This setting will make the sensor ACTIVE only when you arm the system by pressing 'Away' on the app or 'Arm' on the display panel when you leave the house.
The sensor will NOT be active when you arm the system by pressing 'Home' on the app or 'Stay Arm' on the display panel . For example, this allows you to walk freely in the middle of the night to get a glass of water without triggering the motion.
