I'm having a hard time figuring out how to get proper coverage when dealing with corners.  Even with 2 cameras at the corner pointing their respective direction, isn't there a dead zone where they don't meet?  

I saw the Blink XT and had a thought about hiding them on trees and aiming the cameras toward the house because we have a lot of trees around the house.  I could even use a couple for the driveways to get license plate numbers when they pull in.  But having 5 or 6 of those with all of my other devices, I'm worried about bandwidth usage.  Someone stealing the cameras is another worry.  If they know they are there they could sneak up behind them and steal or disable them.
