The house in question has double patio doors at the back, which
burglars have forced in the past, and are likely to do again.  There
is also a back/kitchen door that is vulnerable. The front of the house
is overlooked by neighbours opposite, so unlikely to be a target, but
I would put the third sensor on the front door to be on the safe side.
It seems logical to have the alarm go off before entry rather than
wait till they've trashed the doors
