Optimized performance for up to 64 cameras
With support for up to 64 surveillance cameras per hard drive, WD Purple gives you the flexibility to upgrade and expand your security system in the future.
Surveillance storage for peace-of-mind
WD Purple Surveillance hard drives are designed for high temperature, always-on, surveillance security systems to help ensure reliability and quality video play back when you need it most.
WD Purple drives are designed to meet the challenges of 24x7 video surveillance recording. These drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple drives, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems. Exclusive WD AllFrame technology helps reduce frame loss and improve overall video playback.
