**[Request]** Crazy customer wants to store 10 YEARS of security footage. How much memory would that require?

A facebook group I'm in has a guy who posted this question His customer wants to save 10 years of security camera footage for review after the 10 years. Assuming the customer has 4 (four) 1080p cameras at 15 frames per second, how much memory would be required to make this happen? I'm sure the cost to make this job happen is so astronomically high that it won't be filled, but curiosity got the better of me but I got lost in the math. TIA for the help!
