With Arlo Smart, your camera still records videos to your library when other motion is detected, but you receive fewer unwanted notifications.
To enable the Person Detection feature:
Launch the Arlo app or log in to your Arlo account at my.arlo.com.
Tap or click Settings.
Under Arlo Smart, tap or click Smart Notifications.
Select a camera for which you want to receive Arlo Smart notifications.
Tap or click the slider next to People to enable Arlo Smart Person Detection notifications. Note: To get notifications only when people are detected, you must disable the Vehicles, Animal, and All Other Motion sliders.
