Is this cmr? Or are there two different 4tb s300 disks?

Well according to one website "Toshiba announces the expansion of the Toshiba S300 Surveillance Hard Disk Drive series. This includes a new S300 series using shingled magnetic recording (SMR) technology for small and medium-sized businesses and the renaming of the conventional magnetic recording (CMR) technology surveillance drives to the S300 Pro series for professional and public sector use." However, the Pro series only seems to offer 6TB, 8TB and 10TB. So I would guess that the 4TB drive shown is SMR. (It is also claimed that the N300 series (NAS) is also CMR.)

how to you download hikvision onto hard drive?

Do you you mean footage or install this in the Nvr orDVR or you mean like an external hard drive

Is this compatible with sansco cctv system ?

It should be, it's only a hard drive at the end of the day, you will need to format it to your device. These surveillance drives are just more robust for constant use.

Does this work with zosi cctv system

I use this hard drive with zosi system and hard drive is good.
