    HOW IT WORKS

    Inside a Smart Surveillance Architecture

    In a typical commercial surveillance system, such as the one illustrated here, video footage captured by security cameras in the field is transmitted and recorded by a gateway appliance, which could be either a network video recorder (NVR) or server. 

    This video data can just be stored in the gateway appliance, or optionally (and additionally) be stored in the cloud. Video Management System (VMS) and video analytics software could reside on the gateway appliance and/or the cloud.

      CCTV & Surveillance Storage FAQs

      CCTV and smart video surveillance systems generate continuous video streams that demand storage built for 24/7 operation. Unlike standard desktop hard drives, surveillance-class drives are purpose-built to manage high write workloads, reduce frame loss, and operate reliably in challenging environments—such as outdoor enclosures or industrial installations.

      If you're wondering about the difference between surveillance and desktop HDDs, it comes down to durability and performance. Desktop drives are designed for intermittent use and lighter workloads, while surveillance drives like WD Purple and WD Purple Pro are optimized for constant video recording across multiple streams.

      WD Purple and WD Purple Pro drives offer:

      • Optimized performance for multi-camera CCTV and NVR setups
      • Support for continuous recording (24/7 operation)
      • Resistance to high temperatures and humidity
      • Health monitoring (when used in compatible systems)
