Surveillance Camera Licenses and activation

I am looking at NAS WD Diskless: My Cloud EX2 Ultra Network Attached Storage - NAS - WDBVBZ0000NCH-NESN on Amazon. Amazon says Milestone Arcus Surveillance software with unlimited camera licenses comes with the NAS. Is this a special offer? Do I have to activate all cameras when I install the NAS or can the cameras be sequentially activated at later dates (when I buy extra cameras) with no additional license costs. Thank you for the information as I am trying to decide which NAS to purchase.

Hello,

Is this a special offer?

The Free License promo has been available for a while now

Do I have to activate all cameras when I install the NAS or can the cameras be sequentially activated
at later dates (when I buy extra cameras) with no additional license costs.

The licenses are triggered with the camera is added to the instance of Milestone Arcus on the EX2 Ultra.
So, if you add 5 camera’s today, you get 5 camera licenses.
If you add 5 more camera’s while the free license promo is running, you get 5 more licenses.
I’m not aware of any “end of free license promo” date.
