    World heritage city surveillance system using smart closed circuit television (CCTV) is a system that detects the movement around the monitoring area and then counts the number of tourists who enter and exit the word heritage city. The system has been developed to assist the surveillance system in the world heritage city (WHC) or restricted area through the CCTV camera in detecting the trespassers, when the WHC is closed. This data can be used not only for the surveillance purpose but also for the commercial strategic planning and the security community as well. For example, the number of participants, audience, or visitors who attend the event can be used to plan the upcoming event. In developing the world heritage city surveillance system using smart CCTV, the developers adapted the knowledge about image processing to detect and count the number of people-in and people-out from video data and to security for the system. The system was tested on three set of video data and the results reveal 80-90% accuracy rate. Most of the errors occur when the background area is dark or when people walk in a group but the ability to control critical analysis of communication data to the agency administrator can control the order to increase security for tourists and maintain the condition of the remains a world heritage site.

    This research proposes the concept of security and prevention of road accidence using close circuit television (CCTV) monitoring system in conjunction with the vehicular ad hoc networks (VANET), which is integrated by a 3G or 4G cellular wireless networks. By using the CCTV cameras installed in taxi (car), the image is converted to wireless signal and transmitted via the radio system, in which the communication between cars and taxi call centre can be provided. Moreover, the security of image can be protected by using the signal encryption technique, in which the secret key is available only by authorized person, where finally the required image can be viewed when the crime is occurred. This is the security concept with the privacy violation and protection.

    We propose a new design of a security camera system that uses the dense wavelength division multiplexing wavelength enhancement, whereas increasing in channel capacity and security can be provided. The increasing in number of channel can be obtained by the increasing in wavelength density, while the security is introduced by the specific wavelength filter, which is operated by the central operator. The optical communication wavelength enhancement is reviewed. The advantage is that the proposed system can be implemented and used incorporating with the existed communication link in either wire/wireless system, where the human privacy can be provided, which is discussed in details.
