During operation a first personal-area network will activate a first camera. The first camera may be manually activated, or triggered by an audio signal. The event that causes the first camera to activate will also cause the personal-area network to send an acoustic signature to other personal-area networks. Personal-area networks that receive the acoustic signature will modify audio triggers so that the acoustic signature can be better distinguished from other noises.

Method and apparatus for camera activation

Disclosed are methods and systems for providing improved reliability via redundant voting systems. The voting systems are operable to vote on a signal received by a plurality of base stations in a communication system. A first voting processor transmits a message to the plurality of base stations indicating a return base station to voting processor (BS-VP) multicast address. A plurality of multicast messages addressed to the return multicast address are then received from the plurality of base stations and associated with a particular signal received from a signal source by each of the plurality of base stations. The first voting processor determines a recovered signal, and responsive to the first voting processor determining that the second voting processor is no longer operational, transmits the recovered signal to a voting processor to infrastructure (VP-IN) multicast address associated with an infrastructure device and the first and second voting processors.
