Has anyone got a Messoa NDR891-HP5 dome / ip camera? I have just been given one which apparently has no working option to change the default username / password (menu option is there but when I click add/modify nothing happens). I have looked at the Messoa website and the latest firmware (which is for a slightly different PRO model) displays an error message "invalid file format" if I try and flash it. There is no firmware available on the site for the HP5 model, - the existing version is AP_01-00-62-18_MS02. Just wondering if anyone has a different version suitable for my camera which might overcome the password problem? I can't risk using it with the default username / password still available!
