    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)
