This disclosure describes, in part, an audio/video (A/V) device that includes a first camera for generating first image data and one or more second cameras for both motion detection and generating second image data. For instance, the A/V device may generate and then store the second image data in one or more buffers. The A/V device may then detect an event, such as possible motion of an object. Based on detecting the event, A/V device may cause the one or more second cameras to cease generating the second image data and cause the first camera to begin generating the first image data. The A/V device may then process the second image data and send the processed second image data to a computing system. Next, the A/V device may process the first image data and send the processed first image data to the computing system.

Audio/video electronic device

This disclosure describes, in part, techniques for selecting encoding parameters for an electronic device. For instance, remote system(s) may receive, from the electronic device, video data representing a video. The remote system(s) may then analyze the video data to identify portions of the video that represented different areas located within the field of view (FOV) of the electronic device. The areas may include static areas, which do not include recurring motion, and/or dynamic areas, which include recurring motion. Additionally, the remote system(s) may analyze the video data to select encoding parameters for encoding the video data and/or for encoding the portions of the video data that represent the identified areas. The electronic device may then receive the encoding parameters from the remote system(s) and use the encoding parameters to encode additional video data that is generated by the electronic device.

Techniques for encoding video data

Streaming and storing video for 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 an A/V recording and communication device comprises: recording video image data; executing a write operation to write the video image data at a write rate; executing a read operation to read the video image data at a first read rate that is greater than the write rate; continuing to read the video image data at the first read rate until the read operation catches up to the write operation; reading the video image data at a second read rate equal to the write rate; and transmitting streaming video to a client device, wherein a beginning portion of the streaming video is streamed at a first stream rate and thereafter streaming at a second stream rate less than the first stream rate.

Streaming and storing video for audio/video recording and communication devices

The present embodiments solve the problem of low-quality stored footage from video stream by storing copies of data packets at a local storage device of the A/V recording and communication device. The locally stored data is subsequently (e.g., after the live stream has terminated) uploaded to a remote storage device. If any data packets are lost during the upload process, those lost data packets can be re-sent from the local storage device to the remote storage device so that the complete recording can be stored at the remote storage device. The subsequent upload process may, in some embodiments, comprise a reliable data transfer protocol.

Streaming and storing video content captured by an audio/video recording and communication device

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.
