1-Depends on how many cameras you have, I put one on the left and right, another at the front door. This set up will cover your entire front of the house.2-one on each side, plus one at the back area.3-If you are not handy I would suggest you go with wireless, like Netgear Arlo. Usually people will run wires through attic, this way wires are not exposed but it's a lot of work.
