This study aims to investigate the possibility of crime prevention through CCTV by analyzing the appropriateness of the CCTV location, whether it is installed in the hotspot of crime-prone areas, and exploring the crime prevention effect and transition effect. The real crime and CCTV locations of case city were converted into the spatial data by using GIS. The data was analyzed by hotspot analysis and weighted displacement quotient (WDQ). The results demonstrated that there was no significant effect in the installation of CCTV on crime prevention. This indicates that CCTV should be installed and managed in a more scientific way reflecting local crime situations. In terms of CCTV, the methods of spatial analysis such as GIS, which can evaluate the installation effect, and the methods of economic analysis like cost-benefit analysis should be developed. In addition, these methods should be distributed to local governments across the nation for the appropriate installation of CCTV and operation. This study intended to find a design guideline of the optimum CCTV installation. In this regard, this study is meaningful in that it will contribute to the creation of a safe city.

CCTV(Close Circuit Television)는 화상정보를 특정 목적으로 특정 사용자에게 전달해주는 시스템이다. 회사, 쇼핑몰 등 큰 규모의 건물부터 아파트, 개인 상점에 이르기까지 많은 분야에서 CCTV를 설치하여 건물 내외의 영상을 촬영하여 보안을 위해 사용한다. 하지만 기존의 CCTV 시스템을 설치하기 위해 필요한 장비가 고가이기 때문에 일반 가정에서 CCTV를 설치하여 사용하기에는 경제적 부담이 있다. 그리고 CCTV를 제어하고 영상을 저장하기 위한 장비의 전원을 계속 켜두어야 하기 때문에 CCTV 시스템의 유지 및 사용하는데 드는 비용도 비싸다는 단점이 있다. 이 문제점들을 해결하기 위해 본 논문에서는 일반 가정에서 많이 사용하는 무선 공유기와 웹 카메라를 사용해서 가정용 CCTV 시스템을 설치하는 방법을 제안하고 구현한다. 제안된 방법은 무선 공유기에 웹 카메라를 연결하여 CCTV 시스템을 구현하고, 움직임이 감지될 경우 SMS 서비스를 사용하여 사용자에게 경고 메시지를 전송함으로써 저렴한 비용으로 침입에 대한 즉각적인 대응을 할 수 있는 서비스를 제공하는데 목적이 있다.

현재 CCTV는 범죄의 예방 목적이 아닌 증거물 확보용으로 많이 활용되고 있으며, 범죄 예방을 위해서는 더 많은 CCTV를 설치해야한다. 하지만 추가적인 CCTV 설치는 사생활 침해를 초래하며, CCTV 관리자는 여러 대의 CCTV 화면을 파악하고 분석해야하는 어려움이 있다. 이를 해결하기 위해 본 연구에서는 CCTV와 스마트폰의 GPS기능을 연계하여 범죄 예방 목적을 갖는 지능형 CCTV 시스템을 제안한다. 제안한 시스템을 통해 관리자 및 유관기관은 범죄 발생을 빠르게 판단하고 CCTV가 범죄 발생 영상을 보호자에게 전송하여 범죄 발생을 사전에 차단할 수 있다.

Recently, according to the rapid development of surveillance information, closed-circuit television (CCTV) has become an indispensable component in security systems. A lot of advanced technologies of encryption and compression are implementing to improve the performance and security levels of the CCTV system. Especially, 360 video CCTV streaming is promising for surveillance without blind areas. However, compared to previous systems, 360 CCTV requires large bandwidth and low latency. Therefore, it requires more efficiently effort to improve the CCTV system performance. In order to meet the demands of 360 CCTV streaming, transcoding is an essential process to enhance the current CCTV system. Moreover, encryption algorithm is also an important priority in security system. In this paper, we propose a real-time transcoding solution in combination with the ARIA and AES algorithms. Experimental results prove that the proposed method has achieved around 195% speed up transcoding compared to FFMPEG libx265 method. Furthermore, the proposed system can handle multiple transcoding sessions simultaneously at high performance for both live 360 CCTV system and existing CCTV system.

This study aims to establish a simulation method for CCTV (Closed Circuit Television) sight area. The simulation incorporates variables for computing CCTV sight area including CCTV specifications and installation. Currently CCTV is used for traffic, crime prevention and fire prevention by local governments. However, new locations are selected by administrator decision rather than analysis of the optimal location. In order to determine optimum location, a method to CCTV compute range is needed, which incorporates specifications according to CCTV purpose. For this purpose, limitations of previous research methods must be recognized and the simulation method must supplement these limitations. Here in this study, we derived CCTV sight area variables for realistic analysis to complement the limitations of previous studies. A total of eight elements were derived from image device sensors and installation: wide angle, height, angle, setting height, setting angle, and others. This research implemented a 3D simulation technique that can be applied to the derived factors and automate them using ArcObject and Visual C#. This simulation method can calculate sight range in accordance with CCTV specifications. Furthermore, when installing additional CCTVs, it can derive optimal allocation position. The results of this study will provide rational choices for specification selection and CCTV location by interagency collaborative projects.

The purpose of this paper is to analyze various categories such as the recognition, expectation and acceptability of CCTV use in educational facilities by doing a survey on how college students think about the CCTV installed in educational facilities. For this research, diverse existing surveys regarding CCTV were examined, and the appropriate elements of survey questions were extracted and developed. Based on this method, we intend to complete a survey study hereafter on the change in perception regarding CCTV inspection. We made four hypotheses before the survey and the results of the survey are as follows: First, the expectations for CCTV's ability to reduce crime were high. Second, the fears about being a victim of theft or violence crime were decreased. Third, there were a number of respondents who would weigh more on increased safety by installing a CCTV rather than be concerned that CCTV may lead to the violation of students' human rights. Fourth, there showed a difference in recognizing CCTV among three groups. Also, for the questions regarding the places where CCTV is installed, there were many negative opinions on its installation in the student convenient facilities. What we have achieved was not a simple survey which investigates the pros and cons about CCTV use, but a newly suggested way of survey, which enables us to test various hypotheses and figure out the changing perceptions on CCTV effectiveness in educational facilities with more efficiency.

In this paper, we introduce a smart care surveillance system which can support various CCTV cameras. In order to monitor an emergency requester in case of emergency, the server performs automatical CCTV Pan, Tilt, and Zoom control based on the location coordinates of the emergency requester. Also, a server finds and tracks the emergency requester using image processing and the updated location information. We implement a smart care surveillance system using the Genetec SDK tool to support various CCTV cameras. The efficiency of the rescue operation with the smart care surveillance system can be improved because rescuer can quickly control and monitor the requester's CCTV images.
