I am looking to budget about $2000-$2500 on a surveillance system for a liquor store. Being a high risk retail environment I need cameras that are very clear. I'm still doing research as to how an IP system would work. At the moment I am only familiar with a dvr system, which is what I might be leaning towards. Preferably a Qvis 8 channel receiver...I was wonder what kind of camera would be suggested for my application (I would need two for outdoor use) and also would like to know on 8-channels how much data can be stored on 1tb of high quality video?
