Quadrocopter camera: how to choose the characteristics of

Quadrocopter - a device that takes pictures and video at a distance, is controlled by a special remote control, or applications on your smartphone. Now it is not any technique without the existence of mobile devices.

How to choose the camera quadrocopter

Choosing drone comprises the following steps:

1. First step. Selected popular model, view and compare performance. If you do not navigate the characteristics quadrocopter buying comparable to lottery.
2. In the second step shown in several models and compared with similar characteristics.
3. In the third step check reviews on a specific model and check it for scratches and other defects.

After the purchase you have a legitimate two weeks, during which time the device is returned and the money for it.

Features quadrocopter with camera

Specifications do not reveal the full extent of what the drone. Sometimes the specifications are good, but the quality of the saved. Found even among the expensive models.

Pay attention when buying:

1. Dimensions. The length and height of the product. This indicator is important when buying the online store to present quadrocopter in working conditions.
2. Battery. Battery capacity is measured in milliamps per hour. The figure is higher, the longer the copter flies on a single charge.
3. Radius of action. Diameter, within which will be able to fly copter.
4. transmitter / receiver frequency. It affects the quality of signal reception and transmission.
5. Additional characteristics. GPS-receiver, autopilot.
6. The weight. How malleable wind is design.
7. Resolution of the camera. The higher it is, the greater the video display runs without any loss of quality.

Dimensions

Affect:

1. flight quality. The larger the unit, the less it is suitable for house fly and better equipped to manage the street. Big drone better resist the wind. Professional Model Overall amateur versions, because it is used in harsh environments.
2. shooting quality. The impact of indirect but large models do not require optical stabilization.
3. The duration of the flight. Overall quadrocopter require more battery capacity, consume energy. On such models set more capacious battery.

Battery

Pay attention to the ratio of the battery capacity with the size and weight quadrocopter.

For bounding lifting device requires a powerful engine consumes more electric power. Consequently, the same capacity, which is needed to keep the aircraft is smaller for twenty minutes, the unit would keep larger only 12-15 minutes.

The relationship between the capacity and battery life nonlinear. In addition to size, affects also the work of additional functions such as the autopilot. The greater the capacity, the better.

Radius of action

At what distance flying quadrocopter camera. From amateur models do not need an impressive range, because it is rarely necessary to remove the remote sites. Professional fly sometimes for 2 kilometers. The larger drone takes off scenic landscapes with bird's-eye view, the more powerful a receiver, and the more demanding it to electricity.

Frequency transmitter / receiver

One can not say at what frequency works Mighty quadrocopter, because each type of transmitter and receiver has advantages and disadvantages.

1. 900 Mhz. Plus this frequency - the signal easily passes through the trees, combined with the equipment running at 2,4 Ghz. If broken antenna on the remote control, it is easy to do yourself.
2. 1,2 Ghz. Operating at this frequency drones, overcome long distances. Signal easily passes through solid objects. Antennas can also be done independently.
3. 2,4 Ghz. Worse signal passes through solid objects, but the drone flies at this frequency far. Suitable for professional drones, which remove the most distant objects. Surveying work is carried out in an open field, because there are no obstacles.

Drones are produced with the camera running on 5.8 GHz, but they are rare and are suitable for shooting at short distances.

The distance over which flies the drone is reduced in a wet environment. Also, some frequencies are illegal in a specific country.

Autopilot - Let me ask directions from your smartphone. Drone overcome his own, imprinting on the go everything he sees. The function requires a battery, but easy for the operator.

When buying a camera drone note, if installed on the machine third-party recording devices.

camera Resolution

It affects the detail pictures. At lower resolutions will not work a lot to grasp objects and deploy them on the big screen. Sometimes the quality of shooting at the camera, taking pictures in low resolution, better. To the basic factors influencing the quality of the video include:

1. Optics.
2. The optical stabilization.
3. Matrix size.

comparison

Test selected copter before buying. The shop is possible to check the drone before they purchase. Remove the video and drag on the screen. Evaluate such indicators:

1. The frame rate per second. The video should be no sudden movements, the picture moves smoothly.
2. Color reproduction. Compare chamber together, see how the color in the picture correspond to reality. It happens that the gray asphalt, and video - yellow.

Sound - another critical parameter. Some drones give a good picture, but the producers saved on the voice acting. Better not to buy the device, in which the audio track on the video may be distinct or loud.

Guarantee

If the device that is not satisfied, within 2 weeks, please contact the store. You must return the money for the unit or take it for warranty repair. The warranty will be denied, unless due to defects received after purchase.

Do not attempt to repair the copter, disassemble it, or transfer to a third-party repair service center. This is considered a ground for refusing to return the money or making the device for servicing.
