This study points out how the police administration is supposed to make plans on three main objectives of maintaining social security, that is, “preventing crimes,” “community police administration,” and “the police administration of digital technology system.” And this research is undergone in terms of realistic social environments and social control. The communities’ technologically constructed envelopment system, which can transmit images, sounds, and data through wireless microwave internet, is combined with police inspection of fixed spots and moving police force to make an immense communication network for the prevention of crime. Moreover, the envelopment system can also work with the taxi drivers’ organization (of wireless radio stations) to maintain social security. The overall security systems consist of “enlarged joint system of community’s security,” “envelopment system,” and police’s daily duties. This study proves that since the implementation the envelopment project in 2002, Taoyuan City’s Police Precinct Office has apparently reached the goals of preventing crimes, reducing crime rate, and improving the service quality. It has been rapidly cracking various kinds of criminal cases to forge a much more harmonious and peaceful environment.
