Got my very first camera (Hikivision 3MP dome) from B&H Photo. That was important to me, as they're an authorized reseller, which made me eligible to contact Hikivision support directly. The two times I tried to do that, their support was no help. Ended up finding the solution on the forum here.
All of my cameras since then have been Dahua Starlight turrets. AFAIK, they're only available via AliExpress. I bought 2 from a no-name store (I really wanted them pronto), and the rest I've purchased from the store below. That store is run by Andy (
@EMPIRETECANDY), who has spent a crazy amount of time supporting forum members here (both with getting them the cameras they need, as well as escalating tech support stuff that the forum members here couldn't figure out). He ships via DHL also. It's amazing how fast they can arrive here in the US after they ship...

Buying from Ali, I know I'm forgoing official Dahua support, and if I need any warranty work, it's on my dime to ship back to Andy, but for the price, it's worth it for me. Although technically I haven't seen the US price for the specific model cameras I bought since they're not for sale here yet, but compared to some other models that B&H Photo is reselling, there''s definitely a big markup involved.
