Abstract: Systems and methods described herein involve establishing a secure hypertext transfer protocol (HTTPS) connection between a media server and one or more cameras selected by a client device through a web browser application; establishing a websocket secure (WSS) connection between the media server and the web browser application of the client device; receiving, at the media server, media chunks of live video from the selected one or more cameras through the HTTPS connection; and transmitting, from the media server, the media chunks of live video received from the selected one or more cameras to the web browser application of the client device through the WSS connection.

Abstract: To adjust an aspect ratio of an image to match the aspect ratio of a display area for presenting the image, a computing device receives an image having a first aspect ratio, and obtains a second aspect ratio for a display area of a display in which to present the image, where the second aspect ratio is different from the first aspect ratio. The computing device extends the image to include one or more additional features which were not included in the image. Additionally, the computing device automatically crops the extended image around an identified region of interest by selecting a portion of the extended image that has an aspect ratio which matches the second aspect ratio of the display area, and provides the cropped image for presentation within the display area of the display.

Abstract: A foldable storage box has four hard side surfaces in a vertical direction, a soft bottom surface, and a hard support plate that matches the bottom surface and is disposed on the bottom surface. Each of the side surfaces has a non-woven fabric interlayer, and a hard plug board is inserted in the interlayer. At least one pair of the four side surfaces are capable of being folded along a vertical folding axis. Vertical flexible dividing lines are disposed at intersections of the four side surfaces and the vertical folding axis, and the flexible dividing lines confine and isolate the respective hard plug boards in a horizontal direction. The flexible dividing lines are formed by welding two layers of non-woven fabrics in an ultrasonic welding manner.
