什么是闭路电视监控系统(Closed-circuit television, CCTV)
闭路电视监控系统（CCTV）是利用摄像机传输信号到特定规格的监视器。尽管某些监控点采用无线传输方式，闭路电视监控还是有别于传统的广播电视系统并不公开传播。闭路电视监控系统常常被用于有安防需求的特定场所，比如银行、娱乐场所、机场或者军事设施。日益增长的闭路电视监控系统应用也带来公共安全和隐私保护的争论。在工业领域（包括工厂、停车场、小区），闭路电视监控器材常常被安装在监控室用于远距离监控部分生产活动或者生产线，或者用于一些不适宜人工监视的区域。闭路电视监控系统可以连续运作或者监控特定的事件。
Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific, limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point wireless links. CCTV is often used for surveillance in areas which need security, such as banks, casinos, and airports or military installations. Increasing use of CCTV in public places has caused debate over public security versus privacy. In industrial plants, CCTV materiel may be used to observe parts of a process that are remote from a control room, or where the environment is not comfortable for humans. CCTV systems may operate continuously or only as required to monitor a particular event.
