About the StarTech.com HDMI Over IP Extender Kit - Video Over IP Extender with Support for Video Wall - 4K

View user manual

Distribute 4K 30Hz HDMI signals across your existing IP network with this high-performance AV over IP extender kit. Designed for IT professionals, system integrators, and digital signage specialists, this solution delivers unmatched flexibility for scaling video distribution without the limitations of traditional HDMI splitters or fixed extenders.

Scalable HDMI Over IP

Easily expand your A/V distribution setup and build dynamic video walls using the ST12MHDLAN4K extender kit and additional receivers (ST12MHDLAN4R , sold separately):

  • One-to-Many: Connect up to 16 receivers to a single transmitter, ideal for broadcasting HDMI over IP to multiple displays
  • Many-to-Many: Integrate up to 16 ST12MHDLAN4K extender kits and additional ST12MHDLAN4R receivers with a maximum of 16 transmitters and 256 receivers.

For smaller-scale deployments, the extender kit can be used in a simple point-to-point setup over Cat5e/6 cabling up to 330 ft (100 m), with support for extending two independent 3.5 mm audio sources to remote speaker systems.

Centralized Video Control App

The included iOS/Android Video Control App empowers administrators to name sources and displays, switch inputs, and configure video walls, all from a mobile device. With RS232 passthrough, TVs or serial-controlled devices can be managed remotely through the same network.

Flexible Installations for Any Environment

Perfect for digital signage in retail, hospitality, and corporate settings, as well as command centers or other mission-critical environments. The kit includes mounting hardware for clean shelf or rack installations and supports both static and dynamic signage needs.

Note: For optimal performance, a managed network switch with IGMP is recommended when using more than one transmitter or more than four receivers. Non-managed switches may impact the performance of other devices on your network. Jumbo frames support must be enabled to stream 4K video effectively.
