1. Obstacle avoidance ability of UAV: When purchasing an aerial photography drone, choose a model with obstacle avoidance function. Aerial photography drones with obstacle avoidance function can provide certain protection, obstacle avoidance is better than no obstacle avoidance, drones with obstacle avoidance function generally have visual positioning function, and can hover stably indoors with poor GPS signal, which greatly reduces the risk of drone collision damage.
2. The signal receiving distance of the UAV is not the only criterion: compared with the maximum distance of the image transmission, more attention should be paid to the stability of the image transmission. Look at the following two points:
Directional antennas can increase the strong transmission distance, and if you don't pay attention to the antenna pointing, it is easy to lose the signal at close range. Aerial photography drones that are only connected with mobile phones have relatively poor image transmission stability. Compared with the remote control specially designed for drones, mobile phones are limited by the limitations of built-in antenna design and transmission power, and their anti-interference ability is weaker.
So it's better to buy a drone with remote control. The remote control distance of the omnidirectional antenna is shorter than that of the directional antenna, but the pointing requirements are lower, and it is more stable at close range.

The signal reception distance of the drone is not the only criterion:
Compared with the maximum distance of the video transmission, the stability of the video transmission should be paid more attention to. Look at the following two points: directional antennas can increase the strong transmission distance, if you don't pay attention to the antenna pointing, it is easy to lose the signal at close range.

The remote control distance of the omnidirectional antenna is shorter than that of the directional antenna, but the pointing requirements are lower, and it is more stable at close range.
4. Whether the camera is stable: Compared with the camera parameters, we should pay more attention to whether the aerial photography drone uses a three-axis gimbal. Camera Parameters:
Resolution, 4K, frame rate, bitrate, and more. Aerial photography is very different from ground photography: in aerial photography, not only the shaking of the drone during flight will cause the camera image to be unstable, but also the high-frequency shake caused by the rotation of the drone's propellers will also cause the picture to have a jello effect.
The three-axis gimbal is equipped with three motors to counteract the shaking of the drone. At present, the most effective solution for the stabilization of the image of aerial photography drones is still the mechanical three-axis gimbal. When we want to buy a drone, we can analyze and compare from the above four points, and basically the use of drones that meet these requirements is very good.
If it's a DJI aircraft, you can ** their app, and the DJI GO app requires iOS or higher and Android or higher. Hantom 3 is perfectly compatible with the DJI Go app for iOS and Android, and the DJI GO app is also compatible with Inspire 1. >>>More
Many of DJI's drones are banned from flying in cities, especially in cities with airports, if there are no local airports to take off and land aircraft, DJI is good, there are more models, according to the use and price, you can choose the Phantom 4 Standard Edition, Professional Edition, Enlightenment, etc. If there is a local airport, and most of the shooting activities are filmed in the city, and the flying area belongs to the no-fly zone, you can not use DJI, you can consider the Haoxiang Typhoon series such as H480, which is a hexacopter, with strong wind resistance, and it is very convenient to have a dedicated remote control, and it will not be interrupted by the flight.

Look higher, farther, from a sky perspective.
First of all, the choice of plant protection drones on the market is diversified, electricity, oil, eight-axis, six-axis, four-axis and so on, but if it is really able to operate the drone or a first-line brand is better. >>>More
