Q: Do you have any video transmitters with 2 video channels for use with 2 cameras?
A: Yes. Each transmitter and receiver unit has two Ethernet ports, allowing you to connect two different IP cameras simultaneously. On the receiver side, you can open two RTSP video streams on the same computer screen at the same time for dual-camera monitoring.
Q: Is it possible to have two-way transfer of data and control commands?
A: Yes. Our wireless link works like an invisible Ethernet cable connecting two IP devices (for example, two computers). You can transfer any data or control commands between them just as if they were on the same local network. This allows two-way communication—for instance, between a drone and a ground control station—for real-time data and command transmission.
Q: I would like to connect my computer’s HDMI output to the transmitter and receive the same HDMI image on the receiver. The distance is about 10 km. Is that possible? We plan to use the system in the Amazon rainforest, where there are many trees. Which system do you recommend?
A: Transmitting wireless video over 10 km in a dense forest like the Amazon is very challenging due to heavy signal obstruction from trees and terrain.
The ideal solution is to add one or more relay points between the transmitter and receiver. Each relay must maintain clear line of sight (LOS) with both sides — for example, by placing it on a drone, signal tower, or high antenna above the canopy. It’s also important to consider earth curvature, which can block signals over long distances.
For this type of environment, we recommend using a wireless video and data transceiver with IP MESH (MANET) function, which supports multi-hop relaying. By adding 2–3 relay nodes, you can effectively extend the communication range and maintain stable video transmission.
Q: What happens if I plug the receiver into the LAN port of an existing router? For example, the router’s local network has a gateway at 10.220.20.1. How do I access the receiver data? I don’t want to connect the receiver’s Ethernet cable directly to the computer.
A: Our system is designed for wireless video and data transmission and does not depend on the existing internet or router. The transmitter and receiver create their own private network with AES128 encryption, independent of your local router. Once the wireless link between the transmitter and receiver is established, you can access and transfer data or video directly between the connected devices — just like two computers communicating on the same LAN — without needing to connect through your router.
Q: Hello, I am a drone manufacturer in the defence sector. We are searching for a video and telemetry connection in the 50–100 km range. What solution can you provide? The ground-station price is not important, but the air unit needs to be as cheap as possible.
A: Please check our quotation sheet for detailed pricing. We offer multiple PA (power amplifier) options — 2W, 5W, and 10W — and all of them can achieve up to 50 km under suitable conditions.
- The higher the PA, the stronger the signal and better the anti-interference capability.
- For clean / low-interference environments, 2W or 5W solutions are typically sufficient.
- For complex electronic environments, we recommend the 10W version to ensure stable long-distance links.
Our system supports both video transmission and control/telemetry links. Because both data types need to be transmitted simultaneously, the air unit and ground unit operate in a peer-to-peer (P2P) architecture. They use different bandwidth allocations, but their hardware cost is the same. If you need, we can also match antennas, amplifiers, and customized frequency bands for your UAV platform.
Q: What is the difference between TX900K and TX900B?
A: Currently, there is almost no difference between the two models.
- TX900K: Frequency range is 1420–1530 MHz
- TX900B: Originally 1420–1468 MHz, now expanded to 1420–1530 MHz
👉 In practice, both models now have the same frequency range and performance.
Q: Can users select the operating frequency?
A: The TX900 system operates on one fixed frequency band per device:
- 800 MHz / 1.4 GHz / 2.4 GHz (only one can be chosen)
- Within the selected band, users cannot manually select specific frequencies, because:
- The system uses automatic frequency selection and frequency hopping
- It automatically chooses the best frequency based on interference and signal conditions
- If users do not use our built-in 2W PA and transmitter, and instead use only our transceiver module, they can configure and select the frequency band themselves.
Q: Can users choose different antennas?
A: Yes, users can select antennas based on their application.
However, the antenna must be compatible with the selected frequency band (800 MHz / 1.4 GHz / 2.4 GHz).
Q: Can the system support 7–8 km transmission for an IP camera on a car?
A: Yes, this distance is achievable under proper conditions:
- The base station (tower) should be installed at a sufficient height
- There should be clear line-of-sight (no obstacles) between transmitter and receiver
Under these conditions, 7–8 km is not a problem.
In fact, in our tests, the same system has achieved transmission distances of up to 27 km.

Q: What factors affect transmission distance?
A:Key factors include:
- Antenna type and gain
- Installation height
- Line-of-sight conditions
- Interference in the environment
- Power output (e.g., 2W PA)
Q: Can I Buy a New Air Unit and Pair It With My Existing Ground Unit?
A: Whether our device can connect to the device you already have depends on your system version number. Please follow these steps to check the version information:
- Log in to the device’s web interface.
- Go to the Debug page.
- Send the following command: AT^DGMR?
- Take a screenshot of the returned information and send it to us. For example: DGMR:”CX6602K_V2.00.00_R07_20250113“
Once we verify the system version, we can confirm whether a newly purchased air unit can be paired and used with your existing ground unit.
