摘要： 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 is 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.

摘要： 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.

摘要： An automated security surveillance system ideally 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 at least four audio sensors configured record 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 at least 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.
摘要翻译：自动安全监控系统理想地确定可能的干扰的位置并调整其相机以记录干扰的视频。在一个实施例中，可以通过记录附近区域的音频来确定干扰。耦合到相机的系统可以包括配置为记录附近区域的音频的至少四个音频传感器的布置以产生独立的输出。系统还可以包括处理模块，其被配置为确定音频源相对于至少四个音频传感器的布置的位置的角度和距离。然后，系统可以沿着方位角或仰角旋转调整摄像机，并调整缩放级别以录制音频源的视频。通过使用该系统，监视系统可以通过手动技术更快速和精确地向操作者呈现可能的干扰源的图像。
