A few years ago my dad had a motion sensor/ultra sonic noise generator in the garden for cats. It never worked and after a few months water had leaked into the box making it audible to humans!
Then he tried a ultra sonic noise maker with our dog (she's still here) so that she would stop barking in the middle of the night - Ruby, our dog, ended up shooting out of the back door and being scared to death by the thing (a few months later I took an axe to it )
I think the best method is to get friendly with your local cats and dogs and talk to them I managed to sort our dog out from barking by understanding her psychology - she hated being locked up in a kitchen - I left the door (kitchen to hall) open at night and she stopped barking altogether - no need for gadgets and water pistols!
