Today, SD cards are at 32 gigabytes; in the future, it could be 2 terabytes. The increase in capacity could be a ‘game changer’ for video surveillance.
An article, by James Marcella at SecurityInfoWatch.com, states that, “Memory card technology from the consumer world could rewrite how video surveillance systems work. Today, SD cards are at 32 gigabytes; in the future, they could be 2 terabytes. The increase in capacity could be a ‘game changer’ for video surveillance.”
Marcella writes that the new memory cards will not be any larger, physically, than the existing cards. He continues, “What can 2TB of storage give you? For the consumer market, the Secure Digital Association estimates that 100 high-definition movies could be stored on a single card. In the realm of video surveillance, using highly-efficient H.264 video compression a customer could record 30 images per second of high-quality, 1080p HDTV video for close to 55 days on a single card.”
I ask, “What’s a terabyte?”
Wikipedia answers: “A terabyte (or Tbyte) is a SI-multiple (see prefix tera) of the unit byte for digital information storage and is equal to 1 trillion short scale bytes or 1000 gigabytes. The unit symbol for the terabyte is TB.”
I respond, “Oh.”
Monitoring and storage equipment will both be impacted by the larger capacity memory cards.
