CCTV is adopted in most security systems to record events. Nevertheless, traditional systems can only provide image documents after events take place, but they cannot function as an alarm as events take place.Therefore, related computer visual techniques such as motion detection, Human Gesture Analysis are applied to analyze body movements and mainly focus on analyses as well as recognitions of cirminials' actions at the time, for example, actions such as knives, guns at hand or malign attacks. In terms of criminal cases in Taiwan in recent years, some criminals place explosives in important areas to have criminal conducts. However, based on the existent analytical techniques, there is no relevant regarding placement actions. Therefore, the research proposes a scanning posture and analytical technique of placement, combining with legacy scanning, use characters of the above posture and distance between legacy and people, and apply scoring system to find out the suspicious. As a result, it can efficiently prevent crimes. Cooperating CBRV techiniques and taking suspicious clips from videos can help forensic investigators collect beneficial evidence.
