These drones see in the dark

SAN FRANCISCO – The world's largest drone maker has teamed up with the nation's largest thermal camera company to create ready-to-fly drones that can see in the dark. The drone maker is DJI, a China-based company that currently has about 70% of the world drone market. The camera is by FLIR Systems, a Wilsonville, Ore.-based thermal and infrared imaging company. The collaboration will produce drones that can be used in search-and-rescue, firefighting, security and surveillance. At a news conference Thursday, the companies showed video shot from one of the infrared-capable drones in which several people walking in a pitch black field at night looked like brightly lit light bulbs moving across the rough ground.
