What with firmware breaking things in various makes and models, I'm just reporting that the process laid out in the sticky how-to for the subject model works, at least for what I got.

I put up a new/refurbed unit yesterday and followed the sticky steps. Firefox easier than Chrome for configuring. Wired ethernet more reliable than wireless; wireless kept dropping the stream after a minute or two.

Here's the firmware load on my unit, as-delivered:
System Firmware Version 1.4.1.9
Application Firmware Version 2.11.1.10
Plug-In Version 3.0.0.1
I'm in "ain't broke, don't change it" mode here.

I'm just a user with no particular expertise in these cameras and integration other than following directions but thought a recent experience might be useful to someone.
Good luck to all.
