Patent number: 11521325Abstract: A method, system and apparatus for image capture, analysis and transmission are provided. A link aggregation method involves identifying controller network ports to a source connected to the same subnetwork; producing packets associating corresponding controller network ports selected by the source CPU for substantially uniform selection; and transmitting the packets to their corresponding network ports. An image analysis method involves producing by a camera an indication whether a region of an image differs by a threshold extent from a corresponding region of a reference image; transmitting the indication and image data to a controller via a communications network; and storing at the controller the image data and the indication in association therewith. The controller may perform operations according to positive indications.Type: GrantFiled: July 26, 2021Date of Patent: December 6, 2022Assignee: MOTOROLA SOLUTIONS, INCInventors: Andrew Martz, Ross Wightman, Shaun P.

Patent number: 11228764Abstract: 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.Type: GrantFiled: December 11, 2014Date of Patent: January 18, 2022Assignee: AVIGILON CORPORATIONInventors: Shaun P.

Patent number: 11200148Abstract: Methods, systems, and techniques for tracing callstacks, the results of which can be used to identify a source of a memory leak. A memory heap is sampled at different times to determine counts of respective allocations of different allocations at the different times. From the counts of the respective allocations at the different times, rates at which the respective allocations have changed over the different times, and which of the rates is equal to or greater than a leak indication rate, are determined. Callstacks for respective allocations of the different allocation sizes for each of the rates that is equal to or greater than the leak indication rate are traced. The results of the tracing may be used during debugging to identify the source of the memory leak.Type: GrantFiled: April 7, 2020Date of Patent: December 14, 2021Assignee: AVIGILON CORPORATIONInventors: Daniel James Booth, Shaun P.

Patent number: 11197057Abstract: 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.Type: GrantFiled: October 12, 2016Date of Patent: December 7, 2021Assignee: AVIGILON CORPORATIONInventors: Shaun P.

Patent number: 10785339Abstract: 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.

Patent number: 10547693Abstract: 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.Type: GrantFiled: March 31, 2016Date of Patent: January 28, 2020Assignee: AVIGILON CORPORATIONInventors: Shaun P.

Publication number: 20200014740Abstract: Tile stream selection for mobile bandwidth optimization is disclosed. Also disclosed is a method that includes storing a plurality of video tiles combinable to form a larger portion or all of a high resolution video. The method also includes processing a request to stream at least a first video tile of the video tiles. The processing includes determining a size of a first portion of a region of interest falling within the first video tile; determining whether the size of the first portion is below a threshold size; and transmitting, over at least one network, a first video stream that includes the first video tile. The first video tile is transmitted in: a first resolution when the size of the first portion is below the threshold size; and a second resolution when the size of the first portion is above the threshold size.Type: ApplicationFiled: July 6, 2018Publication date: January 9, 2020Applicant: Avigilon CorporationInventors: Jimmy Hsin-Chia Chao, Brummell Paul L.
