Sorry my question is unrelated but since you seem to be very knowledgeable on this I'm wondering if you can answer a couple questions:
a) What kind of hard drive space is required for an 8 camera setup that runs 1080p (e.g. 1TB/day of storage, etc.)
b) Is facial recognition a thing for the home market yet? In terms of being able to be alerted if the person is "recognized" or not, being able to tie people to a profile (e.g. alerted that "Joe" was here), etc. Or would this be more of a software thing (unaffordable for home use)?
