I have the 8 camera 720p system, and so far I love it. The cameras are clear, set up was easy (as far as mounting the cameras and running the cable) and today I stuck in a 16gb thumb drive to practice pulling a image off the system, and now I am getting a " System is sniffering packet now" message. Whats this mean? I do not have an external hard drive, I just let the camera record and once the disk is full, I write over top of it.
So far I'm impressed with what I got for the price, I wish the IP address and remote stuff was not as complicated. I like the mobile app for my iPhone, that works pretty neat; however, I notice the push notifications work only half the time
