ＩＰ系统概述OVERVIEW： 世邦IP网络安防语音疏导系统是专为城市安防系统中音频广播而设计，用于车站、机场、社区和交通路口等公共场所。该系统提供了所有相关硬件设备（如监控中心用对讲寻呼话筒、监控点网络音频终端、室外防爆防水对讲面板、扩音喇叭等）。因为采用领先的IPAudio?网络音频传输技术，通过普通的计算机网络、光纤（含电信宽带网）实时传送语音数据，具有播放音质好、抗干扰强、双向传输等优点，使语音广播和视频监控完美结合，为安全防范提供更加科学方便的管理。 SPON IP Security Voice PA System is special design for the security system of the city in Public address, For stations, airports, community, traffic intersection and other public facilities. It offered all necessary equipments ( Ex: Paging Mic, Terminal, panel, speaker and so on). As enabled by IPAudio? technology, transmitted the voice data by network, it has the advantages of perfect sound, anti-interference. The Voice Address and Video Monitoring combined perfectly, provide scientific manager for security.
功能特点FEATURES： l 通知广播及背景音乐播放 Inform of broadcast 平常能播放一些政策性的冶安条例规定和通知，可选择全部/局部/单点的播放。空闲时根据需要播放轻松的背景音乐。真正的任意多路广播----每个终端能播放不同内容，音量独立控制； Broadcast some of notifications, play by choose Broadcast/Multicast/Unicast. Play Background music in idle time .Multi-channel broadcasting---- different program played by each terminal, volume control independently.
l 远程语音喊话和指挥 Long-distance command 当发现监控视频中有可疑对象和紧急冶安情况时，总监控中心（局）或者是分监控中心（派出所）均能实现对监控点的紧急语音信号强插，进行疏导人群或指挥现场处理工作，对可疑对象也有语音震慑作用； The headquarters could achieved the Emergency voice signal strong intercalation to the reference point when they found doubtful object and emergency, dispersal of the crowd or command in the local, it also with Deterrent.
l 报警求助、双向语音对讲 Aid to police and intercom 遇有突发情况，群众可就近使用安装在监控点的对讲面板呼叫键，实现求助和报警。支持监控中心与监控点的全双工语音免提通话； The crowd could use the call button on the panel if they meet the emergency, realize the help and alarm. Support the intercom between the Monitoring center and reference point.
l 现场环境监听 Scene monitor 通过监控点的对讲面板(内置咪头)，或外接拾音器，可监听现场声音； Monitor the scene of sound through the panel of the reference point (built-in Mic), or Pickups.
l 双主控系统 Backup controller 服务器和IP网络主控机(嵌入式平台)构成双保险，如一方故障，另一方接管所有终端。是目前唯一提供备份机制的网络广播系统。重大项目首选双主控，以确保稳定无忧。 Double-safety is make up of Serve and IP Main controller (Embedded platform) , one of them take over all the terminal if other was in trouble. The only one public address provide backup. Ensure stability by Backup Main Controller system
l 与视频监控系统无缝整合 Combined with Video Monitor System 通过光端机（有以太网口即可）与IP网络音频终端连接，再与监控中心的系统服务器合成全方位的安防系统，是配套视频监控系统的理想选择。 Audio terminal connected with fiber optic transmitter (need Ethernet interface only), and them compose the security system with Server System in Monitoring center.
