knob on outside of garage.

We recently did an inspection in a subdivision of newer homes (about 4 years old) in Crystal Lake, IL. Every home in the neighborhood had a small knob protruding from the side of garage. It was about 8-10 feet above the ground. It looked like it could be some type of sensor. Any idea what this would be? Sorry, I didn't get a picture.

Perhaps a daylight sensor to control outdoor lighting?

It's hard to say without a close-up picture.
