Micro Drone Scout

A palm-sized quadcopter, quiet enough to fly within earshot of a target without being noticed, streaming a live camera feed back to a handheld controller so an operator can scout a building, a rooftop, or a route before committing to it in person. Its small size lets it slip through gaps a person never could.

Flight time is short and it carries nothing beyond its camera and a small light, so it is a purely reconnaissance tool - useful for eliminating unknowns before a job starts, not for anything during the confrontation itself.
