Then 119 called the police, and the man also flew the drone back to change the battery, and then continued to take pictures of the whole process of putting out the fire.
Only one minute after the firefighters arrived at the scene, there was only a small fire source left, and then the firefighters extinguished the fire completely, and the man’s drone also landed smoothly.
It is understood that when the drone has 20% battery remaining, it will sound an alarm to remind the user to land quickly. If the battery is too low, the drone will drop directly, and the user can only control the direction and adjust its landing position.
