The invention discloses a characteristics matching and tracking based video monitoring apparatus and a method. In the invention, high definition cameras must be installed to cover a certain area. The mutually connected high definition cameras are then uniformly connected to a switch, with the consequence of forming a monitoring network so that videos from the cameras can be transmitted from one to another. When a person enters such an area, an HOG algorithm is adopted to monitor the video streams in real time; the targets monitored under the HOG algorithm are listed in numbers with each moving target provided with an identifier of its own and its location known all the time. The characteristics of the targets in the videos are then extracted and analyzed to decide if these targets behave in normal or not. If their behaviors are normal ones, then these targets are not trouble makers. Otherwise, an alarm control device sends a warning to draw the attention of a security man. At the time, the security man can track and observe the behaviors of the persons from the monitoring images and promptly deal with this, therefore preventing something even worse happening.
