1.5km for ground NLOS use and 10-20-30km LOS from air to ground wireless video transmitter and receiver long-range PA 1W 2W

Hi, thanks for your watch our video, firstly, let me show you the rotated video of the transmitter and receiver. On the thin box, it is our transmitter, There is one CVBS composite audio and video cable input and RF antenna input on the transmitter. The beside big box with screen and control board is our receiver, There is one RF antenna input and the same type of connector audio and video output on the receiver, one more supporting HDMI output 1080P to the HD screen.

Some clients always ask us what distance do the wireless video transmission system support?

Firstly, let me introduce two concepts, LOS and NLOS, LOS is meaning light of sight, straight visibility between a transmitter and a receiver. There is not any obstacle between devices that could interfere. NLOS is meaning non-light of sight, Straight visibility is obscured (partially or completely) by obstacles, thus making it difficult for the radio signal to pass through.

In order to support long-range wireless video transmission, we can make the power amplifier (PA) in 0.5W, 1W, and 2W. It supports 1.5km NLOS from ground use only for the unmanned ground vehicle (UGV) or security camera, It also supports up to 30km LOS distance from air to the ground for UAV drones.

In this picture, we can see one full set of wireless transmitters and receivers, it is including the transmitter (TX), transmitter antenna, receiver (RX), and receiver antenna.

Here is our simple test video again. The frequency is 585Mhz. It is preset at the factory, by our special configure board, it can modify the frequency within 30Mhz, we also can modify it from 170~860Mhz, according to the clients’ requirement, to avoid interfering with local tv frequency or other wireless devices.

It is hard to choose the best wireless video transmitter and receiver from the hundreds of suppliers, we will show you the in-living test video before you make a decision. In what environment you will use the long-range wireless video transmitter and receiver, please ask us, we will show you.

When you watch our demonstration video, the first thing we would like to show you is the full 360° view of our wireless video transmitter and receiver system. On the thinner box, you can clearly see the transmitter unit. It is equipped with one CVBS composite audio and video input, along with an RF antenna input. This compact transmitter is designed for stable signal broadcasting while keeping the size and weight as light as possible, which is especially important for drone and mobile applications. Next to it, you can see the larger box that comes with a screen and control board. This is our receiver unit. The receiver is designed with an RF antenna input and provides multiple types of outputs. Besides the CVBS audio and video output, it also supports HDMI output, allowing up to 1080P resolution for clear high-definition display on external monitors.

One of the most common questions we receive from clients is: What distance can your wireless video transmission system support? The answer depends largely on the usage environment and the power amplifier configuration. For ground applications in NLOS (Non-Line-of-Sight) conditions, the system supports up to 1.5 km. For air-to-ground communication in LOS (Line-of-Sight) conditions, the system can achieve 10 km, 20 km, or even up to 30 km, depending on the selected PA (Power Amplifier) option, which can be configured at 0.5 W, 1 W, or 2 W. This flexibility allows us to provide tailored solutions for various applications, whether it is unmanned ground vehicles (UGV), security monitoring, or UAV drone long-distance video downlink.

To better understand LOS and NLOS: LOS means there is direct, unobstructed visibility between the transmitter and receiver, allowing the radio signal to travel freely without interference. NLOS means obstacles such as buildings, trees, or terrain are blocking the direct visibility, making signal transmission more difficult. Our system is optimized to provide reliable performance in both conditions, with NLOS use cases focusing mainly on shorter distances such as ground robotics or surveillance cameras, while LOS scenarios like drones enable maximum range.

In the complete set of our wireless transmission system, you will find the transmitter (TX) with its antenna, and the receiver (RX) with its antenna. We carefully match the components to ensure stable performance. In our test demonstration, the frequency was set to 585 MHz, which is the default factory setting. However, by using our specialized configuration board, the frequency can be adjusted within a 30 MHz range. Additionally, we offer a broader customization option, where frequencies can be modified anywhere between 170 MHz and 860 MHz. This ensures compatibility with client requirements and allows avoidance of interference with local television channels or other wireless devices.

Choosing the right wireless video transmitter and receiver is not always easy, as there are hundreds of suppliers in the market. What makes us different is that before you make your final decision, we can provide you with real in-field test videos to prove the performance of our system. By understanding the environment where you plan to use the device, whether it is urban, rural, mountainous, or open-air, we can recommend the most suitable solution. Our goal is to ensure that you get a reliable and stable long-range wireless video transmission system that fits your exact application.
