Azy2333 0 Posted May 31, 2016 Hi Everyone, Sorry if this is in the wrong section, I'm having an issue please advise. I've forgotten my admin password for my DVR. Model number: MD404EN-AHD Below is a picture of what the box looks like from the front. I've looked online and I cant find a master password or even any tricks off holding buttons etc. will i need to open it up and reset the BIOS? please could anyone help with this issue. Thanks in advance, Regards Share this post Link to post Share on other sites
t310483317 0 Posted June 1, 2016 I take it when you say you have forgotten it then you changed it from default? If not some standard ones you could try if it was still default: 000000 123456 admin NULL 12888 1234 12345 no password just enter username and click login? If none of these work it might be worth powering off the DVR and unplugging it then opening the cover, removing any small watch battery(s) you can see - plug it back in and start the system up for about one minute, then again shut it down and unplug and add the battery(s) back in. And if that doesn't work then depending on your DVR you could try networking and using telnet to access into it remotely. Share this post Link to post Share on other sites
