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.
