随着现代科学的发展,CCTV监视系统得到了愈来愈广泛地应用。该系统又叫“闭路电视监视系统”。CCTV监视系统可使人们在中心控制室同时观察相距很远的若干个不同场所,并以录相,以备日后查询。目前已能在相当低的照度下进行这些监视。因此,可将CCTV监视系统广泛地用于金融中心、珠宝商店、购物中心、航空港及超级市场等场所。另外,还可用它监护病人以及监视危险环境中的生产过程。 With the development of modern science and technology, CCTV surveillance system has been more and more widely used.
