£429.00 inc VAT

The Smart-e 444K-925 is ideal for extending any HDMI signal beyond its standard 5m length to an impressive 150m of Cat cable whilst maintaning all the necessary auxillary communication data like CEC and DDC for correct EDID reading and HDCP. The 444K-925 has extra features to make life easier for the installer: integral looping HDMI inputs at the transmitter and de-embedded audio at the receiver minimise the need for additional products.

Data Sheet


The 444K-925 is a flexible and cost effective HDBaseT pair solution for extending HDMI, bi-directional IR, full duplex RS232 together with POC (remote power over cable). The unit is very compact and comes with the IR accessories. By incorporating an extended HDBaseT technology, 4K UHD HDMI signals can be transmitted up to 120m and 1080p @60Hz video up to 150m using CAT 6/6A STP/FTP.

The 444K-925 is a pair of TX/RX HDBaseT extenders capable of transmitting UHD HDMI signals up to 4K UHD resolutions. Implementing a special extended version of the HDBaseT specification, the extender also provides the pass through of wide band bi-directional InfraRed signals and full duplex RS232 up to 115Kbaud. Whilst POC power (24V) can be sent by either the TX or RX through the Cat 6 cable to provide power to the remote end. All that is required is a single Cat 6 cable connection to provide all these features.

The 444K-TX925 transmitter comes with looping HDMI inputs providing a convenient method of connecting a local monitor or cascading to another transmitter. Whilst the 444K-RX925 receiver has an analogue stereo audio output replicating the de-embedded audio from the HDMI signal.

Both units Transmitter & Receiver are very compact having a height of only 18mm helping hide the units in confined spaces. Each box also has integral mounting feet for desktop use and the ability to fix right-angled brackets allowing ease of installation.

The Smart-e 444K-925 HDMI extender is a cost-effective long range professional extender using a single CAT 6 distribution system for commercial, education and residential use. It is capable of distributing high resolution UHD HDMI video together with IR and RS232 over a single CAT 6 screened twisted pair cable up to 150m.
