Couple of ideas at your local Costco:
#1 - I go in and cut the power to one of the two light panels; preferring to have the longevity of function in the dead of winter over the brightness of two light arrays. This company has been selling through Costco for years, their stuff is pretty good.

#2 - I have not used but understand these to be some of the best in outdoor motions. Donno if you even need the light unit if all you want is to know they are out there.
My inkling is to go low cost and visual over motions integrated into the hub but YOU are going to have to think through how they move, how long they stay, and how you want to be notified (bothered).
Just putting three of those solar light modules out there would give you a lot of "quick look" visibility without a lot of HA hassle. BUT your neighbors might be bugged by the lights going on/off all night 
Lastly #3 - under the category of..."a dog's gotta go when a dog's gotta go"
