Professional-Grade Construction
Built for continuous operation in commercial environments with rack-mountable form factor and durable black housing. The compact design conserves space in equipment racks or behind displays.
- TAA compliant for government procurement
- RoHS, REACH, and WEEE environmental compliance
- Manufactured in Taiwan with quality components
Deployment / Use Cases
This HDMI extender is engineered for scenarios where display placement is constrained by distance limitations of standard HDMI cables. In corporate environments, it enables presentation systems in large conference rooms where the source equipment must remain secured at a central location while the display mounts on a distant wall. Educational institutions benefit from extending instructor workstation signals to multiple classroom displays without signal degradation.
Digital signage installations utilize these extenders to place media players in secure equipment rooms while transmitting content to displays in lobbies, retail spaces, or outdoor kiosks. Home theater enthusiasts can conceal AV components in cabinets or closets while delivering high-definition content to ceiling-mounted projectors or wall-mounted televisions across room boundaries. The 165-foot reach accommodates most residential and commercial floor plans while maintaining Full HD quality.
Conference Room Solutions
Extend laptop or media player signals to wall-mounted displays in large meeting spaces while keeping source equipment at the presentation podium for easy access.
Digital Signage Distribution
Centralize media players in secure equipment racks while distributing content to multiple displays throughout facilities using existing Cat5e/6 infrastructure.

User Manual
FAQ
What is the maximum distance this HDMI extender can transmit signals?
The ST121SHD50 extends HDMI signals up to 164.04 feet (50 meters) when using quality Cat5e or Cat6 Ethernet cable. This distance accommodates most commercial and residential installation scenarios, allowing source equipment placement in secure locations while displaying content on remotely mounted screens.
Does this extender support 4K or higher resolutions?
No, this extender is designed for Full HD (1080p) content with a maximum resolution of 1920x1080. It maintains signal integrity for standard high-definition video and audio, making it suitable for extending content from most media players, computers, and set-top boxes that output 1080p signals.
What does 'Power Over Cable' mean for installation?
Power Over Cable allows both the transmitter and receiver units to receive power through the same Ethernet cable from a single universal power adapter. This eliminates the need for separate power supplies at each end of the extension, reducing cable clutter, installation complexity, and potential points of failure in the system.
Can I use existing Cat5e network cables for this extender?
Yes, the extender is compatible with both Cat5e and Cat6 twisted-pair Ethernet cables. You can utilize existing structured cabling infrastructure, though for optimal performance over the full 165-foot distance, we recommend using solid-core cable rated for the length of your installation rather than patch cables.
What mounting options are included with this kit?
The kit includes two mounting brackets for rack installation in standard 19-inch equipment racks, plus two sets of foot pads for tabletop placement. This flexibility allows installation in professional AV racks, on shelves, or behind displays depending on your space requirements and deployment scenario.
Is this HDMI extender compatible with audio signals?
Yes, the extender transmits both video and audio signals embedded in the HDMI stream. It supports standard HDMI audio formats, allowing you to extend content with synchronized sound to remote displays with built-in speakers or connected audio systems without requiring separate audio cabling.
