I notice the preview only works for me on Microsoft Edge and is there any settings to get back channel http://192.168.1.XX/cgi-bin/snapshot.cgi?channel=0
IPC-HDW4231EM-AS Same problem i try to go back to older firmware DH_IPC-HX5X3X-Rhea_Eng_P_Stream3_V2.622.0000000.31.R.180813.bin and get "The upgrade package version is too low, failed to upgrade! Some functions of the device has been disabled, restart device now?"
I tried to use TFTP but i didnt work. Please let me know how you roll back this firmware. My problem is that this firmware is not broadscasting on http://192.168.1.XX/cgi-bin/snapshot.cgi?channel=0 only on http://192.168.1.XX/cgi-bin/snapshot.cgi?channel=1. Also the preview is not working...
