Description
WD Purple’s exclusive firmware upgrades work with ATA streaming to reduce error pixilation and video interruptions that occur when desktop hard drives are incorrectly used as storage in security systems. WD Purple Surveillance Storage is built for 24/7, always-on, high-definition surveillance security systems that use up to eight hard drives and up to 32 cameras. Choose a drive that is designed and engineered for home and business surveillance systems and enjoy the peace-of-mind you can only get from a surveillance-class hard drive.
