Video monitoring with its convenient, intuitive and information content rich and widely used in many occasions. In recent years, with the development of modern science and technology, in particular work bandwidth, puter processing power and storage capacity rapidly increase and various practical video information processing technology, video surveillance technology also appeared a considerable development, video monitoring entered the digital work age, increasingly attention by people and attention. The development of video surveillance system is mainly early analog closedcircuit television monitoring system bined to video monitoring system model of digital video monitor and now the evolution process, and the system of digital video monitor system now according to the technical development and divided into three stages: digital monitor multimedia stage, digital monitor DVR stage and digital monitor work stage. 1, video monitoring system simulations simulate video monitoring system is divided into microprocessorbased video switch control plus PC multimedia management and pcbased realize the switch control of matrix host and system multimedia management two types. Analog closedcircuit television monitoring system is actually the bination of many simulation monitoring equipment, system mainly consists of frontend device and terminal control device and signal transmission medium three parts, including: frontend equipment is mainly a camera, haeundae, decoder, control equipment is mainly a switching matrix, image segmentation device, monitor and control the keyboard, video, etc. Transmission medium including cable, control, etc. As microprocessors, the function, performance of microputers and heighten, mult imedia technology application, the system in functionality, performance, reliability, structure pattern, etc, great changes have happened to the video monitoring system, more convenient, the position of the interface with other technical system tends to regulate, manmachine interface more friendly. But because video monitor and control system in the flow of information form does not change, the video signal is still simulation system, the work structure is mainly a ChanGongNeng, oneway, lumped way of information collection work, so system although has developed 唐 山 學(xué) 院 畢 業(yè) 設(shè) 計(jì) 23 to a high level, has not much potential can dig, its limitations still exist, to meet the higher request, digital is the only way. Simulation monitoring system of main faults are: a, usually only suitable for small range of regional monitor video signal transmission, simulation tools, and is mainly coaxial cable to transmit analog video signal coaxial cable, the distance is not more than the distance twistedpair dump more short, this determines the analog monitor only suitable for single building, small neighborhood and other small range of places. B, the system of expansion ability difference for has already built good system, if want to add new monitory point, often is one change makes all change, new equipment is also hard to add to the original system in. C, unable to form effective alarm linkage, because each part between independent operation, the control protocol is difficult to each other, linkage in the limited scope only. 2 video monitoring system, digital multimedia technology, video with pression technology, work munication technology of digital video surveillance system development, the rapid rise, on the market today there are two types of digital video monitor system type, one is the digital video equipment video monitoring system for the core, another kind is embedded video Web server video monitoring system for the core. Digital video pression technology matures, the puter based on PC universalization, create conditions multimedia monitor. This new video monitoring system of rapid rise, partially replaced with video matrix image segmentation device, video as the core, plementary with other transmitter simulation video monitor mode, its advantage mainly displays in: a, PC multimedia monitor video matrix, the host integrated image segmentation device, many functions of video recor
