This Small Business Innovation Research (SBIR) Phase II project will develop a digital video surveillance system prototype. Over the past few years, video surveillance systems have been moving from analog to digital. The success of a digital video surveillance system depends on three key enabling technologies: compression, search and retrieval and network transmission. Existing commercial systems generally use standard video compression techniques, which often result in higher memory and bandwidth requirements and jerky object motion. In current video search and retrieval, the existing systems offer only search-by-time and no search-by-content. In network transmission, today's systems use relatively simple techniques that tend to make remote monitoring slow and sluggish. The company is using a highly efficient compression algorithm that exploits the special characteristics of surveillance video and is based on a segmentation technique. This technique, when applied to video search and retrieval, leads to search-by-content, which is more efficient and effective in practical applications. Finally the proposed system will employ fast network transport protocols and scalability techniques to make remote monitoring faster, uninterrupted by network traffic surges, and to allow display on a range of user devices.This digital video surveillance system can be used to maintain the security of banks, airports, government buildings, corporate sites, homes, and small businesses. It can also be used to monitor the performance and operating conditions of machines and equipment.

这个小型企业创新研究（SBIR）第二阶段项目将开发一个数字视频监控系统原型。 在过去的几年里，视频监控系统已经从模拟转向数字。 数字视频监控系统的成功取决于三个关键技术：压缩、搜索和检索以及网络传输。 现有的商业系统通常使用标准的视频压缩技术，这通常导致更高的存储器和带宽要求以及不稳定的对象运动。 在当前的视频搜索和检索中，现有的系统只提供按时间的搜索，而没有提供按内容的搜索。 在网络传输中，今天的系统使用相对简单的技术，往往使远程监控缓慢和迟缓。 该公司正在使用一种高效的压缩算法，该算法利用了监控视频的特殊特性，并基于分段技术。 该技术应用于视频搜索和检索时，可以实现按内容搜索，在实际应用中更加高效和有效。 最后，拟议的系统将采用快速网络传输协议和可扩展技术，使远程监控更快，不受网络流量激增的影响，并允许在一系列用户设备上显示。该数字视频监控系统可用于维护银行、机场、政府大楼、企业场所、家庭和小型企业的安全。 它还可用于监控机器和设备的性能和运行状况。
