Under what circumstances can smart locks take photos and send text messages?

Someone stops at the door, someone rings the doorbell or opens the door, and you will know by querying the intelligent visual doorbell.

1. The function of the intelligent door lock is not limited to opening and closing the door lock. When someone stops at the door, it will automatically capture photos and send them to the owner or family.

2. When someone rings the doorbell or opens the door, the system will automatically push information to the user to remind the user what happened outside the door.
