Remote access to second camera

I currently monitor 2 cameras at my home address and one remotely from a second property - the single camera was dead easy to set up with ss as all I had to do was input the ip address of the second property and ss at the first found it etc.

i now need to add a second camera but im wondering how it will get set up as if I enter the main up address surely it will just see the original camera?

as I am not going to be able to check if ss sees it until i am back home is there any way of making sure ss will be able to find the second camera? I don’t really want to travel home to find it doesn’t work!
