Keep doing what they are doing - solid quality, excellent support, rockbottom price.
The Pelco reference is fascinating here because they were famous for top customer service / loyalty, before Schneider acquired them.
From what I have heard about the Pelco fall, the main driver was Schneider cost cutting. Not surprisingly, white glove customer service is really expensive, even back in those days when the average prices were dramatically higher than today's Hikvision.
That's what I am skeptical about with Hikvision. It's one thing to sell boxes for cheap. Take the Ubiquiti model. It works but the tradeoff is clear, you will get rockbottom prices but don't expect to speak or see a human being from Ubiquiti.
Eventually when a company gets concerned about making a profit, high touch customer support is a top target for getting cut, because it's so expensive and, because it is inherently local, it is not something that can be outsourced or done for cheap in China.
