Western Digital (WD), the California-based manufacturer of storage solutions, recently launched its latest surveillance hard disk drive (HDD) series for large-scale surveillance systems that require large numbers of drive-bays and cameras.
Known as the WD Purple NV, this purpose-built line of 3.5 inch high-capacity, 4 TB and 6 TB HDD are an advancement over the company's standard WD Purple series, which can handle up to eight bays using its software vibration compensation system.
Beyond eight bays, software vibration systems are not effective. This is where the WD Purple NV becomes useful as it features a hardware vibration compensation system, the company explained while speaking to a&s at secutech 2015 in Taipei.
“
The new series are built to withstand the demands of continuous recording in complex systems, while ensuring minimum power consumption. Its high capacity also enables long video
retention periods for analysis and reference.
”
“Along the line that the standard WD Purple supports up to 32 HD cameras, the WD Purple NV supports up to 64, although depending on the system this number can go higher,” said Patrick Lo, Director of Marketing for Digital Video & Data Center Storage Division in APAC at WD. “The WD Purple NV is targeted at large systems while the standard WD purple is targeted at medium to small or even personal home surveillance systems.”
The company further added that the new drives are equipped with several of its exclusive features, including the Allframe technology that reduces video footage loss with proprietary cache policy management technology to help improve data flow and playback.
