What is the difference between "Arm Mode" and "Disarm Mode"

[CoastalJack]

What is the difference between "Arm Mode" and "Disarm Mode" in Defense Settings on the phone.
I understand "Arm Mode" I think, but why is there a Motion Detection, and Alert Sensitivity setting in "Disarm Mode" ?

 

[Jackie]

Arm/disarm mode allow users to manually activate and deactivate motion detection, or alarm detection by other wireless security sensors (if your camera can support wireless security sensors.)

it works like a burglar alarm system.

When the system is armed in this mode, all sensors are active and the any of the sensors is triggered, the system will activate the alarm as well as the auto-dialer function.
Home arm mode: When the system is armed in this mode, all PIR sensor zones are excluded from the system and the activation of this sensor will not activate the alarm either the auto dialer function.
