초록

본 논문에서는 기존 2.4GHz 대역을 이용한 무선 AV 감시시스템의 신뢰성과 안정성을 확보하기 위해서 2.4/5GHz 이중대역을 사용하였다. 제안된 시스템은 타신호(Wifi, Bluetooth 등)로부터 간섭을 회피하기 위해 동적 채널할당 및 채널 변경기술을 지원하고, 무선 CCTV 구축시 발생되는 유지 보수 비용을 절감 시키며 기존 유선 CCTV와 연동 가능해져 CCTV를 이용한 A/V 감시시스템의 서비스 영역을 확대할 수 있다.

In this paper, the 2.4/5GHz dual band was used to ensure the reliability and stability of the wireless AV surveillance system using the existing 2.4GHz band. The proposed system supports dynamic channel allocation and channel change technology to avoid interference from other signals (Wifi, Bluetooth, etc.), reduces maintenance costs incurred when building wireless CCTV, and can be linked with existing wired CCTV. The service area of the A/V surveillance system used can be expanded.
