IP监控系统节点、视频服务和视频矩阵用于很相似的需求。它们可以在像LAN、企业内部互联网或互联网这样的IP网络中处理多视角输入、数字化、压缩和流数字媒体内容，并将模拟视频系统转换成网络视频系统。用户可以通过网络浏览器或应用软件在网络中的任何一个本地或摄像机计算机上观看实况中电。使用者还可以远程配置和控制。它允许授权的用户在不同的地方同时存取从同一个模拟视频以及安装在系统中的网络摄像机上所获得的图像。这些设备还可以选择的存取视频,并作为独立的单元进行工作。
数字视频传输正快速适应安全和监控的标准要求。图像公司的DSPs使开发人员可以灵活的设计各种数字远程产品。借助DSP的可编程性、处理性能、视频专用外设及支持所有主流多媒体的编译码器，开发人员可以设计出具有定制特性的不同产品以满足不断变化的市场的需求。
IP视频节点/视频服务/视频矩阵元器件主要为TMS320DM64xTM数字媒体处理器

下面对元器件的性能和方框图进行描述：
TI’s video surveillance solutions are primarily based on the high-performance DM64x™ DSP-based digital media processors. The DM64x DSP-based digital media processors have on-chip video ports for easy connection to video devices and are capable of handling both video and audio encode and decode for IP-based video surveillance applications. The single, programmable digital media processor is a cost-effective solution because the need for external PCI or EMAC is eliminated.
