Abstract: The present application relates to methods and systems for including sensor data from a sensor unit (108) as an overlay (204) in a video stream from a camera (106) monitoring a scene (200). The overlay has overlay regions (206a-f) corresponding to scene regions (202a-f), and when the sensor unit detects motion in a scene region a graphical element (208) is added to the overlay in the overlay region corresponding to that scene region. Video analytics procedures, such as object feature detection or motion or change detection may then be used to determine if detection has been made in a specific scene region by both the camera and the sensor unit.

Abstract: A monitoring camera includes a camera lens, an image sensor, and a housing enclosing the image sensor. The housing encloses a volume of Phase Changing Material (PCM) having the characteristic of not beginning a phase change until its temperature rises above a predetermined phase changing temperature. The phase changing temperature is in the range of 20-80 degrees Celsius, and the PCM is arranged to enclose the camera lens.

Abstract: An image processing device a camera and a method for of encoding images captured by a camera are disclosed. For each image of an image sequence captured by the camera, the image is pre-processed by filtering the image by applying a privacy filter, the privacy filter being configured to distort the image in such a way that privacy is achieved in the filtered image, and, for at least a subset of the filtered images, by colour revising the filtered image by changing colour of pixels of a plurality of scattered areas of the filtered image such that a respective colour of one or more pixels of each area of the plurality of scattered areas represents one or more original colours of one or more pixels before filtering at a location of that area in the filtered image. The pre-processed images are then encoded into an encoded video stream.

Abstract: A method for anonymizing a digital colour image comprising obtaining the digital colour image, and applying a linear random function to a respective colour vector representing colour components of a respective pixel of the digital colour image to obtain a monochrome image. The linear random function varies over the pixels of the digital colour image, and is further dependent on at least one random parameter.

Abstract: There is provided a camera and a method therein for facilitating installation of the camera. The method comprises capturing a video stream of a scene when the camera is installed with a first FOV, which scene comprises an object. A size in the video stream of at least one part of the object is estimated. As long as the estimated size is above a first threshold and below a second threshold, providing a first, edge-filtered, version of the video stream to secure privacy of the object. In response to the estimated size being above the second threshold indicating that the privacy is at risk of being revealed, entering an enhanced secure privacy mode comprising generating an alert to prompt an installer to re-install the camera with a second FOV different from the first FOV, and disabling provision of the first, edge-filtered, version of the video stream.

Abstract: The present invention discloses a method of injecting additional data in one or more image sensor frames in an image sensor device. The method comprises: providing (801) additional data in the form of a numeric sequence, controlling (802) the lengths of subsequent blanking intervals in one or more image sensor frames to represent the numeric sequence, and transmitting the one or more image sensor frames from the image sensor device. The one or more image sensor frames may be transmitted to an image processor (12, 72). Examples of image processors (12, 72) and a system (1, 7) comprising an image processor (12, 72) are also disclosed.
