In real-world video surveillance and embedded systems, 에이 CVBS to IP video converter is often more than just an encoder. Many projects require it to act as a control hub, integrating external hardware such as IR illuminators, 릴레이, and UART-controlled devices.
이 기사에서는, we’ll walk through a real customer inquiry, analyze the technical requirements, and explain how these features can be implemented through custom development.
Customer Inquiry (Original Message)
A customer using our CVBS encoder board raised the following questions:
1. Alarm/control output via GPIO:
I would like to use the alarm output (GPIO) to control an external flashlight/IR illuminator. I need to be able to turn it on by sending a command (via any supported interface — HTTP API, MQTT, 또는 기타), and have it remain on until I send another command to turn it off. Is this feature supported? Is there any documentation or API reference for remote control of the alarm output?
2. UART-controlled video selector:
I can see that the web interface has a “UART Settings” section with a “UART Test” 기능. I am planning to connect a UART-controlled video selector to the board. All cameras connected to the selector output video in the same format (CVBS), so the board itself will not need to handle any format switching — UART commands will only change the active input on the selector.
Is it possible to remotely send UART commands to the selector (via HTTP API, MQTT, or any other supported method)? Is there any documentation for this use case?목차

Technical Requirement Analysis
This request goes beyond basic video encoding. The customer is essentially trying to build a network-controlled embedded system with the following capabilities:
1. Remote GPIO Control (Digital Output)
The customer wants:
- Remote ON/OFF control of a GPIO pin
- Control via network interfaces (HTTP, MQTT, 기타)
- Persistent state (not just a trigger pulse)
This means the GPIO must function as a latched digital output, similar to a relay.
Typical use cases include:
- IR illuminator control
- Alarm devices
- External lighting systems
2. UART over Network (투명한 전송)
The second requirement is more advanced.
System architecture:
Multiple Cameras → Video Selector (UART controlled) → CVBS → Encoder → IP Stream
The encoder does not switch video inputs itself. 대신에:
- 에이 UART-controlled video selector determines which camera is active
- The encoder must forward remote commands to UART
This requires a network-to-UART bridge 능력.
3. API and Integration Expectations
The customer clearly expects:
- HTTP API or MQTT interface
- Command-based control
- Documentation for integration
This indicates the customer is likely:
- A system integrator
- Developing a scalable or commercial solution
What the Customer Really Needs
Summarizing the request:
- GPIO as a remotely controlled switch
- UART as a remote command channel
- The encoder acting as a control gateway, not just a video device

자주하는 질문
큐: I need to send binary numbers and control commands in both directions. Can your converter board support this?
에이: 예, our converter (인코더) board fully supports bidirectional communication of binary data and control commands.
작동 원리:
- The board is equipped with a standard serial interface:
텍사스 (부치다), RX (받다), and GND (지면). - It can be connected to a remote computer via an Ethernet cable (랜).
- Through this connection, the system enables two-way transmission of serial data, including binary values and control commands.
요구사항:
- Serial Communication Software
You will need to run a serial communication tool on your computer (예를 들어, a terminal or custom software) to send and receive commands. - IP Address Configuration
- The converter board and the computer must be configured with each other’s IP 주소.
- Proper network setup ensures reliable communication between both devices.
주요 특징:
- 지원 전이중 (양방향) 의사소통
- 호환 가능 binary data and command-based protocols
- Easy integration with existing serial systems
- Remote communication over standard network infrastructure
일반적인 사용 사례:
- Remote device control
- 산업 자동화 시스템
- Data acquisition and monitoring
- Embedded system communication
큐: Why is the board receiving data but TCP communication is not working correctly?
에이: Please check your TCP Server IP setting. The browser address (예를 들면, 192.168.1.188) is the encoder board’s IP address, but the TCP Server IP should be your computer’s IP address instead. Using the same IP for both may cause communication failure or IP conflicts.
