Internet Cooperative Surveillance System Design and Implement

Abstract

隨著社會治安日益惡化，人們對保全系統的迫切需求因應而生，然而在現行的保全系統運作模式中，多採由保全公司經營管理或建立警民連線的方式進行，一方面系統建置費用昂貴，另一方面警力支援往往緩不濟急，成效與普及率不彰。有鑑於此，本系統 i-COPS (Internet cooperative surveillance system)，利用網際網路與行動通訊的普及性與便利性，提出一套「多人互助式監控聯防」的新保全模式。本系統運用網路攝影機結合影像辨識系統，於使用者端建立一個主監控畫面，用來判斷是否有人入侵，並透過無線網路技術運用手持式裝置傳送警訊至使用者手中，使用者並可在任何時間、地點連線察看監控情形，除了使用者可自行監控之外，本系統並建立聯防機制，集結好友構成一套組織綿密的互助聯防網路，達到守望相助的目的。基本上目前寬頻網路ADSL已相當普及，加上家家戶戶幾乎都有電腦，只要加購一台低價位網路攝影機搭配使用即可。本系統可直接與現有的電腦、網路與通訊設備結合，且透過成員互助的方式，大大降低了硬體設備投資成本與營運人力耗費，提供了一套「成本低、親和性強、信賴度高」的保全方案。 本系統影像辨識方法採用RGB比對來判斷警戒程度，經測試後證實可行性高，未來若要擴大系統的辨識範圍，只需加入新規則即可，不需重新建構新系統，因此所設計之系統具有很方便的擴充性。

Facing with the high criminal rate, nowadays the demand for a reliable and pervasive security surveillance system to guard our daily life becomes more urgent than ever. General approaches taken today are either authorizing some private security service company to perform security surveillance or establishing an alarm warning system between civilian houses and police offices. However, these approaches usually incur high system establishment/operational cost and heavy human labor. They are difficult to be widely deployed to support a large number of households at a low cost.In this project, we propose and implement a novel economic and high-availability surveillance system, termed, i-COPS (Internet cooperative surveillance system). I-COPS intends to build up a network service platform to allow a group of Internet users to participate surveillance in a cooperative way. Group members can share information of their local sites with each other by defining alarm events, and rules and ways of notifying warning messages. The system is made up by low-cost off-shelve components commercially available today, such as web-cam, PCs, PDA, cellular phone and broadband Internet. This offers a pervasive, cost-effective and highly reliable solution to the security surveillance.
