A drone, or UAV (Unmanned Aerial Vehicle), is a remote-controlled or autonomous flying device used for various purposes like photography, videography, surveillance, and data collection in diverse environments.

Drones are used in fields such as agriculture, construction, search and rescue, filmmaking, surveying, environmental monitoring, wildlife conservation, and infrastructure inspection. They help save time and significantly reduce costs.

Yes, in many countries, you need a license or must register your drone with aviation authorities, especially for commercial use and to ensure safe operations in crowded areas and airspace.

Operators must follow local regulations, which often include flying below a certain altitude, avoiding populated areas, maintaining line-of-sight with the drone at all times, and respecting privacy rights.

Most consumer drones have a flight time of 20 to 30 minutes on a single battery charge, though this can vary based on the model, weight, weather conditions, battery health, and payload capacity.

Some drones are equipped with lights and can legally fly at night, but this typically requires special permissions and strict adherence to local laws and regulations for nighttime operations and safety measures.
