Cameras are generally acceptable in hallways, parking lots, front offices where students, employees, and parents come and go, gymnasiums, cafeterias, supply rooms and classrooms. The installation of cameras in classrooms may be objected to by some teachers. There were an estimated 30 million surveillance cameras in the United States in 2011. Video surveillance has been common in the United States since the 1990s; for example, one manufacturer reported net earnings of $120 million in 1995.

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, one or more of the streams are sent from the video source 222 directly to a client device 220 e. g.
