the first part is a hud element with a touch to toggle behavior, when on the indicator is green and crossing a camsys marker will make the camaera change automatically, if you toggle it off the light goes green and just blink green briefly when you cross a marker (also if you decide to toggle it on, it will give you the last recorded camera setting)

now for the developper part: this is the code you will put in invisible prims palced like tripwires in your building, they detect the direction the avatar go so you can set up 2 camera behavior depending if they "enter the room" or "leave the room"

you are free to reuse this code and modify it as long as the compatibility with the original system isn't compromised.
