무선 센서 네트워크와 GPS정보를 이용한 스마트 보안 CCTV 시스템 구현

Abstract

Abstract: The conventional object tracking techniques using PTZ camera detects object movements by analyz-ing acquired image. However, this technique requires expensive hardware devices to perform a complex image processing. And it is occasionally hard to detect object movements, if an acquired image is low quality or image acquisition is impossible. In this paper, we proposes a smart security CCTV system applying to wire-less sensor network technique based on IEEE 802.15.4 standard to overcome the problems of conventional ob-ject tracking technique, which enables to track suspicious objects by detecting object movements and GPS da-ta in sensor node. This system enables an efficient control of PTZ camera to observe a wide area, decreasing image processing complexity. Also, wireless sensor network is implemented using mesh networks to increase the efficiency of installing sensor node.
