Abstract: A physical security system that includes multiple server nodes may be upgraded by receiving an upgrade installation package from a client and propagating the installation package between at least two of the server nodes. One of the server nodes (“source server”) receives the installation package from the client and another of the server nodes (“requesting server”) requests and receives the installation package from the source server. To transfer the installation package from the source to the requesting server, the source server notifies the requesting server that the installation package is present at the source server, the requesting server then sends the source server a request for the installation package, and the source server then sends the installation package to the requesting server in response to the request. The requesting server may then be upgraded by running the installation package.

Abstract: A method of detecting unusual motion is provided, including: determining features occurring during a fixed time period; grouping the features into first and second subsets of the fixed time period; grouping the features in each of the first and second subsets into at least one pattern interval; and determining when an unusual event has occurred using at least one of the pattern intervals.

Abstract: A camera device includes a camera module that captures a scene corresponding to a field of view of the camera module. A wireless power transmitter of the camera devices transmits wireless power to a battery-powered external sensing device. A transceiver is further operable for receiving from the external sensing device sensed data. A network module transmits the image and sensed data to an external networked device. A power supply receives power over a wired connection and supplies power to the camera module, transceiver, networking module and wireless transmitter. The external sensing device may be an access control device that includes a sensor for sensing the presence of a machine readable toke and reading an identifier of the physical token. The access control device further includes a lock controller for selectively locking and unlocking a physical lock.

Abstract: Compensating for delay in a Pan-Tilt-Zoom (PTZ) camera system is disclosed. Client-side view transformation is carried out to emulate a future Field Of View (FOV) of the camera so that the impact of latency is reduced.

Abstract: A camera that supports removable storage divided into multiple partitions is configured to write files to removable storage that is formatted into journaled and non-journaled partitions. The journaled partition uses a journaling file system and the non-journaled partition uses a non-journaling file system that is supported natively by an operating system, such as the operating system of a desktop computer. The non-journaled partition has stored on it computer program code executable by a processor to use the operating system to access files stored on the journaled partition. The camera may also be configured to partition the removable storage into the journaled and non-journaled partitions. The camera writes data to the journaled partition. This permits the processor to access the files stored on the journaled partition by the camera even if the operating system does not natively support the journaled partition.

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: Methods, systems, and techniques for sharing layers between convolutional neural networks (CNNs). A data processing system may include a first and a second CNN that share a first group of layers. The first CNN may include the first group of layers in series with a second group of layers and be configured such that data for the first CNN is input to the first group of layers. The second CNN may include the first group of layers in series with a third group of layers and be configured such that data for the second CNN is also input to the first group of layers.

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: Methods, systems, and techniques for adjusting camera focus to facilitate infrared imaging are employed to account for a difference in wavelength between visible and infrared light to permit sharp imaging regardless of whether imaging is performed using visible or infrared light. Camera focus is adjusted in accordance with base and offset values. The base value may be determined in accordance with a curve relating focus motor position and object distance and the offset value may be manually set by the user or automatically set by performing an autofocus method when the camera is operating in low light conditions.

Abstract: A method and system for controlling a passage from a secured location to an unsecured location based on presence detection of the unsecured location, including: a radar system in the secure location configured to transmit radar signals to and receive radar signals from the unsecured location; on determination of the presence, by the radar system, of a first person in the unsecured location proximate to the passage, providing an alert. The determination of the presence of the first person in the unsecured location may be triggered by a second person in the secured location moving proximate to the exit or by the second person in the secured location requesting to exit through the passage.

Abstract: A physical security system having multiple server nodes may be built as a distributed network. A first node of the system detects a trigger and a second node of the system detects an input signal that affects a condition to be satisfied prior to performing an action specified by the rule in response to the trigger. A condition evaluation node collects information permitting the condition to be evaluated, and when the condition is satisfied the system performs the action. The first, second, and condition evaluation nodes comprise part of a clustered system, and the condition evaluation node and the second node may be the same.

A positioning module is configured to determine a physical location of the visual object. A deterrence device controller is configured to receive the determined physical location of the visual object, to control a deterrence device to be aimed at the physical location of the visual object, and to control the deterrence device to selectively emit the physical effect.
