I didn't think of it that way either, and I agree that it's a good point. I think the difference is that the drone is more of a mass-surveillance device where the individual cameras aren't (quite as much). A good analogue might be a police dash camera versus car-mounted license plate readers. They are similar but meant for very different uses.
