Drones, also known as unmanned aerial vehicles (UAVs) or drone aircraft, have revolutionized numerous industries by offering efficient, cost-effective, and versatile aerial solutions. Whether it's capturing stunning aerial drone imagery or assisting in agricultural productivity, drones have proven themselves invaluable tools in both personal and professional settings. As drone technology continues to evolve, understanding the basics—from types of drones to their various applications—has become essential.
DGCA Classification of Drones: From Nano to Large
India's Directorate General of Civil Aviation (DGCA) classifies UAV drones into five weight categories, each designed for specific purposes and regulated accordingly.
Nano Drones (up to 250 grams):
Nano drones are the smallest UAVs and often resemble toy drones or micro racers. Despite their compact size, many nano drones feature cameras that capture high-quality drone images for recreational purposes. Nano drones pose minimal safety risks and are ideal for indoor use. With relaxed regulations—no license or registration required—they are the perfect starting point for beginners.
Micro Drones (250 grams to 2 kilograms):
Micro drones are small, light, and frequently include simple cameras and stabilization systems. For people who wish to take aerial drone photos for semi-professional or personal usage, these drones are ideal. Although a complete commercial license is not required, pilots must register and fly micro drones within visible line of sight. Before users move on to advanced pro drones with cameras, they offer a more comprehensive introduction to drone flying.
Small Drones (2 to 25 kilograms):
The shift to professional UAV drones is represented by this category. Small drones can include cameras that can be adjusted, and some can even have professional-grade thermal cameras for certain applications. They are extensively used in agricultural, real estate photography, cinematography, and infrastructure inspection. Since they fly in more constrained airspace and carry out more complicated missions, small drones need skilled pilots and a commercial drone license.
Medium Drones (25 to 150 kilograms):
Agricultural drones and other medium-sized drones are made for specific business applications. They can carry out operations like long-range surveillance, cargo transportation, and crop spraying since they are equipped with more sophisticated drone components. These UAV drones can lift significant payloads and require certified operators to meet strict safety standards. Their applications extend beyond simple surveillance, offering solutions in challenging environments.
Large Drones (over 150 kilograms):
The largest class of UAV drones includes highly specialized units used for extreme tasks. Large drones are capable of carrying out missions in remote or dangerous areas, where manned operations would be unsafe. These pro drones with cameras are used by industries like defense and heavy logistics, and require the highest level of regulation and safety inspection due to the risks involved.

Sector-Based Applications of UAV Drones
Drones are now indispensable in various industries. Their versatility has expanded applications far beyond just aerial photography. Here’s a breakdown of how drone technology is leveraged in key sectors:
Agriculture Drones:
Pro drones with cameras, like the Krishi Drone, are used to monitor crops and analyze data such as soil health and irrigation needs. These UAV drones can detect crop infestations early, thus preventing large-scale damage. Larger agricultural drones are equipped with sprayers for distributing pesticides or fertilizers, significantly reducing labor costs while improving efficiency.
Cinematography Drones:
Drones with 4K cameras that are portable and foldable have become essential equipment for making movies and TV shows. Drones such as the Elevate model offer unique aerial perspectives, capturing drone images previously achievable only by helicopters. Filmmakers, vloggers, and content producers often use these pro drones that include cameras to get flexible, dramatic pictures.
Defense and Public Safety Drones:
UAV drones are essential for airborne surveillance and intelligence in military operations. During operations, defence drones mounted with infrared cameras and sensors are used to monitor enemy movements and deliver real-time tactical intelligence. Armed drones are also deployed for precision strikes, minimizing the risks to personnel in high-risk areas.
Inspection Drones:
Inspection drones fitted with thermal and high-resolution cameras are used to assess infrastructure such as bridges, power lines, and construction sites. These UAV drones save time and reduce the risks involved in manual inspections, while providing valuable data through drone imagery. Thermal drones, in particular, are used to detect heat leaks in buildings or monitor machinery for overheating issues.
Racing Drones:
FPV (First-Person View) drones are favored by drone racing enthusiasts for their high-speed capabilities. Equipped with onboard cameras that transmit real-time footage to the pilot’s goggles, FPV drones allow for immersive racing experiences. These UAV drones are fast, agile, and capable of performing complex stunts and maneuvers.
Underwater Drones:
While most drones are designed for the sky, underwater drones are engineered for aquatic environments. These specialized UAV drones are used for underwater inspections, marine research, and even recreational diving. Equipped with waterproof cameras and sensors, underwater drones provide real-time footage of submerged environments.
FPV vs. Non-FPV Camera Drones: Which Is Right for You?
FPV, or first-person view, drones give you a pilot’s view during flight. They have built-in cameras that send live video right to the remote controller or to special FPV goggles you wear. This makes you feel like you’re sitting in the drone as it zooms through the air! FPV models are designed to be fast and extremely maneuverable. The tight feedback between camera and controller lets FPV pilots perform aerobatic stunts and swift moves. It’s also perfect for drone racing, allowing you to fly through obstacle-filled courses as if you were aboard the drone yourself. However, the video footage usually isn’t perfectly smooth or ideal for filming cinematic shots.
On the other hand, non-FPV drones prioritize capturing steady, high-quality photos and video footage with stabilization systems and attachable cameras controlled from the transmitter. While some non-FPV drones support FPV modes, they’re built more for creative filming and photography applications. The choice depends on your goals - immersive high-thrill FPV flight or smooth cinematic shooting. FPV performs best chasing racing lines and stunts. Non-FPV drone cameras produce stunning aerial panoramas and filming for projects. Advanced pilots sometimes operate FPV and non-FPV drones for both perspectives!

Conclusion
Drones come in many shapes and sizes to serve a variety of purposes. Small consumer drones with cameras are great for beginners to learn flying and capture scenic footage. Sturdier commercial drones take on heavy lifting like crop dusting and surveillance with their sophisticated features and systems. Racing enthusiasts fly nimble first-person view drones wearing goggles that give an immersive piloting experience. Laws divide drones into size and weight categories to regulate safely as their abilities grow more advanced. From fun weekend flying to professional inspections, drones continue opening more possibilities once limited by human reach and vision. The fast-growing capabilities make drones extremely valuable helpers across so many industries. With safety and responsibility, drones have unlimited potential to keep helping both hobby and work push new heights.
