Desktop drives vs. surveillance-class storage
You wouldnt use a bicycle to transport cargo across the country because its not the right tool for the job. You also shouldnt use a desktop hard drive in your surveillance security system because it wasnt designed for that application.
WD Purple surveillance-class storage has been tested to be compatible in a wide-range 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.
Surveillance storage for peace-of-mind
Whether youre protecting your personal assets and loved ones or monitoring the business you worked hard to build, you can rely on surveillance-class storage built by one of the largest hard drive manufacturers in the world. WD Purple Surveillance Storage is designed for high temperature, always-on, surveillance security systems to ensure reliability and quality video play back when you need it most. Experience the security of knowing youre using a surveillance–class drive designed by a leader in the hard drive industry.
