Research Of Home Security Monitoring System

With high-speed economic and social development and the construction of peacesocial security system city, the country is facing rapid development of the field ofvideo monitor and increasingly fierce competition in this industry.Research anddevelop of home security monitoring systems will be of great practical significance.This paper studies the trends of today’s network security monitor technologiesand products, focusing on analysis of user needs and deficiencies of existingproducts. In the extensive literature review, understand the basis of today’s securitymonitor product performance parameters, combined with the trends and user needs inthe field of video monitor, made their understanding and put out solutions. Now mostof the use of video monitor products dedicated video monitoring client,which limitedcross-platform compatibility, and abroad monitoring products with high-precisioncameraare are more expensive and compatible difficult. In the era of seekingmulti-compatible use, the user needs is using in a convenient way, while systemmaintenance and updating is quick and easy. So the video monitor system must bedesigned to support mobile terminal video monitor needs, with highly scalable andgeneric nature, saving the cost of deployment and update.In this design,the embedded video monitoring system is based on ARM. Fullcomparison of the development process for embedded software and hardware relatedparameters, selected mature ARM9processor as the hardware platform, equipped withconvenient Linux2.6.30kernel system as the core monitoring system body. Accordingto the monitoring products’ basic functions and user needs, this system with camera、onboard NIC and other external hardware devices; configured cross-compilerenvironment on the host PC fedora, using embedded C language development andporting of diverse hardware drivers and software features, building the on-board webserver, realized a real-time network video monitor.The main innovation points of this monitoring system is:(1)Based on characteristics of HTML Webpage and MJPEG video stream format,put forward two methods to achieve network monitoring video streaming and playwithout additional plug-in, cross platform compatible terminal conveniently for videosurveillance.(2)Network control script based on embedded Linux shell, realizes the multiplatform terminal remote control monitoring’s hardware and software, combined with HTML JavaScript dynamic Webpage characteristics,provided powerful functions andeasy to debug the script.(3)The system’s architecture design is based on extended open, can becompatible with the existing monitoring system and equipment, greatly reduce thedeployment cost and difficulty, for video monitoring user diversified solutions.By testing and, we can see the security monitor system meets the designrequirements, comparing with similar products on the market has advantages.Support the needs of mobile video monitor terminal, fully utilizing the characteristicsof the network, these openness extension system is the development trend of videomonitor and physical networking.
