+1^^^.
You would also want to create a user, make them non-admin, set up username and password.
You can then assign a specific camera to a group and limit their viewing to only that group (needed if you have more than 1 camera on BI).
You can limit their bandwidth, login time, schedule their access time, allow PTZ functions, if they can see recorded clips or not and more.
All of this is covered in BI's built-in 'Help"...search for "users".
