The Eng-NTSC firmware update (General_IPC-HX3(2)XXX_Eng_N_V2.212.0000.0.R.20131206.bin) was successful for both my Dahuas: HDW2100N and HFW3200S. Thanks ilkevinli! Note: TCP/IP settings did not reset (i.e. did not revert back to static 192.168.1.108). I was nervous for a bit when trying to connect to that and it wasn't working!
