Abstract: Techniques are described for using information from a knob sensor of an appliance in a property monitoring system. In some implementations, a monitoring system may be configured to receive sensor information from a knob, receive monitoring device information from a monitoring device and, based on the sensor information from the knob, identify a knob event. The monitoring system may integrate the knob event with the monitoring device information and analyze the integrated knob event and monitoring device information against one or more rules related to usage of the appliance in view of the state of the property. Based on analyzing the integrated knob event and monitoring device information, the monitoring system may determine whether to perform an action, such as notifying a user or activating an appliance.

Abstract: Systems and techniques are described for supervising and monitoring the delivery of a package to a property. In some implementations, shipment data indicating a package to be delivered at the property and identification information for a first person is obtained. A request for a second person to access the property and deliver the package that includes identification information for the second person is received. Identification information for the first person is compared to the identification information for the second person. Access to the property is provided to the second person. Sensor data generated by one or more sensors that are located throughout the property and while providing access to the property is obtained and analyzed. A determination of whether the second person delivered the package to the property is made based on analyzing the sensor data. Data indicating the determination is provided for output.

Abstract: Systems and techniques are described for pet monitoring during unattended delivery. In some implementations, a monitoring system monitors a property includes sensors located throughout the property and generates sensor data. A monitor control unit receives a first indication that a resident of the property will be receiving a delivery during a delivery time. Based on the sensor data and during the delivery time, the monitor control unit determines that a pet, that resides at the property, has been restrained. The monitor control unit provides, to a delivery person, a second indication that the pet at the property has been restrained.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for group identification and monitoring. The methods, systems, and apparatus include actions of determining, using one or more first frames of a video sequence, that two people each of whom is depicted in at least one of the first frames satisfy a grouping criteria that indicates that the two people should be grouped for video analysis, determining, using one or more second frames of the video sequence at least some of which were captured after the one or more first frames and which depict at least one of the two people, that the two people satisfy a degrouping criteria that indicates that the two people should not be grouped for video analysis, determining that a physical distance between the two people violates a distance criteria, and providing an alert that the distance criteria is violated.

Abstract: A computer-implemented method includes obtaining a delivery schedule for a property, determining that a portable camera used by a visitor is at the property, determining that the portable camera corresponds to the delivery schedule, in response to determining that the portable camera corresponds to the delivery schedule, providing access to the property, and obtaining a video recorded by the portable camera.
