Both maybe? :D I remember needing to that when setting up a DS-2CD2443G0-IW last week.
How are you changing the password? Is it longer than 16 characters?
For anyone wondering, the DS-1280ZJ-XS & CBXS mounts should work for this camera. I'm using this one from Amazon: https://www.amazon.com/gp/product/B071F3TXQT/ref=oh_aui_search_asin_title?ie=UTF8&psc=1
I've been slowly replacing my indoor cams with Hikvision cubes, DS-2CD2432F-IW and DS-2CD2442FWD-IW models. Would like to try one the one Mike posted above me.
According to the specs, the Hik should have a 78 degree FOV.

An IPC-HDW4231EM-ASE with a 3.6m lens has an 87 degree FOV.
IPC-HDW4231EM-ASE
Oddly, Dahua lists the focal length for the IPC-HFW1831E as 4mm, but with the same FOV as the 4231...
I haven't upgraded any of mine yet.
ETA: I checked the firmware on mine. The Hykamics are running V5.5.53 build 180730. The DS-2CD2432F-IW cams are running V5.4.5 build 170123.
