What is the technical term of process when camera sends data to harddrive and it recycles disk space

[HouseUser]

Hello all,

I want to know what the technical term is; when a home security camera system comes with its own 2TB harddrive in which the 2TB harddrive automatically stores all data sent to it by the cameras for the last 2 weeks of recording and then the harddrive frees up disk space automatically.

What is the term to describe the process when the harddrive automatically deletes storage data after 2 weeks (or the oldest day's footage) to automatically free up disk space for the next day's footage?

Is it called the "duty cycle"?

'Overwriting' is often the term that's used in the configuration for that option.
And by the way, just in case of any confusion, it's the system controller / operating system that handles the process, not the drive itself.
