My son is getting a CCTV system linked below and it's says the storage can be expanded with another 4tb hard drive.

7200rpm v 5400rpm is this important for a 16 camera system?

Does the hard drive need to be special hard drive like the Toshiba s300 or standard drive as I have a spare drive he could use?


Will a 3.5" usb caddy be fine as there is a spare usb input ?.

Any reccomendedations/advice welcome.

How much data he wants to keep for review at a later time? You need to work out if your regular HDD will cope with the reads/writes.
I've set a system up recently, where on ~10 4k cameras, with even 7-14d of recording, we had to go to enterprise level drive (Toshiba MG) to ensure data was not going to get screwed up by a bad drive.
Most system use one of the three Western Digital (Purple), Seagate (SkyHawk), Toshiba (S300 or MG)

There is some calculators online to work out with how many cameras and what quality you will get certain amount of data written - then check the TB/year workload to see if regular drive is ok to cope.

Tx for the info will look into this further.

The above system has 16 cameras and will be used in a pub so I'm guessing all the cameras be on at the same time.

Video capture resolution states ‎2160p

16 cameras, running with best compression and highest video quality for this kind of setup seems to be estimating 3TB/day or recording..
Most of systems are clever enough these days to reduce fps or scene quality for 24/7 recording when scenes appear near static (say out of hours) so it would still save some GB, but this one is going to need a fair bit of storage or scaling down on quality where it doesn't matter so much. I would be looking at 8TB+ Toshiba MG for this personally.

The system runs for 3tb hard drive with 4tb expansion , could you take a look at the link to it please to see what you think.

I'll have a chat with my son to see how many camera's he's going to run.

Tx for your help.
