摘要:AbstractAttempts on the introduction of systems of the e-JIKEI Network, a novel concept on operating security camera system, are reviewed. The concept of the e-JIKEI Network is that a community will have a strong ability to prevent crime only if some residents keep watch their surroundings. Community safety would be realized by the voluntary cooperation and altruism of citizens. Before introducing the systems, altruistic mind of the citizens has been enhanced, and consequently, the systems have been successfully introduced to residential districts and schools. The prospects for the concept of the e-JIKEI Network are discussed.
