Poor choice of port, on my part, to serve as an example for changing the HTTP port from 80. I was talking about changing the HTTP port, not the command and control port.
Thanks for your input.
True, but the point is to secure login credentials. I wish the video stream was served encrypted too, but these units don't seem capable of that. Sloppy programming, if you ask me. This is the best we get with these HIKVISION NVR's.
Figured this one out!
Looks like the playback controls are hard-coded to operate on the HTTP port configured in the NVR, whether or not you're logging in via HTTPS. When I began forwarding both the HTTPS and HTTP ports through the firewall, playback and live view worked! So, HTTPS is used...
Did you ever figure out a solution to your issue here? I'm having the same problem and I'm afraid I'm stumped. I haven't been able to find any information elsewhere to lead me to a solution. :(
