Guidance ref. modes and automation

Hope someone will take the time to guide me:-)
I have 3 Cam 2 Pro and would like to set these cameras up correctly.

Camera 1, 2 and 3 must be using geofencing mode. Thats simple, and dont need help with that.

Camera 1 must be active 24/7 no matter I am home or not.

Camera 2 and 3 must be active when I am home from sunset to sunrise.

How do I combine these three scenarios?

Thank you very much for helping out!

You create different security modes, then you create a schedules security mode that sets which mode is active and when.
