Examples of a virtualized file server that persistently stores file system event data records are described. The virtualized file server may include an audit framework with a connector publisher that is configured to publish the event data records and other information for consumption by other services using a message system. The event data records may include data related to various operations on the file system executed by the VFS. The VFS may persistently store event data records according to a data retention policy and/or until an event data record is consumed by one or more particular services.

Virtualized file servers and methods to persistently store file system event data

The various embodiments described herein include a method performed at a camera device. The method includes: encoding a first stream of images from the camera device with a first bitrate; transmitting the encoded first stream of images to a server system; determining, at the camera device, one or more transmission metrics for the transmitted first stream of images; based on the one or more transmission metrics, encoding a second stream of images from the camera device with a second bitrate distinct from the first bitrate; and transmitting the encoded second stream of images to the server system.

Methods and devices for dynamic adaptation of encoding bitrate for video streaming

A method, in an application executing at a client device, includes: receiving a plurality of video feeds, each video feed of the plurality of video feeds corresponding to a respective remote camera of a plurality of remote cameras, where the video feeds are received concurrently by the device from a server system communicatively coupled to the remote cameras; displaying a first user interface, the first user interface including a plurality of user interface objects, each user interface object of the plurality of user interface objects being associated with a respective remote camera of the remote cameras; and displaying in each user interface object of the plurality of user interface objects the video feed corresponding to the respective remote camera with which the user interface object is associated, where at least one of the video feeds is displayed with cropping.

Methods and systems for presenting multiple live video feeds in a user interface

The various embodiments described herein include a method performed at a camera device. The method includes: (i) capturing a stream of images using the image sensor; and, (ii) while capturing the stream of images: (a) encoding a first portion of the stream of images with a first bitrate; (b) transmitting the encoded first portion of the stream of images to a server system; (c) obtaining one or more transmission metrics for the transmitted first portion of the stream of images; (d) based on the one or more transmission metrics, encoding a second portion of the stream of images with a second bitrate, distinct from the first bitrate; and (e) transmitting the encoded second portion of the stream of images to the server system.

Aspects of the disclosure provide a regulator circuit including an output circuit, an error detection circuit and an intermediate circuit. The output circuit is configured to receive a first supply voltage, output and regulate a second supply voltage based on a control signal. The error detection circuit is responsive to the first supply voltage, and is configured to compare the second supply voltage with a reference voltage, and generate an error signal with a voltage level that is indicative of a difference between the second supply voltage and the reference voltage. The intermediate circuit is configured to generate a first electrical current based on the error signal and a second electrical current based on the second supply voltage, combine the first electrical current and the second electrical current to generate a third electrical current, and generate the control signal at least partially based on the third electrical current.

Voltage regulator

Aspects of the disclosure provide a circuit for providing a power supply. The circuit includes a control signal generator circuit and a switch network circuit. The control signal generator circuit is configured to generate a control signal with a voltage level that is a function of an output voltage on a load capacitor. The switch network circuit is coupled with the load capacitor and a flying capacitor to form a charge pump circuit. The switch network circuit is configured to charge the flying capacitor in a charge stage and pump the flying capacitor in a pump stage to generate the output voltage on the load capacitor. The switch network circuit is configured to provide a pump control voltage to the flying capacitor during the pump stage. The pump control voltage has a voltage level that is adjusted based on the control signal to maintain the output voltage to be stable.
