  • Patent number: 11539909
    Abstract: Methods and apparatus, including computer program products, for controlling a Pan-Tilt-Zoom (PTZ) camera. A video stream is provided by the PTZ camera. The video stream includes a main image and a smaller picture-in-picture overlay. The main image and the overlay show the same view. The overlay has both a higher frame rate and a lower resolution compared to the main image. A movement control instruction is received, by the PTZ camera, in response to an evaluation of at least one of the main image and the overlay.

  • Patent number: 11381969
    Abstract: Systems and methods are disclosed that provide a secure wireless connection between two electronic devices. Techniques disclosed comprise: generating, on a server, a temporary code; registering, on a first device, the temporary code; sending, from the server to a second device, the temporary code; determining, on the first device, a first temporary credential based on the temporary code; determining, on the second device, a second temporary credential based on the temporary code; establishing, using the first and the second temporary credentials, a temporary connection between the first and the second devices; determining, on the second device, a secure credential; sending, from the second device to the first device, the secure credential via the temporary connection; and establishing, using the secure credential, a secure connection between the first and the second electronic devices.

  • Patent number: 10878850
    Abstract: The present invention relates to a method and apparatus for visualizing information of a digital video stream is disclosed. The apparatus comprises: a memory arranged to store a series of merged image frames which is formed by merging groups of image frames of the digital video stream; a blending module arranged to blend multiple merged frames into a series of blended image frames, wherein each of a plurality of the merged image frames contributes to a plurality of the blended image frames; and a display arranged to display the series of blended image frames.

  • Patent number: 9866787
    Abstract: A method for configuring a plurality of networked cameras includes sending a request to the plurality of networked cameras requesting information relating to enabled storage type of each networked camera, receiving a response from networked cameras. The response includes information relating to storage type enabled in networked camera. The method further includes determining storage type to use for each networked camera that are enabled to autonomously store images at a storage means, where the determining of storage type is performed based on the information relating to enabled storage types received from these networked cameras, and sending a storage instruction to each camera for which a storage type has been determined. The storage instruction instructs a camera to store captured images on a storage means of a specific type.

  • Patent number: 9729835
    Abstract: A method is provided for switching operation of a monitoring system from a first monitoring mode to a second monitoring mode. An overview image is presented when the monitoring system is in a first monitoring mode. A direction signal is received from a control means when the monitoring system is in the first monitoring mode. A camera is directed in an absolute direction indicated by the direction signal in accordance with a first camera control scheme. The monitoring system enters into a second monitoring mode in response to receiving the direction signal presenting a detailed image view captured by the camera when directed in the direction indicated by the direction signal. When in the second monitoring mode, a camera head of the camera is moved in response to control signals from the control means in accordance with a second control scheme.

  • Patent number: 8713643
    Abstract: A method and apparatus are disclosed for configuring access privileges in a system of networked devices. A plurality of access identities is selected and information of access privileges of each of the selected access identities to accessible functions of networked devices is retrieved. The access privileges of the selected access identities for each one of said accessible function of each one of said networked devices is accumulated. The accumulated access privileges are presented for each one of said accessible function of each one of said networked devices in an interface allowing editing of the accumulated access privileges. Change in accumulated access privileges to a specific function in a specific networked device is indicated, and the specific function of the specific networked device is configured for allowing access by the selected users in accordance with the indicated change of accumulated access privileges.

  • Publication number: 20130006571
    Abstract: A monitoring system includes recording units for recording sequences of monitoring data and a system control station. In the system control station, timing information related to each sequence of monitoring data recorded by the recording units is obtained. The timing information indicates a start time and a stop time for each sequence. A recording unit selection signal is received that indicates a selected recording unit. The timing information is processed together with the recording unit selection signal, and a graphic representation of the start and stop times for a subset of the sequences of monitoring data is displayed using a first graphic characteristic. Further, a graphic representation of the start and stop times for each sequence of monitoring data recorded by the selected recording unit is displayed using a second graphic characteristic that is different from the first graphic characteristic.
