北京监控安防监控安装公司是什么呢？

来源：缘通租赁 | 发布日期：2023-11-07 17:27:20 | 浏览次数：次

　　监控设备越来越来普及大众化，有网络监控和局域网监控还有及其简单实用的视频监控，很多地方都有视频监控，比如：停车场、楼道、地下室、公园、公司、酒店、交通公路、学校、医院、公寓小区等。

　　北京监控安防监控安装公司公司主要经营监控安防监控安装，3G视频监控、中维数字监控系统、网络人远程监控摄像安防系。

　　北京监控安防监控是一门被人们日益重视的新兴专业，就发展看，应用普及越来越广，科技含量越来越高。几乎所有高新科技都可促进其发展，尤其是信息时代的来临，更为该专业发展提供契机。但就监控业界而言，系统组成一直没得到明确的划分，这使工程商和用户之间谈到安防监控系统时沟通很不方便。

　　对于安防监控系统，根据系统各部分功能的不同，我们将整个安防监控系统划分为七层——表现层、控制层、处理层、传输层、执行层、支撑层、采集层。当然，由于设备集成化越来越高，对于部分系统而言，某些设备可能会同时以多个层的身份存在于系统中。

　　一. 表现层

　　表现层是我们最直观感受到的，它展现了整个安防监控系统的品质。如监控电视墙、监视器、高音报警喇叭、报警自动驳接电话等等都属于这一层。

　　二. 控制层

　　控制层是整个安防监控系统的核心，它是系统科技水平的最明确体现。通常我们的控制方式有两种——模拟控制和数字控制。模拟控制是早期的控制方式，其控制台通常由控制器或者模拟控制矩阵构成，适用于小型局部安防监控系统，这种控制方式成本较低，故障率较小。但对于中大型安防监控系统而言，这种方式就显得操作复杂且无任何价格优势了，这时我们更为明智的选择应该是数字控制。数字控制是将工控计算机作为监控系统的控制核心，它将复杂的模拟控制操作变为简单的鼠标点击操作，将巨大的模拟控制器堆叠缩小为一个工控计算机，将复杂而数量庞大的控制电缆变为一根串行电话线。它将中远程监控变为事实、为Internet远程监控提供可能。但数字控制也不是那么十全十美，控制主机的价格十分昂贵、模块浪费的情况、系统可能出现全线崩溃的危机、控制较为滞后等等问题仍然存在。

　　三. 处理层

　　处理层或许该称为音视频处理层，它将有传输层送过来的音视频信号加以分配、放大、分割等等处理，有机的将表现层与控制层加以连接。音视频分配器、音视频放大器、视频分割器、音视频切换器等等设备都属于这一层。

　　四. 传输层

　　传输层相当于安防监控系统的血脉。在小型安防监控系统中，我们最常见的传输层设备是视频线、音频线，对于中远程监控系统而言，我们常使用的是射频线、微波，对于远程监控而言，我们通常使用Internet这一廉价载体。值得一提的是，新出现的传输层介质——网线/光纤。大多数人在数字安防监控上存在一个误区，他们认为控制层使用的数字控制的安防监控系统就是数字安防监控系统了，其实不然。纯数字安防监控系统的传输介质一定是网线或光纤。信号从采集层出来时，就已经调制成数字信号了，数字信号在已趋成熟的网络上跑，理论上是无衰减的，这就保证远程监控图像的无损失显示，这是模拟传输无法比拟的。当然，高性能的回报也需要高成本的投入，这是纯数字安防监控系统无法普及最重要的原因之一。

　　五. 执行层

　　执行层是我们控制指令的命令对象，在某些时候，它和我们后面所说的支撑诚、采集层不太好截然分开，我们认为受控对象即为执行层设备。比如：云台、镜头、jie码器、球等等。

　　六. 支撑层

　　顾名思义，支撑层是用于后端设备的支撑，保护和支撑采集层、执行层设备。它包括支.架、防护罩等等辅助设备。

　　七. 采集层

　　采集层是整个安防监控系统品质好坏的关键因素，也是系统成本开销最大的地方。它包括镜头、摄像机、报警传感器等等。

　　八.安防系统不仅仅是一个独立的系统，同时他也是一个整体。

　　1.安防监控系统：以平台为核心，以网络为纽带。　安防监控系统的规模及规划，让人有点生畏，或者说让使用者有点生畏。数量众多的摄像头采集的监控图像、编解码设备、服务器如何配置及管理?靠人力已经不能解决大规模监控系统出现的管理问题了，所以打造一个管理平台的需求就显得非常迫切。一个好的管理平台可以将所有的摄像头、报警点、编解码、后台服务器纳入管理，从而使得整套安防监控系统、安全防护系统能够顺畅运行。以平台为核心管理整个监控系统有一个前提，需要足够的带宽来连接这些设备和服务器，没有网络一切就是空谈。

　　2.网络监控：多家不同的设备，实现互联互通。　由于安防监控系统的历史状况(独立的小规模应用为主)，造成了安防监控设备的生产厂家非常众多，而且各个厂家都有自己的一套编解码和网络传输的做法。但是也是因为这个现状的存在，所以要求大型监控系统平台能够接入多家厂商的设备。一者保护用户原有的投资;二者用户在新系统建设时减少投入提供解决办法。在建的大型监控系统都在这个方面做出了大量的努力，都接入了国内主流厂商的视频编解码设备，并且在用户端基本实现了对设备的透明化
