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.
