@Wildcat_1 ,
Was Dahua able to get the issues worked out that you ID'd and also how has the performance of the camera been over the last 6 mos or so. I'm considering picking2 of these up to deploy. I'm also curious about your thoughts on it's nighttime color performance when compared to IPC-HFW5849T1-ASE-LED?
In answer to your question, YES, this camera is still a strong candidate for sure BUT remember it has use cases that are very different than that of the 5849TI and the 5849 is a fixed lens. If you have a use case that the dual lens with PTZ & TZ can fill then this camera is still amazing. The image really is tack sharp as I showed on the 4MP + 4MP. It has been updated to 8MP + 4MP flavors now as well. The only other thing to remember is that for the most part Dahua themselves are selling this under the special project / larger business category therefore although you can still pick these up through certain resellers, they are generally sold in bulk for larger deployments.
The one thing to remember about the 5849TI is that while you gain from the f1.0 as I showed in my review, you do have a short drop-off due to a more shallow DOF caused by the sensor optic pairing. Anti Alias was also a big impact to that cam although I'm glad to say that the latest beta FW (while still having some issues I reported) improves on this a lot.
So in summary, if you have a static scene (no need for PTZ functionality including PTZ activations) and want / need good color at night (without lots of additional light) then the 5849TI is a good choice. If however you don't mind extra light, don't mind the bulkiness this camera brings (it is big), have a need for PTZ functionality, want the luxury of dual, 'regular' optics (not specialized like thermal, full time IR sensors etc), need IR, and like tack sharp images then for the
right applications/deployments this cam still has a place IMO.
If you do want to dual camera the solution then as Kobe mentioned you absolutely could throw a 7x42 Ultra in the mix (still love that series) + a 5849 BUT again this all depends on your needs, installation requirements, lighting on scene, distance to target, special application requirements (face detection, recognition, LPR etc).
