Progress is taking big strides forward. What used to be available only to special services is gradually moving into domestic use. One such breakthrough has been quadcopters, which used to collect information and conduct research and observations only for special purposes, but now they can be easily purchased for your own needs in everyday life or as entertainment.
A quadcopter is a controlled aircraft with or without a built-in camera, which has a lot of functionality in its arsenal, depending on the model and its parameters.
Now drones have become a fashionable feature used for professional and recreational purposes. Super opportunities for shooting video from a great height, online video broadcasting to smartphones or directly to the network, monitoring and control of large areas and not only - all this is a modern invention with an interesting name quadrocopter.

Modern gadgets firmly occupy their place in human life. Today, there is no longer a single area, wherever they tried to use a helicopter.
What benefits can it bring:
In the near future, this miracle of technology will absorb other areas of human life.Already, mini drones are acting as promoters, circling around office buildings at lunchtime advertising cafes and restaurants offering business lunches. Why not launch them into the service industry: they will do an excellent job of serving waiters, delivering packages, even searching for missing people or criminals, they will be useful in fire protection activities, deliver first aid supplies to hard-to-reach places in case of emergencies, and so on.
The more complex the functionality of the device, the more expensive it is. If inexpensive budget models are suitable for children's games, then for video shooting you need to take care of a high-quality built-in camera, and this will be a completely different amount.
The cost of drones, depending on their technical performance, fluctuates in a wide range: from 1,500 rubles to 100,000 rubles. Everything matters here: autonomy of work, flight range, the presence of a certain type of control and communication, the quality of the camera, the material of manufacture.
The price is directly dependent on the functionality.
The name itself suggests four propellers on the structure, to which twin blades are attached.It is on them that maneuverability, speed and hovering in the air depend, therefore, when choosing a gadget, first of all, you should pay attention to:
Depending on the purpose, the dimensions are also selected. Quadcopters can be small, medium and large. For indoor games and entertainment, a small device that flies fast, is agile and stays in sight is all it takes. For outdoor launches, medium-sized models are more suitable, you can mount an action camera on them (if it is not included in the kit), flights will be longer and more varied. Large drones are most often needed for professional use: filming, security and search activities.
Models of small sizes are equipped with primitive 2 megapixel cameras. They will not be able to transmit good quality video, but diversify entertainment.
Medium drones are equipped with 10-14 megapixel cameras, which are capable of decent image clarity and color reproduction.
When studying the parameters of the camera on a quadrocopter, you should consider:
A gadget with a camera has a corresponding cost, so some users prefer to equip the device themselves. Go pro or other action camera options are great for this. In this case, you need to take into account its weight, because it will be an additional load for the drone.
The control methods for flying gadgets are mostly identical: a control panel with buttons and levers that control altitude, maneuvers and modes. For beginners, it is better to learn how to operate the device using a tablet or smartphone and only then switch to the remote control. Touch control is much simpler than lever control. Devices are synchronized via wi-fi.
Super indicators of autonomy, these devices do not differ. The mid-range gadget will last about 15-25 minutes in the air without recharging. After that, you need to land and change the battery. More enduring copters can fly up to 40 minutes. Additional batteries are sometimes attached to large models, thereby increasing the duration of autonomy.
UAV protection is installed separately for the body and propellers. The body protection consists of two large wheels fixed on different sides; in case of a fall, landing or collision, they reliably protect and soften even the toughest blows. For propellers, local frame protection is provided, which prevents foreign objects from getting into the blades and keeps them from destructive contacts.
If it is in the functions of the quadrocopter, it is convenient because it can be pre-programmed before launch. This is the so-called point-to-point flight. Very suitable for security work. "Auto" can be turned on both at startup and during any stage of the flight. The drone will independently adjust the speed, altitude and other indicators.
It must be in the arsenal of the device, otherwise it is easy to lose it forever. Even if the helicopter suddenly disappeared from the field of view or its coordinates are not determined, turning on the “Home” mode will return it to the starting point with an error of plus or minus a meter. When using the return of the copter in this way, you need to remember that it will fly back at the altitude that was active at the time the “Home” was turned on. If high objects are possible on the way, it is better to pre-set a certain flight altitude.
If the drone packaging is marked “ready to fly”, then the kit includes everything you need to fly without additional purchases. In the absence of such a label, most likely, you will need to purchase the necessary add-ons.

Of course, quadrocopters are predicted to have a great future. Maybe they will really replace many professions, but they will still be managed by a person. Inexpensive models available to a wide range of users now play an entertaining and educational role. There is nothing strange that drones are interesting not only for children, but also for adults.
