For civilian drones, hovering above a crowd of people is a big no-no. In fact, this very action has led to fines, arrests, and confiscations of the drones from their owners. This is often the case for events like parades, concerts, and rallies. People just really love flying their drones over everyone to get footage.
While it can be quite a view, it is also dangerous for the people around. If the drone crashes for some reason – either a battery issue or someone throwing something at it (it has happened before), the people near it can get injured. Drones have spinning blades, after all. Not to mention the risk of fire starting or electrocution if it crashes to the ground. In all the angles you look, drones above a crowd of unpredictable people is a security and safety problem.
Australia Drones and Security in Crowded Areas:
Using a drone above a crowded area is one of the many regulations surrounding drones. These regulations help ensure a safer sky for both the drones and the people around them.
For law enforcement however, using a drone above a crowded area may actually help the security in the area. A proposed idea in Victoria, Australia involves the security in concerts, rallies, parades, etc. to start using drones as their eyes in the sky. This gives them a better angle at their area, which can help detect trouble.
A software with the goal of identifying aggressive actions in a crowd was also introduced a few months ago. The software, when paired with a decent camera drone, can help identify potential fights occurring in the crowd. In places where people are packed, tempers can easily flare up and riots can start. The software aims to identify people displaying these warning signs so authorities in the area can respond immediately.
The same method applies in this proposed plan to use drones for security reasons. For one, security can manage a lot larger area by using a drone (or even a fleet) during events. Another, people are more likely not to cause trouble when they are aware that security is watching the crowd.
