I purchased this and all of my cameras off of Andy. Extremely nice and helpful guy! This is all new to me and have some very obvious questions. Is there built in memory or must you purchase extra HDD? I see a max size of 10TB x2 port max. Looking at buying these in 10TB:

Yes you need to install your own HDD in the real NVRs LOL as they want you to decide the quality and storage needed for your situation. Ones from Costco and what not come with them but are usually low storage and lesser quality HDDs.

As long as the unit is capable of accepting the HDD, nothing wrong with putting in more storage than you calculate.
