Wireless video transmitter module

Types of wireless video transmitter modules

A wireless video transmitter module is a device that sends video signals to wireless receivers. Its technology has advanced rapidly in recent years, with many products available in the consumer and professional markets. Wireless video transmitters can send signals to long distances, typically more than 1 kilometer, depending on the model, and can provide high-definition video output. Many of these transmitter modules include antennas for signal transmission and HDMI input for connecting cameras or other video sources.

The modules are small and lightweight, making them ideal for applications like video monitoring, drone filming, and live event broadcasting. Some modules even include control signals so users can operate the camera remotely over the same wireless link used for video transmission. Buyers can check different kinds of transmitter modules available in the market. They include:

• WiFi video transmitters: These devices use wireless local area network (WLAN) technology to connect video sources and displaying monitors. They have limited transmission distances and are not suitable for video links between far-separated locations.
• Long-range digital transmitters: These transmitters can send video signals over long distances (more than 10 km). They encode and modulate the video signal to improve range, reduce interference, and provide good picture quality. Long-range transmitters are often used for applications like FPV (first-person view) drone flying or remote monitoring in which the video receiver is far from the video source.
• Analog video transmitters: These transmitter modules modulate the video signal onto a radio frequency (RF) carrier signal. They are less expensive than digital transmitters but provide worse picture quality and have lower resistance to interference. Analog transmitters are often used for older equipment or applications where cost matters more than picture quality.
• Hybrid video transmitters: These transmitters combine the benefits of both analog and digital technologies. They provide better picture quality and longer range than purely analog systems while being more affordable than fully digital ones.
