摘要

随着人口的增长，商场、剧院、火车站及大型会展中心等公共场所关于安防系统中对安保的需求也越来越大。而为了降低该类营业性公共场所的营业成本，引进无线视频监控系统可以为使用者大大节省经营成本，并且存档的无线视频便于后续的管理与维护。而一般的无线视频监控系统都是由网络摄像机和PC监控管理软件组成。

本课题研究的是网络摄像机的一种新型监控管理软件的设计，其中网络摄像机由STC89C52单片机结合3G路由器、USB摄像头以及舵机组成，其视频数据通过3G路由器的WiFi功能实时转发，然后编写一款Android客户端视频监控管理软件，安卓手机连接上网络摄像机的WiFi网络后打开该软件就能实时进行远程视频监控，可以通过客户端软件上的按钮移动摄像头左右两个方向的摆动，并可以抓拍远程图片保存在手机里，也可以在Android客户端软件中查看，并对之前抓拍的图片进行管理，为用户提供了一定的便利性。

Abstract

As the population grows , shopping malls , theaters , train stations and large convention centers and other public places on the security needs of the security system is also growing . In order to reduce the operating costs of public places such business , the introduction of wireless monitoring systems can greatly reduce the operating costs for users and to facilitate the subsequent archived online video management and maintenance . And general wireless monitoring systems are monitored by the network camera and PC management software.

This research is a new monitoring and management software is designed to network cameras , network cameras by the STC89C52 microcontroller which combines 3G router , USB camera and steering head , whose video data in real time WIFI 3G router forwarding function , then write an Android client video surveillance management software, Android phones on the network even after you open the camera's WiFi network management software in real-time via WiFi network for remote video surveillance, and can move through the lower button on the camera management software on the client about two direction of the swing , and you can capture images remotely stored in the phone in the Android client monitoring and management software to view, monitor the Android client management software can also capture the image before the image management directly , to provide users with a certain amount of convenience .

Key words： Network camera；Android；SCM；WiFi；Steering engine
