Lifeguards in beaches of Rio de Janeiro are using drones with life preservers for faster rescues. The use of the unmanned aerial vehicle prevents people from drowning at the Brazilian capital's crowded beaches.

The drone's camera can broadcast the view of the beach and send the exact location of a person in danger or drowning while a small raft is dropped to serve as a flotation device. The possible victim can stay afloat in the water until lifeguards arrive to make the rescue, per EFE via FOX News.

"The small, unmanned aircraft will allow paramedics working on the beach as lifeguards to spot possible victims beyond the breaking waves," Lt. Col. Fernando Santos, commander of the Copacabana Maritime Association said. Drones are being used in Rio de Janeiro's crowded beaches in Copacabana and Ipanema.

The summer season in the Southern Hemisphere began last week and lifesaving operations like the use of drones are important until April. The small aircraft is operated by a pilot, who passed a 240-hour training course.

"They're taught disciplines like data transmission, equipment recovery and flight security among others. The course is based on three basic points: Safety, equipment maintenance and training," Lt. Col. Rodrigo Bastos, Head of the Fire Department's Unmanned Aircraft Coordination Unit said.

According to Aquatics International, the drones used by the authorities are called, "Ryptide," made by Bill Piedra and a team of computer science students earlier in the year. The technology is described as a life-saving accessory that allows a DJI Phantom drone to drop a self-inflating life preserver to a person in danger in mere seconds.

The first version of the "Ryptide" was made available to the public last July 1 for $199.99 while it can reach from $499 to $1,000 or more depending on the type of the drone. Piedra is the CEO of Flying Robots that manufactures the technology.

His drones will be used in the 2016 Summer Olympics to monitor the beaches of Rio, where about a million visitors are expected daily. Piedra and his team are also working on adding more features including an infrared camera that can detect a person's body heat. They are also developing a new and bigger version of "Riptyde" that can carry four preservers while also discussing the possibility of using the device in water parks, wave pools, boat rescue and floods.

"One is useful, but more than one has more value. You might miss on the first shot and frequently, especially in a riptide, there is more than one person. The diversity of applications is bigger than we ever really thought," Piedra said.
