I doubt you are going to find anything like the Dahua prices from a non-Chinese vendor. All of the Chinese vendors benefit from massive economies of scale.
A Taiwanese vendor to look at is https://www.vivotek.com. I've got a few of them and they've been solid, despite not having many firmware releases. They are broadly available in the US.
I think the GeoVision (Taiwanese also) is close enough in price to comparable budget Dahuas. I just wish they had an equivalent of Dahua's higher quality models.
