LOLOL! Well, for me it's available funds! I've already dropped serious coinage for the nvr, the hard drives, and two cameras. Five more cameras to go! I will not commit to the hell of install until I make sure this whole system is working while it's loaded up. Once I do the install, yeah- it'll only take a day. I have a full analog system in place right now too, so I'm in no particular rush. But I am getting anxious to install the upgrade for sure!
