View at AmazonCheck Walmart?Best nighttime video quality in our testsVery affordableSmart home compatibilityAverage daytime video qualityPoor audio qualityNo scheduled recording optionsThe Belkin NetCam HD+ is one of the most affordable security cameras we tested, selling for around $75 on Amazon at the time of this writing. The price makes it an excellent value, especially considering it earned the highest nighttime video score in our tests with excellent range and clarity in total darkness. In daytime testing, the NetCam had average video quality in bright and low light situations, and while its 720p video resolution doesn't hold up to the 1080p cameras in our review, it’s sufficient for most people. Unfortunately, the Belkin NetCam HD+ had the lowest audio quality in our tests; it was unintelligible. However, audio is arguably less important than video for the purposes of an inexpensive security camera.

Although many
aspects of the present technology are described from the perspective of the server system 164, the corresponding actions performed by a client device 220 and/or the video sources 222 would be apparent to one of skill in the art. Similarly, some aspects of the present technology may be described from the perspective of a client device or a video source, and the corresponding actions performed by the video server would be apparent to one of skill in the art. Furthermore, some aspects of the present technology may be performed by the server system 164, a client device 220, and a video source 222 cooperatively. In some implementations, a video source 222 e. g. , a camera 118 or 106 transmits one or more streams of video data to the server system 164. In some implementations, the one or more streams may
include multiple streams, of respective resolutions and/or frame rates, of the raw video captured by the camera 118 or 106. In some implementations, the multiple streams may include a “primary” stream with a certain resolution and frame rate, corresponding to the raw video captured by the camera 118 or 106, and one or more additional streams. An additional stream may be the same video stream as the “primary” stream but at a different resolution and/or frame rate, or a stream that captures a portion of the “primary” stream e. g. , cropped to include a portion of the field of view or pixels of the primary stream at the same or different resolution and/or frame rate as the “primary” stream.

In some implementations, the video source 501 dynamically determines at what display resolution the video stream is to be uploaded to the server system 164. In some implementations, the video source 501 dynamically determines which parts of the video stream are to be uploaded to the server system 164. For example, in some implementations, depending on the current server load and network conditions, the video source 501 optionally prioritizes the uploading of video portions
corresponding to newly detected motion event candidates ahead of other portions of the video stream that do not contain any motion event candidates; or the video source 501 uploads the video portions corresponding to newly detected motion event candidates at higher display resolutions than the other portions of the video stream. This upload prioritization helps to ensure that important motion events are detected and alerted to the reviewer in real time, even when the network conditions and server load are less than optimal. In some implementations, the video source 501 implements two parallel upload connections, one for uploading the continuous video stream captured by the
camera 118 or 106, and the other for uploading video portions corresponding to detected motion event candidates. At any given time, the video source 501 determines whether the uploading of the continuous video stream needs to be suspended temporarily to ensure that sufficient bandwidth is given to the uploading of the video segments corresponding to newly detected motion event candidates.
