Abstract

CCTV Systems have been operated in the variety of serveillance fields of the apartment, transportation, safety, physical security, and so on. And their uses are largely increasing as the CCTV transmission technology has been changed from analog to IP network way. Domestic industry has been working to upgrade from analog CCTV systems to High-Definition(HD) CCTV systems for recent years, which involves a few issues such as mixing with several transmission technologies and duplicated investment in each area because the technological analysis and criteria are specifically not arranged. This paper examines the technical issues of the transmission method between HD analog and HD IP CCTV systems, and induces the criteria of the cost analysis and its weighting factors for HD CCTV reformation. By simulating the cost analysis results of both the HD CCTV systems on apartment environment, this paper proposes the reference for the choice of HD CCTV system reformation.

CCTV 시스템은 공동주택을 비롯하여, 교통, 안전, 물리보안 등 산업분야 전반에 걸쳐 다양한 용도로 운용되고 있으며, 기존 아날로그 시스템에서 IP방식으로 전환되면서 활용도가 급격하게 증가하고 있다. 산업계 현장에서는 최근 수년간 아날로그 CCTV가 고화질(HD) CCTV로 전환되고 있으나, HD 아날로그 방식과 HD IP 방식간 기술적 장단점과 기준이 명확히 제시되지 않아 여러 방식이 혼재되고 중장기적으로 중복투자의 문제를 야기하고 있다. 본 논문에서는 먼저 산업계를 주도하는 HD아날로그 방식과 HD IP 방식에 대해 기술적인 특성 및 이슈를 고찰하고, 각 방식별로 전환시 고려해야 할 비용 분석 기준 및 가중치를 설정하였다. 설정한 분석 기준을 공동주택 환경에 적용하여 시뮬레이션 결과를 구함으로써, 고화질 CCTV 시스템 전환시 선택 기준을 제시하고자 한다.
