Large-Scale Video Archiving?

Posted by Cliff on from the now-that's-a-lotta-data dept.

BondHeadGuy asks: "Ok, say you have 1000+ cameras emitting 30 frames/second worth of 640x480 grayscale video...and you have to store it indefinitely. What do you do? This is a real question, believe it or not. 30 frames/s * 300 KB/frame = 9 MB/s per camera. 100:1 video compression brings that down to ~90 KB/s. But 90 KB/s * 1000 cameras = 90 MB/s, or ~8 terabytes/day. Retrieval, though, can be essentially arbitrarily slow. Reliability should be good enough to not be annoying long term. Is there a solution that: has 8 TB/day storage capacity, can handle the 90 MB/s write speed, and lets you save some bucks on the (slow) read side?"

  1. No problem. by Russ+Nelson · · Score: 2, Redundant

    No problem. Just broadcast the video streams into outer space on 1,000 different channels of TV. When you want to fetch that video, just go the appropriate number of light years away from earth and start watching.
