A cooperative crime prevention system is provided to enable the other indoor transceiving terminal or a portable transceiving terminal within a predetermined area to transmit a signal transmitted from an indoor transceiving terminal so that other terminals within the predetermined area are able to receive the signal. A cooperative crime prevention system comprises plural invasion sensors(110), an indoor transceiving terminal and a portable transceiving terminal(200). The plural invasion sensors are installed at inside or outside of a home. The indoor transceiving terminal informs invasion information through a signal output unit if an invasion signal is received from the invasion sensors. The indoor transceiving terminal transmits an invasion signal to the other terminal within a predetermined area. If the invasion signal is received from the indoor transceiving terminal, the portable transceiving terminal informs the invasion information through the signal output unit. The indoor transceiving terminal or the portable transceiving terminal transmits the received signal to the other terminals within a radiowave arrival distance. The portable transceiving terminal transmits an operation unavailable signal to the indoor transceiving terminal before operations become unavailable if the portable transceiving terminal is not operated.
