【カメラライセンス】Synology Device-License-Pack1 [追加1ライセンス]

Ok, so i buy my own nas, my own hard drives, set it up on my own network, buy my own cameras, then have to pay for a license key to use it?

It takes 1-4 weeks to deliver? Isn't it just a code?

Does this license expire? For example, is this license a 1 year license, then I am required to renew?

How long does it take to receive your license via email after purchase?
