Wow, this was a very informative thread. I've read the whole 1722 posts with great interest and learned SEVERAL things I did not know along the way. Thanks

@Frank van der Heide and everyone else for kindly sharing your time and knowledge with other member of this awesome community.
I own a Dahua OEM camera with the majority of specs identical to the SD59225U-HNI, including StarVis sensor and IVS. The only two diferences are: 1) only 20x zoom and 2) no IR (my choice, the other local OEM model had the same specs AND IR built-in). So I guess, if Dahua would sell the same camera it would be something like a SD59220U-HN. The firmware on my camera was localized by the vendor (Intelbras), but looks almost exactly the same as the newer 2017 version firmwares you guys have posted pictures above.
Now, by reading other posts here on IPCT, if I understood things correctly, I believe Dahua cameras' onboard permanent flash memory is partitioned into several separate partitions, one for the WEB interface, one for the PTZ code, another for the optics, etc. If my assumptions are correct, I suppose it's possible to replace the localized WEB interface with DAHUA's. I would like to make my camera work as much as a DAHUA branded one, because it's much easier to obtain information here than with the local OEM. I've seen another post here where a fellow member posted about some sort of firmware toolkit. Does anybody know if the thing I'm thinking about is even possible?
I've been in IT for the last 30 years and am fairly experienced with networks, operating systems (mostly MS and Apple, but some Linux knowledge as well), home automation and (very) basic electricity and electronics as well. I would therefore appreciate any input you master gurus would like to share on this subject.
PS: By the way, the camera mount that came with my camera had the same problem some of you guys posted about here. Once it was mounted, it was tilted somewhat outwards and up to the sky... I "fixed" the problem by sawing, re-soldering and re-zincing the pole end.
