Email him (Andy). He can get you virtually anything Dahua makes, even the very most expensive items. He just doesn’t list them because of the limited market for those types of items. When I bought my NVR from him, there were two models I wanted a price on. One was over $600, so I went with the one around 300 since the more expensive one was overkill for my needs. I suggest you go on the international Dahua website, scroll to NVRs and see what they have before reaching out to him.
