According to the statistics of the national police agency, children are accounted for the high percentage of the reports about damage from the crime of kidnapping. Child protection means all types of services and programs that society or adults can do for children in order to promote their healthy growth and development process. The balance and harmony in surveillance and privacy protection is one of today's sensitive issues. Current CCTV is permitted on the premise of the clear notification, when used in the legal purposes of policing, security, transportation, and etc. In this paper, for the prevention of child-related crime, wide-area surveillance cameras and PTZ cameras with high magnification were used in schools, apartments, and playgrounds. The system tracking and monitoring abnormal face using the AdaBoost algorithm was proposed. In the method for detecting abnormal face by the use of methods to move the center of the whole image, 95.5% of the abnormal facial recognition rate and the average speed of 17 frames of abnormal facial recognition were obtained. It is considered that this system will help prevent crime through the detection and tracking the faces of intelligent offenders who are emerging as a serious social problem.
