A hovering surveillance device. An electronic imaging device is disposed on a housing having a primary lift element, at least one compressed lighter-than-air gas element, a pitch adjustment element, and, a steering element. The compressed lighter-than-air gas is channeled to the primary lift element and the pitch adjustment element to selectively vary the altitude and angle for the housing such that scene of interest may be imaged. The lighter-than-air gas may be selected from the group of helium, hydrogen, heated air, neon, ammonia, and methane. |
