ONVIF user authentication is hard coded in the chip inside the cameras. You cannot disable it unlike the older Dahua cameras. I had the online tech disable it but it went right back.

I need it to stream live view photo/video to my Raymarine Axiom display for boat cameras without user log-in but this camera is hard coded to force you to log in with user name and password of admin/admin.

Yes, you can change the username/password for watching your property. You can hard reset if you forget password later.
