This week, AeroVironment announced that the United States Combating Terrorism Technical Support Office was evaluating the Tether Eye. The drone has regular and infrared cameras. That video can be shared live over an encrypted feed. The tether provides power to the drone, so it can operate almost indefinitely, and the box provides shelter, for when the weather makes flying dangerous. The idea is that multiple Tether Eyes would monitor for suspicious behavior, likely in areas where it doesn’t make sense to put a more permanent camera.
