1. A computer-implemented method comprising:
determining a likely identity of a visitor who arrived at a property that is associated with two or more people, wherein determining the likely identity of the visitor who arrived at the property that is associated with the two or more people comprises:
detecting an object within a threshold distance of the visitor who arrived at the property;
determining, using object recognition, that the object is a specific object that has a frequency of being detected within the threshold distance of a particular visitor, which frequency satisfies a frequency threshold; and
in response to determining that the object is the specific object that has the frequency that satisfies the frequency threshold, determining that the visitor is likely the particular visitor;
selecting, from the two or more people, a target person using the likely identity of the visitor; and
sending, to a device of the target person, a notification that indicates that the visitor arrived at the property.
