Video security technology is making a rapid shift from legacy tape based systems to digital systems employing hard drive storage. According to J.P. Freeman Co., the estimated worldwide market for video surveillance equipment is $4.5B at the factory level with a compound average growth rate of 18%. Further, when you take out the analog portion of this market and look just at digital systems, the market is growing at more than double this rate or approximately 42% (CAGR). As this transition accelerates, advanced applications have come on the scene providing law enforcement and security professional's new capabilities in fighting crime and keeping people safe.
Digital video security systems now enable sophisticated software capabilities to automatically preview and flag security events in seconds, where manually reviewed images would have taken many days or even months to discover similar information. High resolution image capture is moving the quality of stored video from grainy and marginally useful to crisp and incredibly detailed images used to capture criminals, save lives and improve business practices in a wide variety of industries. At the heart of these capabilities are massive hard drives, enabling the storage of incredible amounts of digital video data while also providing unprecedented fast access and review of recorded video not possible on legacy tape based systems.
Seagate's SV35 Series hard drives implement a unique combination of features to improve performance, power management and reliability for surveillance digital video recorders (SDVRs). And as a distinct product family, the SV35 Series is poised to develop new features and functionality independent of other market segments, increasing its capabilities in meeting the unique needs of video security and surveillance customers in the future. The SV35 Series hard drives have the same top performance characteristics of desktop drives while also offering other features unique to digital video recording. Currently, the surveillance market is relying on hard drives that are not customized for their specific needs.
According to Joseph Freeman, CEO of J.P. Freeman Co., "High performance and high reliability video storage/retrieval capabilities are essential requirements of effective surveillance programs in the post-9/11 security environment. Technology advances toward that end make excellent contributions to improved protection."
"Due to the growing importance of domestic security, the demand for digital video surveillance equipment is increasing and Seagate has the only hard drive built specifically for this market segment," said Brodie Keast, Seagate general manager of Consumer Electronics Storage. "Seagate can leverage its leadership in desktop and consumer applications to build a drive with key features that are a necessity in this space."
Video/Data Performance Tuning
Commercial video recording applications combine intense video streaming requirements with the need to also read and write traditional data structures used to manage video databases and related applications. Optimal performance can only be achieved by tuning the read and write strategies to the type of data being used at any given point in time. Seagate SV35 Series hard drive supports the ATA 7 command set, which provides for tuning the read/write profile to be video or data specific. This means that video read/writes are designed to stream reliably, while data read/writes are optimized for data integrity.
Advanced Power Management Features
Digital video recording systems for surveillance are often designed to include multiple hard drives to store the massive amounts of information collected. This can result in difficult power management challenges both at system start time as well as during operation. Seagate SV35 Series hard drive provides a low start-up current (~2.0A) that enables the design of efficient, low cost power supplies. In addition, the SV35 Series enables real-time power-saving features to allow any drive in the system to spin down into power saving mode when not in active use. This allows for much more efficient system cooling, which in turn can dramatically improve overall system reliability.
The Seagate SV35 Series will begin shipping in April 2006.
