I installed said intercom in my firm. When i wanted to change http port so i can manage it (remotely) and add it to my firms nvr at another location, it won't change. I go to network and ports. I changed http port to 90. It restarted it self and nothing. I still access it with port 80, even tho in the settings it displayed http port 90. It's like it saved changed port but didn't implement it. Does anybody have any idea what can i do to really change port for http?
