Dahua Lenses... DH-IPC-HDW4431C-A & 4300C

[badmop]

Any of you know if the DH-IPC-HDW4431C-A camera uses the same lens as the 4300C? camera? I swapped my 2.8mm lens in my 4300C to a 2.1mm and it is so much wider, it's amazing, it's not distorted any more than the 2.8mm and no black edges, or corners.

I'd like to swap the lens in the new 4431C when I get one, so I'm curious which lens it uses?

Thanks

where did you get the 2.1mm lens? was it an easy swap?
