CNNMoney's Matt McFarland takes a look at Sunflower Labs, a startup headquartered in Silicon Valley and Zurich that has announced a new security system that detects and investigates possible threats using a drone.

The drone, which streams video to the user's smartphone, detects motion, vibration, and sound using a handful of in-ground smart lights that "watch" over the house.
