You're confusing megabits with megabytes. The correct number for your example is 162 GB per day. For reference, a 4K Blu-ray runs about 100 Mbit/s, and requires 1.08 TB for 24 hours of content. (395 TB for a year.) Netflix streams 1080p content at around 6 Mbit/s, and requires 64 GB for 24 hours of content. (24 TB for a year.) Note that both of those examples are 24 or 30 fps. If you turn off the camera when you sleep, multiply by 2/3. If you use hard drives and don't mind 6Mbit/s encoding, it's pretty cheap. Hard drives currently cost about $20/TB, so a year of 24/7 video would be about $500. Multiply by two for redundancy, and you get $1000. If you cut video of yourself sleeping and you massively compress "boring" sections of your life, then it seems plausible one could do it for $200 per year (or less, depending how boring your life is, or how much you care about preserving minutiae :-) ).
