How to Reset DVR to Factory Default Without Password: Step-by-Step Guide

Reset methods by manufacturer

• General method:

  • Navigate to Setup > System > Maintenance > Load Default or similar menu options
  • Select settings to reset, but do not check System boxes to avoid resetting the password

• Samsung DVRs:

  • Use the remote control: Press Freeze > Alarm > Freeze > Alarm > Freeze > Return quickly
  • Or hold down the MODE and PTZ buttons for over 5 seconds
  • For models with front panel buttons: Press Mode and CH 2 together for 5 seconds

• HIKVISION DVRs:

  • Use Search Active Devices Protocol (SADP) software to scan for the device and reset the password
  • Contact HIKVISION technical support for a security code or unlock file if needed

• Lorex DVRs:

  • Try default passwords: admin/000000 for LHV/LNR models, admin/00000000 for LHA/LNK models
  • Use the reset button on the system board (location varies by model)

• Swann DVRs:

  • Use the device config tool on a laptop connected to the same network as the DVR
  • Reboot the DVR, click "forgot password" at login, enter the DVR's MAC address as the password (replace dashes with colons)

General reset precautions

• Resetting to factory defaults typically erases recording schedules, alarms, and personalized settings
• Most reset methods do not delete recorded footage
• Custom user accounts and passwords often remain intact after a reset
• If you need to format the hard drive and erase footage, select 'Format HDD' when resetting

Alternative solutions

• Check the user manual or manufacturer's website for default passwords
• Common default combinations: admin/admin, admin/123456, admin/secure, admin/password
• For H.264 DVRs, try using a password key generator based on the DVR's current timestamp

When reset methods fail

• Contact the manufacturer's customer support for a superuser password or specific reset instructions
• If the footage is critical, consider contacting a professional data recovery service
