Assuming an iPhone spec camera, that would equal 170mb per minute of 4K30 or 400mb per minute of 4K60. They would record at approximately 2.8mb/s and 6.67mb/s.
An 8TB hard drive with write speed of 160mb/s should have more than enough bandwidth to handle 4K60 recording. This HDD.
How much can you record on an 8TB hard drive?
8TB is 8 million megabytes so dividing it by (400*60) would give us 333.333 hours of footage. That’s about 13.8 days of footage at 4K60
Most security cameras overwrite footage so using an 8TB hard drive would give you almost 2 weeks of footage you can go back on before it’s overwritten. That’s enough time for law enforcement to grab a copy of the footage.
At 4K30, that gives you 32.6 days of footage. So it doesn’t have anything to do with storage. I’m guessing the initial costs just don’t seem to justify the increased resolution for most business owners.
This system costs $630 for four 4K cameras and 2TB storage. Whereas a system with four 720p cameras like this costs $170. That’s almost 4 times the initial cost. Still sucks in cases like these though.
Edit: as someone pointed out this data is true for 1 camera. If you do 8 cameras you can compress the footage to 50% of its original size without major loss of data for more efficient storage. Or compress anyways for double the timespan.
However if all you need is to go back 7 days on footage at 4K30, two 8TB hard drives will provide that with compression on 8 cameras. Regardless, it’s still not astronomically expensive.
