If Hikvision were to ever fall behind on features, performance, or reliability, they would be dead quickly. This is due to the government ownership, that already makes them a no-go for many. If they have any major missteps in the future, it could be much more damaging for them, due to the government factor.
They already aren't the cheapest, and by far. Their Value Series is an affordable line for sure, but their Smart Series is world class and on par pricing wise, if not just a tad below the competition. They include more features for the dollar than many other brands.
The only other real, end to end, top to bottom competition is Axis and Avigilon. No one else is on their level. Avigilon is surely the best in class today, but Hikvision is a VMS away from closing that gap.
