Technology Paper Seagate Briefing: Optimizing Video Surveillance System Reliability and Performance As the world's leading supplier of hard drives, Seagate Technology knows well that all customers and storage applications are not alike. Sometimes the unique requirements of hard drive applications are intuitively obvious. For example, the storage needs of an enterprise database application are clearly different from those of a portable MP3 player stowed in a pocket while jogging. Yet both systems use drives for storage and, though vastly different in size, they share a significant amount of technology in common. Other storage applications are much more subtle in their differences, while still having important unique characteristics that must be acknowledged to ensure storage products deliver optimal value, performance and reliability. Such subtle differences can be found in the growing hard drive market in the video surveillance industry. Here drive use is expanding at a tremendous rate, reflecting the flexibility and advanced performance of hard drive storage over legacy tape-based systems. According to IMS Research, the estimated worldwide market for video surveillance equipment was US$6.6 billion at the factory level in 2006,and is expected to grow to an estimated US$11.6 billion by 2011. Nearly one-third of the estimated revenue would be from hard drivebased surveillance DVRs and NVRs.1 While the adoption of hard drives over tape in video surveillance systems is reaching 100 percent, there is significant room for improvement in system interoperability, with reliability continuing to be an industry-wide challenge. Many customers, having moved to digital surveillance systems and drivebased storage, revel in the improved capacity, performance and flexibility but are disappointed by unexpectedly high failure rates. In addition, they hunger for increased performance to take advantage of the trends towards megapixel recording and intelligent video analytics. Seagate has been working with customers who seek higher levels of performance and reliability, and has identified three key approaches to achieving that goal: ongoing education, improved practices in system design for performance and reliability, and deployment of purpose-built surveillance drives and related controls. 1 Source: J.P.
