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, one or more of the streams are sent from the video source 222 directly to a client device 220 e. g. , without being routed to, or processed by, the server system 164. In some implementations, one or more of the streams is stored at the camera 118 or 106 e. g. , in memory 406, FIG. 4 and/or a local storage device e. g. , a dedicated recording device, such as a digital video recorder DVR.

In some implementations, the video data may be stored at a local storage device of the video source 501 by default, and only video portions corresponding to motion event candidates detected in the video stream are uploaded to the server system 164 e. g. , in real time. 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. As shown in FIG. 5, the video source 501 includes a camera 118 or 106, and an optional controller device.
