To be honest I'm quite impressed with these "cheap" systems from China. I did look at the Avigilion 29mp cameras etc. Great quality but low frame rate and not compact enough etc. For residential use, the "cheap" cameras from China work just fine for me
Not sure what peoples beef is really, is it affecting your business as a cctv installer? Times change in any industry, keep up or you'l be left behind, or diversify.
I'm sure theres more to it than this, but above is one point of view.
