  • Database construction of basic elements for displaying CCTV informations(the location, direction, distance, maximum distance, Tele mode angle view, Wide mode angle view, etc.) is conducted by complete survey about CCTV information in model area. Automatic mapping algorithm is suggested to schematize and visualize it on the basic of the investigated CCTV informations. In the result, the CCTV locations in partial areas are duplicated on about 11 percents. Duplicated ones among twelve CCTVs are total five. If the redesign of CCTV location and direction by displaying the CCTV informations based on the suggested algorithm is performed, it can be used as scientific explanations.

  • 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.

  • This is about the CCTV hacking which is one of the recently emerging privacy-spilling crime. Recently, the usage of CCTV is being increased, and Black Hat Hackers spill the individual's privacy by hacking it. However, That crime is being increased. However, most users rarely fulfill the security management, and the government's measures are insufficient. Therfore, this research report implies some security technologies including user authentication protocols such as SSH Tunneling and Media Encryption Algorithm. and recently developed technologies including Wookyeong Information Technology's SecuWatcher for CCTV, Norma's CCTV Care App, and MarkAny's Password SAFERTM for CCTV.

  • Arrest effect of CCTV for crime prevention is very important. CCTV for crime prevention is evaluated as the tools that act efficiently in terms of criminal arrest because CCTV is used later as evidence acting as the eyes of the distance in deserted place. Necessity of CCTV is increasing gradually because of the advantages that obtaining evidence and criminal found arrest is easy. But quality of CCTV is bad and Night Recording is poor. So it is necessary to improve quality of CCTV and Night Recording should be possible for using as crime clues and evidence. In addition, through integrated building control systems of CCTV for crime prevention and extension of retention period it is possible to easily obtain a evidence.

  • The safe return home system automatically tracks and makes a video-recording the client by selecting and controlling CCTV cameras near the client using GPS location information received from the smart device possessed by the service client. This service helps clients to return home safely when there is a crime-ridden district on their late night return home route. If the CCTV cameras that can capture the client are already occupied and used by other clients, concession of occupied CCTV cameras is required to capture the new client. To tackle the limitation, we developed an extended method that considered both the average distances between the client and CCTV cameras and the service rates. As a result, the average distance between CCTV cameras and clients is kept close, and service rates are improved.

  • CCTV Systems have been operated in the variety of serveillance fields of the apartment, transportation, safety, physical security, and so on. And their uses are largely increasing as the CCTV transmission technology has been changed from analog to IP network way. Domestic industry has been working to upgrade from analog CCTV systems to High-Definition(HD) CCTV systems for recent years, which involves a few issues such as mixing with several transmission technologies and duplicated investment in each area because the technological analysis and criteria are specifically not arranged. This paper examines the technical issues of the transmission method between HD analog and HD IP CCTV systems, and induces the criteria of the cost analysis and its weighting factors for HD CCTV reformation. By simulating the cost analysis results of both the HD CCTV systems on apartment environment, this paper proposes the reference for the choice of HD CCTV system reformation.

  • According to the survey of Ministry of the Interior and Safety in Korea, The number of public and private CCTV reached over ten million and is still increasing. Also with improving Image Processing Technology, it is possible to obtain diverse information. Recently, various services using CCTV are being provided. Therefore it is necessary to ensure CCTV image integrity. However there is no system to prove events in film yet. In this paper, we suggest system model that can manage, use and authenticate CCTV. This model allows a CCTV film to be verified by other nearby CCTVs' data. This model ensures film's integrity by using blockchain. And also, It addresses privacy problem in CCTV and file size problem in blockchain by using not large film data but much smaller analyzed data.

  • This study was to evaluate of installation location and management problem for a closed circuit television according to the present situation and installation environment when the CCTV doesn't take a location, surrounding environment, mechanical function in the campus. This methodology used network analysis, mechanical characterization and Streetlight illuminance. As a result, we confirmed in Kyung-Buk National University that was problem of unrelated location of walk pattern in students, a short of illuminance location, only 25 CCTV can be used to crime prevention of student in the night but, the other one is need to some improvement under 44 CCTV.

  • This study practically analyzed the relationships of safety awareness and safety practice of the day-care teacher according to the presence of CCTV and in particular, made a practical analysis about whether safety awareness have mediation effects in the relationship between presence of CCTV and safety practice. As a result of T-test analysis, safety awareness and safety practice of the day-care teacher according to the presence of CCTV is different that has been verified. As a result of regression analysis, safety awareness were positively related to safety practice. That is to say, even the mediation effects that the presence of CCTV through safety awareness related to safety practice were verified. As a result, it was concluded that safety awareness factors didn't play mediator roles between presence of CCTV and safety practice.

  • As CCTV technology develops, it is used in various fields. Currently, we want to know about CCTV operation in detail. In addition, CCTV in many fields is causing problems in operation. We plan to design a new system to solve the problem. In this paper, we analyze data using K-means so that CCTV can be operated efficiently, add new technology and function to existing system to increase image technology and operate efficiently, Technology. In addition, we will design a new system for CCTV technology using k-means so that the CCTV can be efficiently operated in the center, and propose the problem to solve the problem.
