Is this the best set out for my current needs?

@Perimeter @wittaj and all the others

Thanks guys for the precious tips.

I have been testing the cameras today and ended up with a few questions before my final order.
1) is the varifocal the right choice for the 2 sides of the property? I am wondering if it is better to go with a 180-degree camera in the middle. I have set up the HDW5442T-ZE on a corner a tried to capture the whole side of the house (around 20mt). People are not recognizable when they are 20mt away, I guess I will need to make a choice of identifying from the short or long distance?!?!
2) To fully cover the backyard, is it better to have 2 x HDW5442TM-AS side-by-side or a 180-degree camera?

OK guys, I have been reading the whole post about the new T180, I think I am sold and probably buying 2, one for the backyard and one for the driveway. I have a newbie question. The T5442T-Ze has an identified distance of 5.8 while the T180 7mt. Those distances mean "Value or less" or for a subject let`s say at 2mt the image will not be good?
