实时无损的高清图像一直是行业孜孜不倦的追求。近两年源于广电技术的SDI技术在视频监控领域获得重视,各大安防生产厂商都相继推出了HD-SDI系列产品及相关的配套设备,HD-SDI市场正蓬勃发展。近年来,困扰安防企业及用户的“HD-SDI传输距离短(仅有百米左右)”的缺陷随着HD-SDI光端机的研发普及,传输距离已不受限制,使HD-SDI产品可运用在一些需要远距离传输的监控场合。另外,“配套产品不完善”的劣势也随着图
Real-time lossless HD images have always been the industry’s tireless pursuit. SDI technology from radio and television technology in the past two years has gained great attention in the field of video surveillance. Major security manufacturers have successively launched HD-SDI series products and related supporting equipment, and the HD-SDI market is booming. In recent years, the trouble that “HD-SDI transmission distance is short (only about one hundred meters)” that plagues security companies and users is not limited with the popularization of HD-SDI optical transceivers. As a result, HD-SDI products Can be used in a number of monitoring needs long-distance transmission. In addition, “supporting products imperfect ” disadvantage also with the map
