지난 봄, 한 아파트의 엘리베이터 안에서 괴한이 아이를 납치하기 위해 폭행하는 장면이 CC TV에 찍혀 온 나라를 들썩이게 했다. 그 때 범인을 검거하는 데 기여한 일등 공신이 CC TV(폐쇄 회로 텔레비전)였다. 이를 계기로 공동 주택을 포함한 주택가에 CC TV를 비롯한 각종 보안 장비를 설치해야 한다는 목소리가 대두되면서 관련 법 개정이 이뤄질 전망이다.

CCTV(Closed Circuit Television : 폐쇄회로텔레비전)는 산업, 교육, 교통관제, 범죄예방 등의 다양한 목적으로 이미 많은 분야에 활용되고 있다. CCTV의 사용목적이 다양화되면서 CCTV로부터 촬영된 영상데이터는 굉장히 중요한 자료로 사용된다. CCTV는 영상 및 음성 데이터를 특정 사용자에게 전송하는 시스템으로 수신대상 이외에는 수신할 수 없도록 구성되어 있다. 이러한 CCTV 운영 시스템은 제 3자가 폐쇄회로 내부에 접근한 경우에 대한 보안이 취약하다. 즉 제 3자가 폐쇄회로 내에 접근하게 되면 데이터 포획, 데이터 위 변조가 쉽게 이루어 질 수 있다. 본 논문에서는 폐쇄회로 내에서 인가되지 않은 기기 및 공격자에 의한 데이터 포획, 데이터 위 변조 방지를 위한 프로토콜을 제안한다.

인구 및 차량 증가에 따라 날로 심각해지는 교통문제를 해결하기 위해서는 도로를 건설하는 방법만으로는 한계가 있음을 인식하여 새로운 도로의 건설보다는 도로의 교통효율을 높이고 안전성을 확보하는 것이 더욱 중요한 문제로 대두됨에 따라 저비용 고효율의 교통관리방안인 지능형교통체계(ITS)를 추진하였다. 이에 국가기간망인 국도의 ITS 구성과 차량검지기(VDS), 차량번호인식장비(AVI), 폐쇄회로텔레비전(CCTV), 도로전광표지(VMS) 등 주요장비의 구성을 통한 국도 ITS를 이해하고, 국도 ITS 구축 현황 및 계획, 그 효과를 살펴보고 비전을 제시함으로서 향후 추진해야할 개선방안을 제안하였다.

Due to the event of hazardous chemical injection into a water storage tank in Hongseong, Chungcheongnam-do in 2012, the Korean Ministry of Environment has revised the enforcement rules of the Water Supply and Waterworks Installation Act to install surveillance equipments such as closed-circuit television(CCTV). However, the enforcement rules still do not provide concrete provision for installation of physical security equipments. Thus we studied vulnerability of small-scale water supplies in Korea and developed guidelines for the physical security system of the facilities. The guidelines include selection and recommendation of the physical security approaches and measures to detect, delay and response to the presence of an intruder in small-scale water supplies. The security features include protection utilities(e.g., fencing and fence topping), exterior intrusion detectors and alarms, locks and padlocks, surveillance utilities(e.g., CCTV), and others.

We made a smartphone interlocking location tracking streetlight and remote display device to compensate the defect of real time identifiable CCTV streetlights and child safety notification applications. It controls brightness of LED by detecting the surrounding brightness and objects with ultrasonic sensor and illuminance senor. The CCTV receives the location of smartphone by Bluetooth and takes the target of the location. It realizes a wireless transmission system that the video is upload to the tablet PC via WiFi.

The Chemical Control Act has revised in 2015 to promote chemical safety, particularly enhancing the standards for the installation and management of hazardous chemical handling facilities. However, in some existing facilities, it was difficult to comply with some facility standards because of lack of land, safety accident possibility during rebuilding. In this study, we attempted to provide a more rational approach of dike standard which was the highest(2017: 117, 2018: 83) complaint for two years(2017~2018, 1,087) by prior study, FLACS simulation, analyze safety management standard and conduct a survey. Therefore, considering the purpose of installing the discharge wall only at existing facilities in operation, additional sensors that can detect chemical leakage and leakage were recognized as an additional alternative to installing and operating closed circuit television (CCTV). This will help the safety and cost aspects of small or medium-sized businesses or small and medium-sized enterprises that cannot secure legal grounds or fail to enforce legal regulations due to economic problems such as construction costs.

In this paper, we propose IoT based smart CCTV security service to prevent crime in blind spot and prevent unexpected fire or danger. In the proposed method, a RC (Radio Control) car is made using Raspberry pie, and a camera and various modules are installed in an RC car. It was then implemented using Raspbian O / S, Apache Web Server, Shell script, Python, PHP, HTML, CSS, Javascript. The RC car provides a security service that informs the manager of the situation by judging the risk of the scene with modules such as video, voice and temperature. Experimental results show that the transmission time of video and audio information is less than 0.1 second. In addition, real-time status transmission was possible in AVG, emergency, and manual mode. It is expected that the proposed method will be applied to the development of smart city by applying it to unmanned vehicles, drones and the like.

When an applicant requests the emergency situation call or safe return service using a smart device, the smart surveillance service can select the CCTV(closed circuit television) cameras around the applicant using applicant's location information, then automatically takes a photograph to track the applicant. Since the surrounding CCTV camera shoots the applicant continuously using location information and the applicant can be observed by the monitor agent in real time, this service can be very helpful in an applicant's emergency situation or safe return. The existing smart surveillance service does not consider the priority of the emergency situation call and safe return service. Therefore, there is the disadvantage that the applicant who requests an emergency situation call service can not be photographed when safe return service has already preoccupied CCTV cameras which are capable of taking a picture of the applicant. The proposed smart surveillance service improves this disadvantage by using service priority.
