    Abstract: Disclosed are methods, systems, and apparatus for monitoring delivered packages using video. A method includes obtaining a notification of a delivery of a package at a property that includes a first image depicting the package; obtaining a second image captured by a camera at the property; determining, using the first image and the second image, that the package has been delivered to the property; generating a package model that represents an appearance of the package; and tracking a location of the package for use in determining whether to provide an alert to a device about the location of the package. Determining that the package has been delivered to the property comprises: comparing the first image to a model of a scene of the property; determining that the first image satisfies similarity criteria for matching the model of the scene; and determining that the second image likely depicts the package.

    Abstract: A monitoring system that is configured to monitor a property is disclosed. The monitoring system includes a passive infrared (PIR) sensor configured to generate reference PIR data that represents motion within an area of the property; an auxiliary sensor configured to generate auxiliary sensor data that represents an attribute of the area of the property; and a motion sensor device. The motion sensor device is configured to: obtain the reference PIR data; determine that a first set of motion detection criteria is satisfied by the reference PIR data; in response to determining that the first set of motion detection criteria is satisfied by the reference PIR data, obtain the auxiliary sensor data; obtain a second set of motion detection criteria based on the reference PIR data and the auxiliary sensor data; and determine whether the second set of motion detection criteria is satisfied by additional PIR data.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for machine learning for home understanding and notification. In one aspect, a method includes obtaining reference videos from a camera within a premises of a home, determining, from the reference videos, timing of actions in a routine that a particular person performs before leaving the home, determining from a sample video from the camera within the home that the particular person appears to be out of sync in performing a particular action based on the timing of actions in the routine determined from the reference videos, and in response, providing a notification to the particular person.

    Abstract: Methods, systems, and apparatus for video analytics evaluation are disclosed. A method includes: identifying a video to display a result of an evaluation of video analysis; identifying a particular time in the video when a video analysis determination does not match a ground truth determination for the video; displaying an image from the particular time in the video; and displaying an indication that the video analysis determination does not match the ground truth determination for the video. Displaying the image from the particular time in the video can include generating a graphical user interface for presentation on a display of a computing device. The indication that the video analysis determination does not match the ground truth determination for the video can include a user-selectable icon. In response to a user selecting the user-selectable icon, the method can include displaying video analysis results for the particular time in the video.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for virtual inductance loop technology. In one aspect, a method includes calibrating, using calibration parameters, cameras directed towards a scene, obtaining, by the cameras, images corresponding to the scene, identifying reference structures in the scene, and determining, based on the reference structures and the images, locations in the scene for generating virtual inductance loop lines in the scene. The method also includes generating the virtual inductance loop lines to be imposed on the images, comparing the virtual inductance loop lines to determine one or more offsets, and determining, based on the offsets, characteristics of the scene.
