RHC: Bosch make a beautiful dual tech motion which is very adjustable,
with a reach of either 20 feet or 35 feet.  I use it when animals
approach 100 lbs, and it is precisely adjustable for the microwave
"reach". However, this is designed for interior environments only, so
not usable for this gentleman's situation

Paradox make an outdoor motion based on their DG75 pet immune motion.
It works to -20 F but runs around $100 wholesale.
