Never really been sold on NVR's...yet in IP/Megapixel Cameras and Software Solutions Posted January 29, 2007 I am always weary of the "expert" guy that totes his new technology is the latest and greatest. I always ask how many units are in the field and can I call someone who is using your product exclusively. I am not sold easily and always test any new technology extensively before I take it to market. The worst scenario is getting a call that a system is down or improperly functioning the week after it was installed because some "expert" with slick shoes said it was the latest and the greatest. I have seen to many salesman burn people.
