Several times a month we see questions along these lines:
"I've forgotten the password for my Q-See DVR. How can I reset / recover it?"
"I've purchased / found / been given a Q-See DVR and it has a password. How can I clear it?"
When this question arises, it's too late for us to point out that all important passwords should be written down on paper and kept in at least one safe place. Passwords are easy to forget, and easy to lose when a single keystroke on a PC or a bad block on a disk can destroy the file containing all your passwords for everything.
Q-See as a company believes in strong security. This is one of the valuable features you pay extra for when you buy Q-See as opposed to a generic DVR. They deliberately, by design, make it extremely difficult to get into a Q-See DVR without the password. This makes that DVR and its contents completely useless to anyone who steals it or finds it in a second-hand store. This is as it should be with a device intended for security purposes.
All information we have -- and this question has been asked for quite some years -- indicates that there is no customer "back door" into Q-See DVRs. There's no back door even for us technomages with access to hardware troubleshooting tools. There's no JTAG header boot-time magic, no universal override password, no chip swap, no firmware reload to clear passwords, no jumper on the main board that can be shorted to clear everything.
The only way to unlock a Q-See DVR is with the assistance of Q-See Customer Service. The DVR must be registered on the Q-See site first, then they will assist.
