| Summary: | 碩士 === 國立臺北大學 === 犯罪學研究所 === 97 === Ever since the National Police Agency, Ministry of The Interior started implementing the community safeguard program, all government branches and police offices began integrating community resources, promoting the importance of public security, and establishing a community security system. The next milestone in the program is to construct a nationwide Closed Circuit Television (CCTV).
It is clear, the CCTV will play a crucial role in the community safeguard program. Thus, how the CCTV should be constructed, so that it can continuously aid the investigative efforts as policing methodologies keep evolving becomes an important topic to address.
This study investigated four aspects pertaining to the CCTV currently deployed in the city of Taipei: 1) the overall perception for the CCTV; 2) integrating the CCTV with defensible space practices; 3) influences of the CCTV on privacy; and 4) management for CCTV camera placements. Questionnaires were utilized to collect data for analyses, and the sample population included all staffs at the Department of Civil Affairs, Taipei City Government & Taipei City Police Department (including the head and the director of the CCTV service division), heads of all Taipei City subdivisions, staffs of all Taipei City precincts, and citizens of the Taipei City. A total of 894 questionnaires were sent out, and 607 valid questionnaires, or 67.90 percents of total questionnaires, were collected. SPSS 12.0 (for windows) was used to conduct statistical analyses, and the primary statistical analyses performed include: frequency distribution, factor analysis, T test, one-factor analysis of variance, and regression analysis.
The study revealed that: 1) respondents deemed that the CCTV will definitely improve security for the neighborhoods; 2) respondents are not totally satisfied with the crime-deterring effects of the CCTV; 3) the video resolution of the CCTV should be improved; 4) accessing policies for the CCTV tapes should be strictly reinforced, and respondents from safe neighborhoods are more satisfied with the tape accessing policies; 5) respondents hold positive viewpoints toward informal surveillance; 6) respondents feel comfortable that public areas are under surveillance for the purpose of public safety; 7) the CCTV does not violate privacy; 8) respondents perceive that it will make a positive contribution to public safety if the government constructs a nationwide CCTV; 9) respondents perceive that it is very important to enforce well thought out management policies for the CCTV; 10) respondents hold positive viewpoints toward replacing the CCTV with other safety improvement mechanisms; 11) respondents perceive that the camera placements should be more effect-driven; and 12) respondents do not agree that current CCTV can function reliably.
Finally, the results from the regression equation of a well conceived CCTV indicate that the CCTV should possess the following qualities: 1) a high level of acceptance for camera placements; 2) a high degree of performance satisfaction; 3) a high quality of the tape resolution; 4) a positive image in the mind of citizens; 5) a positive perception and readiness for informal surveillance; 6) perceptions of effective crime prevention; 7) camera placement that is crime-deterring oriented; and 8) a high level of functional reliability. These findings can serve as references for constructing a CCTV that will effectively assist police forces in the future.
