Where can I store an endless archive of video surveillance?

Question

CCTV

It is necessary to save video data on the work of the enterprise from three surveillance cameras. You need to store them ALL the time while the enterprise lives. The option with a multi-disk PC on which the videos will be archived does not seem very reliable to me. If you use RAID, then the amount is simply cosmic. The option of recording the archive on Blu-ray discs is too time-consuming. What else can you think of?

Answer 1

If management is paranoid or schizophrenic, then the solution for just such conditions is Ultrium LTO-8. The next after it is Blu-ray.

Answer 2

If you use RAID, then the amount is simply cosmic.

And what did you want? Storing an infinite amount of information will require an infinite amount of storage, which in turn costs an infinite amount of money.

Answer 3

You won't have an easy option.
Almost certainly your DVR, like all modern DVRs, saves recordings as a proprietary video stream that is looped. Those. the drive begins to fill in a circle when it runs out of space.
Accordingly, someone (you?) will need to regularly export fresh records as files and transfer them somewhere. Or look at what is in terms of automation in this regard, but it is unlikely to be cheap.
Such things are developed for serious offices with a regime and secrets, for the preservation of which they are asked strictly.
