Abstract: A device (e.g., a security device, a video doorbell, a security camera, etc.) may receive an input voltage and based on the input voltage may determine the input power available to the device. The device may access various power level requirements associated with one or more functional components associated with the device. The device may then determine one or more functional components to activate or set to an active status on the device based on the input power available to the device, component power level requirements for one or more of the functional components, and other factors such as priority levels and preferences.

Abstract: Systems, apparatuses, and methods are described for managing temperature of a rechargeable battery between multiple available states of heating. Different thresholds may be used for turning on, and turning off, one or more heating elements associated with the rechargeable battery, and/or for otherwise changing states of the one or more heating elements.

Abstract: Systems, apparatuses, and methods are described for using one or more components of a device, such as a camera, to generate complementary heat for the device, such as a camera lens of the device. In one aspect this can be accomplished by activating the one or more components and/or by causing the one or more components to operate in a particular manner expected to generate heat. The generated heat may be instead of or in addition to heat generated by one or more dedicated heaters. The selected components may produce heat as an incidental effect for performing other functions of the device.

Abstract: Systems, methods, and apparatuses are described for detecting synchronization errors between audio and video signals. Scene changes may be detected based on anchor frames. Offsets between a scene change in a video signal and a reduced audio level or burst of high audio level in the audio signal may indicate a synchronization error.

Abstract: Systems, methods, and apparatuses for power management of doorbell systems are described herein. A doorbell system comprising at least a camera and a chime may cause a connection to be established. The connection may be established between the camera at least one user device. A first indication to cause the chime to output a first audio notification may be received. Based on determining that the connection is established between the camera and the at least one user device, prevention of outputting the first audio notification by the chime may be caused.

Abstract: A voice controlled device may be blocked from accessing a network. Another computing device may receive audio data comprising a voice command associated with controlling the voice controlled device. If a trigger condition for unblocking network access is detected, the computing device may send data to a network device to cause the network device to unblock network access. The network access may be blocked again if a triggering condition for blocking network access is satisfied.

Abstract: A communications access point may provide access to a wireless communications network to a user device located at a first location. The communications access point may determine that the user device is moving from the first location to a second location where access to the wireless network is limited or not available. In response to the determination, the communications access point may provide access to the wireless network at the second location by extending a coverage area of the wireless network.

Abstract: A system for storing and moving data based on the location of a user or a change in location of a user is described herein. Data associated with a user may be stored at one or more storage devices associated with a location of the user. Some or all of the data associated with the user may be moved to one or more other storage devices if, for example, the user moves to a different location or is expected to move to a different location, so that the user's data may be more efficiently accessed by the user.
