Urgent Help - Motion Detection Grid - Hikvision Doorbell

Hi Fellow Hikvision Users.

Please help me.. I am trying to configure motion detection grid for my Hikvision video Doorbell..

Could you kindly advise in the attached image which area will trigger a notification?

Will it be Area 1 (Red Grid) or Area 2 (Clear No Grid) I’m confused to workout which option actually means that a notification will be triggered.

I have provided attached image, and struggling to workout which setting actually triggers a event/notification?
