Throughout the world people use various means to protect their valuables. Besides technology we also use animals. In the U.S. (and elsewhere) dogs with their excellent sense of smell and hearing protect us from robberies. When I lived in Indonesia they used peacocks because they had a piercing call if a stranger approached the yard at night.
I guess I have a volunteer watch frog in the potted patio tomato...or perhaps he is just free-loading. The look he is giving me says "What's with all this drenching rain every morning?"
