Getting the settings in a 'mode' on a security camera to work when switching modes

HI
I have two floodlight cams, wireless door bell and 3 indoor cams. Before I go to bed I switch on the cameras and alerts. I tried to create a new ‘mode’, called Overnight, but all it did was switch the cameras to motion detection when I was trying to create it. What should I do and is there a simple guide to follow to set up a new mode and make it a one tap change (per device) at bed time?
