1. A surveillance system that monitors transfer of data comprising:

  • an input node capturing a state of an item to be monitored;

    an outputting information representing said state of said item to be monitored;

    a control node controlling said input node and said output node; and

    a network transferring data between said input node, said output node, and said control node;

    wherein said control node determines a transfer capacity for a first type of data to be transferred uniformly over time, a total of said transfer capacity being no greater than a prescribed amount smaller than a total transfer capacity of said network;

    if said input node, said output node, of said control node performs transfer of said first type of data, said data is transferred at a transfer rate corresponding to said determined transfer capacity; and

    if said input node, said output node, or said control node performs transfer of a second type of data for non-uniform transfer over time, said data is transferred at a transfer rate corresponding to an available capacity of said network.
