Which brands have the most price advantages: Tiandi Ye Wei, Dahua, Hikvision, Jingyang and Hanbang Hi-Tech.

In terms of quality, Shanghai Kang and Dahua are neck and neck, and Shanghai Kang has a little more shipments, which are the strongest. At this point, there is not much difference between the two companies in terms of level and materials. For example, compared with China Mobile and China Unicom, domestic brands buy Haikang Dahua.

Haikang faces more big customers, so he is a bit arrogant, his service is a bit lacking, and things are more expensive. If I choose Dahua from an economic point of view, because Dahua's service is better and the cost performance is higher.

Vegetables and radishes have their own tastes. Generally speaking, with so many brands put together, it is no problem to choose Dahua or Haikang.
