two cameras, limited viewing?

[Conrad0011]

We already have 1 1080 Wifi ProHD camera. Works great. It is set up so that our son and his wife can log in and watch our granddaughter while she is here, in the playroom.
Here's my question. If we get another camera and want it set up in the living room, for security purposes, will my son and his wife also have access to view it? We'd rather keep that one to ourselves but be able to view it through the app . But want to limit son and his wife to the playroom. Is that doable???

Thanks

They are totally separate. Just don't give him the camera info.
