  • Patent number: 10931920
    Abstract: Traditional approaches to automated monitoring using a pan-tilt-zoom (PTZ) video security system involve the use of programmed patterns/preset tours. In contrast, a camera tour is configured based on operation of a surveillance system during a period of active operation by a user. The configuration accounts for frequency of given views and other measures to provide an automated tour. The automated tour is displayed when the system is not under active control, and can be updated during further periods of active control.

  • Patent number: 10893201
    Abstract: A method and system are provided to perform electronic image stabilization of images captured by an image sensor on a camera device. In the method and system, non-linear motion of a camera device is measured with a motion sensor during an exposure time for each line of a frame captured by the image sensor of the camera device. A first line of the frame has a first exposure time, and subsequent lines of the frame have an exposure time that is later than a previous line of the frame, each line of the frame having an associated position in the frame. The position of each line of the frame is adjusted based, at least in part, on the measured non-linear motion to create a modified frame that corrects for non-linear motion that occurred for each line of the frame.

    Abstract: A system and method is provided to measure latency on a video management system having a computer system and a camera. The computer system initiates a presentation of a video stream comprising a plurality of video frames on a display device. Each video frame of the video stream includes a changing image which represents frame information for tracking the video frame. The computer system receives a live video stream representative of the presented video stream from the camera, which is directed at an output of the display device to capture in real-time the presented video stream. The image of one or more video frames of the received stream is processed to identify the frame information from the one or more video frames. The end-to-end latency of the video stream is determined based on at least identified frame information of the one or more video frames of the received stream.

  • Patent number: 10750132
    Abstract: An automated security surveillance system determines a location of a possible disturbance and adjusts its cameras to record video footage of the disturbance. In one embodiment, a disturbance can be determined by recording audio of the nearby area. A system, coupled to a camera, may include an arrangement of four audio sensors recording audio of the nearby area to produce independent outputs. The system further may include a processing module configured to determine an angle and distance of an audio source relative to a location of the arrangement of the four audio sensors. The system can then adjust the camera by rotation along an azimuth or elevation angle and adjusting the zoom level to record video of the audio source. Through use of the system, a surveillance system can present an image of a source of possible disturbance to an operator more rapidly and precisely than through manual techniques.

  • Patent number: 10009579
    Abstract: A sensor system according to an embodiment of the invention may process depth data and visible light data for a more accurate detection. Depth data assists where visible light images are susceptible to false positives. Visible light images (or video) may similarly enhance conclusions drawn from depth data alone. Detections may be object-based or defined with the context of a target object. Depending on the target object, the types of detections may vary to include motion and behavior. Applications of the described sensor system include motion guided interfaces where users may interact with one or more systems through gestures. The sensor system described may also be applied to counting systems, surveillance systems, polling systems, retail store analytics, or the like.

  • Patent number: 9843903
    Abstract: Because GPS does not work indoors, mobile electronics devices that use GPS for activities do not work inside a building. An embodiment of the present invention uses ultrasonic tone generators in each room. The ultrasonic tone generators can be built into cameras or separate devices. Each device may emit a unique tone that has a high enough frequency that most people cannot hear the frequency or combination of frequencies. Using a built-in microphone on a mobile device, the incoming audio may be analyzed in the frequency domain to determine the loudest tone above the human hearing threshold. This tone may be mapped to a specific room that can then be sent to the mobile electronics device to perform any location-aware actions.
