    4K = 3840 x 2160 pixels = 8,294,400 pixels per frame

    Assuming 8 bits of color depth (lowest common depth) = 66,355,200 bits per frame (66MB)

    At 24fps (again, low end as mentioned by another commenter) = 1,592,524,800 bits per second (1.5GB)

    95.5GB per minute of footage per camera, assuming literally no compression.

    95.5GB × 40 = 3.8TB × 3 cameras = 11.4TB

    Raw uncompressed video takes up a LOT of space.

    (Yes I used 1000 instead of 1024 for convenience)





  • I spent two hours last night beating myself over the head with RAM sticks. Got an ewasted server that had the alarm misconfigured, figured I’d upgrade it and put in a valid configuration since it was just off my size. Slapped in some matching size sticks and it wouldn’t boot. It took my embarrassingly long to realize that the speeds werent the same and that the server really cared about the speeds being the same, more than it cared about sizes being the same incidentally.

    I work in IT that should have been the first fuckin thing I checked smh
