摘要：随着现代电子技术的发展，视频监控系统也逐步由模拟
走向数字化。视频监控系统是安防领域中的重要组成部分，是所有安全系统中最关键的子系统。系统通过遥控摄像机，直接观察被监视场所的情况，同时可以把被监视场所的情况进行同步录像。另外，视频监控系统还可以与防盗报警系统等其它安全技术防范体系联动运行，
使用户安全防范能力得到整体的提高。
视频监控系统能在人无法直接观察的场合，适时、清晰、真实地反映被监视控制对象的画面。视频监控系统已成为在现代化管理中监控的最为有效的观察工具。视频监控系统是一种全数字化、全网络化的系统，可以同现有的多媒体系统、控制系统和信息系统集成，方便地实现数据和信息的共享在控制中心，只要有一个工作人员操作，就
能够观察多个被控区域，以及远距离区域的监控功能。
视频监控系统由实时控制系统、监视系统及管理信息系统组成。实时控制系统完成实时数据采集处理、存储、反馈的功能；监视系统完成对各个监控点的全天候的监视，能在多操作控制点上切换多路图像；管理信息系统完成各类所需信息的采集、接收、传输、加工、处理，是整个系统的控制核心。

key.The system passes the remote control camera, the direct observation is keep watch on the amenity circumstance, at the same time can is keep watch on the amenity circumstance carries on recording the elephant synchronously.Moreover, the video frequency supervision system can also with guard against theft to report to the police the system etc. other safe techniques guard against the system to move the movement, using a safety to guard against the ability to get the whole exaltation. The video frequency supervision system ability at the situation that person can't observe directly, well timed, portrait, really reflect to be keep watch on appearance of control the object.The video frequency supervision system has become the most valid observation tool supervise and control in modern management.The video frequency supervision system is a kind of total amount word turn, the whole network turn of system, can the together existing multi-media system, the control system and the information systems gather, carrying out the share of the data and information in the control centre expediently, the operation of only a staff member, can observe manies to is control district, and long-distance leave the supervision function of the district.
Video frequency supervision system from solid the hour controls the system, surveillance system and management the information system constitute. The solid hour controls the data for system to complete solid to collect the processing, saving, the function of the feedback,keep watch on the system completes the all-weather surveillance that orders to the each supervision, the ability is operating control point more up cut over many road pictures,Manage the information system completes each kind of to need the information to collect, receive, transmit, process, handle, is the whole control core of system.

第1章 绪 论
1.1 引言
视频监控系统是安全防范技术体系中一个重要的组成部分。目前这种系统的应用在我国发展极快，市场竞争激烈。在本次设计中，视频监控系统主要以下几部分组成：图像信息的采集和预览；对采集画面的简单控制以及存储和回放功能。随着计算机技术的高速发展，整个系统的向着数字化，网络化，集成化的方向发展。本文主要论述一般视频监控系统的工作原理和设计方法，以及简单介绍这种技术的发展趋势。
1.2 视频监控系统的发展历程
视频监控系统的发展大致经历了三个阶段。在九十年代初以前，主要是以模拟设备为主的闭路电视监控系统，称为第一代模拟监控系统。九十年代中期，随着计算机处理能力的提高和视频技术的发展，人们利用计算机的高速数据处理能力进行视频的采集和处理，利用显示器的高分辨率实现图像的多画面显示，从而大大提高了图像质量，这种基于PC机的多媒体主控台系统称为第二代数字化本地视频监控系统。九十年代末，随着网络带宽、计算机处理能力和存储容量的快速提高，以及各种实用视频处理技术的出现，视频监控步入了全数字化的网络时代，称为第三代远程视频监控系统。第三代视频监控系统以网络为依托，以数字视频的压缩、传输、存储和播放为核心，以智

能实用的图像分析为特色，引发了视频监控行业的技术革命，受到了学术界、产业界和使用部门的高度重视。
近年来，随着计算机、网络以及图像处理、传输技术的飞速发展，视频监控制技术也得到飞速发展。由于视频控制系统应用领域广泛，而且发展迅速，目前在国内外市场上，推出了数字控制的模拟视频监控和数字视频监控两类产品。前者技术发展已经非常成熟、性能稳定，并在实际工程应用中得到广泛应用，特别是在大、中型视频监控工程中的应用尤为广泛；后者是新近崛起的以计算机技术及图像视频压缩为核心的新型视频监控系统，该系统解决了模拟系统部分弊端而迅速崛起，但仍需进一步完善和发展。
