Search and Rescue drones

What capabilities should a search and rescue drone have? The ability to adapt to complex environments. Not only in well-lit daytime, search and rescue operations are often carried out at night or in foggy weather, so drones need a sharp eye and professional equipment such as searchlights, thermal imaging, GPS, etc. Superior to traditional human search, search and rescue drones can conduct a large-scale search in emergency situations and quickly locate the target object. Some of them can carry weight to deliver relief supplies when necessary. An absolutely efficient, labor-saving and low-risk solution.
