4TX-1RX Full HD Wireless Video Transmission System

A multi-functional, multi-channel wireless video transmission system operating in the 5GHz band. It supports the simultaneous wireless transmission of 4 channels of video, audio, Tally signals, and PTZ control. With a maximum video resolution of 1080P60, it enables the wireless transmission of video signals from four cameras to a receiver. This system is suitable for a wide range of applications, including UAV video transmission, commercial live streaming, sports event broadcasting, film and television production, campus TV stations, and multimedia education.

  • Each channel supports a transmission distance of up to 1000 meters.
  • Four transmitters share one wireless channel, enhancing anti-interference performance and signal stability.
  • Simultaneous SDI and HDMI input/output across four channels.
  • Supports tally, timecode, and instant replay functions for efficient live operation.
  • Compatible with RTSP network pull stream for flexible IP workflow integration.
  • Supports RS232/RS422 passthrough, allowing remote device control (e.g. PTZ cameras) via receiver.
  • AES-128 encryption ensures data privacy and transmission safety.
  • Constructed from high-strength aluminum alloy, offering durability and high system integration for field use.
