peter4sks 0 Posted April 20, 2015 Hi,, Sounds like the BIOS battery is dead in the DVR. It has probably reset to the Default password. Replace the BIOS battery and try the default Password Peter Share this post Link to post Share on other sites

peter4sks 0 Posted April 23, 2015 Even if it's a new DVR it might've been on a shelf somewhere for a long time. If changing the battery doesn't work then try checking the solder on the battery connection. Share this post Link to post Share on other sites
tomcctv 190 Posted April 23, 2015 Hi. Forget battery problems .... You have a dahua Can you list admin and passwords you using Also if you can't log in remote again it's not a battery problem Did you port forward the recorder .... Are you using internal or external IP to view recorder Also what is the name of viewing software for PC and smart phones Share this post Link to post Share on other sites
