It all goes back to what I said earlier, if you are going to play with prosumer level Ipcameras you have to learn basic networking skills and terminology. It is not difficult but requires a willingness to learn. When I came here in 2020 I did NOT have these skills, I hit roadblocks like the OP but figured things out from reading and learning and asking questions on this website. You might find someone to assist you locally but it is much better to learn and be self sufficient. Two or three hours spent reading would make a world of difference in tackling your issue.
