Long-Range Wireless Video and Data Links from China
VcanHK supplies wireless video transmission and data communication solutions for customers developing drones, robotics, remote monitoring systems, industrial equipment, and embedded communication products.
We work with a range of wireless technologies, including COFDM video transmission, OFDM radio links, bidirectional video and telemetry systems, and customized wireless communication modules. Our goal is to help customers identify suitable transmitter and receiver configurations based on their transmission distance, operating frequency, video interface, data requirements, and project budget.
For detailed product specifications and available models, visit our partner product website, iVcan.com.
1. Long-Range Wireless Video Transmitters and Receivers
Wireless video transmitters and receivers transfer live video from a remote camera to a receiving station without requiring a direct wired connection between the two locations.
Depending on the model, available configurations may support HDMI, CVBS, SDI, Ethernet, or other video and data interfaces. Transmitter power, receiver sensitivity, antenna selection, and operating frequency all affect the achievable transmission range.
Typical applications include:
Long-range aerial video transmission
Remote camera monitoring
Ground robots and unmanned vehicles
Industrial inspection systems
Wireless video links between mobile platforms and control stations

2. COFDM Wireless Video Transmission Systems
COFDM is widely used in digital wireless video systems where multipath propagation and changing radio conditions need to be considered.
A COFDM system typically consists of a video transmitter and a compatible receiver. Depending on the model, it may support HDMI, CVBS, SDI, or other inputs and outputs, with different RF frequency ranges and output power options.
COFDM systems can be considered for:
Long-range wireless video links
Mobile video transmission
Remote monitoring and inspection
Applications with reflected signals or partial obstructions
Compact embedded wireless video equipment
Actual performance depends on the radio environment, antenna placement, bandwidth, transmission power, receiver sensitivity, and other system parameters. Non-line-of-sight operation is not guaranteed in every environment.

3. Bidirectional Video and Data Communication
Some projects require more than a one-way video downlink. They also need a return channel for telemetry, status information, commands, or other data.
Depending on the system architecture, wireless communication equipment can provide video transmission in one direction and data communication in the opposite direction. More advanced configurations may support bidirectional Ethernet and serial data transmission.
When selecting a system, consider:
Whether video and control data must operate simultaneously
Required Ethernet and serial interfaces
Available bandwidth and data throughput
Communication range and antenna configuration
Network topology and number of connected nodes
Latency and reliability requirements
For projects requiring two-way communication, please provide your expected data rate, interface requirements, frequency band, and transmission distance so that a suitable configuration can be evaluated.
4. Mesh, MANET, and FHSS Radio Links
Mesh and MANET radio systems are designed for networked wireless communication, while FHSS uses frequency hopping to change operating frequencies according to a defined hopping scheme.
These technologies address different communication requirements:
Mesh networking: Supports communication across interconnected radio nodes.
MANET: Enables mobile nodes to form and maintain an ad hoc network.
FHSS: Uses frequency hopping as part of a radio transmission strategy.
Point-to-point radio links: Connect two communication endpoints over a wireless link.
The most suitable technology depends on network size, mobility, throughput, latency, frequency regulations, and the required communication topology.
If your project needs a multi-node wireless network or a customized telemetry link, contact us with your network diagram and technical requirements.
5. Video Encoder Boards and IP Streaming
Wireless transmission equipment is only one part of a complete video system. In many projects, the camera signal must first be converted into a digital network stream before it can be transmitted over Ethernet or a wireless radio link.
We also provide access to embedded video encoder and decoder boards through iVcan.com.
Available product categories include:
HDMI to IP Ethernet encoder boards
CVBS and analog video to IP encoders
SDI to IP video encoders
USB UVC camera to IP streaming modules
Multi-channel video encoder boards
IP video decoder boards
Depending on the product, supported features may include H.264/H.265 encoding, RTSP or UDP streaming, Ethernet connectivity, serial control, and customized firmware.
These modules can be used as part of a larger wireless video system, allowing a camera signal to be encoded, transported over an IP network, and decoded at the receiving end.

6. Customized Wireless Video Solutions
Standard products do not always meet the requirements of a specific project. Depending on the product and engineering feasibility, customization may be available for:
RF frequency and bandwidth
Transmitter and receiver configuration
Video and data interfaces
RF connectors and antenna arrangements
Power supply and mechanical dimensions
Hardware and firmware functionality
Embedded encoder and decoder integration
We recommend discussing technical requirements before selecting a product, especially when the project involves a special frequency band, strict latency limits, unusual interfaces, or integration into an existing device.

7. How to Choose the Right Wireless Video System
To help identify a suitable solution, please prepare the following information:
Application: What equipment or system will use the wireless link?
Transmission distance: What range is required?
Operating environment: Will the link operate with clear line of sight, partial obstructions, or mobile endpoints?
Video input and output: HDMI, SDI, CVBS, Ethernet, or another interface?
Data communication: Is a return channel or bidirectional data transmission required?
Frequency band: Which frequencies are available and permitted for your application?
Latency and resolution: What are the required video resolution, frame rate, and maximum acceptable delay?
Quantity: How many samples and production units do you expect to need?
Providing these details helps us evaluate the technical requirements and recommend a suitable product or customized configuration.
Frequently Asked Questions
What is the maximum transmission distance?
There is no single distance applicable to every wireless video system. Achievable range depends on transmitter power, receiver performance, antennas, operating frequency, bandwidth, terrain, interference, and regulatory limits. Please provide your operating conditions for a more meaningful evaluation.
Can wireless video and telemetry data be transmitted together?
Some systems support video and data transmission together, while others are designed primarily for video or data. The correct configuration depends on the required interfaces, throughput, network architecture, and whether bidirectional communication is necessary.
Can you customize the operating frequency?
Frequency options depend on the radio platform and its hardware design. Please specify your required frequency range and destination market so that availability and regulatory requirements can be reviewed.
Can I use an IP video encoder with a wireless transmitter?
Yes, this is a common system architecture when the wireless link supports Ethernet or a compatible IP transport method. The encoder, radio link, and receiver must use compatible network interfaces, protocols, bandwidth, and video settings.
Do you support OEM and ODM projects?
Customization may be available depending on the product, project requirements, development resources, and order quantity. Please share your technical specifications and expected quantity for evaluation.
