Horrible Software and the cameras die over and over

After a home theft I took the advice of a friend who bought this system and is an avid Mac user and took the plunge - 4 700 series cameras for outside viewing - just plug and play Right? After a year in use I have had nothing but problems - the app has no decided it can find my cameras, display the pop up motion alerts but when I try to view a single or all 4 cameras from the app nothing but a spinning circle - NO VISIBILITY. Add to that I just was on the phone with logitech for an hr to replace my 4th camera - thats right - each one died within months and one was a DOA. Great Concept can work fine for months then failure. Hardwire systems are expensive if not prewired and look terrible if you cant hide wires- but they work flawlessly.
