Leverage your existing network infrastructure to create scalable, cost-effective AVoIP solutions

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

Scalable HDMI over IP

Easily expand your A/V distribution setup and create dynamic video walls with the ST12MHDLAN4K extender kit and additional receivers (additional receivers, 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 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 configuration via Cat5e/6 cabling up to 100m, with support for extending two independent 3.5mm audio sources to remote speaker systems.

Centralized Video Control App

The included video control app for iOS/Android allows administrators to name sources and displays, switch inputs, and configure video walls, all from a mobile device. With RS232 pass-through, TVs or serially controlled devices can be managed remotely over the same network.

Flexible Installations for Any Environment

Perfect for digital signage in retail, hospitality, and corporate environments, as well as command centers or other mission-critical settings. The kit includes mounting hardware for clean installations on shelves or in racks and is compatible with both static and dynamic signage needs.

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