I have been evaluating this NVR security camera system for 10 days now. While I jumped from the initial cash outlay of $250 to $1000 I have no disillusions that this is nothing like the systems used in commercial applications. Then there is law enforcement equipment that a camera alone cost a few thousand dollars. I think I have a well informed level of expectation of what to expect. I am very glad that I opted to spend a bit more. The network based NVR is the way to go for the ease of camera installation if you want to maintain unobtrusive professional installation.
