How to organize remote access to video recorder?

Question

Remote access

Good day.
I am writing because I did not find a solution in already created topics.
The essence is the following: there is a video recorder, there is a need to view the video remotely. How can this be organized?
The recorder supports online broadcasting, but how to connect to it? You need an Internet connection of the recorder, it is used as a server. How to connect to it?
Thank you in advance.
