1. A signal detection apparatus comprising:

  • a sensor that detects a signal;

    a clock that is synchronized with another clock incorporated in another signal detection apparatus;

    a first generator that generates first feature information representing a feature of a frequency domain of a signal block obtained by performing block formation of the signals from the sensor at every predetermined time based on time information of the clock;

    an allocator that allocates priority levels to a plurality of signal characteristics of the signal block;

    a second generator that generates second feature information representing a feature of a time domain of the signal block for each of the plurality of signal characteristics;

    a receiver that receives a server command indicating a bandwidth allocated by a server apparatus from the server apparatus;

    a limiter that, if a total information volume of the pieces of second feature information exceeds an upper limit information volume corresponding to the bandwidth, selects some of the pieces of second feature information and discards remaining pieces of second feature information based on the priority levels allocated to the pieces of second feature information to limit an information volume of the selected pieces of second feature information not to exceed the upper limit information volume; and

    a transmitter that transmits the first feature information and the selected pieces of second feature information to the server apparatus.
