n.|wired television;[電視]閉路電視
“Closed circuit television”（縮寫為CCTV）的中文譯名為“閉路電視”，指一種通過有線連接或點對點無線傳輸的視頻監控系統。其核心特征是信號僅在特定設備上傳輸，不向公共頻道開放。以下是詳細解析：
1. 基本定義
與廣播電視不同，閉路電視的信號傳輸範圍受控，僅限授權設備（如監控屏幕、錄像機）接收。這種封閉性使其廣泛應用于安全監控領域。
2. 核心組成
3. 主要應用場景
4. 技術演進
早期系統依賴模拟信號，2000年後數字化普及，支持遠程訪問、人臉識别、行為分析等智能功能。部分系統已整合人工智能算法，實現異常行為自動報警。
5. 争議與隱私考量
盡管能有效降低犯罪率，但密集部署可能引發隱私權争議。歐盟《通用數據保護條例》（GDPR）等法規要求使用方需明确告知監控區域。
當前閉路電視系統正向雲存儲、4K/8K超清、多傳感器融合方向發展，同時邊緣計算技術降低了數據處理延遲。如需了解具體品牌或安裝标準，建議參考行業白皮書或專業安防指南。
閉路電視是指通過電視監控系統進行視覺監控，主要用于安全監控、防範犯罪等領域。以下是對“閉路電視”一詞的詳細解釋：
閉路電視系統的應用越來越廣泛，已經成為許多公共場所和家庭的重要設備。希望本文能夠幫助您更好地理解和應用“閉路電視”一詞。
