Firefighters in Shanghai are to start using drones to help them in their difficult task.

上海消防部门将在执行困难任务的时候使用无人机。

The Shanghai Fire Department will be the first public security force in China to have access to drone support 24 hours a day.

The 1.5-kilogram drones, made of carbon fiber¹, are equipped with an infrared² cameras, allowing them to see in the dark.

They will also be fitted with radar³ systems and communications antenna⁴ to extend monitoring capabilities⁵.

But the truly outstanding feature of these drones is said to be their ability to stay airborne around-the-clock.

Chen Guangwen is responsible for developing the new drone models and explains how these drones are able to stay in the air for so long.

"The conventional drones are powered by gasoline, methanol or lithium batteries, which limit the flying time and can be a trouble. Our drones are powered by a ground facility that supplies electricity."
