Thanks again. I had scanned those two reviews you suggest but got kind of lost as I was already confused with the model numbers.
Also I'm interested in moving up to 8MP and from EMPIRETECANDY response to my question about the IPC-B58IR-ZE above, there doesn't appear to be a version with the new GUI (S3).

I would stick with the 4MP version unless you don't care about low light performance as the 8MP is on the same size sensor as the 4MP so the 8MP needs twice the light as the 4MP to produce a comparable image in terms of brightness.
The BR58 series does have the new GUI for the Z4E model (up to 32mm focal length) which would be too much for your needs, but you can see how it compares to the 4MP in lower light conditions which may or may not be an issue for you.
Mini-Review - 5842-Z4E-S3 AKA B58IR-Z4E S3 - Replacement to the 5842-Z4E (8MP on the 1/1.8" sensor)
Given the improvements that Dahua has made with the 5442 S3 series and the incredible night performance improvements, time to see if putting 8MP on the same size sensor results in a degradation or improved performance, so compliments of @EMPIRETECANDY we have one to do a side-by-side comparison...
