As we all know, an important reason why UAV enthusiasts are so crazy about it is that it can achieve high-definition aerial photography. As one of the functions of UAV video transmitter, it can transmit video or pictures to your computer, and then you are able to edit them through related software to get great aerial video. However, do you know how UAV video transmitter achieves this feature?

How Does Drone Video Transmitter Work?


The mode of wireless video transmitter is directly related to its load and technical level. Generally, the miniature reconnaissance wireless video transmitter, because of its small size and poor load capacity, we usually do not install real-time map transmission function on it, wireless video transmitter transmits the map from the aircraft. After the wireless video transmitter is recycled, the images taken can be downloaded and viewed. Later, wireless video transmitter solutions mapping technology has developed, and a new technology has emerged, that is, UAV ground controllers can share vision with UAV's reconnaissance system in real time, and see what UAV is seeing, but the pictures are still stored on UAV, and there is no data link to share.


Photos and videos from wireless video transmitter solutions can be obtained or output in the following three forms:


1. Memory card

The original drone video transmission system photos and videos are stored in the root directory of the mini-SD card. The fastest way to get these files is to use a card reader. If the memory card on the drone video transmission system is taken out and put into the reader and inserted into the USB port of the computer, the files can be copied into the computer.


2. Memory buffer

Turn on the power supply, keep the mobile phone, COFDM UAV video and data links and aircraft in the normal online state, click the play button in the shooting interface, at this time COFDM UAV video and data links will display all the photos and videos in the memory buffer. At this point, the right dial wheel of the remote control can be used to turn pages. After selecting the required photos or videos, click the download button at the bottom right. It can save the current photo selected by the drone video transmission system buffer to the mobile phone album or the video to the clip directory.


3. Data line

Video data line is a coaxial cable of drone video transmission system used to transmit video baseband analog signals. Video lines generally have 75 ohms and 50 ohms of impedance, and can be roughly divided into - 3, - 5, - 7, - 9 and other models.

 

What Are Types of Drone Video Transmitters?


In the early days, analog format was adopted in the long-range wireless video transmitter. Its characteristic is that as long as the transmitter and receiver of the drone video transmission system work in a frequency band, they can receive the picture. There are two main types of drone video transmission system: analog and digital. Let's see what are the differences between them.


1. Simulated Transmission

The price is low, and the transmission and reception wireless video transmitter solutions of analog picture on the market is usually less than 1000 yuan. It can receive multiple video signals at the same time. The wireless video transmitter solutions of analog image transmission are equivalent to broadcasting. As long as the frequency of the receiver is the same as that of the transmitter, the video signal can be received, which is convenient for many people to watch.


2. Digital Transmission

Nowadays, the UAV suite developed by manufacturers usually carries special digital wireless video transmitter. Its video transmission mode is through 2.4G or 5.8G digital signal. It is easy to use, usually only need to install a mobile phone as a display on the remote control; the wireless video transmitter quality of high-end products is high, the resolution can reach 720p or even 1080p; the transmission distance of high-end products can reach 2km, which is comparable to the ordinary analog image transmission, high reliability and beautiful integrated design.


What Are Differences of Drone Video Transmitter?


We have learned from the above that there are two channels of digital wireless video transmitter, and what are the differences between them? The difference between 2.4G bridge and 5.8G bridge is not small, the correct understanding is the right choice!


1. Wireless standard

The standard wireless video transmitter rates used are different, such as 802.11b or 802.11G or 802.11GN for 2.4G, and the maximum bandwidth of this WLAN can reach 11Mbps. But we say that 5.8G is divided into two standards 802.11a or 802.11an, and the wireless video transmitter rate is as high as 54Mbps. Generally speaking, the transmission rate of 5.8G wireless bridge is higher than 2.4G.


2. Function

2.4G and 5.8G bridges can be used as wireless transmission devices to transmit video surveillance, but at the same time, 2.4G bridges can also be used as Wi-Fi hotspots, which can be directly received by our computers or some Wi-Fi devices and connected to the Internet as wireless AP, while 5.8G bridges are rarely used as such.


With the above methods, you can transmit the video captured by wireless video transmitter to your own mobile phone or computer for further processing. If you need quality UAV video transmitters, or even advice on video processing, you can ask us for help. We are waiting for you!
