网路摄像机的应用，使得图像监控技术有了一个质的飞跃。首先，网络的综合布线代替了传统的视频模拟布线，实现了真正的三网(视频、音频、数据)合一，网络摄像机即插即用，工程实施简便，系统扩充方便；其次，跨区域远程监控成为可能，特别是利用互联网，图像监控已经没有距离限制，而且图像清晰，稳定可靠；再者，图像的存储、检索十分安全、方便、可异地存储，多机备份存储以及快速非线性查找等。-Network camera applications, image monitoring technology makes a qualitative leap. First of all, the network of integrated wiring instead of the traditional analog video routing, to achieve a true three-network (video, audio, data)-one, network cameras plug and play, the project is simple, convenient system expansion　Secondly, the inter- regional remote monitoring possible, especially the use of the Internet, images are no distance restrictions on surveillance, but the pictures are clear, stable and reliable　Furthermore, image storage, retrieval is very safe, convenient and can be stored in different places, multi-machine backup storage and rapid non-linear such as sexual find.
