Whether in the hotel, at home, or in a crowded outdoor fire, we must dial 119 at the earliest opportunity. In the fire, we first saw not the heroic firefighters, but the fire command vehicles carrying the soldiers. Sometimes when we are shopping, the next may be a red fire command vehicle with an emergency rescue call. At this time we will automatically give up a way to let them go to save people.

The fire command vehicle we usually see is red, and it also reads fire's English letter, which means fire; its roof and signal lights are accompanied by a warning tone that keeps flashing, giving people a very thrilling feeling. It will make people unconsciously feel the oppression; there is also a satellite on the hood that accepts a car radio station, and it is necessary to keep the signal flowing. In appearance alone, its other places are no different from ordinary vehicles. But if it comes from its internal structure, it has its own uniqueness.

Its interior is like a small office, although small, but everything has everything. There are satellite phones, for example, when the fire command vehicle enters a place with no signal and can't communicate with the outside world, it can use it to get in touch; with a roof camera, disaster relief is usually a very dangerous environment, not professional Trained videographers simply cannot get into the affected area. Even trained people have certain risks, let alone with machines.

However, the camera on the roof of the car can be used for automatic zooming in the affected area, and does not require personnel to enter the affected area, giving convenience to the camera. But how do you save these shots? Then you need to use a hard disk recorder. It can perfectly save the picture taken by the camera. The most important thing in a fire command vehicle is the UPS, which can be understood as an uninterrupted power supply that can't be separated from any device in the car. Without the power supply, these cannot be opened, and vice versa. These are all related to each other.
