Surveillance Goes Digital
Surveillance Storage from Western Digital

Increasing security concerns have caused governments and businesses of all sizes to invest significantly in digital video surveillance systems. Created initially as a means of security for banks in the 1940s, video surveillance systems have evolved to become one of the most popular safety and security systems today.

Thanks to rapid advancement in technology, video surveillance systems have experienced exponential growth since their introduction. In recent years, video surveillance has undergone a shift from analog to digital format and away from primarily tape-based systems.

This transition has resulted in advancements in many complementary technologies. Whether it's software to aid in the recording and analysis of high resolution images, networking systems to more efficiently mirror and archive, or the emergence of technologies such as smart sensors and biometrics, today's surveillance systems demand the best performing and most reliable hard drives and solid state drives (SSD) available.

	Storage designed for digital video surveillance Life in a desktop computer doesn't compare to the extreme environment in today's always-on, capacity-consuming digital video surveillance systems. What's needed is a drive that has been engineered to manage up to 10 simultaneous audio-video streams and welcomes the challenge of an environment that's running 24x7 while offering exceptional dollars-per-gigabyte value. That's why WD has designed a storage lineup of surveillance-based hard drives and SSDs perfect for digital video surveillance and its many unique environments and application sets. High capacity enables higher resolution WD was the first to market with a 2 TB drive designed for surveillance. This ground-breaking capacity point enables surveillance systems with two or more cameras to record high levels of clarity (30 frames per second) at a broad range of resolution settings and still store 30 days or more of video footage. Using high-capacity surveillance drives will become even more important as HD becomes increasingly pervasive. High resolution video provides far greater detail when compared to standard low resolution video.
WD's surveillance drives enable digital video surveillance systems to deliver a comprehensive range of features and capabilities such as high resolution image quality, streaming video from multiple cameras, video archiving with ultra-fast data access and on-demand video playback.
