Q: Will an MHK DVR password reset delete my footage? A: No. A standard factory reset or password recovery clears only user settings and login credentials. The hard drive’s video data remains intact. Only a full hard drive format or a “factory reset including HDD” option (rare) will erase footage.
Q: How do I reset my MHK DVR password without a monitor? A: If you cannot connect a monitor, you need to use the Windows Config Tool if the DVR is on the network, or perform the hardware jumper reset blind (follow the steps exactly by timing LEDs or beeps). The easiest way is to temporarily borrow a VGA monitor.
Q: Why doesn’t the email reset link arrive? A: Check the DVR’s SMTP settings. Many MHK DVRs only work with outdated security protocols. Try setting up an email again after logging in. Alternatively, the reset email may be in your spam/junk folder.
Q: Can I reset the password remotely via the mobile app? A: No. Mobile apps (like NVMS7000 or SuperLive Plus) do not include password reset functions for security reasons. Reset must be done locally or via the Windows tool.
Q: My MHK DVR says “User is locked” after too many tries. A: Unplug the DVR for 30 minutes, then plug back in. This clears the temporary lockout counter. Then attempt one of the reset methods above without repeatedly guessing passwords.
⚠️ High risk of bricking if wrong firmware.
For some models, you can reset the password directly through the device's menu:
Most budget-friendly DVRs (including MHK models) come from the factory with a default master password or a "super password" generated by the manufacturer. This is designed for technicians to unlock the unit if a user locks themselves out.
1. Try Common Default Passwords Before you try anything complex, try these standard default passwords. It is surprising how often these work even on "used" systems:
2. Use a Master Password Generator If the defaults don't work, the system likely uses a dynamic master password based on the current date and time displayed on the login screen.
Note: This temporary password usually only works once. Once you are in, go immediately to the User Settings to create a new password you can remember.
If you are comfortable with electronics and firmware, you can download the original firmware for your specific MHK DVR model from a trusted source (official site only—avoid third-party firmware that may contain malware).
Process:
Risk warning: Flashing the wrong firmware can permanently brick your DVR. Only use this if you have exact model and revision match.
| Method | Difficulty | Success rate | Data loss risk | |---------------------------------|------------|--------------|----------------| | Default passwords | Very easy | Low | None | | Backdoor account | Easy | Low | None | | Unlock code generator | Medium | Medium-High | None | | CMOS battery removal | Medium | Low-Medium | High (config) | | Firmware reflash | Hard | Medium | Very High | | Serial console | Expert | High | Medium |
If you can still access the DVR via remote viewing app (like EasyVMS or iDMSS), sometimes you can change the local password from within the app under “Device Settings” → “Modify Password”. That’s often the easiest overlooked method.

Getting locked out of your Ming Hong Kai (MHK) digital video recorder (DVR) can be a frustrating hurdle in maintaining your home or business security. Whether you've forgotten a custom password or the default credentials aren't working, several reliable methods exist to restore access. 1. Try Common Default Passwords mhk dvr password reset
Before attempting a hard reset, try the standard factory credentials. Many MHK and similar unbranded H.264 DVRs ship with predictable default logins. Usernames: admin, Administrator, or 888888
Passwords: 12345, 123456, 000000, or simply leave the field blank.
Specific MHK Default: Some MHK models may use 123456 or admin as the default password. 2. Hard Factory Reset (Physical Method)
If software defaults fail, a physical reset is often the most direct solution. This typically reverts the device to its original factory state, including the default password.
The Reset Button: Power off the DVR and locate a small button or pinhole labeled "Reset" on the back or the motherboard inside the casing. Press and hold it for 15 to 30 seconds while powering the unit back on.
CMOS Battery Removal: For older models without a reset button, you can try removing the small CMOS coin battery from the motherboard for several minutes. This may reset the system clock and sometimes clears the local password database.
Jumper Shorting: Some boards have two pins labeled "G1" or "TP". Briefly shorting these with a conductive tool (like tweezers) while powering on can trigger a factory reset. 3. Date-Based Super Password
Many H.264-based DVRs use a "Super Password" algorithm that generates a master override code based on the current system date displayed on your monitor.
Check the Date: Note the exact date (DD-MM-YYYY) shown on your DVR's login screen.
Generate Code: Use a Super Password Generator tool or app (often available on CCTV forums or from the manufacturer).
Input Code: Enter the generated code into the password field. If successful, the DVR will prompt you to create a new admin password. 4. Technical Support Recovery
If the above methods do not work, you may need to contact MHK Industrial Park technical support directly for a unique reset code. How to Reset a NVR Without Password: Easy Guide - eufy US

Locate and remove the small silver coin battery (CR2032) for about 2 minutes.
Reinsert the battery and power on. This often resets the system date to a factory default (like 01-01-2000), allowing you to use that date's specific master password. Method 3: Factory Default Credentials
Once reset, try these common default combinations to log in: Username: admin Password: (leave blank), 123456, admin, or 12345.
Important: A factory reset typically restores system settings but does not delete recorded video footage stored on the hard drive.

Complete Guide to MHK DVR Password Resets Resetting an MHK DVR password typically requires using default credentials, generating a date-based "super password," or performing a physical factory reset. Because MHK often utilizes standardized Chinese-manufactured firmware, many universal H.264 DVR recovery methods are effective. 1. Initial Attempt: Default Login Credentials
Before trying complex reset methods, attempt to log in with the manufacturer's default settings. If the system has never been customized, these common credentials may work: Username: admin Password: 12345, 123456, or leave it blank (empty). 2. Using a "Super Password" Generator
Many MHK units use a security algorithm based on the system's current date. You can generate a temporary Super Password to bypass the lock.
Note the System Date: Check the date and time displayed on your DVR's live monitor screen.
Download a Generator: Use a tool like GenSuperPassword.exe or a CCTV Super Password app.
Input Serial Number/Date: Enter the exact date shown on the DVR (e.g., 2024-05-04) into the generator.
Enter the Code: Use the generated code in the DVR's login field to gain access and immediately change the admin password. 3. Physical Hard Reset Methods
