Understanding the Customer’s Core Demand

When a customer requests “an video transmission module with a LAN input and one or two data cables supporting a maximum baud rate of 115200”, their requirement actually reveals several engineering priorities:

Network-based video interface (LAN input)
The customer likely has an IP video source — for example, an IP camera or encoder — and needs to inject this stream into a wireless system. The LAN input ensures compatibility with RTSP, ONVIF, or SRT protocols commonly used in video transmission.
Dual serial channels for telemetry or control
The mention of “one or two data cables” points to UART interfaces used for telemetry, remote control, or data synchronization between devices. A 115200 bps limit indicates typical control-signal usage rather than bulk data transfer.
Wireless video transmission environment
Although not explicitly stated, this type of module is almost always used in wireless image transmission — drones, robotic systems, and mobile surveillance units — where both video and command data must travel together.
Low latency and high reliability
Customers in these fields usually prioritize minimal delay, stable communication, and seamless integration with existing LAN-based control systems.

Technical Features of a LAN Video + UART Wireless Module

A well-designed LAN video + UART transmission module integrates both network and serial communication in a single hardware platform. Typical technical features include:

1. LAN Interface

10/100/1000 Mbps RJ45 Ethernet port for video input/output
Supports RTSP / RTMP / SRT / ONVIF protocols
Configurable IP (DHCP or static)
Option to bridge LAN video stream to COFDM, Wi-Fi, or 4G/5G wireless modules

2. UART Serial Communication

Why Combine LAN Video and UART in One Wireless System?

1. Unified Transmission:
Traditional systems often require separate radio channels — one for video, another for control data. Combining them reduces complexity and interference, enabling seamless integration.

2. Reduced Latency:
Using one shared wireless carrier for both signals cuts down transmission delay, critical for UAVs and robotic operations.

3. Lower Cost and Weight:
In drones or portable systems, every gram and watt matter. A single module with both video and UART saves power and reduces hardware volume.

4. Simplified Integration:
The LAN interface provides plug-and-play compatibility with IP cameras and NVRs, while UART channels handle sensor or control communication — all through one unified data link.

Potential Customer Scenarios

1. UAV / Drone Systems

For drones performing aerial inspection or surveillance, the onboard camera sends HD video to the ground station via LAN. At the same time, telemetry (altitude, GPS, gimbal angle) travels through UART. A combined LAN + UART transmission system ensures smooth control and clear real-time visuals.

2. Mobile Surveillance Vehicles

In police, firefighting, or broadcasting vehicles, multiple cameras feed video to a command center. The UART channel is used to control PTZ cameras or onboard sensors through the same wireless link.

3. Industrial Inspection Robots

Factory or tunnel inspection robots rely on both image and control data. LAN handles video streaming, while UART relays sensor or robotic arm feedback to the operator.

4. Military or Tactical Communication

Low-latency H.265 COFDM links are used for secure field video. UART channels carry encrypted commands or telemetry, maintaining mission control under interference.
