1. A method comprising:
obtaining a notification i) of a delivery of a package at a property ii) that includes a first image depicting the package;
comparing the first image from the notification depicting the package to a model of a scene that represents an area of the property;
determining whether the first image satisfies similarity criteria for matching the model of the scene using a result of the comparison;
in response to determining that the first image satisfies the similarity criteria for matching the model of the scene, determining that the first image likely depicts the same area of the property as the area of the property represented by the scene;
in response to determining that the first image likely depicts the same area of the property as the area of the property represented by the scene, determining that the package has been delivered to the property;
generating a package model that represents an appearance of the package, including:
identifying a group of pixels in the first image that do not match the model of the scene; and
classifying, within the group of pixels, a subset of pixels as corresponding to the package, including determining that the subset of pixels does not lie in a ground plane of the first image; and
tracking, using the package model, a location of the package for use in determining whether to provide an alert to a device about the location of the package.
