In case Amazons surveillance capabilities werent extensive enough with its Echo, Ring, and Key products, not to mention all the data Amazon routinely collects on its customers, the company recently received a US patent to providesurveillance as a service.

The patent is for anunmanned aerial vehiclethe technical term for a dronethatmay perform a surveillance action at a property of an authorized party and couldimage the property to generate surveillance images. Amazon suggests in its patent, filed June 12, 2015, and granted June 4 of this year, that drone-based surveillance would be superior to traditional video-camera installations that have limited range, are liable to miss things, and can be manipulated or damaged by an intruder.

Drone-based surveillance is a logical next step for Amazon, which has invested heavily in both parts of that equation. The company has been talking about using drones to deliver packages since 2013, at the time, to the great amusement of logistics giant FedEx. These days, Amazons plans are probably looking a lot less funny to its competitors. Amazon consumer chief Jeff Wilke said in early June that the company could start using its Prime Air drone to deliver packages to customers within the next few months, as it pushes to make one-day delivery the new standard on Amazon Prime. Amazons recent patent says surveillance would be asecondary task of such a drone-based system, after package delivery. The company suggests a user may want tosubscribe to a surveillance system to provide surveillance as a service, a riff on the establishedsoftware as a service category.
