Cloud-based systems and methods to securely share electronic files use a cloud or virtualized server to handle management tasks related to file sharing, while file storage is maintained securely by servers that are not part of the cloud. The content of the file to be shared is not transmitted to or by the cloud. Share requests from file senders, notifications to target recipients, and retrieve requests from target recipients are transmitted to and/or by the cloud.

Systems and methods for secure cloud-based media file sharing

Tracking a target across a region is disclosed. A graphical user interface is provided that displays, in a first region, video from a field of view of a main video device, and, in a plurality of second regions, video from a field of view of each of a plurality of perimeter video devices (PVDs). The field of view of each PVD is proximate to the main video device's field of view. A selection of one of the plurality of PVDs is received. In response, video from a field of view of the selected PVD is displayed in the first region, and a plurality of candidate PVDs is identified. Each candidate PVD has a field of view proximate to the field of view of the selected PVD. The plurality of second regions is then repopulated with video from a field of view of each of the plurality of identified candidate PVDs.

Tracking people and objects using multiple live and recorded surveillance camera video feeds

Effecting the transmission of video data across a network of resources that includes incompatible resources is disclosed. Information indicating a source device and a destination device is received. The source device originates the video data and the destination device is to receive the video data. A plurality of paths between the source device and the destination device is identified. Each path is defined by a set of resources, the set of resources including resources needed to transmit the video data across any incompatible resources in the path. From the plurality of paths, a best path for transmission of the video data is determined based on the set of resources for that path, a distance between the source device and the destination device along that path, and a quality of the video data maintained by that path. The transmission of the video data is then effected across the determined best path.

Optimal routing of audio, video, and control data through heterogeneous networks

A content delivery network has a content switch that intercepts content requests transmitted toward the origin server. The content switch distinguishes the content request as originating either external to the content delivery network or from within the content delivery network. The content switch forwards external requests to a content router, within the content delivery network and forwards internal requests to the origin server. Devices external to the content delivery network do not access the content carried by the origin server directly and, therefore, the content delivery network does not require the origin server alter its content when storing the content on a content server within the content delivery network. Use of the content switch, therefore, minimizes or eliminates the time, effort, and expense of rewriting content cached from the origin server to the content server within the content delivery network.
