This commercial-grade AV transmission device is a dedicated HDMI via CAT5e/6 Extender 120M with IR,
designed as a paired system (transmitter TX + receiver RX) to solve the limitation of traditional HDMI cables’
short transmission range. As an HDMI via CAT5e/6 Extender 120M with IR, it specializes in extending HDMI
audio and video signals via cost-effective CAT5e/6 network cables, while integrating IR infrared return transmission
functionality—ideal for professional scenarios requiring long-distance signal delivery and remote source control.
The HDMI via CAT5e/6 Extender 120M with IR enables stable transmission of HDMI audio and video signals to
user-end displays over a single CAT5e or CAT6 cable, with a maximum transmission distance of up to 120 meters.
It supports uncompressed signal transmission, ensuring no loss of image clarity, color accuracy, or audio
synchronization—critical for high-demand applications where signal fidelity directly impacts user experience.
A key functional advantage is its IR infrared return transmission: it allows users to remotely control signal source
devices (such as TV boxes, media players, or set-top boxes) from the receiver end via IR signals, eliminating the
need for on-site operation of source equipment and greatly enhancing operational flexibility.
Equipped with built-in commercial-grade EDID (Extended Display Identification Data) management, the HDMI via
CAT5e/6 Extender 120M with IR automatically reads and synchronizes display parameters (resolution, refresh rate,
and audio format) between the HDMI source and connected devices (monitors, LCD splicing screens, LED displays,
or projectors). This significantly improves compatibility across diverse brands and models of AV equipment, effectively
avoiding common issues like signal mismatch, black screens, or audio dropouts—ensuring seamless integration into
existing AV systems.
In addition to performance reliability, the extender offers practical user benefits: it leverages existing CAT5e/6 wiring
infrastructure, reducing cable procurement and deployment costs; its plug-and-play design requires no software
configuration or professional technical expertise, simplifying installation and shortening project cycles. It also
incorporates electromagnetic interference (EMI) and radio frequency interference (RFI) shielding, ensuring stable
signal transmission even in complex electrical environments (e.g., near security monitoring equipment, power
distribution cabinets, or dense wiring closets).
With its long 120-meter transmission distance, low use cost, convenient installation, and strong compatibility,
the HDMI via CAT5e/6 Extender 120M with IR is widely applied in professional projects: information release
systems (shopping malls, airports), security monitoring centers (connecting cameras to remote displays), video
conferencing systems (corporate meeting rooms, conference centers), HD teaching systems (smart classrooms,
lecture halls), LCD/LED splicing large screens (exhibition halls, command centers), and engineering projection
fusion projects (event venues, theaters). It serves as a stable, efficient, and cost-effective transmission solution
for both commercial and industrial AV infrastructure, meeting the diverse needs of professional engineering
applications.
