"WD optimized the WD Purple line of hard drives for surveillance applications to improve high-definition video playback, and operate in 24x7 workloads of surveillance environments." "Different from ordinary desktop hard drives designed for eight hours of daily operation, WD Purple drives have the built-in reliability to operate in Hikvision home and small business system installations so critical video footage is available when it is needed most," said Ying Yang, director of testing, Hikvision. "An additional benefit of WD Purple drives is they support up to eight drives and 32 HD cameras so there is the flexibility to expand for future system coverage." "The biggest trend impacting the video surveillance market in recent years has been the transition from analog cameras to network cameras," said Jon Cropley, principal analyst for video surveillance at IHS Technology (NYSE: IHS). "With enhanced resolution, wide dynamic range and day/night functionality in cameras increasing, demand for storage solutions capable of accommodating large volumes of video will also increase."
