Octatron sells foldable, backpackable unmanned reconaissance aircraft, throwable cameras, and quick set-up mesh nets.
The drone is 20-30K, lot's cheaper than a helicopter. I predict consumer-range prices (say a tenth of that) in a few years.
I see the LAPD is already using the drones. Fortunately people in LA are used to constant helicopter flyovers so I guess this won't be that big a change.
Yes I feel like I'm living in a Bruce Sterling story.
