Anyone knows, does QNAP have any home NAS that supports ZFS file system?

Need some advice from you guys
I'm planning to get a NAS for storage and record from IP camera (like CCTV for home).
Start with 2 camera, but maybe in future can expand to 4.

Anyone know for such setup, need to give any special consideration for the NAS processor? Wondering if need to do any video processing or something?

Secondly, is there any way to estimate how much storage space I will need for the CCTV recording? I'm afraid I'll end up with not enough storage for my own use

Finally, any recommendation for IP camera that works well with NAS?

Thanks all

Is HGST drives officially sold in Malaysia?
Can't seem to find them.

I've heard many good things about their Deskstar NAS drives, and I'm thinking of getting them for my new NAS setup.
