But only each quadcopter is not networked and works as an independent unit. That is, you will need to coordinate the route between the quadcopters and then compare videos. The best way is to use the systems from UAV Network. Such UAVs are interconnected, the routes are aligned with the position of the other UAV. They also have a large battery capacity, so they can fly long distances and shoot high quality video. This system was developed by graduates of the best aviation university.
