In this research, we developed video analytic algorithms to detect water-level automatically and a system for proactive alarming using intelligent CCTV cameras. We applied these algorithms and a system to test-beds and verified for practical use. We made camera-selection policies and operation plans to keep the detection accuracy high and to optimize the suitability for the ever-changing weather condition, while the environmental factors such as camera shaking and weather condition can affect to detection accuracy. The estimation result of algorithms showed 90% detection accuracy for all CCTV camera types. For water level detection, NIR camera performed great. NIR camera performed over 95% accuracy in day or night, suitable in natural weather condition such as shaking condition, fog, and low light, needs similar installment skills with common cameras, and spends only 15% high cost. As a result, we practically tested water level detection algorithms and operation system based on intelligent CCTV camera. Furthermore, we expect the positive evidences when it is applied for public use.

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.

This paper relates to the development of CCTV camera posture calibration algorithm that can simultaneously collect traffic information such as traffic volume and speed in the state of view of the CCTV camera set for traffic monitoring. The developed autonomous posture calibration algorithm uses vehicle recognition and tracking techniques to identify the road, and automatically determines the angle of view for the operator's traffic surveillance and traffic information collection. To verify the performance of the proposed algorithm, a CCTV installed on site was used, and the results of the angle of view automatically calculated by the autonomous posture calibration algorithm for the angle of view set for traffic surveillance and traffic information collection were compared.

As the industrial society is developing wars, terrors, and vicious crimes is getting increased. These dangerous factors are caused of casualty and subversiveness of social order. Such vicious crimes lead people to feeling of insecurity. That is why naturally people want to build and inspect strengthened security system. CCTV camera system which can be said as the most popular security system is being installed in public places has large number of floating population. This trend is required to develop the intelligent video security technology and propagate it since the importance of security technology is getting high. This thesis will be described regarding the trend of the intelligent surveillance camera and the scenario.

Under the obligations which is a protection of privacy and a respect for human rights of each person critical is caused by time about surveillance system and CCTV markets which stagnate during that about 911 terror after that securities about importance raising and direction of a ceremony crime prevention are caused by with world grafting of up-to-date IT technique of domestic and changes with the intelligent style surveillance system which leads and quite from the remote place the dead zone this the image which is photographed the Internet leads and with the intelligent style CCTV surveillance systems will be able to control which area at real-time watch and is embodied.

Most of the surveillance systems are based on CCTV, closed circuit Television. A surveillance system for urban transit is also based on CCTV. Urban transit operation corporations have a CCTV system and a lot of cameras to monitor the situation for the passengers, and the important facilities. But this system has some problems that it cannot respond to a state of emergency immediately. In this paper, we describe a configuration of an intelligent surveillance system for urban transit to solve that problems. Our proposed configuration include a camera with some intelligent module, and a processor to integrate various data from not only cameras, but also sensors such as a temperature sensor, a heat sensor, sound sensor and etc. and some other data generator. This system configuration can decide the state of the passengers and the facilities. The surveillance system with this configuration can available with the existing surveillance system without a considerable improvement.

In this paper, an intelligent CCTV was designed and experimentally developed by using an IOT device, Raspberry Pi, and artificial intelligence technology. Object Detection technology was used to detect the number of people on the CCTV screen, and Action Detection technology provided by OpenPose was used to detect emergency situations. The proposed system has a structure of CCTV, server and client. CCTV uses Raspberry Pi and USB camera, server uses Linux, and client uses iPhone. Communication between each subsystem was implemented using the MQTT protocol. The system developed as a prototype could transmit images at 2.7 frames per second and detect emergencies from images at 0.2 frames per second.

Recently, for a smart city, there is a demand for a technology for acquiring traffic information using an intelligent road infrastructure and managing it. In the meantime, various technologies such as loop detectors, ultrasonic detectors, and image detectors have been used to analyze road traffic information but these have difficulty in collecting various informations, such as traffic density and length of a queue required for building a traffic information DB for moving vehicles. Therefore, in this paper, assuming a smart city built on the basis of a camera infrastructure such as intelligent CCTV on the road, a solution for calculating the traffic DB of moving vehicles using Vision Tracking of road CCTV cameras is presented. Simulation and verification of basic performance were conducted and solution can be usefully utilized in related fields as a new intelligent traffic DB calculation solution that reflects the environment of road-mounted CCTV cameras and moving vehicles in a variable smart city road environment. It is expected to be there.
