  • 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.

  • 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.

  • This paper introduces the development process of mobile home CCTV that enables remote control and object recognition using unused smartphones and Arduino. Clients can control motors connected to Arduino through button, enable bidirectional voice communication between client-server and receive video from the server in real time. The server sends a PUSH notification to the client when its battery is low. When the server recognizes the charger, the client's remote control allows the server to dock to the charger and charge it. It was confirmed that video and voice delivery between client and server works well without any problems, and that object recognition works smoothly.

  • 소비자원 소비자 위해 정보 동향 분석 보고서에 따르면, 10대 미만과 60대 이상이 겪는 사고 중 가정 내 사고의 비율이 약 70%로 높은 비율을 차지하는 것을 볼 수 있다. 기존의 CCTV는 실시간으로 영상 전송은 가능하지만 영상 속의 상황 분석은 하지 못하며, 이를 위해선 지켜보는 인력이 추가로 필요하다. 따라서 보호자의 비용 부담 없이 24시간 행동 분석을 통해 보호가 필요한 가족 구성원의 사고를 예방할 수 있으며 침입과 같은 범죄를 막을 수 있는 AI CCTV의 필요성을 느껴 제작하였다. 해당 CCTV는 실시간 분석으로 영상 내의 위험을 감지하고 감지 후 관련 사항을 등록된 연락처로 송출해서 보호자에게 위험 상황을 알릴 수 있다. 향후 가정 내의 IOT 기기들과 연결하여 위험 상황 발생 시 직접 위험 상황을 해결할 수 있는 스마트 홈 보안으로 범위를 넓힐 수 있다.

  • In this paper, we proposed the skin color based hand and finger detection technology for the gesture recognition in CCTV surveillance. The aim of this paper is to present the methodology for hand detection and propose the finger detection method. The detected hand and finger can be used to implement the non-contact mouse. This technology can be used to control the home devices such as home-theater and television. Skin color is used to segment the hand region from background and contour is extracted from the segmented hand. Analysis of contour gives us the location of finger tip in the hand. After detecting the location of the fingertip, this system tracks the fingertip by using only R channel alone, and in recognition of hand motions to apply differential image, such as the removal of useless image shows a robust side. We explain about experiment which relates in fingertip tracking and finger gestures recognition, and experiment result shows the accuracy above 96%.

  • The purpose of this study is to identify the needs of the nursery director, teachers, parents, and the general public regarding the use of mandatory CCTV. In other words, we will examine the benefits, problems, and solutions of mandatory CCTV. The subjects of this study included families, private day care centers, private presbytery, kindergartens, teachers, parents and the general public in D metropolitan city. The research tools were modified and supplemented questionnaires appropriately for the study purpose with reference to the previous research. Collected data was analyzed by frequency and F-test using SPSS 21.0 program. The main results of this study are as follows: First, the benefits of mandatory CCTV for daycare centers is that CCTV becomes objective evidence of human rights incidents, identifies violence among children, and can take measures. In addition, mandatory CCTV can also reduce or prevent abuse. Second, major problems concerning the mandatory use of nursery school CCTV include privacy, violation of basic rights, and education. CCTV is a stressful factor that causes teachers to feel embarrassed, uncomfortable, and tense. Third, the main improvement measures for the nursery school CCTV mandate are to prevent unfair staff and complement existing guidelines for CCTV use. Based on the results of the study, we detail the benefits, problems, and solutions for the nursing home CCTV mandatory poli.

  • As smart home network services such as home CCTV, outdoor control of home appliances, home security and disaster prevention services become popular, there appear various affiliated products including smart home gateway and smart speaker. Since those services are generally developed on the vendors' individual hardware and software platforms, it is not much expected for them to interwork well among different architecture and communication methods. In this paper, we propose a new home network service system running on an open source platform to address such issues. We implemented a home network system using OpenWRT-based wireless router(or access point) and Zigbee communication technology. In the proposed system, a wireless router replaces a commercial home gateway and small control units implemented with Arduino control electronic devices and sensors in home. Several service scenarios are also implemented to verify the operability of the proposed system.

  • When user wants to receive a smart safe return service, user sends a service request using a smart device to support GPS location data. After the smart safe return system receives the location of user, it selects the neighboring CCTV cameras based on user's location information, and controls the selected CCTV cameras to take a picture of the user, and to chase the user automatically. This service can be useful when there is a crime-ridden district on the path to return home late at night. Previous systems can't provide the smart safe return service to multiple user simultaneously. In this paper, we propose the smart safe return system which can provide the service to multiple users simultaneously.
