Answering my own question (just shows you have to do things yourself usually). I managed to get the /etc/passwd file from this DVR, it's web interface is flawed in that you can grab most things from the filesystem by using relative paths. So I managed to grab the root password, ran through John the Ripper and got the root password (I won't post it here) In the /mnt/mtd/Config folder is two password files Account1 and Account2 (which I suppose it a backup). For resetting the admin password I used SED to substitute the password I had used for a blank one. eg. Make a backup: cp Account1 Account1- cp Account2 Account2- sed /s/oldhashedpassword/tlJwpbo6 Account1 sed /s/oldhashedpassword/tlJwpbo6 Account2 Resulting structure: "Group" : "admin", "Memo" : "admin 's account", "Name" : "admin", "Password" : "tlJwpbo6", "Reserved" : true, "Sharable" : true Reboot and you can log in with blank password again. (I'm no hacker, but this was a bit too easy).

Hi all, I bought a CNM Secure CCTV system in Dec 2011 and used it for a while. But then decided it didn't do what I wanted, so took it down. I want to sell it on to my father but when I came to check it was still working the other day I couldn't remember any of the passwords. I've emailed CNM Secure and Think CCTV where I bought it and neither have responded. This strikes me as very poor customer service and they have lot any future sale from me. I see that Maplins will send you a generated master code if you bought your DVR from them, but I didn't sadly. Does anyone know how I can reset this system to factory state? Looking at the unit it seems all the configuration information is stored in flash memory, so removing the coin cell and blanking the hard disk hasn't helped at all. I can provide proof of purchase if needed, I'm not selling on some hooky gear. Cheers.
