In this paper, the 2.4/5GHz dual band was used to ensure the reliability and stability of the wireless AV surveillance system using the existing 2.4GHz band. The proposed system supports dynamic channel allocation and channel change technology to avoid interference from other signals (Wifi, Bluetooth, etc.), reduces maintenance costs incurred when building wireless CCTV, and can be linked with existing wired CCTV. The service area of the A/V surveillance system used can be expanded.

기존의 야외 주차관리 시스템은 초음파 센서 모듈, 주차 유도 센서, 주차 감지 전용 센서 등의 소형 센서와 장치들을 다수 사용하기 때문에 고비용의 발생과 주차장 관리의 불편함이 초래된다. 이러한 기존 시스템이 요구하는 장치들을 최소화 하고자 CCTV 기반의 소프트웨어 영상처리 기술로 차량의 위치와 주차공간의 유/무를 확인할 수 있는 야외 주차장 관리 시스템을 제시한다. 제시하는 시스템은 MOBILE 기반의 서비스를 제공하기 때문에 사용자에게 편리한 주차장 이용 서비스를 제공하고, CCTV를 기반으로 관리자에 의한 실시간 모니터링으로 주차장 내의 사고 및 긴급 상황을 인지해 사고를 대응할 수 있다.

As the existing face recognition CCTV and home IOT have each individual hardware component, they have a disadvantage that the measured results of their sensors and the CCTV can not be viewed on one screen at a time. In order to overcome the above disadvantages of existing CCTV and home IOT, this paper proposes an integrated platform which constitutes the CCTV and home IOT as one hardware component using Raspberry Pi and shows each result on one screen through Smartphone application. The proposed integrated platform CCTV and home IOT system is a system which can run the application as a Smartphone and check the sensor value measured by Raspberry Pi and the picture taken through the Pi camera. The implemented system measures temperature, humidity, gas, and dust, and implements face recognition technology on a screen shot through a Pi camera, allowing it to be seen at a glance with a Smartphone.

Traffic estimation mainly involves surveying equipment such as automatic vehicle classification, vehicle detection system, toll collection system, and personnel surveys through CCTV (Closed Circuit TeleVision), but this requires a lot of manpower and cost. In this study, we proposed a method of estimating traffic volume using deep learning and stereo CCTV to overcome the limitation of not detecting the entire vehicle in case of single CCTV. COCO (Common Objects in Context) dataset was used to train deep learning models to detect vehicles, and each vehicle was detected in left and right CCTV images in real time. Then, the vehicle that could not be detected from each image was additionally detected by using affine transformation to improve the accuracy of traffic volume. Experiments were conducted separately for the normal road environment and the case of weather conditions with fog. In the normal road environment, vehicle detection improved by 6.75% and 5.92% in left and right images, respectively, than in a single CCTV image. In addition, in the foggy road environment, vehicle detection was improved by 10.79% and 12.88% in the left and right images, respectively.

지금 국내의 CCTV 업계는 DVR 업체를 제외하고는 방향성을 상실하고 있는 것 같이 보여진다. CCTV 시스템은 보안 시스템의 일부를 구성하는 중요한 파트로서 앞으로도 보안산업의 발전과 그 맥락을 같이하는 분야이므로, 전체 보안 시스템 산업의 방향성을 잘 관찰하여 사업계획을 수립해야 한다. 카메라업계의 경우 무엇보다 R&D에 중점을 두고 기술개발에 계속 매진해 나가야 할 것이다. 향후 카메라의 시장 방향은 저조도용 칼라 카메라, 고해상도 및 고 색상재

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.

Due to the development and market expansion of image analysis and recognition technology, video security such as CCTV cameras and digital storage devices, are required for real-time monitoring systems and intelligent video security systems. This includes the development of more advanced technologies. A rotatable PTZ camera, in a CCTV camera system, has a zoom function so you can acquire a precise picture. However it can cause blind spots, and can not monitor two or more moving objects at the same time. This study concerns, the intelligent tracking of multiple moving objects, CCTV systems, and methods of video surveillance. An intelligent video surveillance system is proposed. It can accurately shoot broad areas and track multiple objects at the same time, much more effectively than using one fixed camera for an entire area or two or more PTZ cameras.

CCTV는 다양한 목적을 위해 24시간 영상을 녹화하지만 현재 시스템으로 사각지대 없는 CCTV 시스템은 다수의 카메라를 설치하여만 한다. 최근 360도 CCTV의 등장으로 동시에 사각지대 없는 촬영이 가능하지만 아직은 해상도, 이미지 변환과 같은 기술적인 개선 연구가 지속적으로 보완되어야 하는 상황이다. 본 논문에서는 천정, 바닥, 벽에 부착된 360도 CCTV 촬영된 이미지를 안드로이드 모바일 기기에서 변환할 수 있는 앱을 개발하여 이동중에 촬영영상을 모니터링할 수 있도록 한다.
