摘　　要：近年来,基于网络摄像机的视频监控应用得到快速发展,然而传统的视频监控应用必须手动连接配置网络摄像机的服务地址,效率低下。为了解决目前网络视频监控应用不能便捷、高效地自动连接网络摄像机的问题,文中提出了设备自动发现的实现技术,采用基于ONVIF的本地设备发现技术WS-Discovery,使用视窗通信基础WCF4.0和嵌入式万维网服务开发平台gSoap,设计和实现了一个设备发现方法,使得网络视频监控应用系统可以自动发现局域网内的网络摄像机并获取服务地址。实验表明可以有效地发现局域网内的所有网络摄像机。In recent years, video surveillance application based on IP camera has got rapid development;however, it has to connect and configure its service address manually, which is inefficient. In order to solve the problem that the current network video surveillance application can not connect IPCam automatically in a convenient and efficient way ,the implementation technology of discovering device auto- matically is proposed,and Windows Communication Foundation 4.0 and the embedded Web service development platform gSoap are used. A device discovery method is designed and implemented based on WS-Discovery protocol in ONVIF technical specification, and then the network video surveillance system can discover IPCam automatically. The experiment shows it can effectively find all IPCams access to the local area network.
