Abstract: Techniques are described for detecting and handling unauthenticated commands in a property monitoring system. In some implementations, a monitoring system may include sensors located throughout a property, a monitoring control unit, and an input device. The monitoring control unit may be configured to receive data collected by the sensors, as well as an input command detected by the input device. For an input command that does not include authentication information, the monitoring control unit may generate property state information based on the sensor data, then analyze the property state data and the input command against one or more rules that relate to authorization of unauthenticated commands. Based on the analysis, the monitoring control unit may determine whether to perform the action corresponding to the input command or whether to perform another action, for example, generating and providing a notification or authorization request to a user.

Abstract: A circuit is described for powering a chime that outputs audio in response to detection of an entity by a video doorbell. The circuit includes a power source for generating a first signal. A first switch is coupled to the power source. The first switch is configured to provide, in response to the first signal, a first direct-current (DC) voltage signal during a first operating mode where the video doorbell receives an input that triggers actuation of the chime in response to detection of the entity. A second switch is coupled to the power source and the first switch. The second switch is configured to provide, in response to the first signal, a second DC voltage signal during a second operating mode where the chime outputs the audio in response to the input that triggers actuation of the chime in response to detection of the entity.
