“Two monitors The answer to my question is not clear. I need at least 2 cameras and 2 monitors. I do not have a smart phone. If I buy two systems,can I use the 4cameras and assume that the 2 monitors will work on all 4 cameras at the same time in different locations in my home. I would like to monitor from 2 locations in my home. Also I'am told to get a 2 camera system with a model # LW2770 ,I can't find that Mel # anywhere in your system”
