Abstract: A housing for an electronic device. The housing includes a first shell at least partly enclosing the electronic device, a second shell, and at least a first fan. The first shell is arranged to allow a gaseous fluid to surround the electronic device. The second shell at least partly encloses the first shell, and is arranged in relation to the first shell such that the gaseous fluid may be present between the shells. The at least first fan is arranged in an opening of the first shell such that it is capable of providing a flow of the gaseous fluid through the opening in the first shell of the gaseous fluid to the second shell and thereby provide heat transport from the electronic device to the second shell.

Abstract: The invention relates to a calibration method in a camera with a P-Iris lens having an adjustable iris opening.

Abstract: An integrated Internet camera includes, as embedded components contained within the camera body and controlled by a microcontroller, at least a network interface device for connecting to the Internet, a transport control device for packetizing according to Internet protocols, a file transfer device for communicating with a destination user directory on the Internet, and a transmission initiating device for initiating the connection and transfer operations of the file transfer device and transport control device. The network interface device may be a modem, network adapter, or adapter for connection to the Internet. Upon capturing the digital image, the camera initiates a connection to the Internet, connects to the destination user directory, and uploads the digital images. Thereafter, the digital images are available to authorized (or any) user having access to the Internet.

Abstract: A camera, connectible to a CCTV network, includes a camera lens and image sensor. as well as an analog video input connector that receives analog image signals corresponding to views from outside the camera. An image processing circuit outputs image signal data of the image sensor, and a video conversion circuit outputs image signal data of the analog image signals. The image signal data is stored on a storage device. A microcontroller controls the circuits, and a network adapter connects to an internet-protocol address corresponding to a network device capable of serving files. The microcontroller selectively transmits image signal data of the image sensor or transmits image signal data of the analog video input connector from the storage device to the network device using the network adapter and the internet-protocol address.

Abstract: A method for restricting access to media data generated by a camera comprising: setting a non-public initial user key, KICU, in the camera, providing a user client with the initial user key, KICU, establishing an authenticated relation between the user client and the camera by sending an authentication message including information based on the initial user key, KICU, from the user client to the camera, checking if an operational user key (KOCU) is set in the camera, and performing, in response to the act of checking if the operational user key (KOCU) is set in the camera, the acts a)-d) only if the operational user key (KOCU) is not set: a) acquiring an operational user key (KOCU), b) setting the operational user key (KOCU) in the camera, c) sending the operational user key (KOCU) to the user client, and d) indicating in the camera that the operational user key (KOCU) is set.

Abstract: The invention relates to a method of transmitting a first segment of data via a data network from a transmitting unit having a first data transmission rate to a first destination having a first data reception rate. Where the first data transmission rate is larger than the first data reception rate, the method comprising: effectively reducing the first transmission rate from the transmitting unit to the first destination by switching between transmitting at least a part of the first segment as one or more data packets to the first destination in a direction only from the transmitting unit to the first destination, and transmitting at least a part of second segment as one or more data packets to one or more additional destinations in a direction only from the transmitting unit to the one or more additional destinations, the switching being repeated until said first segment and/or at least said second segment has been transmitted.

Abstract: A camera assembly includes a camera arranged to be panable and tiltable, and a transparent view port cover. The transparent view port cover includes a first part and a second part arranged together to present different angles of view to the camera, the second part having a lens.

Abstract: A processor and associated methodology employ a SIMD architecture and instruction set to efficiently perform video analytics operation on images. The processor contains a group of SIMD instructions used by the method to implement video analytic filters that avoid bit expansion of the pixels to be filtered. The filters hold the number of bits representing a pixel constant throughout the entire operation, conserving processor capacity and throughput when performing video analytics.

Abstract: A video analytics system and associated methodology for performing low-level video analytics processing divides the processing into three phases in order to efficiently use SIMD instructions of many modern data processors. In the first phase, pixels of interest are gathered using a predetermined mask and placed into a pixel matrix. In the second phase, video analytics processing is performed on the pixel matrix, and in the third phase the pixels are scattered using the same predetermined mask. This allows many pixels to be processed simultaneously, increasing overall performance. A DMA unit may also be used to offload the processor during the gathering and scattering of pixels, further increasing performance. A network camera integrates the video analytics system to reduce network traffic.

Abstract: A system, computer program product and associated methodology for video motion detection combines a series of images of a video sequence into an image volume having vertices of X, Y and t. The image volume is sliced in either the (X,t) or (Y,t) planes, filtered with a spatio-temporal filter and thresholded to reduce the amount of information. Then a search algorithm searches along search lines in a subset of the video sequence to locate motion. Motion can be detected by identifying lines that are not parallel to any of the vertices. Stationary subjects and lighting changes appear as lines parallel to one of the vertices. Thus, true motion can be distinguished from lighting changes.

Abstract: A network connector device and a method for making image information sent through a first digital network accessible by a second digital network. A first and a second network connector are arranged to pass on digital network traffic, a network traffic buffer buffers the digital network traffic, an image session identifier identifies a network session from the buffered digital network traffic, containing image information. An image session tracker tracks the identified network session containing image information, an image extractor extracts image information from the identified network session containing image information, and an image information buffer buffers the extracted image information. An image information arranger arranges the image information from the image information buffer into at least one image sequence of related images, and a server makes accessible the at least one image sequence via a third network connector.
