Surveillance HDD for DVRs, NVRs

by Mark Rowe

Western Digital Corp has added to its WD Purple storage products, including a 18TB surveillance HDD for DVRs, NVRs and analytics appliances, and the 1TB WD Purple SC QD101 microSD card for AI-enabled cameras.

WD Purple drives are optimised for video applications, the manufacturer says, to help reduce frame loss and pixelation, and aid video playback and streaming for 24×7 workloads – from ingest to backup and long-term storage – as the industry uses deep learning and analytics.

From commercial buildings to local government, as the product company says, businesses are adopting AI and deep learning to enable automation and efficiencies. Deep learning algorithms, using data generated by IoT and edge ecosystems, demand higher resolution, and increasing the need for storage capacity in cameras and NVRs.

In its recent report, Video Surveillance and Analytics Intelligence Service, July 2020, market research firm Omdia states that shipments of cameras enabled with deep learning algorithms will continue growing at a five-year (2019-2024) CAGR of 67 percent, and NVRs enabled with deep-learning analytics will grow at 37 percent. Meanwhile, video analytics appliances shipments are expected to grow at 43 percent. A 2020 Western Digital-commissioned survey of North American surveillance installers found that 76 percent of them see video analytics and AI as playing an ever-increasing role in their deployments.

Western Digital says its HDD firmware and data management for its WD Purple drives play a critical role in improving system capabilities as well as managing devices across AI-enabled smart video. Western Digital’s AllFrame technology for WD Purple HDDs delivers caching and streaming management techniques to help prevent data loss and keep up with stream management. Western Digital Device Analytics, software for HDDs, provides monitoring and drive analysis to users, enabling them to detect problems on a drive and provides instructions for remediation before an issue occurs.

18TB HDD

The new WD Purple 18TB HDD is designed for NVRs and video analytics appliances as well as GPU-enabled devices that can deliver real-time and post analytics applications. Offering 28 percent more capacity than the previous generation, the new 18TB drive is for storing video, reference images and metadata at the edge, to support AI. WD Purple drives from 8TB to 18TB feature AllFrame AI that enables recording of up to 64 high-definition cameras, plus an extra 32 streams for deep learning analytics.

WD Purple SC QD101 1TB microSD Card

A WD Purple 1TB microSD card is for AI-enabled cameras, surveillance cameras and edge devices, serving as primary or back-up data storage. It is based on Western Digital’s 96-layer 3D NAND technology, and comes in 1TB, 512GB, 256GB, 128GB, 64GB and 32GB capacities. The WD Purple microSD card is weather resistant, humidity resistant and can withstand temperatures from minus 25 degrees degrees to 85 degrees degrees C. In compatible cameras, the card health monitor provides installers and integrators with the ability to gauge the remaining endurance and preemptively service the card if needed.

The WD Purple 18TB HDD will be available in October; and the WD Purple SC QD101 1TB microSD card in November.

Tim Palmquist, vice president, Americas, at the video management software company Milestone Systems said: “The new WD Purple drives are uniquely designed for the demands of edge and analytics security video appliances that will enable our customers to gain more insights from their visual data. As a leading developer of open and independent IP video surveillance platforms, we value our relationship with Western Digital and are pleased to be working together to provide data storage that can support AI and deep learning, as well as manage multiple streams as video resolutions rise.”

Martin Renkis, general manager Global Cloud Solutions Physical Security, Johnson Controls said: “Leading the charge for the digital transformation of physical security for our customers worldwide, we count on strategic partners such as Western Digital to deliver reliable and high performing storage solutions.

And Eric Spanneut, vice president, Client Computing and Smart Video Business at Western Digital, said: “Working side-by-side with our customers and ecosystem partners gives us unique insights and focus on delivering solutions that are optimized for the most advanced security video workloads. AI is driving the need for more enhanced capabilities in drives to keep up with performance demands, especially as video resolution and the number of incoming streams increase. We are in a unique position as the combination of our software and expanding drive portfolio makes our solutions ideal for deployment into a multitude of smart video applications.”
