Drones or UAV’s (Unmanned Aerial Vehicles) are aircraft controlled by a pilot from the ground or the increasingly popular autonomously following a pre-programmed mission. While there are many type of drones, the main drones fall into one of three categories; surveillance and reconnaissance, armed and civilian.

Aside from the military, real estate agents, especially those selling high-end homes, use drones to fly over their listed properties and capture aerial footage of the grounds and surroundings. Likewise, professional photographers use them to capture unique photographs that would be hard to get by walking. We also have film and motion picture companies using drones for aerial footage, because drones are quieter and don’t vibrate as much as helicopters.

In agriculture, farmers who have very large operations but not a lot of workers use drones to fly over their acreage and look for crop or irrigation problems, or even to count cattle. In this case, the drones have proven to be a valuable tool for farm surveillance and maintenance.

Finally, the police use drones to track down criminals and even for search and rescue missions. They’re a cost-effective alternative to manned helicopters.

Since drones have cameras, they could easily invade someone’s privacy or be used with malicious intent, such as criminals staking out a home to rob. Additionally, one or two drones in rural areas aren’t likely to cause many safety issues, but imagine if Amazon and other large retailers such as Walmart and Sears used drones for delivery, as Amazon’s CEO Jeff Bezos recently suggested. There could be hundreds of drones flying overhead in your neighborhood. The chances of a drone hitting a person, animal, or building would increase significantly—not to mention the noise of all those motors overhead.
