No reason to record oneself sleeping, in the bathroom, or reading a book 99% of the time. Slap some ai or sound/vibration/motion/location logic into the camera

No reason to record oneself sleeping, in the bathroom, or reading a book 99% of the time. Slap some ai or sound/vibration/motion/location logic into the camera and I'll bet there's maybe 8-12 hours a day on average remotely worth recording. Assuming: 78.5yr lifespan 3200mbps/400MBPS@60fps 4k video (Sony fsm72) for 8 hrs of video a day yields: 5.50128 petabytes over 78.5yrs. Or 687.66 8TB drives. At $155/drive that's $106,587.3, or 1,357.8/yr at today's prices. Assuming a 1.666r% price decrease per year, the final years drives will cost approximately $41.8. Taking your 1.24tb as terabits, div 3 and applying the same pattern as above I get 1480.379166TB, 185.05 drives, rounded up, for a cost of 28,830 in today's dollars. Hope my maths right..
