Unmanned Aerial Vehicles for Surveillance: Applications, Limitations, and Emerging Trends

Unmanned aerial vehicles (UAVs), also known as surveillance drones, have proven to be a revolutionary technology in the defense, civilian, and industrial industries. Because of their capacity for real-time monitoring, adaptable installation, and affordable aerial data acquisition, they have established themselves as a vital component of contemporary surveillance systems. Drones provide mobility, scalability, and improved situational awareness, in contrast to conventional static surveillance systems. This article offers a comprehensive analysis of the existing uses of surveillance drones, examines the underlying technical infrastructure of their operations, pinpoints difficulties in technical, legal, and ethical aspects, and outlines upcoming developments like sustainable UAV development, artificial intelligence (AI) integration, swarm intelligence, and 5G/6G connection. The study highlights the need to strike a balance between innovation and responsible implementation, providing insights for academia, industry, and policymakers. *
