used admin/admin).
   • Lorex: Often uses admin / admin or 000000.
   • Night Owl: Username: admin / Password: 000000 or 123456.

How to Identify Your Device If the above do not work, check the sticker on the bottom or side of the DVR unit. Look for a "Serial Number" (S/N) or a MAC address. You can often use the "Forgot Password" feature in the login interface, which will generate a file or a code. Sending that code to the manufacturer's technical support (along with proof of purchase) is the official method for resetting modern, encrypted DVRs.

Note: Accessing a DVR system that you do not own or have authorization to access is illegal. This information is intended for system administrators and owners performing maintenance on their own hardware.

Managing a Digital Video Recorder (DVR) requires understanding its security protocols, which typically rely on a combination of default manufacturer credentials and customized user passwords. Common Default Credentials

If you are setting up a new device or have never changed the factory settings, the most common default usernames and passwords used by major manufacturers like Dahua, Hikvision, TVT, and Amcrest include: Username: admin (almost universal) Common Passwords: admin 12345 or 123456 000000 or 111111 password or secure Leave the field blank How to Reset a Forgotten Password

If the default credentials fail and you are locked out, you can regain access using several industry-standard methods:

Getting locked out of your Digital Video Recorder (DVR) is a common headache, whether you’ve forgotten a custom password or you're setting up a second-hand unit. Most systems offer multiple recovery paths ranging from "master" passwords to hardware resets. Common Default Login Credentials

Many DVRs ship with universal default settings. If you haven't changed yours, or if you've recently performed a factory reset, try these common combinations Default Username Default Password 4321 or 1111111 Generic H.264 123456, 111111, or [blank] Hoosier Security How to Recover or Reset a Lost Password

If the defaults don't work, you can typically regain access using one of these methods: Software-Based Reset (Hikvision/Dahua)

: Modern units often feature a "Forgot Password" button on the login screen. You can scan a

with a mobile app (like Hik-Connect) to receive a temporary verification code via email. Master Password Generators

: For older "no-name" or H.264 DVRs, some tools can generate a master password

based on the date and time currently displayed on the DVR's screen. Physical Reset Button : Many recorders have a physical reset button

inside the casing or on the back panel. Pressing and holding this while the unit is powering up usually restores all settings, including the password, to factory defaults. Battery Removal

: On some older models, removing the small CMOS battery from the motherboard for a few minutes can clear the system memory and reset the clock , which sometimes reverts the password to the default. Security Tips for Your DVR Change Defaults Immediately : Standard logins are a major security vulnerability; change them

to a strong, unique alphanumeric password as soon as the system is online. Configure Recovery Options : Set up a reserved email address

or security questions in the user settings menu while you still have access. Enable Permissions

: If creating multiple accounts, ensure only the "admin" user has the authority to change system settings or reset passwords. Do you have the brand and model number of your DVR so I can provide specific reset instructions?

Here’s a short, engaging piece of content on the subject "DVR Login Password" — written to be useful and interesting for someone setting up or troubleshooting their security system.

Title: The One Password You’ll Either Thank Yourself for — or Curse at 3 A.M.

You just installed a DVR for your security cameras. The feeds are live, the hard drive is spinning, and you’re feeling like a tech pro. Then comes the prompt:

“Set admin password.”

Most people type something quick — 123456, admin123, or their pet’s name. And that’s where the drama begins.

Method 2: The Unlock Pattern (Touchscreen DVRs)

If your DVR has a touch screen interface, many manufacturers default to a pattern unlock.

• Action: Try drawing a "Z" or an "L." If that fails, look for a "Pattern Unlock" option that lets you revert to password entry.

1. Purpose

Securely control access to the DVR’s live view, playback, settings, and exported footage. Prevents unauthorized configuration changes or video access.

Method 5: The Serial Number Reset File (Advanced)

Brands like Hikvision and Dahua do not have physical reset buttons. They require a password reset file.

1. On the DVR login screen, click "Forgot Password."
2. The DVR will show a long string of characters (a "Security Code" or "XML request").
3. You must email that code to the manufacturer or use their official "Reset Tool" (SADP Tool for Hikvision).
4. They will email you back a .xml or .dat file.
5. Save this file to a USB flash drive.
6. Plug the USB into the DVR and click "Import." The password resets to default.

For administrators: recommended configuration checklist

• Change default admin account name if possible.
• Enforce complex password policy (minimum length, complexity, no reuse).
• Disable unnecessary services (Telnet, FTP, UPnP).
• Close or avoid port forwarding for management ports (HTTP/HTTPS/RTSP); use VPN.
• Apply vendor-recommended TLS/HTTPS for web interfaces.
• Limit admin access by IP/address or VPN only.
• Implement role-based access: separate viewer vs. admin accounts.
• Schedule automatic firmware checks and patching procedure.
• Conduct periodic penetration testing or vulnerability scans on DVR subnetwork.

Threats and risks

• Default or weak passwords enable unauthorized access to live feeds, recorded footage, and device settings.
• Attackers can pivot from compromised DVRs to internal networks, exfiltrate footage, or disable recording.
• Exposed web interfaces or improperly forwarded ports increase remote attack surface.
• Brute-force and credential-stuffing attacks are common against DVR admin interfaces.
• Some DVR firmware contains vulnerabilities that, combined with weak credentials, permit full takeover.
