Hello everybody, I have been reading the forums and the information is great. Please, I need help with a 2-4 camera system. I would greatly appreciate any suggestions/advise. I was thinking about a PC based system because I have USB temperature monitors to hookup. The hardest time I have is the iPhone support. I looked at geovision, NUUVO, ALNET, AVerMedia and its getting a bit confusing. Could anybody recommend a good 2-4 camera system with iphone support?
