It's been a while since I did a CCTV system for myself so I'm here to freshen up on the technology. My current system I built using linux back in 2008. It's been great but I'm ready for some HD. I helped someone else with a system not too long ago and we did a super cheap cantek HD system which all in all wasn't too bad but the interface left something to be desired. For the money though they were very pleased. This is for myself and I'm willing to put out a little extra money to get a better system but don't want to drop $4000 on a four camera system for my office. Anyone want shoot me some links as to where I should start reading? I'm thinking NVR with IP cameras but I need to do some research on brands, etc. Thanks.
