Progress is striding forward. What was previously available only to special services is gradually moving into household use. One of such transferable achievements was quadrocopters, which used to extract information and carry out research and observations only for special purposes, and now they can be easily purchased for their own needs in everyday life or as entertainment.
A quadrocopter is a controlled flying device with or without a built-in camera, which has great functionality in its arsenal, depending on the model and its parameters.
Drones are now a fashionable gimmick for both professional and entertainment purposes. Super opportunities for shooting video from a great height, online video broadcasting on 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, a quadrocopter.

Modern gadgets firmly take their place in human life. Today, there is not a single sphere where a helicopter is tried.
What benefits can it bring:
In the near future, this miracle of technology will absorb other areas of human life. Already, mini drones are performing the function of promoters, circling around office buildings at lunchtime advertising cafes and restaurants offering business lunches.Why not launch them into the service sector: they will perfectly cope with the work of waiters, delivering parcels, even finding missing people or criminals, they will be useful in fire protection activities, they will deliver first aid equipment to hard-to-reach places in case of emergencies, and more.
The more complex the functionality of the device, the more expensive it costs. 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 already be a completely different amount.
The cost of drones, depending on their technical performance, varies 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.
Price is directly dependent on functionality.
The name itself suggests four propellers on the structure, to which the 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, dimensions are also chosen. Quadrocopters can be small, medium and large. For indoor games and entertainment, a small device is enough that flies quickly, has maneuverability and will not disappear from the field of view. For open air launches, medium 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.
Small models are equipped with a primitive 2 megapixel cameras. They will not be able to transmit good quality video, but they will diversify entertainment.
Medium drones come with 10-14 megapixel cameras that are capable of decent image clarity and color reproduction.
When studying camera parameters on a quadcopter, 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.
Most of the control methods for flying gadgets are 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. The devices are synchronized via wi-fi.
These devices do not differ in super indicators of autonomy. A mid-range gadget will stay in the air for about 15-25 minutes without recharging. After that, you need to land and change the battery. More resilient copters can fly for up to 40 minutes. Additional batteries are sometimes attached to large models, thereby increasing the duration of autonomy.
The drone protection is installed separately for the body and propellers. Hull protection consists of two large wheels fixed on different sides; in case of a fall, landing or collision, they reliably protect and cushion even the most severe impacts. A local frame protection is provided for the propellers, which prevents foreign objects from entering the blades and keeps them from destructive contacts.
If it is included in the functions of the quadcopter, it is convenient because it can be pre-programmed before launch. This is the so-called point flight. Very suitable for security activities. "Auto" can be turned on both at launch and during the course at any stage of the flight. The drone will independently adjust speed, altitude and other indicators.
It must necessarily be in the arsenal of the device, otherwise it is easy to lose it irretrievably. Even if the helicopter suddenly disappears from the field of view or its coordinates are not determined, turning on the Home mode will return it to the launch site with an error of plus or minus a meter. When using the copter return in this way, remember that it will fly back at the same altitude that was active when Home was turned on. If high objects are possible on the way, then it is better to preset a certain flight altitude.
If the drone packaging is marked “ready to fly”, then the package 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, a great future is predicted for quadcopters. Maybe they will really replace many professions, but they will still be controlled by a person. Inexpensive models available to a wide range of users now play an entertainment and developmental role. There is nothing strange that drones are interesting not only for children, but also for adults.
