One-Way COFDM Wireless Video Transmitter for IP Camera – 5W, 4K HDMI, H.265/H.264

Overview

The One-Way COFDM Wireless Video Transmitter for IP Camera is a professional wireless video transmission solution designed for remote monitoring, industrial applications, mobile platforms, and security systems.

Featuring a built-in 5W RF power amplifier, this transmitter receives video streams from compatible IP cameras through Ethernet and supports HDMI video input up to 4K at 30 fps. It encodes video using H.264 or H.265 compression and transmits it over a COFDM wireless link to a compatible receiver.

Unlike systems that require a bidirectional IP network between the camera and monitoring station, this solution provides a dedicated one-way wireless video link. It is suitable for applications where video needs to be transmitted from a remote location without requiring a return network connection.

With AES-256 encryption, configurable RF parameters, and support for non-line-of-sight (NLOS) and mobile transmission, the 1726-4K-IP-Camera-link offers a flexible solution for professional wireless video projects.

How It Works

The 1726-4K-IP-Camera-link converts a compatible IP camera's RTSP stream into a one-way COFDM wireless video link.

System connection:

IP Camera → Ethernet → COFDM Video Transmitter → Wireless COFDM Link → Compatible COFDM Receiver → Monitor

For HDMI applications, connect a compatible HDMI video source to the transmitter instead of using the IP camera input.

The transmitter encodes the incoming video and sends it wirelessly to a compatible receiver for decoding and display.
