    • A general purpose surveillance system for remote surveillance applications. The system is comprised of one or more audio (e.g., microphone) or video (e.g., camera) surveillance devices that are wirelessly coupled with triggering devices. The system is capable of transmitting audio, video and still pictures via wireless transmission links. The wireless transmission links can be radio frequency (RF) links such as satellite up/down links and commercial cellular networks. Or, the wireless transmission links can be direct line of sight wireless communications such as infrared (IR). The system can be triggered to transmit audio and/or video data either remotely or internally. A variety of sensor types, including but not limited to, infrared sensors, motion sensors, acoustic sensors, magnetic sensors, or electric field sensors can act as a triggering mechanism.
    • 一种用于远程监控应用的通用监控系统。 该系统由与触发装置无线耦合的一个或多个音频(例如麦克风)或视频(例如,相机)监视装置组成。 该系统能够通过无线传输链路传输音频,视频和静态图片。 无线传输链路可以是射频(RF)链路,例如卫星上行/下行链路和商业蜂窝网络。 或者,无线传输链路可以是直接的无线通信,例如红外(IR)。 该系统可以被触发以远程或内部传输音频和/或视频数据。 包括但不限于红外传感器,运动传感器,声传感器,磁传感器或电场传感器的各种传感器类型可用作触发机构。
