The size of the image section can be freely selected. Also the range of motion in which the camera takes a picture or a movie, you can decide for yourself.
Even for a DAU (dumbest assumable user - Say I), the installation is very easy. Connect the receiver to the router and electrical outlet camera into the wall socket and the system looks into the camera by itself. You have to only pay attention to the order.
The camera is a bit more expensive than other systems, but makes much better pictures (and we've tried so many camera).
