摘要

A body detection system using fine movement detection type body detection sensors in a dwelling house capable of solving such a problem that a system cost becomes high because two units of body detection sensors are used in each room to detect stationary personnel in the room or a judgment on presence or absence of personnel in the room is made by using one unit of the sensor in the room and one unit of the sensor in a corridor, wherein, when an exit judgment part (250) does not receive a moving pattern vector comprising a present room ID, a next room ID, and a moving time from an other room reaction detection part (230) within a specified time, the exit judgment part (250) judges to be present in the room and, when the judgment part receives the moving pattern vector from the other room reaction detection part (230), the judgment part judges to be absent in the room only when the moving time in the vector matches the moving time at the time of exit in the past stored in a moving time storage part (240).
