    • A method of supervising intruder alarm systems, each alarm system comprising a plurality of alarm sensors and at least one gateway communicating with a remote alarm receiving centre. The method includes the steps: a) receiving in a first intruder alarm system radio signals transmitted from a second intruder alarm system, b) transmitting from said first intruder alarm system information relating to the received radio signals to said remote alarm receiving centre, c) analysing in said remote alarm receiving centre information received from intruder alarm systems to identify at least one first intruder alarm system and at least one second intruder alarm system capable of exchanging information via radio signals, d) transmitting from said remote alarm receiving centre control signals to said first intruder alarm system and to said second intruder alarm system to operate as a supervising system by monitoring radio signals from the other intruder alarm system operating as a supervised system, e) observing in either one of said first intruder alarm system and said second intruder alarm system absence of the monitored radio signals, and f) transmitting from a supervising alarm system an alarm signal when absence of said monitored signals is detected.
    • 一种监视入侵者报警系统的方法,每个报警系统包括多个报警传感器和至少一个与远程报警接收中心通信的网关。 该方法包括以下步骤:a)在第一入侵者报警系统中接收从第二入侵者报警系统发送的无线电信号,b)从所述第一入侵者报警系统发送与所接收的无线电信号有关的信息给所述远程报警接收中心; c) 在所述远程报警接收中心中分析从入侵者报警系统接收到的信息,以识别至少一个第一入侵者报警系统和能够经由无线电信号交换信息的至少一个第二入侵者报警系统,d)从所述远程报警接收中心控制信号发送到 所述第一入侵者报警系统和所述第二入侵者报警系统通过监视作为监督系统操作的其他入侵者报警系统的无线电信号来操作作为监督系统,e)在所述第一入侵者报警系统和所述第二入侵者报警系统 监控的无线电信号的报警系统不存在,以及f)从监督的传输信号 当检测到不存在所述监视信号时,警报系统发出报警信号。

    • An unattended sensor is provided for use in a surveillance system. The sensor is generally comprised of: a detector that generates an electrical signal in response to a physical stimulus proximate to the sensor; a signal processor adapted to receive the electrical signal from the detector and operable to generate an event message based on the electrical signal; a transceiver operable to send and receive messages over a wireless radio link; and a channel access mechanism operable to negotiate access to the radio link in accordance with an access protocol, where the access protocol is employed by radios and other communication devices in the system.
