Abstract: Methods, systems, and techniques for handling of event notifications in non-standard formats. An event notification sent from an event notification sending device of a video surveillance system is received at an event notification handling device of the system. The event notification is in a format not natively supported by at least one device of the system. The event notification is translated into a format supported by the at least one device, with the supported format being defined in a list of non-standard formats. A rule associated with the event notification is applied to perform an action. Prior to receiving the event notification, an initialization method may be performed in which the event notification handling device subscribes to receive the event notification.

Abstract: There is provided an appearance search system comprising one or more cameras configured to capture video of a scene, the video having images of objects. The system comprises one or more processors and memory comprising computer program code stored on the memory and configured when executed by the one or more processors to cause the one or more processors to perform a method. The method comprises identifying one or more of the objects within the images of the objects. The method further comprises implementing a learning machine configured to generate signatures of the identified objects and generate a signature of an object of interest. The system further comprises a network configured to send the images of the objects from the camera to the one or more processors.

Abstract: A computer implemented method for managing data received from a video source device is disclosed. At least a first storage tier and a second storage tier on a storage medium are identified for respectively storing different categories of data. As data streams are received from the video source, the data streams are associated with at least the first storage tier or the second storage tier and data from the received streams are stored in the associated storage tier. When the storage medium is full or meets some other specified maximum capacity threshold, data is deleted beginning with data that has an age that exceeds one or more specified maximum retention times, followed by data with the oldest age from one or both of the first and second storage tiers.

Abstract: A physical security system is described comprising a simplified method for selection of a compute node from a cluster of compute nodes with which to assign a role or acquire a service. The method determines a scalar priority value for compute nodes in the cluster, and allows selection of a compute node by simply choosing the highest priority scalar value. Scalar priority values may be determined by one or more of: a compute node license type, capacity limits, a hardware capability, a software capability, and a current node load.

Abstract: A physical security system may define sites associated with cameras. Sites may be added as a child site off of a parent site to form a site family. Once set up, ranked user and group privileges on the parent site may be pushed to the child sites, and controlled by the parent site. The child sites may still define local users and groups so that the child site may operate if there is a loss of connectivity to the parent site.

Abstract: A system for streaming multiple encodings of a source video stream is disclosed. A source video device system captures and/or receives source video comprising a plurality of source video frames. The source video device system encodes the source video frames into virtual frames, with each of the virtual frames being encoded using at least one different encoding parameter. The source video device system forms a container frame from the virtual frames and transmits the container frame over a network. In an example embodiment, the container frame comprises the virtual frames associated with a particular source frame and a container timestamp applicable to all of the virtual frames in the container frame.

Abstract: A system for streaming multiple encodings of a source video stream is disclosed. A source video device system captures and/or receives source video comprising a plurality of source video frames. The source video device system encodes the source video frames into virtual frames, with each of the virtual frames being encoded using at least one different encoding parameter. To each virtual frame is appended virtual stream identifier which is appropriate for a selected transmission mechanism. The source video device system forms a container frame from the virtual frames and transmits the container frame over a network. Devices receiving transmissions over unreliable connections may reconstruct the transmitted streams using the synchronization headers.
