Amended to 90 days required storage.
Let's do some math.
4K 60FPS footage - Keep in mind the law says it has to be of good enough quality to 'identify someone', so if it's anything less, they'll claim it doesn't comply, so lets run with that.
H.264 is arguably the most popular encoding method out there for high res video, so we'll go with that.
Let's also assume that this is a small shop, with minimum cameras required by law. We'll say 1 at the door, one at the register, and 2 viewing the general store area from opposite angles.

So, 24 hours of footage from ONE camera, would be around 950GB, which is just short of 1TB. So, due to swap file sizes and cache and blah blah lets just round up to 1TB for ease of use.
So, we have 4 cameras. That's 4TB.
Now we have 90 days required storage.
90*4 = 360TB.. Now, they're going to want redundancy, because equipment failure isn't allowed for under the law, so we'll need to double that and make it a RAID, so we now need 720TB.
Anyone price out a 720TB NAS recently? $100K sound about right?
Now factor in networking costs to support a NAS that size and its constant recording rate.
----
The law says, bare minimum 15FPS... and you can use motion activation... so let's assume the store is open 0800-2000, with half an hour on each end for employees to come/go. That's 13 hours. Cameras will always catch motion because there will be a person (employee) there, so that's 13 hours instead of 24.
13 hours @ 15FPS (retaining 4K resolution) = 128.5GB per day/ per camera - Let's roll that down to 128GB for easy calculation.

128.5GB *4 cameras = 1TB per day.
90 days = 90 TB.
Again, has to be doubled for redundancy, so 180 TB
So, what's a 180TB NAS cost?
