You are mistaken...
Most of us here know that the Dahua and Hikvisions of the world do not cater to the "consumer" market - their target audience is professional installers, so we are considered "prosumer" and we are fortunate to get our hands on these types of cameras and NVRs instead of consumer grade junk and not having to go thru professional installers to get quality gear. Now the downside is we get them at a discount and without manuals and Dahua support and thus are on our own to figure it out. And we are just fine with that! That is what forums like this are for!!!
Some here prefer Hik and some here prefer Dahua, but to say ignore the comments of valuable members here is short-sighted. You have to recognize they are not in business to compete with the Rings and Arlos of the world.
Personally, I have found Dahua and even Hik gear to be more intuitive than any big box store, consumer grade all-in-one kit that I have had prior to becoming educated on cameras. After playing with both, I prefer Dahua over Hik, but to each their own and YMMV.
So either go with consumer grade stuff or "suffer" with no support for better cameras, but end up with a better system after playing and learning it....or pay a Dahua or Hik authorized installer to set up the system...
