KAMEHA KA263TX HDMI Over IP Matrix Transmitter 4K@60Hz (120M) – IP Colour Series

---

🔹 Product Introduction

The KAMEHA KA263TX HDMI Over IP Matrix Transmitter is a high-performance 4K@60Hz AV over IP solution designed for scalable and professional AV distribution systems. Built on advanced ipcolor STREAM™ technology, it delivers high-definition video with low latency over a standard IGMP Gigabit network switch.

As part of the KA263 IP Matrix system, the transmitter enables switching, extending, and distributing HDMI audio and video signals to up to 253 receiving terminals, supporting up to 100 signal sources within a flexible many-to-many matrix architecture.

With transmission distances up to 120 meters over Cat6 cable, the KA263TX is ideal for large-scale installations such as conference systems, control centers, broadcasting studios, transportation hubs, and education environments.

🔹 Product Description

The KA263TX functions as the signal source encoder within the HDMI Over IP matrix ecosystem. It converts HDMI input signals into IP streams that can be distributed over a standard Gigabit network infrastructure.

Supporting full 4K@60Hz (3840×2160) resolution with 18Gbps bandwidth, it ensures crystal-clear image quality and stable low-latency transmission (70–180ms).

Key System Capabilities:

• Up to 100 signal inputs

• Up to 253 signal outputs

• One-to-one and many-to-many routing

• Switch cascading for system expansion

• Video wall splicing up to 5×5 (APP controlled)

The transmitter also features:

• HDMI local loop out for monitoring

• Bi-directional IR passback (20–60KHz)

• RS-232 command control

• I/O interface control

• POE (Power over Ethernet) support

Designed for 24/7 stable operation, the system integrates lightning protection, surge protection, and ESD protection for enhanced reliability.
