4K HDMI over IP Receiver

The StarTech ST12MHDLAN4R receives HDMI video over a Gigabit LAN and outputs up to 3840x2160 at 30 Hz. It is built for installers extending 4K signals up to 100 m using Cat 5e or better cabling. The unit supports video walls, multi-display presentations and point-to-multipoint distribution. It requires the matching ST12MHDLAN4K transmitter kit to operate.

Thermals noise and power draw

The aluminium enclosure dissipates heat without a fan, so the receiver runs silently in 0 to 40 °C environments. Power consumption is rated at 18 W from the included 12 V 1.5 A adapter, which accepts 100 to 240 V AC input. Humidity tolerance spans 0 to 80 % non-condensing for reliable operation in typical indoor installations.

Bundled accessories and software

A universal power adapter with NA, EU, UK and ANZ plugs, a mounting bracket, a Cat 5e cable, an RJ11 to RS-232 adapter, an RJ11 cable and a plastic screwdriver are included. The free iOS and Android app enables video wall layout and switching control from a mobile device. A quick-start guide covers initial network configuration and pairing with the transmitter.

Questions about this item

How do I mount the ST12MHDLAN4R and what step is often missed?

Attach the included mounting bracket to a surface, then secure the receiver to the bracket. The step often missed is connecting the RJ-11 to RS-232 adapter and cable for serial control before finalising the mount.

What maintenance or replacement will the ST12MHDLAN4R need later?

The unit has no user-serviceable parts. Long-term care is limited to keeping ventilation clear within the 0 to 40 °C operating range and replacing the external 12 V DC power adapter if it fails.

What limit appears first during sustained 4K use of the ST12MHDLAN4R?

The 30 Hz refresh ceiling at 3840x2160 resolution is the primary constraint. The receiver also draws 18 W continuously, so adequate airflow must be maintained to stay within the 40 °C operating maximum.
