Does ONVIF Device Manager show that the ONVIF port (in the URL at the bottom of the Identification page) is the same as the HTTP port?
In some cameras they differ, some they do not.
you sure your ACTI is ONVIF?
change manufacturer to customized and specify RTSP URI manually.. you'll have to obtain the RTSP URI from your own research w/out the ONVIF tool, test it with VLC first and make sure it works.
If ODM does not find the camera automatically, and it's IP address is on the same range as that of the PC, the camera is not ONVIF compliant.i entered that address and i entered it again with the forward slash that onvif manager automatically puts in the address bar
FYI, for any of your Dahua cameras use the manufacturer: Private and not ONVIF.
Dahua is not on the list because these can be rebranded and resold under other labels.
