mso-hansi-font-family: 'times new roman'; mso-bidi-font-family: arial;">传统的电梯监控通常都是使用视频线从电梯直接传送视频图像到监控中心,采用这种监控方式需要重新敷设视频电缆,还要解决电梯内的各种干扰及电缆故障等问题,对工程商来说,无疑是一种负担。因此如果能够利用电梯内的资源,无须布线的视频监控方案无疑是一种很好的选择。</span><span lang="EN-US" style="FONT-FAMILY: arial;"><br/>&nbsp;&nbsp;&nbsp;&nbsp;</span><span lang="EN-US" style="FONT-FAMILY: arial;"><span style="mso-spacerun: yes;">&nbsp; </span></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: arial; mso-hansi-font-family: 'times new roman'; mso-bidi-font-family: arial;">传统的电梯中,每部电梯内都有应急电话,每部电话都与物业的管理中心的程控交换机相连,如果能够直接利用电梯内的应急电话来传输视频信号,无疑是一种很好的选择。在保证应急电话畅通的情况下同时传输视频信号,既利用了现有资源,节约了投资,又缩短了工期,可以快速实现监控。对用户、对工程商来说,都是一种很好的选择。</span><span lang="EN-US" style="FONT-FAMILY: arial;"><br/>&nbsp;&nbsp;&nbsp;&nbsp;</span><span style="FONT-FAMILY: 宋体;

mso-ascii-font-family: arial; mso-hansi-font-family: 'times new roman'; mso-bidi-font-family: arial;">在电梯内传送视频信号可以省掉布线的部分,直接使用网络摄像机或者使用模拟摄像机</span><span lang="EN-US" style="FONT-FAMILY: arial; mso-hansi-font-family: 'times new roman';">+ip</span><span style="FONT-FAMILY: 宋体;

mso-ascii-font-family: arial; mso-hansi-font-family: 'times new roman'; mso-bidi-font-family: arial;">传送到监控中心,由于视频信号在最前端就已经变成了数字信号,因此在传输的过程中可以有效地避免干扰,采用这种传输的方式既可以传输电梯内的监控信号,同时还能承载电梯内的媒体广告信号,使电梯的媒体广告网络化,从而实现远程控制,时时更新,摆脱了传统插卡式电梯广告的桎梏,一举数得。系统示意图如下:</span><span lang="EN-US" style="FONT-FAMILY: arial;
