WD Purple Surveillance Storage Product Features Desktop drives vs. surveillance-class storage WD Purple surveillance-class storage has been tested to be compatible in a widerange of security systems. These drives are designed to replace standard desktop drives that were not designed for the harsh 24/7 always-on, high-definition surveillance environment. Desktop drives are built to run for only short intervals and are not engineered to withstand high-temperature fluctuations and equipment vibrations found in a typical surveillance application. Improve performance with AllFrame WD Purple surveillance-class hard drives are equipped with AllFrame technology which works with ATA streaming to reduce frame loss, improve playback and increases the number of drive bays supported. AllFrame reduces video interruptions that commonly occur when desktop hard drives are incorrectly used as storage in security systems. Missed frames and lost footage is a serious problem when an event occurs and surveillance footage needs to be retrieved. WD Purple with AllFrame provides the confidence you should expect when it's time to play back and review critical surveillance footage. Engineered for compatibility WD Purple surveillance hard drives are built for compatibility with industryleading chassis and chip set manufacturers for seamless integration into your new or existing video surveillance system. Check out our compatibility selector to find out what surveillance drive is right for you. Optimized performance for up to 32 HD cameras WD Purple hard drives are optimized to support up to 32 high-definition surveillance cameras, giving you the flexibility to upgrade and expand your security system in the future. Lower power consumption Low power consumption is crucial in high-temperature always-on surveillance environments. With exclusive IntelliSeek™ technology, WD Purple drives calculate the optimum seek speeds which lowers power consumption, noise and vibration that can damage and cause drives to wear out more quickly. When you invest in a premium surveillance-class drive you worry less while enjoying the benefits over a longer period of time. 3-year limited warranty (worldwide) Trust a company with the confidence to stand behind their surveillance storage products with a 3-year limited warranty worldwide.
