EZwatch Pro has been nothing but a problem to me. I have a 8 camera system that regularly decides to become unable to find the capture boards even though they show up in device manager... I have uninstalled, reinstalled, edited the registry... I have finally ordered a real system. You will find absolutely NO support from EZwatch. They do not respond at all. As they say BUYER BEWARE... Look for my 2 boards and software on ebay as soon as I get around to dumping it.
