IP camera which transmits image signal in network includes web server, network interface unit and CCD(Charge-Coupled Device) module. IP camera is able to transmit image signals by network in real time and to monitor the scene image always by IP or Web address. IP camera is substituted for analog camera now gradually according to the development and progress of camera technology and expect it to extend the boundary in rolling stock gradually cause of the excellent expansibility and noise solution of analog camera. We survey the IP camera system composition in rolling stock and so this can be a help to develop and design IP camera system, because it has unsolved problems for common use of IP camera.

IP카메라는 CCTV와 달리 값도 저렴하고 네트워크와 연결돼 PC와 스마트 폰을 통해서 실시간 조회 및 제어가 가능한 카메라이다. 이러한 장점에 힘입어 일반 가정이나 매장 등에서 도난 방지 및 감시를 위해 IP 카메라를 사용하는 사람들이 급격히 증가하고 있으며, 이에 따라 해킹을 통한 사생활 침해 문제도 같이 증가하고 있다. 이는 사용자들의 보안 인식이 턱없이 부족해 전문가가 아니더라도 손쉽게 프로그램과 사이트를 이용하여 해킹이 가능하기 때문인 것으로 사료된다. 따라서 본 논문에서는 해킹이 얼마나 쉽게 이뤄지는지, 어떠한 피해가 있는지, 그리고 이에 대한 해결방안을 제안한다.

ICT 기술의 빠른 발전과 함께 Internet of Things (IoT) 환경에서의 Internet Protocol (IP) 카메라의 사용률이 증가하면서, IP 카메라에 대한 개인정보 이슈와 제품의 보안성 검토 관련 소비자의 개인정보 유출 우려가 증가하고 있다. 본 논문에서는, IP 카메라에 대한 4개 종류의 Denial of Service (DoS) 공격을 통해 IP 카메라 이상 반응을 확인했다. 또한, 이 과정에서 수집한 공격 패킷 데이터를 기반으로, DoS 공격을 탐지하는 간단한 피쳐 구성과 머신러닝 모델을 제안하였다. 최종적으로, DoS 공격을 통해 실제 IP 카메라에 대한 가용성 테스트를 수행하였으며 머신러닝 알고리즘 4개 Decision Tree, Random Forest, Multilayer Perceptron, SVM에서의 DoS 공격 탐지 성능을 비교하였다.

Cyber attacks are increasing worldwide, and attacks on personal privacy such as CCTV and IP camera hacking are also increasing. If you search for IP camera hacking methods in spaces such as YouTube, SNS, and the dark web, you can easily get data and hacking programs are also on sale. If you use an IP camera that has vulnerabilities used by hacking programs, you easily get hacked even if you change your password regularly or use a complex password including special characters, uppercase and lowercase letters, and numbers. Although news and media have raised concerns about the security of IP cameras and suggested measures to prevent damage, hacking incidents continue to occur. In order to prevent such hacking damage, it is necessary to identify the cause of the hacking incident and take concrete measures. First, we analyzed weak account settings and web server vulnerabilities of IP cameras, which are the causes of IP camera hacking, and suggested solutions. In addition, as a specific countermeasure against hacking, it is proposed to add a function to receive a notification when an IP camera is connected and a function to save the connection history. If there is such a function, the fact of damage can be recognized immediately, and important data can be left in arresting criminals. Therefore, in this paper, we propose a method to increase the safety from hacking by using the connection notification function and logging function of the IP camera.

In this paper, the TDMA-based PoE wireless multi-IP camera transmission system using wireless communication technology is developed to reduce the burden of construction costs caused by the existing wired-based CCTV surveillance system and IP camera system. It intends to design and implement the long-distance wireless transmission technology of video. The transmission/reception prototype of the line IP transmission system and the wireless multi-IP camera transmission terminal and image acquisition device (SB-200) for the proposed related technology were described.

Currently widely used IP cameras provide the ability to control IP cameras remotely via mobile devices. To do so, the IP camera software is installed on the website specified by the camera manufacturer, and authentication is performed through the password between the IP camera and the mobile device. However, many products currently used do not provide a secure channel between the IP camera and the mobile device, so that all IDs and passwords transmitted between the two parties are exposed. To solve these problems, we propose an authentication and key exchange protocol using ID-based signature scheme. The proposed protocol is characterized in that (1) mutual authentication is performed using ID and password built in IP camera together with ID-based signature, (2) ID and password capable of specifying IP camera are not exposed, (3) provide forward-secrecy using Diffie-Hellman key exchange, and (4) provide security against external attacks as well as an honest-but-curious manufacturer with the master secret key of the ID-based signature.

In this paper, the design and implementation of the long-distance wireless transmission technology of high-definition video using domestic wireless communication technology for the existing wired-based CCTV surveillance system and IP camera system was evaluated for performance. The interworking test between the wireless multi-IP camera transmission terminal device and the wireless communication RF module, and the wireless multi-IP camera-based video transmission system integration interworking test confirm the module interworking suitability during video transmission.

현재 각 나라의 항만관련 부서는 자국의 항만을 국제항으로 발돋움시키기 위하여 항만보안 시스템을 구축하고 있는 실정이다. 최근 인천항에서도 감시체제가 인력경비에 의존하던 방식에서 벗어나 영상보안 시스템을 활용하는 중앙감시체제로 바뀔 전망이다. 이러한 인천항의 항만보안 시스템은 각 출입문과 인천항 보안 울타리에 CCTV 카메라를 설치하여 영상보안 시스템을 구축하여 인력과 비용을 크게 줄이며, 감시체제의 효율화를 꽤하고 있다. 따라서 본 논문은 유비쿼터스 환경에서 IP카메라를 활용한 PDA 기반의 영상보안시스템을 설계 및 구현하였다. 본 시스템은 중앙통제실을 벗어난 요원도 PDA를 통하여 어떤 장소, 어떤 시간에서도 실시간 영상모니터링이 가능하기 때문에 기존의 시스템에 비해 비상체계 운영에서 효율을 극대화 할 수 있으며, 인력과 비용에 있어서도 큰 장점을 가지고 있다.

Movie contents requiring multiple shootings in places need much man power and many equipments. It is more serious in the case of multiple simultaneous shootings. In the points of small broadcasting companies, it is more difficult to cope with the situation, but it is also an essential task for the variety of video contents. We propose an one-person movie production scheme based on an IP camera-based live webcasting system which makes multiple shootings in places possible. It consists of three main functions of (1) collecting multiple video streams sent from IP cameras installed in places, (2) properly distributing them to Internet, and (3) receiving and editing them including recording video. By using the proposed scheme, we can be able to remotely utilize a new framework of Single-Person/ Multiple-Camera which beyonds the conventional Single-Person/Single-Camera framework. It becomes possible to take multiple simultaneous shoots in places. We can get an advantage of saving man power and time for producing various movie contents.

The IP cameras have rapidly replaced the analog CCTVs as the cameras have the advantages of not only being able to remotely monitor, but also supplying power through the UTP cable, In this paper, we introduce the protocol architecture of the ONVIF standard which is widely applied to the IP camera and other Internet protocols to support it, and implement the ONVIF Device on a commercial board. Although these functions can be controlled by the Client (PC), several functions such as privacy masks, temperature display of the thermal camera, and ROI (Region of Interest) are implemented through a web viewer on the device. Through the experiment, the functions of ONVIF Profile S and web viewer are verified through SOAP messages exchanged between Device (IP camera) and Client program and streamed images.
