So I had a break-in at my home a week ago and now it's time to add some cameras. I was initially looking at some of the Dahua cameras, but that Costco deal looks pretty good. I already own a POE switch and have an available dual quad core Xeon computer to use as my NVR host if my existing VM box won't suffice. I will use dedicated network storage for the content (iscsi or nfs). By the end of this project, by goal is to have 6 outdoor and 3 indoor cameras over the next couple of months. What am I missing?
