    摘要： This document describes techniques, apparatuses, and systems for batch size adjustment using latency-critical event recognition. The techniques described herein enable an electronic device (e.g., security camera) to determine the likelihood of an event of interest (e.g., latency-critical event) occurring in data (e.g., audio and/or video) captured by the electronic device. To make such a determination, the electronic device may switch upload modes to upload the data, using a different batch size to reduce latency, to another device for user access, based on the likelihood of an event of interest occurring in the data. In this way, the techniques, apparatuses, and systems for batch size adjustment using latency-critical event recognition provide an efficient way to provide all-day security monitoring.

    摘要： Technology permitting secure storage and transmission of data stream as well as tiered access to multiple data stream according to permission. Data streams may be encrypted using symmetric encryption performed with varying symmetric keys according to a key stream of symmetric keys. Native data may be discarded for safety. Whole or partial key streams may be encrypted using the public keys of authorized entities having permission to access respective data streams or portions thereof. Only the corresponding private keys can decrypt the encrypted key streams required to decrypt the encrypted data streams. Thus rigorous access control is provided. IT personnel accessing data stream files on a server or intruders maliciously obtaining files will not be able to derive the data stream. Sensitive data streams may be stored using cloud services despite inherent risks.

    摘要： A system provides a transformed video stream from, a publicly or privately owned and operated camera bearing on an in-scope location vicinity, to, a responding emergency service agency (ESA). A request from an emergency services agent's display terminal includes location indicia and elicits a map of cameras bearing on the location vicinity as well as other display terminals in the area. Upon request, an application programming interface enables a video stream to comply with the privacy and access settings of the camera owner/operators. A plurality of private and public security surveillance cameras is coupled to a server. Exterior/street view video images are streamed to the server which may contact an owner for emergency access. An emergency agency vehicle at a location has a display for a selected gallery of obfuscated exterior/street views from cooperative networks of public and private security cameras bearing on the vicinity of an incident.

    摘要： Streaming and storing content captured by audio/video (A/V) recording and communication devices in accordance with various embodiments of the present disclosure are provided. In one embodiment, a method for transmitting and storing video images captured by an A/V recording and communication device including a camera and memory is provided, the method comprising: capturing video images of a field of view of the camera; detecting a person at the A/V recording and communication device; in response to detecting the person, storing a high-quality version of the video images at the memory of the A/V recording and communication device; determining an available network bit rate for video streaming; if the available network bit rate is above a threshold, then transmitting a high-quality video stream to a client device; and if the available network bit rate is below the threshold, then transmitting a low-quality video stream to the client device.
